Summer Window Maintenance Checklist

Wisconsin summers bring warm breezes, sunshine, and the perfect chance to check in on your windows. Keeping your windows in great condition helps improve energy efficiency, curb appeal, and your home’s comfort all season long. This simple summer window maintenance checklist will help you keep your windows working like new! 

Inspect Window Frames & Sills 

Look for signs of wear, such as peeling paint, cracks or moisture damage. Wisconsin’s freeze-thaw cycles can take a toll on wood and older frames. Touch up paint or sealant as needed to protect your windows from summer humidity and rain. 

Clean the Glass Thoroughly

Use a soft cloth and a gentle glass cleaner to remove pollen, dirt, and fingerprints from both the interior and exterior panes. Clean windows maximize natural light and fresh air flow throughout your home. 

Check and Lubricate Moving Parts

Open and close each window to ensure smooth operation. Clean out any debris from tracks and hinges, then apply a silicone-based lubricant to help keep everything moving easily. 

Inspect Weatherstripping 

Summer storms can push moisture inside if seals are damaged. Check the weatherstripping for cracks or gaps and replace worn pieces to keep cool air in and humidity out. 

Test locks and Safety Latches

Next on our summer window maintenance checklist, make sure all locks and safety latches work properly. Secure windows, deter break-ins, and provide peace of mind while you enjoy the summer sun. 

Consider Screens & Insect Protection 

Inspect window screens for holes or tears. Clean screens gently with soapy water and a soft brush. Replace damaged screens to keep bugs outside where they belong.
