David General Contractor (NYC LIC # 1323355, NASSAU COUNTY LIC # 194961, SUFFOLK COUNTY LIC # 46212-H) 100 Duffy Av Hicksville, NY 11801, Phone: 516-833-6016) failed at doing their job. I hired David to replace a flat roof and the stone gable of the front part for a single attached family house. Their job consisted of leveling the roof to avoid large amounts of water from accumulating on the roof, wrapping both sides of the parapet wall to reach the parapet cups so it can properly insulate the roof and, finally, removing and replacing the broken stones on the front gable roof to ensure safety from any falling stones. None of the above mentioned tasks were done correctly and in fact they were done with extremely poor craftsmanship and it was clear from the result of the job that absolutely zero effort was put into the work. For instance, on the flat roof, David used an EPDM membrane that wasn't properly attached to the fiberboard roof panel on the plywood, which is completely wrong. He also didn't use any waterproof or vapor lining. Furthermore, the materials used on my roof looked old like he recycled materials from previous projects rather than buying new ones. In addition, he did not level the roof correctly causing rain water to sit on the roof for more than 5 days. Another failed part of this project. He did not properly  seal the gutters on both sides causing the rain water, that leaked from the roof, to freeze which affected my and the neighbor's wall. Also, the gutters weren't leveling which caused inches of water to sit there until it evaporated. Moreover, he was supposed to fix the whole gutter system and level that part of the roof using insulation to prevent water from collecting, but he never showed up. For the parapet wall, he left a big gap between the wall and the parapet cups, which caused several problems, including failing to properly insulate my house. This made it unbearable, especially during the cold winter temperatures. Finally, the front gable roof was done poorly. When it was windy, pieces of slate stone began falling off, and water was flashing in all directions. This is really dangerous and unsafe. As mentioned above, I am deeply disappointed with the poor quality of work this company performed on the roofs. I honestly can't believe they have a 5-star rating and over 20 years of experience. They charged me over $14,000 for a job that clearly didn't justify the cost and has only led to further problems and expenses. When I voiced my concerns, David took it upon himself to trespass on my property and my neighbors' to film my roof and all the neighborhs roof, as well when I wasn't home. This is completely unprofessional and unacceptable. I would not recommend this contractor to anyone looking for a team that values customer respect and delivers work with integrity, as they failed on both ends. read more

I wish I could give David more than 5 stars. My insurance company called me informing me that I had 20 days to completely replace my roof, and if I did not, they would drop me. I started looking for different insurance companies to switch to but everyone's price had now doubled because of inflation. I had no choice but to repair the roof. I got 3 quotes, and David's was the best price. I was hesitant to use him because he did not have that many reviews on yelp, but he had many more on google. Because this was a surprise cost, I needed to go with the most economical choice. I am so happy that I chose David. He did an excellent job for a great price. Not only that, but he also completed it within the time frame my insurance carrier needed it to be. David is awesome. I Definitely recommend. read more

David General Contractor installed a new roof on my home 4 years ago. 4 years ago I thought they did a great job for a great price but never wrote a review. Today, I had a leak in my kitchen ceiling and called David because the leak had to be coming from my relatively new roof. He came within 3 hours of my call, climbed on the roof in the rain and found a small hole that had been caused by a fallen tree. He fixed the hole for no charge! David General Contractor is a great company that does great work and has superior customer service. read more

I called David to ask for a quote to replace the roof on my house. He came the next day to inspect the roof and submitted a detailed estimate that evening. I had 5 contractors come by and in the end decided to go with David. He not only had the best price, he is professional, keeps his word, and is respectful. He is a gentleman. He arrived with his guys at the time he said he would and they completed the work in a timely way. They ripped the old roof off and replaced the roof in 1 day! I highly recommend David. read more

David General Contractors replaced our flat roof in Flushing, Queens over three years ago. Today, I recommended them to a friend and realized I had never written a review. We found this company to do excellent work, provide truthful estimates, and were efficient in their execution. Over 3 years later, we are happy to say that we have not had any problems at all. read more

Mr. Piza rescued us from the leaky, buckling roof nightmare that Four Decades Contracting left behind. He did exactly what was needed to correct the problems with the roof itself. He stripped the roof to the bones, reinforced the beams and added new ply wood and shingles. He was also not phased by the surprises he found with the structure. He handled it all like a pro, no complaints, and no quibbling over funds. He explained every new issue he found that fell outside the scope of the contract, told us how he would alleviate the problem, and he fixed them all without breaking the bank. Unlike Four Decades, David's team got it right on the first try, no 3 miserable failed attempts. David's team also replaced the crumbling chimney and modernized it with copper instead of yucky tar at the base. He also replaced the white siding on the attic that the Four Decade's team ruined with tar. David's crew is comprised of professionals with 10+ years experience and it shows in their work. Furthermore, unlike the the Four Decades team, David's workers were cheerful, efficient, tidy and didn't beg for food, drink or money. Also, he took payment after all the work was done and the debris removed. The other guy took the money from the bank, Wells Fargo, they arranged a loan though on the first day of work contradictory to the contract. The only issue I have with David General was their chimney work. They dropped cement and bricks at the bottom of the chimney which blocked off the release of carbon monoxide from the water heater and boiler. In addition, he did not line the chimney to make it up to code according to the chimney sweep company and his referral. After informing David of the issue, rather than sending one of his workers to fix the problems, one week later he emailed me a number with no name of someone else to do the job. The guy came on 9/17 and quoted me $1200 to fix the work. When I asked for his license and insurance information, and an itemized quote, he seemed to hesitate but said he would get back to me in 24 hours. It's been 2 days and I haven't hear a peep. David General is a roofer. he might say he's capable of doing other jobs but I would only hire those who specialize in what needs to be done for those specific jobs. Don't hire roofers to do chimneys, don't hire plumbers to do carpentry, etc, etc. read more
