Long Island Chooses Us

Linda Weiss

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!

The work was done with the utmost professionalism and competence. The service representative was very thorough in examining the dehumidifier, air purifier and sump pump and provided any service needed including draining the pump.

Craig Todaro

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.

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.

ACM Basement Waterproofing did an excellent job in my basement, no more water intrusion. The job was handled professionally and on time. I am happy to recommend them.

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.

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.

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

West Hempstead’s Best Basement Waterproofing Contractor

Too much water or moisture in your basement can spell disaster, leading to mold growth, termites, and wood rot. That’s why we provide expert basement waterproofing customized to the needs of your home.

We use an interior waterproofing system that captures and removes any water entering your basement. Interior waterproofing is effective and doesn’t require exterior soil excavation around your foundation, making it less invasive and expensive.

How Interior Waterproofing Works
To waterproof your basement:

We drill weep holes along the base of your basement walls.
Then, we install drainage channels beneath the weep holes in a channel drilled in your basement floor.
The drainage channel (french drain) is covered by concrete. It sits hidden beneath the floor.
The french drain collects and transports any water from the weep holes to a sump pump installed in the basement floor.
The sump pump pumps the water up and out of your home, expelling the water outside through a discharge line.

The completed waterproofing system keeps your West Hempstead home permanently safe and dry.

Your Local Crawl Space Waterproofing Company in West Hempstead

Like basements, without protection, crawl spaces can become a moisture-ridden mess full of mold, rot, and pests. We use the same interior waterproofing system to protect your West Hempstead crawl space.

This includes installing a french drain perimeter system with a sump pump and discharge line. Keeping moisture out of your crawl space can prevent mold and rot from developing and even protect your upstairs.

The stack effect, also called the chimney effect, results from temperature and air pressure differences between your crawl space and the rest of your home. The cool air in your crawl space rises as it warms, making its way upstairs.

This creates a vacuum in the crawl space, pulling in additional cold outside air, and the cycle continues. By waterproofing your crawl space, you keep mold and mold spores out of your crawl space, which means they won’t be traveling upstairs into the rest of your West Hempstead home.

Top West Hempstead Foundation Repair

If you see cracks along your foundation walls, you may have a problem. Vertical wall cracks are the normal result of concrete shrinking as it ages and usually do not indicate a foundation issue. Buy horizontal cracks are another story.

Horizontal cracks on your foundation wall are the result of external pressure. When it rains, the soil surrounding your home can become full of water, expanding out and putting pressure on your basement wall. Also, during winter months, the freezing and thawing of the soil can cause pressure on your basement walls.

The result is your foundation walls can begin to bow inwards. Over time, this bowing can worsen, and the walls will eventually be at risk of collapse.

Foundation Repair Solutions (Carbon Fiber Straps)

But if caught early enough, your foundation walls can be repaired before you face the costly burden of replacing the foundation.

ACM installs carbon fiber straps along your bowing basement walls. The straps adhere to the wall and are stronger than steel. The straps keep the wall in place and prevent any further bowing. The straps provide a reliable, long-lasting solution for your West Hempstead home.
