What’s Happening

Drafty windows are almost always a sign that the weatherstripping, glazing seals, or the frame itself has failed – and your heating and cooling system is working overtime to compensate. This is a fixable problem, not a reason to panic, but it does not get better on its own.

When a window seal breaks down, conditioned air escapes around the edges or through the glass unit itself. Your HVAC runs longer cycles to hold the temperature you’ve set, and that extra runtime shows up on your energy bill. The drafts you’re feeling are the same gaps your heating and cooling dollars are escaping through. Most homeowners notice the symptom for weeks before they connect it to the bill – but once you make that connection, it’s worth getting someone out to take a look before the next billing cycle.

Why It Happens

Failed Weatherstripping

Weatherstripping is the soft seal that runs along the sash and frame wherever the window closes. Over time it compresses, tears, or simply falls away from the channel it sits in. You can usually spot this one yourself: close the window on a piece of paper and try to pull the paper out. If it slides out without resistance, the seal isn’t doing its job. You may also see daylight around the edges when you look closely at a closed window on a sunny day.

Insulated Glass Unit (IGU) Failure

Most modern windows have two or three panes of glass with a sealed air or gas space between them. When that seal breaks, the insulating layer is gone – and you’re left with what is essentially single-pane performance even though the window still looks intact. The sign here is fogging, condensation, or a cloudy haze between the panes that won’t wipe away. If you see that, the IGU has failed and the cold transfer you’re feeling through the glass is directly connected to it.

Frame Warping or Settlement

Wood and composite frames can warp over time, especially in climates with significant humidity swings. A warped frame no longer sits flush with the rough opening, and the gap that opens up is a direct air path into your home. If your window has become harder to open or close in the last year or two, or if it no longer latches smoothly, that’s a frame problem worth having inspected. You might also notice the draft is worst at the corners, not the middle of the sash.

Worn or Missing Interior Caulking

The bead of caulk where the window frame meets the interior drywall is the last line of defense against air moving through the wall cavity. It cracks, shrinks, and pulls away from the surface as the house moves seasonally. This one is visible without any tools: look at the line where the trim meets the wall around any window that feels drafty. Gaps, cracks, or sections where the caulk has clearly separated are letting more air through than most people expect.

What to Do Right Now

• Hold your hand near the frame edges and corners with the window closed. Don’t use a candle near the glass or near any combustion appliance – just use your palm. Note which windows feel cold and exactly where on the frame the air movement is strongest. That information is useful for whoever comes out to look.
• Check the weatherstripping visually. Open the window and look at the foam or rubber seal along the sash. If it’s flat, torn, or missing in sections, photograph it before you call.
• Look between the panes, not at them. If there’s fogging, streaking, or condensation trapped inside the glass unit, photograph that too. It helps a technician confirm IGU failure before they arrive.
• Don’t seal over failed weatherstripping with tape or spray foam as a permanent fix. Tape can damage the finish on a sash, and spray foam applied to the wrong area can interfere with the window’s ability to open safely for egress. A short-term draft block with a foam backer rod is fine – anything adhesive or expanding on the sash itself is not.
• Note when the draft is worst. Is it only on windy days? Always on one side of the house? Worse in the morning? That pattern tells a technician whether you’re looking at a seal failure, a frame gap, or a pressure differential from your HVAC system.

How We Fix It

When your local Hale Windows & Doors team arrives, the first thing they do is a systematic inspection – not a sales presentation. They check the weatherstripping, examine the IGU for seal failure, look at the frame for warping or gap at the rough opening, and assess the caulking line inside and out. That inspection drives the diagnosis, and the diagnosis drives the written price you get before any work starts. No guessing, no “we’ll figure it out as we go.”

For most drafty windows, the fix falls under Window Repair: replacing weatherstripping, resealing the frame, or swapping a failed IGU while keeping the existing frame. Where the frame or the window itself has reached the end of its useful life, Window Replacement is the right answer, and your team works from eight product lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – to match the right window to your home rather than defaulting to whatever’s easiest to install. Either path is covered by the 365-Day Done Right Promise: if it’s not right, we make it right. And every repair carries a written guarantee – if the repair fails, the second visit is free.
