How Do I Stop Drafty Windows in Winter?

Drafty windows in an Avon home aren’t just uncomfortable — they drive up energy bills every single month.

Identifying whether you need repairs or full replacement windows in Avon is the first step.

Ways to Stop Cold Air from Coming Through Your Windows

Check the weatherstripping: Worn or compressed weatherstripping is one of the most common causes of drafts. Quality windows feature triple weatherstripping at every contact point.
Inspect the caulk line: Gaps between frame and wall let cold air in. Re-caulking is a short-term fix; replacement is the long-term solution.
Look for condensation patterns: Frost forming on the interior glass often signals a failed seal that requires replacement, not just weatherstripping.
Consider full replacement: Windows more than 20 years old usually need replacing, not patching. Our 0.1 CFM-rated frames eliminate infiltration at every point.
Don’t rely on plastic sheeting: Temporary film delivers minimal benefit compared to properly installed Energy Star 7.0 certified windows.

Your Next Step to Stop Drafts in Avon

Top Recommendation: Full window replacement for Avon homes with windows over 20 years old — weatherstripping alone can’t compensate for degraded frames and seals.

Best for Budget: Re-caulk and re-weatherstrip newer windows first; schedule replacement for the worst-performing openings.

Best for Immediate Results: Our 0.1 CFM-rated fusion-welded frames stop infiltration at every point the same day they’re installed.

Our window contractors in Avon can assess your home and find the right fix.
