Drafts at doors and windows: repair, seal or replace?
A draft near a window or door does not prove that the unit needs replacing. The air path may be at a moving joint, fixed trim or another nearby gap. Identify the location and any moisture or damage before deciding what work to request.
Observe the problem safely
Record the location, weather conditions, whether the window or door closes properly, and any water staining or damaged material. ENERGY STAR describes visual checks for gaps; avoid disturbing suspect insulation, dismantling frames or blocking ventilation to find a leak. A professional assessment can help where the path is unclear.
Match the repair to the joint
Weatherstripping is commonly used where a door or window moves. Caulk is used at suitable stationary gaps. A damaged frame, failed installation or moisture intrusion may need a qualified repair rather than another layer of sealant. Ask how the proposed work handles ventilation, water and relevant safety issues.
Ask why replacement is necessary
Compare a targeted repair and replacement on the same problem: exact location, materials, installation, finish restoration, safety checks and how completion will be verified. A replacement quote should explain why repair is insufficient. Verify local incentives with the program itself and do not treat a generic savings figure as a prediction for this house.
