How to Fix Leaking Insulated Windows

Leaking windows is not something a homeowner wants to deal with. Luckily, leaky windows do not take a lot of time to repair and can be of low cost. If water gets into your home through a leaky window you could be faced with thousands of dollars in repairs.

Items Needed

• Eye Protection


• Gloves


• Insulation


• Various Tools

1. Inspect your windows to get an exact idea of the leaking issues. Decide whether or not the window is actually leaking air or water. Your repairs will be based on this knowledge.

2. Repair air leaking windows with a new weatherstrip. A weatherstrip can prevent air from leaking into the home. Leaking air can result in hundreds of dollars in extra utility costs so adding a weatherstrip helps to reduce these costs immensely.

3. Repair water leaking windows with a silicone putty. The silicone putty can help reduce the amount of water leaking through a window. If the window is leaking severely enough you may want to consider replacing the window altogether.

4. Remove all the old silicone that may already be in your window. You can use a utility knife to help remove the excess putty from the window. The more you can get off then the better the new silicone will stay.

5. Wear protection when replacing the silicone to keep your eyes safe.

6. Add the silicone around the window seal and let it dry for a while. The longer you let the putty dry then the better. Consider replacing any rotted out wood around your window. Replacing the whole window frame may result in less air and water leakage.
