STRIVING TO BE YOUR TRUSTED PROJECT PARTNER

Keep drafts and moisture out and your energy bills down with proper weather stripping and sealing services.

Weather stripping and caulking aren’t glamorous — but they’re crucial for comfort and cost-saving. We focus on the trouble spots: drafty windows, leaky bathroom corners, cracking exterior joints. We remove failing caulking and apply clean, effective seals that protect your space from water, pests, and energy loss.

Before winter or after a renovation, this is the finishing touch that makes your home feel truly complete.

Looking forward to starting your next project!

🏠Seasonal Weatherstripping Services Checklist🏠

Seal in comfort and savings year-round with simple weatherstripping maintenance tips.


🌷 Spring – Repair and Refresh

⬜ Inspect weatherstripping around all exterior doors for signs of wear, cracking, or peeling


⬜ Check window seals and replace damaged or missing strips

⬜ Clean surfaces where weatherstripping is applied — dirt and buildup can weaken the bond


⬜ Re-seal attic or crawl space access doors for better air control


⬜ Test sliding doors for proper seal and function


💡Did You Know? Even a ⅛-inch gap around a door can let in as much air as leaving a small window open all day — sealing it can cut energy costs significantly.


☀️ Summer – Block the Heat


⬜ Check for drafts near windows and doors during the hottest part of the day


⬜ Replace worn-out stripping on garage entry doors to keep cooled air inside


⬜ Install or upgrade weatherstripping on attic hatches to reduce heat transfer

⬜ Ensure sliding windows and patio doors close tightly with no air gaps

⬜ Use adhesive-backed foam or vinyl strips to reinforce high-traffic entry points


💡Did You Know? Weatherstripping doesn’t just keep cold out — it also keeps cool air in during the summer, reducing your A/C use.


🍂 Fall – Prep for Cold Weather


⬜ Inspect and replace worn weatherstripping before the first frost hits


⬜ Add door sweeps to the bottom of exterior doors to block cold air

⬜ Recheck window seals, especially in older frames or wooden sashes

⬜ Upgrade to more durable materials (like silicone or rubber) for lasting protection

⬜ Seal utility openings (pipes, dryer vents, etc.) with weather-resistant caulk or gaskets


💡Did You Know? Proper weatherstripping can reduce your heating bills by up to 15% — and it usually pays for itself within the first season.


❄️ Winter – Comfort & Energy Savings

⬜ Monitor doors and windows for cold spots or drafts — even new seals can loosen


⬜ Reapply or press down adhesive weatherstripping if edges lift due to cold air

⬜ Use door snakes or temporary draft stoppers as extra insulation where needed

⬜ Keep garage and basement doors tightly sealed to prevent cold air from spreading

⬜ Plan weatherstripping upgrades in quiet winter months before spring rushes


💡Did You Know? Drafts are one of the most common causes of cold rooms — and one of the easiest fixes with simple weatherstripping services.
