The guys came for initial inspection and work was scheduled since I signed the contract. But the guys came for the work did not do the work excusing that water heater exhaust is not installed properly in basement. I was expecting an update on possible resolution but did not get any after more than two months.

What surprises me is:
1. If there was an issue that should have been noted during initial inspection
2. There is no work related to basemen in the contract I signed. In fact I specifically asked regarding basement insulation and they said basement is fine and no further work needed.
It seemed to me the guys chickened out since the attic has lot of angles. They took out some insulation for prep work but did not put those back in. I am going to make complaint to mass save and BBB.
