The best way to stop drafty windows in the winter is with energy-efficient window replacement.

Your Fall Window Checklist

Seal check: Look for cracked caulk and worn weatherstripping around each sash this fall. Get a free estimate if gaps return.
Clean tracks: Clear dirt from sills and tracks so sashes close tight.
Fogged glass: Fog between panes signals a failed seal that cleaning cannot fix.
Small surface: Windows cover about 8% of a home’s exterior surface area, per PNNL.
Upgrade payoff: ENERGY STAR certified units can cut heating and cooling bills by up to 13%.

Getting Windows Winter-Ready

Top Recommendation: A free inspection checks seals, tracks, and any fogged glass. Book yours this fall.

Better Than Resealing: Replacing windows with failed seals beats caulking them each winter.

Smart for Fall: Finish these checks before heating season begins.
