    My brother installed a hinged window well cover earlier this year. Where the cover meets the brick of the house he used clear silicone seal. A couple of weeks ago we discovered that the silicone seal did not adhere well to the brick and has pulled away. Before I attempt to seal this again, I'm wondering if anyone has any specific suggestions for a sealant or caulk that would adhere well to both the plastic window well cover and the brick.

    A masonry type caulk might work well and cleaning the surface before application of any caulk is the most important thing you can do...it must be bone dry when applied also...

    Thanks for the reply Cass. Apparently the masonry caulks are made of polyurethane, which is a pretty aggressive sealant. If anything can stick to both the brick and the plastic, that would be it.
