Spring cleaning season is here, and so often, homeowners’ spring cleaning checklists don’t include windows and doors. That’s a missed opportunity. A thorough inspection and cleaning of your windows and doors can improve energy efficiency, catch small problems before they become expensive ones, and give your home’s interior and exterior a noticeably fresh look.
Use this checklist to work through every window and door in your home this spring!
Windows: Interior Checklist
☐ Clean the glass. Use a streak-free glass cleaner and a microfiber cloth for the best results. Avoid paper towels, which can leave lint behind. Clean both panes thoroughly and work in natural light so you don’t miss spots.
☐ Wipe down the frames and sills. Dust, dirt, and moisture can accumulate on window frames and sills over winter. Wipe them down with a damp cloth and mild soap. For wood frames, check for any signs of moisture damage or peeling paint.
☐ Vacuum the tracks. Window tracks collect debris, dead insects, and dust year-round. Use a vacuum with a narrow attachment to clean them out, then wipe with a damp cloth.
☐ Lubricate the hardware. If your windows are sticking or hard to open, the hardware may just need a little lubrication. Use a silicone-based lubricant on the tracks and moving parts (avoid WD-40, which can attract dust over time).
☐ Test the locks. Open and close each window and test the lock. It should open smoothly and hold firmly. A window that won’t lock properly is a security concern.
☐ Check the weatherstripping. Run your hand along the edges of closed windows. Feel any air movement? That’s a sign the weatherstripping is worn and needs to be replaced.
☐ Look for condensation between panes. Foggy or cloudy glass between panes indicates a failed seal. This is not a DIY fix; it typically means the window needs to be replaced.
Windows: Exterior Checklist
☐ Inspect the caulking. Walk around the outside of your home and check the caulk around every window frame. Look for cracks, gaps, or areas where the caulk has pulled away from the surface. Failed caulking allows water intrusion and air leaks.
☐ Check for visible frame damage. Look closely at the frames for cracks, warping, rot (on wood), or fading. Minor cosmetic issues are one thing, but structural damage to the frame can compromise the window’s performance.
☐ Clean exterior glass and frames. A garden hose and soft brush can handle most exterior window cleaning.
☐ Examine the flashing. The metal flashing around your windows directs water away from the frame. Make sure it’s intact, properly sealed, and not pulling away from the wall.
Doors: Interior Checklist
☐ Clean the door surface, frame, and hardware. Wipe down the door with a gentle cleaner, making sure it is safe for the door material (wood, fiberglass, or steel). Polish hardware if needed. Don’t forget the tops and bottoms of doors, which are easy to miss.
☐ Test the door swing. Open and close each door fully. It should swing freely without scraping the floor or catching on the frame. If it’s sticking, the hinges may need tightening, or the door may have shifted.
☐ Check the weatherstripping. Door weatherstripping takes a beating every winter. Check the strips along the sides and top of the door for compression, tearing, or gaps. Replace any sections that are worn.
☐ Inspect the door sweep. The door sweep at the bottom of exterior doors is your first line of defense against drafts, moisture, and pests. If you can see daylight under the door or feel a draft, the sweep needs to be replaced.
☐ Test all locks and deadbolts. Every lock should engage smoothly and hold securely. If a deadbolt is hard to turn or a latch doesn’t catch, address it now. Don’t wait until it fails completely.
☐ Lubricate hinges and locks. A little lubrication goes a long way. Use a dry or silicone-based lubricant on door hinges and lock mechanisms to keep everything operating smoothly.
Doors: Exterior Checklist
☐ Inspect the door frame and threshold. Look for cracks, rot, or damage to the door frame and threshold. Water damage around the base of exterior doors is common and can spread quickly if ignored.
☐ Check the caulking. Just like windows, the caulk around your door frame should be intact with no cracks or gaps. Re-caulk any areas where the seal has failed.
☐ Examine patio and sliding door tracks. Patio and sliding door tracks accumulate dirt and debris that can interfere with smooth operation. Clean them out and lubricate the rollers.
☐ Look for glass seal failure in door glass panels. If your entry door or patio door has glass panels, check for the same fogging or condensation you’d look for in windows. A failed glass seal in a door panel needs professional attention.
When Cleaning Isn’t Enough
Sometimes spring cleaning reveals problems that go beyond a wipe-down or a tube of caulk. If you’re finding multiple signs of wear — failed seals, damaged frames, persistent drafts, or locks that won’t function properly — it may be time to consider replacement rather than repair.
