How To Fix A Drafty Window

Is there anything more annoying than feeling a cold breeze sneaking in through a window when you’re trying to stay cozy? Drafty windows aren't just uncomfortable; they can also send your energy bills soaring. But don't worry, you don't have to resign yourself to a chilly home or break the bank on expensive replacements. With a few simple steps, you can often fix those pesky drafts yourself. Let’s dive in and discover how to fix a drafty window and reclaim your comfort!

Identifying the Source of the Draft

Before you start grabbing caulk and weatherstripping, you need to pinpoint exactly where the draft is coming from. This might seem obvious, but sometimes the source is more subtle than you think. One of the first methods you can use to identify a draft is to simply use your hand. You can also use asmoke stick or a litcandle near the window frame. If the smoke or flame flickers, you've found a leak! Move around the entire window, paying close attention to:

1. The edges of the window frame
1. The meeting points where the window sash closes
1. Around the trim where the window frame meets the wall

Don't forget to check the glass itself! While less common, a crack in the glass or a failed window seal can also cause drafts. You might also want to check for: Visible gaps, cracks, or damage to the caulk or weatherstripping around the window. Condensation between the panes of glass, which indicates a broken seal. This may require more extensive repair, or even window replacement.

Quick and Easy Fixes for Drafty Windows

Once you've identified the culprit, it's time to take action! Here are some easy and affordable solutions to immediately improve your comfort and stop your heat from escaping. There are multiple ways to fix a drafty window. These fixes will save you money on utility bills.

Applying Weatherstripping

Weatherstripping creates a seal between the window sash and the frame, blocking airflow. It comes in various materials, including foam, felt, vinyl, and rubber. Choose the type that best suits your window and the size of the gap. It's a very popular and cheap way to fix a drafty window. It can be purchased at any home improvement store.

Here's how to apply weatherstripping:

1. Clean the surface where you'll be applying the weatherstripping. Remove any dirt, debris, or old adhesive.
1. Measure and cut the weatherstripping to the correct length.
1. Peel off the backing and carefully apply the weatherstripping along the window frame or sash, pressing firmly to ensure a good seal.

Pay special attention to corners and meeting points, as these are common areas for drafts. Different types of weatherstripping are suited for different window types and gap sizes. Some popular options include:

1. Foam tape: Inexpensive and easy to install, but less durable than other options. Best for small gaps.
1. V-seal weatherstripping: Made of plastic or metal, it creates a tight seal when the window is closed. Durable and long-lasting.
1. Felt weatherstripping: Traditional and affordable, but can wear down quickly.

Caulking Gaps and Cracks

Caulk is another essential tool for sealing gaps and cracks around windows. It's especially effective for filling gaps between the window frame and the wall. Caulk is a great method to fix a drafty window that has gaps and cracks.

Here's how to caulk a window:

1. Clean the area you'll be caulking, removing any loose paint, old caulk, or debris.
1. Load a caulk gun with a tube of high-quality exterior-grade caulk.
1. Cut the tip of the caulk tube at a 45-degree angle.
1. Apply a smooth, consistent bead of caulk along the gap or crack.
1. Use a wet finger or a caulk smoothing tool to create a neat and professional finish.

Consider these important tips when applying caulk:

1. Choose a caulk that is paintable if you plan to paint the window frame.
1. Apply caulk on a dry day when the temperature is above freezing.
1. Don't apply caulk too thickly, as it can crack or peel over time.

Window Film: A Temporary Solution

Window film is a thin plastic sheet that adheres to the inside of your window, creating an extra layer of insulation. It's a quick, inexpensive, and temporary solution that can significantly reduce drafts. Window film is a good method for those looking for a very fast fix to a drafty window.

To install window film:

1. Clean the window thoroughly.
1. Measure and cut the film to the size of the window pane.
1. Apply double-sided tape around the window frame.
1. Remove the backing from the tape and carefully apply the film to the tape.
1. Use a hairdryer to shrink the film and remove any wrinkles.

Window film is a great option for renters or anyone who wants a quick and easy fix. It's not as durable as weatherstripping or caulk, but it can make a noticeable difference in your comfort.

Addressing More Complex Window Problems

Sometimes, the simple fixes aren't enough. If you've tried weatherstripping, caulking, and window film and you're still feeling drafts, you may have a more serious problem. Some problems could be related to needing to fix a drafty window.

Inspecting and Repairing Window Putty

Older windows often use putty to seal the glass to the frame. Over time, this putty can dry out, crack, and fall away, creating gaps that let in drafts. Here's how to fix crumbling window putty:

1. Carefully remove the old, loose putty with a putty knife.
1. Apply a thin layer of linseed oil to the exposed wood.
1. Roll out fresh putty into a rope and press it firmly into the gap between the glass and the frame.
1. Smooth the putty with a putty knife, creating a clean, angled finish.
1. Allow the putty to dry completely before painting.

Replacing window putty can be a bit messy, but it's an essential step in restoring older windows and preventing drafts. If you aren't comfortable working with putty, consider hiring a professional.

Checking for Air Leaks Around the Window Frame

Even if the window itself is properly sealed, drafts can still enter your home through gaps around the window frame. To check for these leaks, run your hand along the edges of the frame where it meets the wall. If you feel a draft, you'll need to seal these gaps with caulk or expanding foam. This is another key area to check when trying to fix a drafty window.

To seal air leaks around the window frame:

1. Remove any trim around the window frame.
1. Fill any large gaps with expanding foam. Be careful not to overfill, as the foam will expand and potentially damage the frame.
1. Once the foam is dry, trim off any excess.
1. Caulk the gap between the window frame and the wall.
1. Replace the trim.

When to Consider Window Replacement

If your windows are old, damaged, or poorly insulated, you may need to consider replacing them altogether. Window replacement is a significant investment, but it can dramatically improve your home's energy efficiency and comfort. Here are some signs that it's time to replace your windows:

1. The windows are difficult to open or close.
1. There is condensation between the panes of glass, indicating a broken seal.
1. The window frames are rotted or damaged.
1. You can feel significant drafts even after sealing the windows.
1. Your energy bills are consistently high.

When choosing replacement windows, look for energy-efficient models with a low U-factor and a high Solar Heat Gain Coefficient (SHGC). These ratings indicate how well the window insulates and blocks heat from the sun. Consider Low-E glass and argon gas fills for added insulation.

Case Study: A homeowner in Minnesota replaced their 30-year-old single-pane windows with new, energy-efficient double-pane windows. Their energy bills decreased by 25%, and they reported a significant improvement in their home's comfort level.

Long-Term Benefits of Fixing Drafty Windows

Addressing drafty windows isn't just about immediate comfort; it's also an investment in your home's long-term health and value. The benefits extend far beyond simply feeling warmer in the winter. Fixing a drafty window leads to savings.

Reduced Energy Bills

This is perhaps the most obvious benefit. By sealing air leaks, you prevent heat from escaping in the winter and cool air from escaping in the summer. This reduces the workload on your HVAC system and lowers your energy bills. According to the Department of Energy, sealing air leaks can save homeowners up to 20% on their energy bills.

Increased Home Comfort

Eliminating drafts makes your home more comfortable year-round. You'll no longer have to deal with cold spots near windows or uneven temperatures throughout your home.

Improved Indoor Air Quality

Drafts can bring in dust, pollen, and other allergens, which can worsen allergies and respiratory problems. Sealing windows helps to keep these pollutants out, improving your indoor air quality.

Protection Against Moisture Damage

Drafts can also allow moisture to penetrate your home, leading to mold growth and wood rot. Sealing windows helps to prevent moisture damage and protect your home's structure. Drafts can cause mold and moisture damage if you do not fix a drafty window.

Increased Home Value

Energy-efficient homes are more attractive to buyers. By sealing drafts and making other energy-efficient upgrades, you can increase your home's value and make it more appealing to potential buyers.

Conclusion: Taking Control of Your Home's Comfort

Fixing drafty windows is a worthwhile investment that pays off in comfort, energy savings, and home value. Whether you choose simple DIY solutions or opt for professional window replacement, taking the time to address drafts can make a significant difference in your home's overall performance.
