Wet basement drains to a drywell. Seems to be blocked
Project Location: Brooklyn, CT
I'm looking to purchase a home, but seller said that support beam has "shifted" when he first bought home 30 years ago and has been like that since. Said it was not a problem and just wanted me to know but I'd like to confirm if it's ok or not.

Wet basement
Project Location: Brooklyn, CT
We recently renovated a 100 year old building. The contractor put posts for support in the basement and a new support beam on the first floor. The upstairs is very uneven (feels like it's leaning toward the center) I definitely thing our issues stem from lack of support in the basement. :)

Just need an estimate for a sump pump install (dig hole, place sump pump, pipe outside).. easiest way to contact me is email. so please email me. thanks
Project Location: Brooklyn, CT
I would like to replace the carpet and pad in a basement room, sized 12X10.5, with waterproof flooring.
Project Location: Brooklyn, CT
The water table seems to have risen during the last storm and despite my sump pump working full time, at least 8-10 inches of standing water greets me every morning that I go down to the basement.
Project Location: Brooklyn, CT
We would like to get an idea about the cost to completely waterproof our basement and partially finish it. We have gotten almost 2' of water two separate times. At other times, we can see water slowly seep in during heavier rains. We have a concrete poured foundation with an existing sump pump (that doesn't always do its job). I have no idea what to expect cost wise and would like to at least be able to start planning/budgeting for this.

Stone/brick foundation settling and bowing out into soil.
Project Location: Brooklyn, CT
Project Location: Brooklyn, CT
During the heavy rain storm Friday, Aug 11, water entered our basement through both window wells, flooding several rooms in the finished basement. This has happened once before, 3 years ago. We need a permanent fix for the window wells.
