Measure and Cut the New SealMeasure each side exactly, adding a little overlap(≈ 1/4 inch)for compression. Cut the replacement seal to size using a sharp energy knife. Use Adhesive (If Required) For foam tape or V‑strip seals, use a thin bead of exterior‑grade sealant along the frame's edge. Follow producer directions regarding cure time. Set Up the New Seal Starting at one corner, press the seal securely into place, ensuringeven call. For compression seals, close the window slightly totest the fit before totally protecting. Test for Air and Water Tightness Close the window and run a hand‑feel test along the edges. Use a spray bottle with water to look for leakages; any seepage shows a poorseal.
