How to Inspect Windows & Doors Like a Pro: A Homeowner’s Guide
Your windows and doors do more than provide a view and a way in or out—they play a big role in your home's energy efficiency, security, and overall comfort. That’s why it's a good idea to inspect them at least once or twice a year, especially in spring and fall.
Start with a Visual Check
Take a walk around your home—inside and out—and look for signs of wear and tear. Focus on:
Cracks in the glass or frame
Peeling paint or wood rot (especially in older wooden frames)
Rust or corrosion on metal components
Visible gaps between the frame and wall
If anything looks damaged, it could be a sign that moisture or air is sneaking in where it shouldn't.
Check for Drafts
One of the easiest ways to test for air leaks is with a simple candle or incense stick:
Light it and slowly move it around the edges of windows and doors.
If the flame flickers or smoke wavers, there's likely a draft.
Drafts can drive up your energy bills and make your home less comfortable—especially in extreme temperatures.
Inspect the Seals & Weatherstripping
Weatherstripping around doors and windows helps block air and moisture. Over time, it can crack, flatten, or peel away.
Look for:
Loose or missing pieces
Cracked rubber or foam
Sticky or brittle texture
If your weatherstripping has seen better days, replacing it is a quick and inexpensive fix that can make a big difference.
Test the Hardware
Make sure all locks, handles, and hinges are functioning properly:
Open and close each window and door to check for smooth operation.
Lubricate squeaky hinges with a silicone-based spray.
Tighten any loose screws and test the locks for proper security.
Poorly functioning hardware can be both a safety risk and a sign of structural settling or damage.
Look for Moisture or Condensation
Condensation between glass panes could mean a broken seal in double- or triple-pane windows. Also check for:
Water stains on the walls or floors near doors or windows
Soft or warped wood around the frames
Persistent moisture issues can lead to mold and structural damage, so it’s best to catch them early.
Evaluate Energy Efficiency
If your windows and doors are older, they may not be as energy-efficient as newer models. Look for:
Single-pane glass
Aluminum frames with no thermal break
Outdated or missing insulation
Replacing older windows and doors can improve your home’s energy efficiency and boost its resale value.
Final Tip: Create a Seasonal Checklist
To keep your home in top shape, add window and door inspection to your seasonal home maintenance checklist. A quick inspection in the spring and fall will help you spot small issues before they become costly problems.
Thinking of selling? Buyers love homes that are well-maintained and energy-efficient. A quick window and door check-up now can help you avoid surprises during an inspection later.
