I found John to be both straightforward and honest. My project was difficult and required structural engineering and special inspector. John arrived on site every day much earlier than required, and I watched him analyze the issues and come up with a very creative solution to a major problem with my house. His crew works very fast and the final result is outstanding. If you want perfection and attention to details then John is your best Contractor. In my opinion, John is by far the best-qualified contractor you can find.

This guy is a liar ! STAY AWAY ! He will charge you even for the time he spends at his house. Ended up paying 5 times more then we agreed and received poorly remodeled house. He is going to retire soon and he doesn't care about his business anymore. He tries to charge as much as possible and do as less as he can !

He charges by the hour for the number of people you want on the job. If you choose 4 which includes theoretically him, he is not there 85 percent of the time. In addition he drastically underestimates how much time they need. If you ask his right hand man, he'll tell you realistically it needs at least 5 times more hours. I ended up paying 8 times the estimate cost and the job was still not completed. He also recommends a person (Artie) to buy used kitchen appliances from, who is in my opinion a con man.
