We have water damage in our basement due to a poorly sealed door from the driveway to the basement. It floods each time it rains, and the drywall has mold at the base. We're looking for a solution to prevent this from happening and to repair the damage.

We have an unfinished basement that we would like to finish (or finish half of it for the teens to hang out in). Waters leaks into the basement several times per year, so we need to seal the basement and address that issue first.

Vicinity of Taninger Rd in Windham
I have a thin long crack in my foundation wall that i would like to determine what options are for repair.
Vicinity of Kendall Pond Rd in Windham
We have about 5 or 6 cracks in our basement (foundation) that leak water during hard rain storms. The previous owners of the house tried to repair the cracks themselves, filling with concrete, but it didn't work. This will need to be removed. The house was built in 1987 and has a poured concrete foundation.

We are looking to finish off a basement room 12x12, for an extra room for company. The basement is in excellent condition and so we are just trying to get an estimate on what the cost could potentially be, and how long something like that takes to complete. Thank you
