How to Diagnose Drafts

Start with a practical check - open and close the sash, look for daylight between the sash and frame, and hold a lit stick of incense near suspect joints to watch air paths. An experienced window replacement company can confirm the cause with a quick inspection.

If the draft is coming from the sash fit, new weatherstripping often solves the problem without replacing the entire window. Materials and labor for a single sash job are typically modest, and work can be completed in a few hours per window in most cases.

Restoring Window Seals
