Old, cracked, or missing caulking around your windows can lead to air leaks, moisture damage, and higher energy bills. But how do you know when it’s time to re-caulk your windows? In this guide, we’ll show you the key signs to watch for and explain how professional window caulking services can help protect your home.
How to Know It’s Time to Re-Caulk Windows and Stop Air Leaks
Window caulking isn’t meant to last forever. Over time, it can dry out, shrink, crack, or peel away. If this happens, your windows lose their seal, allowing outside air and moisture to sneak in. Here are the most common signs it’s time to re-caulk:
- Drafts or Air Leaks: Feeling a breeze near your windows? That’s a sign the seal is broken.
- Visible Gaps or Cracks: If the caulking is pulling away from the frame or wall, it’s time to replace it.
- Moisture Around Frames: Wet spots, condensation, or mildew near your windows could mean water is getting in.
- Peeling or Crumbling Caulk: Old caulk that’s dry, flaking, or falling apart won’t protect your home.
- Rising Energy Bills: Poor seals make your HVAC system work harder, increasing heating and cooling costs.
- Pest Entry Points: Tiny cracks are perfect spots for bugs to sneak into your home.
- Loose Window Panes: Caulking also helps secure the glass in place—if it’s failing, panes may shift or rattle.
When to Re-Caulk Windows: Protect Your Home from Moisture & Drafts
If you’ve noticed any of these signs, don’t wait. Re-caulking your windows helps:
- Prevent moisture damage to your drywall, sills, and window frames.
- Block air leaks that reduce your home’s energy efficiency.
- Stop mold growth by keeping out excess humidity.
- Avoid costly repairs like rotting wood, rust, or peeling paint.
How Often Should You Re-Caulk Windows?
On average, caulking should be replaced every 5–10 years. But in Ontario’s climate—where we get harsh winters and humid summers—caulking may break down faster. If you live in Oshawa, Ajax, Pickering, or Toronto, regular checks are smart. If you’re unsure, you can always request a home window caulking estimate from local window re-caulking experts.
What’s the Best Exterior Window Caulk?
Look for high-quality, weatherproof caulk made for exterior use. Silicone or polyurethane caulk is great for resisting moisture, sun damage, and temperature changes. For long-lasting results, it’s best to hire a caulking contractor for windows with experience in our local weather conditions.
