One of the worst basement contractors. They were recommended to me by a friend they were really good before and new management has taken over since the pandemic, now they They will try to ask for ever penny for simple stuff that they said would be in the contract. Even if they offer you a good deal I wouldnt go with them they will lie cheat and scam. They have fake reviews to give them good ratings dont go by homestars

They will conveniently forget to

RESPONSE TO OWNER:
1. At no time did I warn or threaten a negative review if damages were not fixed.
2. Why would I contact and expect you to fix the smaller issues that weren't fixed when they were pointed out in the final inspection?
3.

As I clearly stated in my original review, the shower leak was behind the drywall. As such, there was no indication of the leak until the mould worked its way through the baseboards.
4. A plumber confirmed
