"They were very helpful and professional. Glen responded to all of my questions in depth and worked hard to get my business to waterproof and eliminate mold. There have been a few hard rains since they completed their work, and I haven't had any water in the basement so far."

"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."

"I used William, and his firm for a bad windstorm claim, which he and his adjuster dealt with my insurance company (effortlessly I must say) and achieved one hell of an amazing settlement! Courtesy, professionalism, friendly, and very accommodating to say the least. A vast amount of different professionals for all your needs. From insurance claims to building a home from scratch. I look forward to using this company again, at the very least, getting guidance on anything to do with my home. Thank you all!"

"Had a backup a few days before and wanted to determine if it was a simple clog or cesspool related. They sent out a tech (Jimmy) the same day. He located both cesspools and walked me through my options. He was honest and patient, answering all my questions along the way."

"Called about a basement sewer backup and couldn't be happier with the service. This guy is the doctor of draining — diagnosed the issue fast and had everything flowing again in no time. Professional, honest, and clearly knows what he's doing. Highly recommend, don't hesitate to call him if you're dealing with a drain or sewer issue!""

"All their work was excellent. Not only did they replace our roof and repair water damage in our dining room, we had them do other jobs too. Replacement basement windows, outdoor lighting, and fencing. I would definitely hire them again."

"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

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.
