 Trustindex verifies that the original source of the review is Google. We feel very fortunate to have found this company. I met with Mike regarding leaks in the basement. He assessed the entire house, gave me options and clearly explained the process. Everyone from Mike, to the secretary in the office to the workers were absolutely amazing. They did the work as promised, gave us a reasonable price, and left the place immaculate. We could not be happier with the results! This is a great family owned business. You can’t go wrong!

 Trustindex verifies that the original source of the review is Google. Mark took it upon himself to come to my home and examine my issue himself.  He is knowledgeable not only in basement waterproofing, but also in land grading, excavating and several other adjacent topics.  While it was concluded my issue was not foundation oriented, he did not hesitate to propose several other creative ideas to help address my issue.  He has a great disposition, and I would not hesitate to recommend his services to others.

 Trustindex verifies that the original source of the review is Google. I bought my house 24 years ago, and for 24 years I lived with water coming in to my finished basement.
A few years back I hired another company to put in a French Drain System which never worked.
As the storms got worse the water in my basement increased.  Because of my previous experience I was hesitant to hire another company until I read about ACM and met Mark who was highly recommended by my Home Service Company.
Mark spent about 2 hours explaining the process, and what was needed.
In February 2025 ACM put a extensive French Drain System  which included taking down the sheet rock walls, demoing tile and placing a membrane along the whole perimeter of the drain system. All of this work was completed in 3 days exactly what Mark said.
The guys were professional, polite, and best of all they were careful to save my Radiant Heating System which was under the tile.
Since the French Drain System was placed I have not had 1 drop of water coming into my basement.  I am very grateful to Mark's ACM Company, and was able to refinish my basement without fear of water damage.
I highly recommend ACM Basement Water Proofing to all who are having water problems with their basement.

 Trustindex verifies that the original source of the review is Google. I chose ACM because of their "Best of Long Island" award, and I'm glad I did. Mark's crew (led by Joe) installed an interior French drain  and a sump pump in our basement. Six months later, we've had no problems with water. These guys know what they're doing.

 Trustindex verifies that the original source of the review is Google. My wife and I would like to say thank you to Mark and his team for their excellent work installing a French Drain in our finished basement. For years we had to worry about flooding if we got a large amount of rain in a short time. The entire staff was totally professional. knowledgeable, competent and efficient. They were clean and caring and after each day they protected the whole worksite. Without a doubt, we would recommend them for all your basement waterproofing needs.

 Trustindex verifies that the original source of the review is Google. I called acm after finding water in the basement. Mark answered the call and quickly helped diagnose the issue. He guided me to check baseboard and sure enough a broken valve was causing this leak. It's good to find someone to help a homeowner without rushing to take their money. It's good to find a honest business man

Basement Waterproofing in Rocky Point

Every home in Rocky Point is unique and requires an amazing basement waterproofing solution, so ACM creates internal waterproofing systems customized to your home’s needs.

Generally, interior basement waterproofing involves:

Drilling weep holes along the base of the basement walls along the basement perimeter.
Adding a trench in the basement floor below the weep holes.
Installing a french drain in the trench to collect any water entering through the weep holes and then covering the trench with cement.
Putting in a sump basin and sump pump to collect any water captured in the french drain and pump the water out to an exterior discharge system

Waterproofing your basement provides benefits beyond just a dry basement. A dry basement means no mold, mold spores, or allergic reactions. A protected basement can also increase your home’s value and provide additional usable space.

Most importantly, knowing that the basement in your Rocky Point home is protected from moisture gives you peace of mind.

Crawl Space Waterproofing

Not all houses in Rocky Point have a basement; yours might have a crawl space instead. The good news is that ACM also works in crawl spaces.

Like basements, we provide expert crawl space waterproofing to keep your crawl space and the rest of your home safe from water and moisture damage.

Waterproofing the crawl space follows many of the same steps as basement waterproofing. The area needs to be cleaned out and any standing water removed. A perimeter french drain is installed to collect any water, which is transported to a sump pump that removes the water from your crawl space.

The result is a clean, dry crawl space in your Rocky Point home.

Rocky Point Foundation Repair

Along with our waterproofing services, ACM fixes bowing cracked foundation walls for homes in Rocky Point. If you see vertical, horizontal, or stair-step cracks in your foundation walls, your basement walls may be bowing. Over time, your bowing basement wall will grow worse and potentially collapse.

We use minimally invasive but completely effective foundation repair solutions – carbon fiber straps to address the issue. Stronger than steel, carbon fiber straps are placed every four feet against the damaged foundation wall.

The straps hold the wall in place, preventing any further bowing and removing the potential of any potential collapse.

The installation process is straightforward, and the straps can be covered up or even painted over – making them a nearly invisible foundation repair solution for your Rocky Point home.
