Writing this review to let others know what this company did to my basement. I had to have a backwater valve installed at my house and after it was installed, my basement flooded with raw sewage. There was feces and pee in my floors, subfloors, you name it. I am attaching a picture here because a picture is worth a thousand words.
If you desire raw sewage in your basement and no help from them afterward, go with them.
The photo I am attaching here is BEFORE WAY bigger problems arose (this is only step 1). There is sewage in just about every part of my basement.
They know this. The building inspector said he only inspected what was visible, not the faulty flap 6 ft down.
This is supposed to have a 25-yr warranty on top of it - do you think they honored that in any way?
