Dealing with Mold on Your Windowsill
I received a call from a homeowner who was concerned about mold growth on their windowsill. They were curious as to why there was mold in their windowsill and wanted to know if it was possible to replace the sill without replacing the window if the mold growth was on the inside of their house.
Your Questions, Answered
Q: Can I replace my windowsill without replacing my windows?
A: The quick answer to this question is yes! We can replace your windowsills without having to remove or disturb your existing window.
Q: Why is there mold on my windowsill?
A: Leaking windows and condensation are two of the biggest culprits of windowsill mold. We recommend having a contractor check your window seal to make sure that the mold isn’t caused by water getting through the window. Condensation is especially prevalent in bathrooms and kitchens because of the use of hot water and steam.
Q: Can you still replace my windowsill even if my current sill is moldy?
A: Yes, we can still replace your windowsill without disturbing your windows even if your windowsill is moldy. In this case, and in most cases when replacing windowsills, we recommend replacing exterior window trimming with a PVC windowsill.
The advantage of PVC windowsills is that they are resistant to moisture, able to withstand extreme temperatures, and are mechanical strength (able to withstand the stress of physical forces).
However, if your contractor finds that your windows are leaky, you might want to consider getting your windows replaced with a better seal. This will prevent all mold or mildew growth on your walls.
