How to Repair a Leaky Window in a Sailboat

Many windows suffer from leaks from time to time. Because of their constant exposure to water as well as harsh elements such as rain and wind, sailboat windows are particularly vulnerable to leaking. Often, the problem with a sailboat window is that the sealant that connects the window to the boat's frame no longer works properly. This is easy to fix by removing the window, scraping off the sealant and resealing the window.

• 1

  Remove any screws that hold the window in place using a screwdriver. Gently remove the window by pushing from inside the boat. If possible, have a friend stand on the outside of the boat and help you remove the window. Do not push the window to a place where it will shatter and cause injuries, such as a dock or the water.

• 2

  Peel away the sealant on the window using a sharp knife. Make a diagonal cut through the corners of the sealant and peel the sealant from the window sill. You should be able to pull the sealant easily.

• 3

  Clean the window and frame using solvent. Follow the directions on the solvent. Typically you must dip a cloth in the solvent and run the solvent along the window and frame. Clean again with rubbing alcohol and finally with glass cleaner. Allow the window and frame to dry for two to three hours.

• 4

  Apply the silicone to the window to create a new seal. You may use a caulking gun, but generally for a small job, applying from the tube is fine. Run your finger along the bead of silicone to smooth it out.

• 5

  Re-inset the window, or insert a replacement window. Add another seal of silicone, rubbing your finger across the place where the window and the frame meet. Allow this to dry for two to three days before subjecting it to the elements.
