"We wanted to finish our basement but was hesitant bc of our flooding problems. Home healthy homes solved that for us. They came in waterproofed and removed all mold. We have had heavy rainstorms since and no more floods! Glen and the team are so professional and could not be more helpful. They are reasonable and worth every dime! Highly highly recommend!! They go above and beyond."

"James, his brother Mike and their crew were all you would be looking for in a company. Very polite and respectful. They did all the work as per contract in the time specified. Their workmanship and attention to detail was exceptional. We had other estimates for the same scope of work which came in much higher. We would definitely recommend them for anyone considering basement waterproofing."

"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."

"Our washer was not emptying to the cesspool, was backing up and draining to the basement floor, we researched a few cesspool companies and was impressed with the reviews and lack of complaints thru Angie's List and the BBB. From the 1st phone call, they were friendly, courteous and prompt.
When the technician came he assessed the problem, pumped out 1000 gallons and told us we would need a new pool. The pools are 45 years old, made of cinderblock and were approx. 20 feet down. He gave us a price, we scheduled the work.
They arrived on time and when they opened the pool it was almost full, again They ran into a few problems and solved them (no additional cost to us). The work was completed to our satisfaction I would highly recommend this company. Everyone was efficient, did what was expected in a highly proficient manner. The crew and owner very friendly, took their time to explain everything and my son in law has made a new friend!
Thank You Priority!
