Diamond Construction NYC

The guy is a crook came the first time paid him for the whole year of cleaning the gutter service and still a no show $300 later his name is John marine cor veteran do not get sucked into his bull sh••

I had a leak on my roof in one spot and John said the whole roof has to be replaced. He charged $2000 more than we closed for garbage removal and part of garbage left on my neighbor property. After first rain the roof leaked in three places and he claimed the problem is in HVAC. I called three different HVAC companies and all of them said the problem is not there but in roof. John said there is a 10 years warranty on material and labor. I keep calling him with no answer and he never get back to me.
Just stay AWAY from these guys.

Two weeks ago I contacted John (owner) at Diamond Construction and was extremely pleased with him and his company. Yes, the owner of this prestigious company took my call and promptly arrived during the scheduled time, diagnosed the problem with my chimney and wrote up an estimated description of the scope of work to be done. Then his staff arrived at the scheduled time and performed the work exactly as stated on the contract. I wish other companies held this belief and level of ethics. As an added bonus, I now use less hot water when taking a shower due to the efficiency of the chimney and new liner. I will use this company in the future and recommend them highly to everyone. Thanks again.
