Step-by-Step Guide to Sealing Sash Windows

Here is a step-by-step guide to sealing sash windows:

  1. Cleaning the windows and frames: Start by thoroughly cleaning the windows and frames using a mild detergent and water solution. This will help remove dirt, grime, and any old sealant that may be present.
  2. Repairing any damaged areas: Inspect the windows for any damaged areas such as cracks, rot, or gaps. Repair these areas using wood filler or epoxy resin to ensure a smooth surface for sealing.
  3. Applying caulk to seal gaps and cracks: Use a high-quality silicone or acrylic caulk to seal any gaps or cracks around the window frame. Apply the caulk in a continuous bead along the edges where the frame meets the wall, ensuring a tight seal to prevent drafts.
  4. Installing or replacing weatherstripping: Weatherstripping helps create a tight seal between the sash and frame, preventing air leaks. Measure the dimensions of your window sash and purchase weatherstripping that fits snugly. Install it along the edges of the sash where it meets the frame, ensuring a proper seal.
