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!Posted on Google rose smithTrustindex verifies that the original source of the review is Google. 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.Posted on Google Craig TodaroTrustindex 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.Posted on Google Linda RussoTrustindex 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.Posted on Google Maria LacosteTrustindex verifies that the original source of the review is Google. 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.Posted on Google William RothsteinTrustindex 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.Posted on Google Links2282Trustindex 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.Posted on Google Peter WebbTrustindex 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

Mold in your Long Island basement can lead to property damage and foundation issues and risk your family’s health. If you think you may have mold issues, you need to have professional mold testing. ACM Basement Waterproofing provides reliable, inexpensive basement mold testing services throughout Long Island. Call us to schedule a time for mold testing.
We make it simple, affordable, and stress-free — with guaranteed results.
The humidity from the constant dampness of a wet basement, coupled with an abundance of mold food provides ideal conditions for mold to grow and thrive. In finished basements mold feeds on the sheetrock, wood studs, insulation, doors, window frames, and wood molding. Even unfinished basements in Long Island are a paradise for mold spores – cardboard boxes, books, papers, leather, wooden and upholstered furniture, and wood beams in the ceiling all grow mold.
There are many varieties of mold, some more dangerous than others. Individual sensitivities to different types of mold also vary from person to person. Prolonged exposure, even to relatively non-toxic mold, can cause headaches or respiratory and breathing problems.
ACM offers inexpensive, comprehensive mold testing, which can even be done at the time of your basement waterproofing estimate. The testing involves drawing two air samples – one from the air outside of your house to use as a control, and one from your basement to determine the types of mold, the concentration of each type, and how elevated the mold levels are considering the normal levels in your neighborhood. The test includes a full lab report documenting the results.
If you have visible mold, or if you have a finished basement where mold can be lurking behind the walls, ask about getting a mold test.
Before removing mold in your Long Island home, it is important to first eliminate the water source that is causing the mold problem. If the water problem is not addressed, the mold will come back.
