How to Fix Drafty Windows in Older Bethesda Homes

If you live in an older Bethesda home, you already know that window drafts can make a room feel colder than the thermostat suggests. Drafts are easy to ignore until they become expensive.

The good news is that many drafty windows can be improved without tearing out the whole unit. An experienced window replacement Bethesda MD company can confirm the cause with a quick inspection.

Why Drafty Windows Are So Common In Older Bethesda Homes

Replacement starts to make more sense once the frame is damaged, the operation is poor, or the same unit keeps failing after repairs. That is even more true if you are also seeing condensation between panes, wood decay, or repeated hardware failure.

If the home falls under historic review, the choice between repair and replacement may depend on design rules as much as on performance. In those cases, preserving the existing opening or choosing a historically compatible product may be part of the process.

What Actually Helps Stop Drafts
