Waterproofing & Foundation Repair in Suffolk & Nassau Counties

Waterproofing Long Island homes can be a challenge for DIYers and inexperienced waterproofing companies because there is no one-size-fits-all solution. The soil composition, ground layout, and building structures of Long Island are unique in that there is so much variation from area to area. Because of this, Long Island basement waterproofing solutions vary greatly from one house to another. To solve the issue, an accurate diagnosis of the problem is crucial.

Basement Waterproofing

Your basement is part of your Long Island home, but water or moisture can make it a battleground. A wet basement can result in mold, rot, insects, rodents, and property damage. But ACM’s Long Island basement waterproofing system protects your basement. We use non-intrusive, effective interior french drains, sump pumps, and discharge lines to keep your basement safe and dry. If you have basement water problems, call Long Island’s basement waterproofing company – ACM.

Crawl Space Waterproofing

Not every Long Island homeowner has a basement. Instead, you could have a crawl space. Unfortunately, crawl spaces fall prey to the same issues as basements – water, mold, insects, and rot. But, unlike a basement, crawl spaces often go unseen, but that doesn’t mean they should be ignored. The humid, mold-spore-filled, poor air from your crawl space is sucked up into the rest of your home, where it can cause health issues. A Long Island crawl space waterproofing system can make all the difference by protecting both your crawl space and your upstairs.
