"Jeff did a great job on our complete basement bathroom remodel last December so we asked him to do a small job of installing a vanity. The job was done quickly and efficiently. The price was reasonable. Everything was cleaned up. I highly recommend Northgate Home Improvement and will gladly hire them in the future."

"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."

"We've never had luck with major home modifications—this was smooth sailing the entire way. Our project was a teardown and complete re-side, and Cocos did a fantastic job. We have a tricky home with a lot of angles that make no sense—Cocos did a brilliant job strategizing how everything should be executed, and the 50-year-old home looks brand new. Danielle, Keith and Matt not only executed at the highest level, they stayed in communication literally every day to make sure there were no surprises and that we were happy with the progress. If you're looking for a home siding partner, don't hesitate to hire Cocos. They were top notch and we are very happy/"
