"They were very helpful and professional. Glen responded to all of my questions in depth and worked hard to get my business to waterproof and eliminate mold. There have been a few hard rains since they completed their work, and I haven't had any water in the basement so far."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"Called about a basement sewer backup and couldn't be happier with the service. This guy is the doctor of draining — diagnosed the issue fast and had everything flowing again in no time. Professional, honest, and clearly knows what he's doing. Highly recommend, don't hesitate to call him if you're dealing with a drain or sewer issue!""

"Good job but a little bit pricey. Also, I have my water tank replace and he did dispose of the old tank. Not even, bringing it out of the basement for me to put into street curbside for recycling pickup. I have to hire somebody to bring it up from the basement."

"All their work was excellent. Not only did they replace our roof and repair water damage in our dining room, we had them do other jobs too. Replacement basement windows, outdoor lighting, and fencing. I would definitely hire them again."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."
