Silicone resealing addresses the exterior joint between the window frame and the siding or trim. Weatherstripping addresses the seal between the sash and the frame when the window opens. Both can fail. We check the exterior caulk joint first, then the sash seal.
Yes. Water that gets behind the exterior caulk joint works its way into the rough opening and can rot the jack studs, sill plate, and interior drywall. The exterior seal is the first and most important line of defense.
Quality 100-percent silicone sealant on a properly prepped surface lasts 10 to 20 years. Paintable acrylic caulk lasts 5 to 10 years. We use the right product for each window type and location.

"Jacob is the best ever. He made my dream come true by installing my catwalk for my cat to the ceiling when no other contractor could handle the job. I was extremely impressed by his expertise and he is definitely someone you can trust. It's hard to come by professionals who are also kind and Jacob is just stellar. I even paid him extra because he did such an amazing job."
