David Montoya came to our home for an estimate and was 2 hours late for that appointment and that should have clued me in on what his responsiveness (or lack of) would be. He was very convincing and artistic when drawing HIS version of what would be in our backyard. We had a patio, walkway, kitchen area, pizza oven, firepit, water feature and wall and the worst part of the job is the patio as it puddles in several locations I was told he would "grade" it so the water would run off. They maked an "X" where it puddled then drilled holes and it still puddles since they clog. I did not sign off on having holes throughout the patio and never should have made the final payment. There were several times throughout the process that we asked for references and he only took us to one location that he was currently working on. I presume it is because he has messed up every customer he has had contact with and are unable to use them as a reference. The disprespect for our property by him, his crew and the people in the class was unforgiveable. We asked the second day to have everyone clean their trash and to throw cigarette butts, etc in trash and I still had to clean up after them everyday. When I spoke to Dave on the last day, I said I had a punch list of items and would not give him final payment until they were done. He became very argumentative and spun his tires as he left telling me he knew this would happen. We gave him a check at every part in the contract and he cashed them the same day without a problem. He also sent aggressive text messages until I paid him which was 2 days later even though the job was not done correctly - I did not want to be harrassed. Our advice is to DO YOUR HOMEWORK and I would NEVER have Dave or any distributor of his back on my property. We looked into legal action and believe the attorney general in MA is looking into his many alias businesses and were told by a couple attorneys it would cost us more to chase him and even if it was ruled in our favor, he would just close down and open under another name. We have to rip out the kitchen area and the entire patio and walkway to be done right. He lied about ever doing a pizza oven and certainly does not know anything about kitchen areas. He claims to have a contract with Home Depot and I hope they do their homework too before getting into business with him. A modern day snake oil salesman....beware of the con artist!
