Water entering finished basement (cove joint?) with large amounts of rain.
Project Location: Ellington, CT
We've had some water come in through the casement windows. The water collects against the foundation and fills over the windows. Only during heavy rains. It's run down the finished side of the wall and stained the carpet. I'd be looking to have a new flooring installed and to see if there is damage to the drywall. Also, to see if you have a solution to my casement windows filling with water.
Project Location: Ellington, CT
A few times a year, especially with excessive rain or after thawing of deep snow we have standing water in our back yard and multiple points of leakage in our basement. Our sump pump also seems to run at least once an hour all year long.
