Leaking Basement Window
6/15/2023 at 12:22:21 AM
I have a basement window with a walkout that has a leak when we get a heavy rain. There is a deck above it with a duradec covering so no rain is actually falling on it. I believe I have sealed the decking from above but the window still leaks. The house has a stucco external on both levels. Is it possible the stucco is leaking or would it still be the window that leaks?

With out looking at your place. I would be looking closer at the top of the deck. Water is getting inside from the deck going through the deck plate and coming out the lower window. Or if you have a window or door above the deck, water could be getting in through them as well. I have seen this issue many times.

Hi Pauline. There is few factors that can cause the leak. To find the leak you have to hire a professional inspector to inspect it all.
Could be roof, stucco or any concrete cracks. Have to be inspected.
Good luck.

Hi Pauline. There are a lot of potential sources of leakage and removal of the stucco will likely be required to get a look at the detailing underneath. Stucco is the most problematic cladding for water entry for a number of reasons; retains moisture, usually not done in a proper 3-coat application (with a 'brown' coat in between the scratch and finish coats, poor membrane detailing, no drainage plane, window detailing poor, etc.) I have examined many failures just like yours primarily involving stucco clad condos.
