Basement flooding
Project Location: Katonah, NY
Hi! Our basement flooding following heavy rains. Has not ceased being wet since last week's storm. Seems to be coming in from the foundation. Help! Thanks!
Project Location: Katonah, NY
I'm reaching out having just moved to Katonah, our home recently had some minor flooding where the floor meets the wall with the heavy rains. We'd love for you to inspect the issue and help assess solutions. It's our understanding the previous owners put in substantial French drains throughout the backyard yet the basement wall facing that yard had some flooding at the foot still. We live on a hillside and think we'll need more solutions in place given the trend of rain.
Project Location: Katonah, NY
Water entering the basement during major storms. Basement floor was re-finished recently, and was dug out deeper than it had been.

I have a crack in my foundation and as a result water has seeped in and rotted some of the wood beams in my crawl space.

Damp basement
Project Location: Katonah, NY
The basement previously re-finished needs a complete overhaul.
Project Location: Katonah, NY
Drainage outside causing wet and dirt to appear on the inside . We just purchased the house and inherited the problems . Floors are already ripped up so we can see the moisture . Concerned about mold behind the sheet rock as we see not sure how long it has been happening
Project Location: Katonah, NY
I'm interested in a free quote for finishing my basement. This would not be considered livable space due to the low ceiling height, though I'd like it to be a more comfortable, cleaner space .

Wet basement\
Project Location: Katonah, NY
Water is seeping into unfinished basement room (rest of basement is finished). We just bought the house, but the water had appeared after each rain.
Project Location: Katonah, NY
I need two pumps in my basement replaced, potentially with new pits installed. I have a finished basement that retains a lot of moisture. Thank you!

Crawl space insulation
Project Location: Katonah, NY
Going away July 18 and would like to install battery backup to basement sump pump
Project Location: Katonah, NY
Our house is built into bedrock on a hill, so we have a utility room which is basically a crawl space. The insulation is falling apart and there is no ventilation.
