How to Fix Drafty Windows and Condensation in Leesburg VA Winters

Why Windows Start Drafting And Fogging In Cold Weather

Cold weather has a way of exposing every thin seal, worn latch, and tired pane in the house. You feel it as a chill near the glass, see moisture on the room side of the window, or notice a cloudy film between the panes that never wipes away.

Drafts usually point to air leaks, failed weatherstripping, loose sash components, or gaps where the frame has shifted over time. The glass may look intact, but the system around it may no longer be doing its job.

An experienced window replacement company can confirm the cause with a quick inspection.

How To Tell Drafts From Condensation Problems

Not every problem calls for the same fix, and that matters if you want to spend money wisely. Homeowners often try to solve everything with caulk or spray foam, then wonder why the glass still sweats on cold mornings.

Signs You Are Better Off Replacing The Window

Choosing A Path That Fits The Window And The Home
