When summer hits, we all look forward to opening the windows and letting in fresh air and sunshine. But before you kick back and enjoy the season, it’s smart to give your windows a little care and attention. Well-maintained windows can help keep your home cool, comfortable, and energy-efficient while preventing unexpected headaches down the road. At Renewal by Andersen, we know how local weather can test even the best windows. That’s why we’ve put together this detailed window maintenance checklist for summer to help you keep your windows in top shape all season long.
Why Summer Window Maintenance Matters
Windows aren’t just for enjoying views; they play a huge role in your home’s insulation and overall comfort. Over time, dirt, pollen, moisture and daily use can affect their performance. A little routine maintenance each summer can:
- Improve energy efficiency
- Extend your windows’ lifespan
- Prevent costly damage
- Boost your home’s curb appeal
- Keep your family comfortable and safe
Here are the key steps every Wisconsin homeowner should take:
Inspect Frames, Sills, and Trim
Walk inside and outside your home to check each window. Look for:
- Peeling paint or cracked caulk
- Soft spots or signs of wood rot
- Water stains or mold
Wisconsin’s heavy snow and spring rains can weaken window frames over time. To keep moisture out and protect your windows, touch up peeling paint, reseal caulk, and repair damaged areas.
Clean the Glass — The Right Way
Clean windows look better and maximize natural light and fresh airflow. Use a gentle glass cleaner (or a mix of vinegar and water) with a microfiber cloth. Don’t forget the corners and edges where pollen and dust hide!
Pro tip: Avoid harsh chemicals or abrasive scrubbers — they can damage glass coatings.
Open, Close, and Lubricate Moving Parts
Windows should glide or crank open smoothly. If you feel resistance or hear squeaks:
- Clear out dirt, debris, or bugs from tracks and hinges
- Wipe down tracks with a damp cloth
- Apply a silicone-based lubricant (not oil-based) to moving parts
This simple step keeps your windows easy to operate all season.
Inspect Weatherstripping and Seals
Proper seals keep your cooled indoor air from escaping, saving money on energy bills. Check the weatherstripping around each window:
- Look for cracks, gaps, or pieces peeling away
- Gently tug to see if it’s still secure
- Replace any worn or missing strips
Renewing weatherstripping is an inexpensive fix that can make a big difference.
Check Locks and Safety Latches
Wisconsin homeowners often travel in summer. To help keep your home safe while you’re away, make sure all windows lock securely. If locks are loose or misaligned, tighten screws or replace hardware as needed.
Repair and Clean Screens
Nothing ruins a summer breeze faster than a swarm of mosquitoes! Inspect screens for tears or holes. If you spot damage:
- Patch small holes with a screen repair kit
- Replace badly damaged screens
- Gently wash screens with soapy water and rinse thoroughly
Reinstall clean, sturdy screens to enjoy fresh air without pests sneaking in.
Know When to Call the Pros
Some window problems need more than DIY care. If you notice:
- Foggy glass (moisture between panes)
- Warped or sagging frames
- Drafts you can’t seal
- Difficulty opening or closing windows
…it may be time for a professional inspection or replacement. Wisconsin’s weather demands durable, energy-efficient windows, and Renewal by Andersen’s experts are always ready to help you find the right solution.
