    Is there a small puddle appearing on your window sill every time it rains? This is a clear sign of a leaking window. While it may seem like a minor issue at first, over time, it can lead to significant damage to your home. But worry not, we’re here to guide you on how to fix leaking windows and safeguard your home from any potential water damage. Let’s get started!

    Step 1: Identify the Cause

    The first step in fixing a leaking window is identifying the root cause. Water can sneak into your home through a variety of ways. It could be seeping in through the window seal, or maybe the glazing putty has worn out. Other times, it might be due to a crack in the glass or even an improperly installed window. Once you pinpoint the problem, you can determine the best solution. Learn more about the signs to replace windows here.

    Step 2: Gather Your Tools

    Next, gather your tools. Here are some items you might need:

    • Utility knife
    • Screwdriver
    • Pry bar
    • Replacement seal or glazing putty
    • Caulk and caulk gun

    Step 3: Repair or Replace

    Depending on the cause of the leak, you may need to repair the window or replace it entirely. If the seal is broken, you can simply replace it. If the window frame is rotten, you might need to replace the entire window. For a detailed comparison of repair vs replacement costs, check out this window replacement cost guide.
