Window Preparation
Clean and Store Window Screens
- Mix a cleaning solution (2 gallons water + 1 tbsp dish soap). (Pro-Tip: use a t-bar scrubber for a deep clean)
- Release the latches and remove screens from inside.
- Hose down, squeegee and wipe both sides, and rinse.
- Tap to remove residue, then air-dry.
- Store screens upright or flat in a dry space.

Check Seals and Weatherstripping
Inspect weatherstripping and exterior sealant for cracks or damage and replace as needed. Make sure windows and doors close and lock properly—if not, they may need adjustment.
Reduce Window Condensation
Condensation is common in cooler months and usually indicates excess indoor humidity, not window failure. Lowering humidity levels will help minimize moisture.
Patio Door Preparation
- Remove and clean patio door screens using the same process as window screens.
- Vacuum door tracks to clear dirt, stones, and sand that can affect operation and sealing.
- Replace any damaged weatherstripping.
