Understanding the Enemy: Identifying Draft Sources in Your Doors

Before you can effectively combat drafts and start saving money, it's crucial to understand exactly where these energy-sapping leaks are originating. A thorough inspection is the first and most important step in any DIY door sealing project. Don't jump into repairs without first playing detective!

This section will guide you through the process of identifying draft sources around your doors, ensuring you target your efforts for maximum impact.

The Art of the Draft Check

The simplest method for identifying drafts is, quite simply, to use your senses.

Visual Inspection: Begin by carefully examining your doors and door frames. Look for visible gaps or cracks, especially where different materials meet. Pay close attention to areas where the door frame connects to the wall, as these are common points of failure.

The Feel Test: On a cold or windy day, walk around your closed doors and feel for air movement. Run your hand along the edges of the door, paying particular attention to the areas around the frame and the bottom of the door. You should be able to easily detect even small drafts. If you cannot feel a draft on an otherwise windy day, then it's likely well-sealed.

Common Problem Areas: Where Drafts Lurk

While drafts can appear in unexpected places, certain areas are particularly prone to air leakage:

Around the Door Frame: The door frame (including the jamb and threshold) is a major entry point for drafts.

The jamb, the vertical sides of the frame, can develop gaps over time due to settling or warping.

The threshold, the horizontal piece at the bottom of the frame, is another common area for drafts, especially if it's not properly sealed or if the door doesn't sit flush against it.

Under the Door: A significant gap under the door is a prime suspect for drafts. This is especially true for exterior doors exposed to the elements. Cold air rushes in unimpeded, negating even the best insulation efforts.

Between the Door and the Jamb: Even with a seemingly well-fitted door, gaps can exist between the door itself and the surrounding jamb. This is often due to issues with the door's alignment or the weatherstripping.

Exterior Doors: The Front Line of Defense

It's important to note that these inspection techniques are especially relevant for exterior doors. These doors act as the primary barrier between your home and the outside elements, making them the most vulnerable to drafts and energy loss. Pay particular attention to the sealing around exterior doors, as addressing these leaks will have the most significant impact on your energy bills and home comfort.

Gathering Your Arsenal: Essential Tools and Materials

Now that you've identified the drafty culprits around your doors, it's time to equip yourself with the right tools and materials to wage war on air leaks. This section details everything you'll need for a successful DIY door sealing project, highlighting important considerations for each item. Choosing the right components is crucial for both effectiveness and longevity.

Essential Tools for the Job

Having the right tools will make the job significantly easier and produce more professional-looking results. Don't skimp on quality here; durable tools will last for future projects.

• Measuring Tape: Accurate measurements are paramount for cutting weatherstripping and door sweeps to the correct size. A standard measuring tape, at least 12 feet long, will suffice.

• Utility Knife: A sharp utility knife is indispensable for scoring and cutting weatherstripping, caulk tubes, and other materials. Retractable models with replaceable blades are the safest and most convenient. Always use a fresh blade for clean, precise cuts.

• Screwdriver (Various Types): You'll likely encounter different types of screws during your door sealing project, especially when installing door sweeps or weatherstripping. A set of screwdrivers with both Phillips head and flat head options is essential. Consider a multi-bit screwdriver for versatility. Magnetic tips are helpful for preventing screws from dropping.

• Caulk Gun: A caulk gun is necessary for applying caulk neatly and efficiently. Choose a ratcheting caulk gun for smooth, consistent dispensing. A dripless model can prevent messy drips and wasted caulk. Practice on a piece of cardboard before applying caulk to your door frame.

Necessary Materials for Sealing Success

Selecting the appropriate materials is just as crucial as having the right tools. Consider the specific location and size of the gaps you're trying to seal.

Caulk (Appropriate for Exterior Use)

Caulk is used to seal gaps and cracks around the door frame. It's crucial to choose a caulk specifically designed for exterior use, as these are formulated to withstand weather exposure.

• Types of Exterior Caulk: Look for silicone, acrylic latex, or polyurethane caulk. Silicone offers excellent water resistance and flexibility, while acrylic latex is paintable and easier to clean up. Polyurethane provides superior adhesion and durability.
• Color Matching: Choose a caulk color that matches your door frame for a seamless appearance. White, clear, and brown are common options.
• Application Tips: Apply caulk in a smooth, even bead, and immediately smooth it with your finger or a caulk smoothing tool for a professional finish.

Weatherstripping (Various Types)

Weatherstripping is used to create a seal between the door and the door frame, preventing air from leaking through gaps. Different types of weatherstripping are suitable for different door types and gap sizes.

• Foam Weatherstripping: This is an inexpensive and easy-to-install option, suitable for filling small gaps. It comes in various thicknesses and can be self-adhesive or require adhesive application. However, foam weatherstripping is not as durable as other options and may need to be replaced more frequently.
• Felt Weatherstripping: Similar to foam, felt is an affordable option for smaller gaps. It's easy to cut and install, but it's not very durable and prone to wear and tear.
• Rubber Weatherstripping: Rubber weatherstripping offers better durability than foam and felt. It comes in various profiles, including D-shaped, P-shaped, and V-shaped. Choose a profile that matches the gap size and shape between your door and frame. Some rubber weatherstripping is self-adhesive, while others require nails or staples for installation.
• Metal Weatherstripping: Metal weatherstripping, such as spring bronze or magnetic weatherstripping, is the most durable option. It provides a tight seal and can withstand years of use. However, it's more expensive and requires more skill to install.

Door Sweep

A door sweep is attached to the bottom of the door to seal the gap between the door and the threshold. This is especially important for exterior doors to prevent drafts and keep out pests.

• Types of Door Sweeps: Door sweeps come in various materials, including rubber, silicone, and brush. Rubber and silicone sweeps provide a tight seal against the threshold, while brush sweeps are better for uneven surfaces.
• Installation: Measure the width of your door and cut the door sweep to the correct length. Position the sweep against the bottom of the door and attach it securely with screws or adhesive, following the manufacturer's instructions. Make sure the sweep makes contact with the threshold when the door is closed.

Before you can begin banishing those pesky drafts, you need to arm yourself with the correct materials. Now, let's move on to the crucial step of sealing those identified gaps.

Sealing the Deal: Applying Caulk to Gaps in the Door Frame

Caulking is a fundamental technique for sealing gaps around your door frame, preventing air infiltration and improving energy efficiency. This section provides a detailed guide to applying caulk effectively, ensuring a professional and long-lasting seal.

Preparation is Key: Cleaning the Surface

The first step in achieving a successful caulk application is thorough surface preparation.

Remove any old caulk, dirt, dust, debris, or paint chips from the areas you intend to caulk.

A putty knife or scraper can be used to remove old caulk, and a wire brush helps to remove loose particles.

Once the area is clear of debris, wipe it down with a damp cloth and allow it to dry completely.

A clean, dry surface will ensure that the caulk adheres properly and creates a strong, airtight seal.

Loading and Readying the Caulk Gun

Loading the caulk gun properly is essential for smooth and controlled application.

First, retract the plunger fully by pulling back on the release lever.

Insert the caulk tube into the gun carriage, ensuring that the nozzle is facing forward.

Next, use the metal spike attached to the caulk gun to puncture the seal at the tip of the caulk tube.

Finally, advance the plunger until it makes contact with the bottom of the caulk tube.

To begin, make a small cut at an angle on the tip of the caulk tube. The size of the opening will determine the width of the caulk bead. Start small; you can always enlarge the opening if needed.

Applying the Caulk Bead

Hold the caulk gun at a 45-degree angle to the surface and apply a consistent, even bead of caulk along the gap.

Squeeze the trigger gently and move the gun smoothly along the seam. Avoid stopping and starting, as this can create unevenness in the caulk line.

Apply steady pressure and maintain a consistent speed to ensure a uniform bead.

For wider gaps, you may need to apply multiple passes of caulk.

If the gap is extremely wide (over 1/4 inch), consider using backer rod – a foam material that fills the majority of the gap before caulking.

This will prevent the caulk from sinking too deeply and provide a solid backing for a more durable seal.

Smoothing the Caulk Line

Once you've applied the caulk, it's important to smooth the bead for a clean, professional finish.

There are two primary methods for smoothing caulk:

Finger Smoothing

The simplest method is to use your finger. Dip your finger in water mixed with a drop of dish soap to prevent the caulk from sticking. Gently run your finger along the caulk line, applying light pressure to smooth it out. Wipe any excess caulk from your finger onto a damp cloth.

Tool Smoothing

Alternatively, you can use a caulk smoothing tool. These tools come in various shapes and sizes and can help you create a perfectly smooth and consistent caulk line. Simply run the tool along the caulk bead, applying gentle pressure to shape and smooth it.

Drying and Curing

Allow the caulk to dry completely according to the manufacturer's instructions. Drying times can vary depending on the type of caulk and the environmental conditions. Typically, it takes 24-48 hours for caulk to fully cure. Avoid touching or disturbing the caulk during the drying process. Once the caulk is fully cured, it will form a flexible, airtight seal that will help to keep drafts at bay and improve the energy efficiency of your home.

With those gaps around the door frame sealed tight, the next line of defense against drafts involves addressing the perimeter where the door itself meets the frame. This is where weatherstripping comes into play.

Weatherstripping Wonders: Installing or Replacing Weatherstripping

Weatherstripping acts as a gasket, creating a tight seal between the door and the frame to prevent air from leaking through. Over time, weatherstripping can become worn, cracked, or compressed, losing its effectiveness. Replacing it is a relatively simple DIY task that can significantly improve your home's energy efficiency.

Understanding Weatherstripping Types

The first step in tackling this project is understanding the different types of weatherstripping available. Each has its strengths and weaknesses, making them suitable for different door types and situations.

• Foam Weatherstripping: Typically the most inexpensive option, foam weatherstripping is easy to install as it usually features an adhesive backing. However, it's also the least durable and prone to compression and tearing over time. Ideal for doors that aren't used frequently.

• Felt Weatherstripping: Similar to foam in terms of cost and ease of installation, felt weatherstripping offers a slightly better lifespan. It's also less resistant to moisture and can become matted down with repeated use.

• Rubber Weatherstripping (EPDM or Silicone): Rubber weatherstripping offers a good balance of durability and affordability. EPDM rubber is resistant to weathering and compression, while silicone rubber offers even greater temperature resistance. A solid choice for most exterior doors.

• Vinyl Weatherstripping: Vinyl weatherstripping is another durable option that's relatively easy to install. It's often available in various profiles, including those with a magnetic strip for an even tighter seal.

• Metal Weatherstripping (Spring Bronze, V-Strip): Metal weatherstripping is the most durable option, offering decades of reliable performance. However, it can be more challenging to install, often requiring specialized tools and techniques. Best left to experienced DIYers or professionals.

Measuring and Cutting Weatherstripping

Accurate measurement is crucial for a proper seal. Before you start cutting, measure each section of the door frame where you intend to install the weatherstripping.

• Use a measuring tape to determine the length of each side of the door frame (both vertical sides and the top).

• Add a little extra length (about an inch) to each piece to allow for slight errors during installation.

• Use a utility knife or sharp scissors to cut the weatherstripping to the measured length. For metal weatherstripping, you may need metal snips.

Step-by-Step Installation Guide

The installation process varies depending on the type of weatherstripping you choose. Here's a general guide:

1. Prepare the Surface: Clean the door frame thoroughly with a damp cloth and allow it to dry completely. Remove any old adhesive residue or debris.

2. Peel and Stick (for Adhesive-Backed Types): Remove the backing paper from the adhesive strip on the weatherstripping.

3. Position the Weatherstripping: Carefully align the weatherstripping along the edge of the door frame, ensuring it makes good contact with the door when closed.

4. Apply Pressure: Press firmly along the entire length of the weatherstripping to ensure a secure bond.

5. Nailing or Screwing (for Non-Adhesive Types): Some types of weatherstripping require nails or screws for secure attachment. Pre-drill pilot holes if necessary to prevent splitting the wood.

6. Test the Seal: Close the door and check for any gaps or areas where air is still leaking through. Adjust the weatherstripping as needed to achieve a tight seal.

Important Considerations:

• Pay close attention to the corners of the door frame. Miter the weatherstripping at a 45-degree angle for a clean, professional look.
• For doors with uneven gaps, you may need to use weatherstripping of different thicknesses.
• If you're replacing existing weatherstripping, remove the old material completely before installing the new.
• Consider the door's usage. High-traffic doors might need more durable weatherstripping.

By carefully selecting the appropriate type of weatherstripping and following these installation steps, you can effectively seal gaps around your doors, preventing drafts and saving energy.

Sweep It Under the Rug: Installing a Door Sweep for Bottom Gaps

Even with diligent caulking and weatherstripping, a persistent draft can still snake its way into your home – from underneath the door. This is where the humble, yet effective, door sweep comes into play. A door sweep is a simple device designed to seal the gap between the bottom of the door and the threshold, effectively blocking drafts, dust, insects, and even noise.

Choosing and installing the right door sweep can make a significant difference in your home's comfort and energy efficiency.

Selecting the Right Door Sweep

Before you grab just any door sweep off the shelf, consider the different types available and which best suits your needs. The primary types include:

• Brush Sweeps: These feature bristles that conform well to uneven surfaces and are excellent for older homes where the threshold might not be perfectly level. Brush sweeps are generally durable and long-lasting.

• Vinyl Sweeps: Vinyl sweeps offer a good balance of affordability and effectiveness. They create a tight seal against smooth thresholds but may wear down more quickly than brush sweeps, especially with heavy foot traffic.

• Rubber Sweeps: Similar to vinyl, rubber sweeps provide a reliable seal and can withstand more wear and tear. Look for sweeps made from durable rubber compounds for extended lifespan.

• Automatic Door Bottoms: These are more sophisticated sweeps that automatically lower when the door is closed, creating a tight seal and retracting when the door is opened to clear carpets and floors. Automatic door bottoms are generally more expensive and require more involved installation.

Step-by-Step Door Sweep Installation

Regardless of the type you choose, the installation process is generally straightforward. Here’s a step-by-step guide:

Measure the Door Width

Use a measuring tape to determine the exact width of your door. Accuracy is key here; a sweep that's too long will drag and wear out prematurely, while one that's too short won't provide a complete seal.

Cut the Door Sweep to Size

Using a hacksaw or utility knife (depending on the sweep material), carefully cut the door sweep to the measured width. Always err on the side of caution and cut slightly longer than needed; you can always trim more off, but you can’t add material back. A miter saw is ideal if you have one.

Position the Door Sweep

Close the door and position the door sweep against the bottom edge, ensuring it makes firm contact with the threshold. The sweep should compress slightly against the threshold to create a tight seal. Some sweeps are adjustable, allowing you to fine-tune the height for optimal contact.

Mark the Mounting Holes

Using a pencil, mark the locations of the mounting holes on the door. These marks will guide you when attaching the sweep.

Attach the Door Sweep

Most door sweeps are attached using screws. Pre-drill pilot holes at the marked locations to make screwing easier and prevent the wood from splitting. Use screws that are appropriate for the door material (wood, metal, etc.). Some sweeps use adhesive backing. If this is the case with yours, ensure the door surface is thoroughly clean and dry before applying the adhesive.

• If using screws: Align the sweep with the pilot holes and carefully drive the screws in until the sweep is securely attached. Avoid over-tightening, which can damage the sweep or the door.

• If using adhesive: Peel off the protective backing and carefully press the sweep against the door, ensuring it's properly aligned. Apply firm, even pressure for the recommended amount of time to allow the adhesive to bond.

Ensuring a Proper Seal

After installation, open and close the door several times to check for any dragging or resistance. The door should move freely without excessive friction. Inspect the seal between the sweep and the threshold. If there are any gaps, you may need to adjust the height of the sweep or add a thin shim underneath to ensure proper contact.

A well-installed door sweep is a simple yet powerful tool in the fight against drafts, helping you maintain a comfortable and energy-efficient home.

Advanced Techniques: Fine-Tuning for Optimal Sealing (Optional)

Sometimes, despite your best efforts with caulking, weatherstripping, and door sweeps, stubborn drafts persist. These situations often point to underlying issues with the door's alignment or the threshold itself. These advanced techniques, while not always necessary, can provide the final adjustments needed for a truly draft-free entryway. It's important to emphasize that these steps are optional and require a bit more skill and patience. If you're uncomfortable with these types of repairs, it's always best to consult a professional.

Adjusting the Threshold: Creating a Tighter Seal

The threshold, that strip of material at the bottom of the door frame that you step over, plays a crucial role in creating a tight seal. Over time, thresholds can shift, settle, or become worn, leading to gaps and drafts. Many thresholds are adjustable, allowing you to raise or lower them to better meet the door sweep or the bottom of the door itself.

Identifying an Adjustable Threshold

Before you start, determine if you have an adjustable threshold. Look for small screws along the top surface of the threshold, usually spaced several inches apart. These screws, when turned, will either raise or lower the adjustable portion of the threshold.

The Adjustment Process

1. Begin by closing the door and feeling for drafts along the bottom. Note where the gaps are most prominent.

2. Locate the adjustment screws on the threshold.

3. Using a screwdriver that fits the screws, turn them a small amount (usually a quarter or half turn) in the direction that raises the threshold in the area where you feel the draft.

4. Open and close the door to check for smooth operation. You want a tight seal without the door binding or dragging.

5. Repeat this process, making small adjustments and testing the door each time, until you achieve a consistent and tight seal along the entire bottom edge. If you meet resistance or the door gets too difficult to close, you've likely raised the threshold too much. Back off the screws slightly.

Dealing with Non-Adjustable Thresholds

If your threshold isn't adjustable, you have a couple of options. You could replace it with an adjustable model, which involves removing the old threshold and installing a new one. This is a more involved process but can be worthwhile if your existing threshold is significantly worn or damaged. Another option is to add a thin strip of material, such as weatherstripping or a metal shim, to the threshold to raise its height.

Re-Shimming the Door Frame: Correcting Alignment Issues

A door frame that's out of alignment can cause drafts all around the door, not just at the bottom. This misalignment might manifest as the door rubbing against the frame in certain spots, gaps appearing on one side but not the other, or the door simply not closing properly. Re-shimming the door frame can correct these issues, ensuring that the door sits squarely within the frame and creates a consistent seal.

Identifying Alignment Problems

Carefully inspect the door frame. Look for gaps between the frame and the wall, especially near the hinges and strike plate (the metal plate where the door latch engages). Use a level to check if the frame is plumb (perfectly vertical) and square (all corners are 90 degrees). If the frame is significantly out of plumb or square, re-shimming is likely necessary.

The Re-Shimming Process

1. Carefully remove the interior trim around the door frame. This will expose the shims that are already in place.

2. Use a pry bar to gently loosen the door frame from the wall studs. Be careful not to damage the frame or the surrounding drywall.

3. Inspect the existing shims. If they are damaged or missing, replace them with new shims.

4. Using a level, adjust the frame until it is plumb and square. Insert shims as needed between the frame and the wall studs to maintain the correct alignment. Pay particular attention to the hinge side of the door, as this is where alignment is most critical.

5. Once the frame is properly aligned, secure it to the wall studs with long screws, driving them through the shims.

6. Test the door to ensure it opens and closes smoothly and seals tightly against the weatherstripping.

7. Reinstall the interior trim, concealing the shims and screws.

Re-shimming a door frame can be a challenging task, especially for beginners. If you're not comfortable with carpentry work, it's best to leave this to a professional. However, if you're willing to tackle it yourself, take your time, be patient, and double-check your work at each step. The result will be a door that closes properly, seals tightly, and keeps those stubborn drafts at bay.

Sometimes, despite your best efforts with caulking, weatherstripping, and door sweeps, stubborn drafts persist. These situations often point to underlying issues with the door's alignment or the threshold itself. These advanced techniques, while not always necessary, can provide the final adjustments needed for a truly draft-free entryway. It's important to emphasize that these steps are optional and require a bit more skill and patience. If you're uncomfortable with these types of repairs, it's always best to consult a professional.

Adjusting the threshold or re-shimming the door frame might feel like the final boss in the DIY door sealing game. But once these techniques are mastered or appropriately addressed, the next step is crucial: confirming your success and ensuring that your efforts provide long-lasting results. Let's delve into how to test your work and maintain your now draft-free doors.

Testing and Maintenance: Ensuring a Draft-Free Home

After meticulously caulking, weatherstripping, and adjusting your doors, the moment of truth arrives: testing for lingering drafts. This crucial step determines the effectiveness of your efforts and identifies any spots that require further attention. Moreover, consistent maintenance is vital to preserving your door's energy efficiency for years to come.

Methods for Draft Detection

Detecting remaining drafts doesn't require specialized equipment. Simple, readily available methods can pinpoint even the smallest air leaks.

The Hand Test

This is perhaps the easiest and most intuitive method.

On a slightly breezy day, close the door and slowly run your hand along the perimeter of the door frame, paying close attention to the areas where you previously identified drafts. A noticeable temperature change or a subtle breeze against your skin indicates an air leak.

Don't forget to check the threshold area and the bottom of the door as well.

The Incense Test

For a more visual approach, the incense test is highly effective.

Light an incense stick and slowly move it along the door frame, similar to the hand test.

Watch the smoke carefully. If the smoke wavers or is drawn inwards, it indicates a draft pulling air through that specific point. This method is particularly useful for locating very small leaks that might be missed with the hand test.

Maintenance: The Key to Long-Term Energy Efficiency

Sealing drafts isn't a one-time fix. Regular maintenance ensures that your efforts continue to pay off in terms of energy savings and home comfort.

Weatherstripping Care

Weatherstripping is a sacrificial barrier, taking the brunt of weather and wear.

Inspect weatherstripping at least twice a year, ideally during the spring and fall. Look for signs of cracking, tearing, or detachment.

Damaged weatherstripping should be replaced promptly to maintain a tight seal. Clean weatherstripping regularly with a damp cloth to remove dirt and debris, which can degrade the material over time. For certain types of weatherstripping, applying a silicone-based lubricant can help keep it pliable and prevent it from sticking.

Caulk Inspection and Repair

Caulk, especially exterior caulk, is prone to cracking and shrinking due to temperature fluctuations and exposure to the elements.

Inspect caulked areas annually for any signs of damage. Cracks or gaps in the caulk allow air and moisture to penetrate, undermining your sealing efforts.

Remove damaged caulk carefully with a utility knife and reapply a fresh bead of caulk, following the same techniques you used initially. Ensure the surface is clean and dry before applying new caulk for optimal adhesion.

By consistently testing for drafts and diligently maintaining your door seals, you can ensure a comfortable, energy-efficient home for years to come.

When to Call in the Pros: Recognizing Limits of DIY

DIY projects offer a sense of accomplishment and can save significant money. However, knowing when to step back and enlist professional help is crucial, especially when dealing with door sealing. Attempting to fix complex problems without the necessary expertise can lead to further damage and higher costs in the long run.

Structural Damage: A Red Flag

Structural problems are a primary indicator that it's time to call a professional. These issues often extend beyond simple air leaks and require specialized knowledge and tools to address correctly.

Rot and Wood Decay

If you notice soft, crumbling wood around the door frame or threshold, it's likely due to rot or decay. This is often caused by prolonged exposure to moisture and can compromise the integrity of the entire door assembly. Replacing rotted wood and ensuring proper weatherproofing requires carpentry skills and may involve removing and reinstalling the door frame.

Foundation Issues

Cracks in the drywall near the door frame, doors that stick or are difficult to close, or visibly uneven door frames can signal foundation settlement. These issues affect the entire structure and require professional assessment and repair. Ignoring foundation problems can lead to more severe structural damage and make even the best door sealing efforts futile.

Warped or Damaged Door Frames

A severely warped or damaged door frame prevents a proper seal, no matter how much caulk or weatherstripping you apply. While minor warping can sometimes be addressed, significant damage typically necessitates frame replacement, a task best left to experienced carpenters.

When DIY Efforts Fall Short

Even without obvious structural damage, there are situations where DIY door sealing might prove insufficient. These often involve more nuanced problems that require a trained eye to diagnose and correct.

Persistent Drafts Despite Sealing

If you've meticulously caulked, weatherstripped, and installed a door sweep, yet drafts persist, the underlying issue might be more complex than initially anticipated. Hidden gaps, improper installation of materials, or subtle alignment problems could be to blame. A professional can conduct a thorough inspection and identify the source of the drafts.

Recurring Issues

If you find yourself repeatedly repairing the same areas of your door frame or weatherstripping, it's a sign that the root cause of the problem isn't being addressed. This could be due to improper door alignment, water damage, or other underlying issues that require a more comprehensive solution than DIY can provide.

Complex Door Configurations

Some doors, particularly those with intricate designs, sidelights, or transoms, can be challenging to seal effectively. The irregular shapes and multiple joints create more opportunities for air leaks, often requiring specialized sealing techniques and materials best handled by professionals.

The Value of Professional Expertise

While DIY door sealing can be effective for minor drafts, it's important to recognize the limits of your own skills and knowledge. A professional contractor brings years of experience, specialized tools, and a deep understanding of building science to the table. Investing in professional door sealing can save you time, money, and frustration in the long run, ensuring a comfortable and energy-efficient home.
