Fixing Drafty Windows and Condensation in Leesburg, VA Winters

How Cold Weather Exposes Weak Windows

When a Leesburg house starts feeling colder near the windows, the problem is usually not the furnace, it is the enclosure around the glass.

A draft can come from several places, including worn weatherstripping, loose sashes, gaps between the frame and trim, or failed caulking on the exterior.

If moisture is on the inside of the room, the house may simply have too much humidity for the cold surface of the glass.

In Leesburg, winter weather makes these problems easier to spot because nights get cold enough to expose weak seals and poor insulation.
