"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."

"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."

Basement Waterproofing FAQs, answered by experts

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.
