Brookhaven, NY Basement Waterproofing

If water is seeping into your basement, time is of the essence. The longer you wait to fix the problem, the greater the problem can become. Basement moisture can damage property, mold, rot, and insect and rodent infestation.

The solution is to keep water out of your basement with an interior waterproofing system. ACM’s waterproofing systems capture any entering water in your Brookhaven basement and remove it before it ever causes any issues.

The waterproofing system includes:
*French drain installed below the floor along the perimeter of your basement to capture water
*A sump pump connected to the french drain to expel any collected water
*An exterior drainage system to safely disperse any expelled water

We are proud of our basement waterproofing services in Brookhaven, and our customers are thrilled with the results. If you don’t believe us, just take a look at all of our online reviews. When you call ACM, you know you are calling the best basement waterproofing company in Brookhaven.

Foundation Repair in Brookhaven NY

Along with basement waterproofing, ACM offers foundation repair services in Brookhaven. We secure any bowing foundation walls in your basement using carbon fiber straps.

The straps keep the wall in place, preventing any further bowing or damage. Carbon fiber strap installation is also a much lower-cost option than replacing the entire foundation. But again, the key is time—the earlier you have ACM inspect and repair your foundation in Brookhaven, the less likely you will have to pay for an expensive foundation replacement.

Crawl Space Waterproofing in Brookhaven NY

You may have a crawlspace under your Brookhaven home instead of a basement. Like a basement, water in your crawl space spells disaster – mold, rot, and property damage that only grows worse over time. We prevent crawl space water just like basement water with an interior basement waterproofing system.

An interior french drain is installed along the perimeter of the crawl space, along with a sump pump and a discharge system. Any entering water is collected, channeled to the pump, and pumped out and away from your home, far enough away that it can’t cause any problems. ACM is your go-to solution if you live in Brookhaven and need a crawl space waterproofing expert.
