"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."

"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."
