How it works

Identify air infiltration points

We run a hand along the window perimeter and sash edges to feel exactly where air is coming in before doing any work.

Seal and weatherstrip

We apply the right seal for each gap type — caulk for fixed joints, weatherstripping for moving parts.

Verify the improvement

We recheck the window after sealing to confirm the drafts are eliminated and the sash still operates smoothly.

We can help

Problems we fix

Gap between the window frame and the rough opening, often hidden behind interior trim
Degraded glazing compound on single-pane wood windows that lets cold air radiate in
Sash channels on double-hung windows where the weatherstripping has compressed flat
Air infiltration at the window stool and apron from missing interior caulk

Weatherproofing Windows — FAQ

Is it worth weatherproofing old windows instead of replacing them?

For structurally sound windows with single-pane glass, weatherproofing can cut drafts significantly at a fraction of replacement cost. We'll be honest about when replacement makes more financial sense.

Can window film really make a difference on cold windows?

Shrink-film kits add a dead-air pocket that noticeably reduces cold radiation from single-pane windows. It's a great seasonal option for older homes.

Will weatherstripping affect how the window opens?

Properly fitted weatherstripping compresses when the sash closes and releases when you open it — it shouldn't make the window stiff if the right type and thickness is used.
