"Rahat Construction did an amazing job repairing my basement and waterproofing the exterior of my house after Hurricane Ida. They regraded the cement, replaced the basement doors, re-fortified and repainted the damaged basement walls and replaced the badly cracked cement on my sidewalk. They are highly responsive, they work very quickly and carefully, and above all, they care about their customers—always taking time to explain decisions and new issues as they arise. This is the second time I’ve worked with them, and I would hire them again in a heartbeat."

"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."

"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

"I needed to have concrete slabs laid out around my house foundation on exposed grass/dirt areas to drain water away from the foundation as the basement was unreasonably humid during summer months. Kams estimate was reasonable, so I had his crew do the work which occurred over a period of 2 days. I am satisfied with the results."

Basement Waterproofing questions, answered by experts

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.
