RV window sealing near Sammamish isn’t something you want to take lightly. Over time, weather, vibration, and exposure wear down the original sealant, leaving your RV vulnerable to leaks. When water gets inside, it can lead to mold, rot, and costly repairs. That’s why it’s important to reseal windows the right way—with professional tools, experience, and materials.

Step 1: We Remove All Old Sealant

We start by removing the old sealant completely. This step is more detailed than it sounds. We carefully cut away the existing caulk or butyl tape, taking care not to damage the RV’s frame or glass. This ensures the new seal has a clean, solid surface to bond to. Any leftover sealant or dirt can prevent a good seal and cause leaks later on.

Step 2: We Clean and Prep the Area

Once the old material is gone, we clean the entire area with a specialized solvent that removes oils, grime, and any remaining adhesive. We inspect for any signs of moisture or frame damage while we work. Clean prep is key to making sure the new seal sticks properly and lasts.

Step 3: We Apply High-Quality Sealant

Now it’s time for the seal. We don’t use cheap hardware store caulk. We use professional-grade sealants designed for RV use—flexible, UV-resistant, and long-lasting. Depending on the window type, we apply either a new bead of caulk or install fresh butyl tape before carefully resetting the window. Then we finish the edges with a smooth, even seal to protect against the elements.
