In our 300 unit co-op conversion, one of the units owned by former sponsor had a heat pipe break and flood his renter's unit. Mold and asbestos was then discovered and remediated by the Board, who paid the costs, and now we have issues related to the shoddy repairs done by the contractor who put back the insulation, walls, sheetrock, and somehow, did not put the walls back plumb in one of the rooms. The result is that room grows narrower to the east wall, and anything put against it is crooked. How could this happen? Who is responsible to repair this defect? Also, there are damages to the tenant's personal property and improvements that cost above his policy limits to repair such as replacing his carpet, which we had to pull up after the floors got destroyed by the flood, cleaning his lighting fixtures from the dust and paint caused by the repairs after remediation. Are we responsible for this or is the owner of the unit?
Thanks for advice!
