    Mark McAlpin was a pleasure to deal with in every encounter. As the years progressed we had more water in the basement in the spring and fall months in the building I own in the west end of Long Beach . The water table has been rising .He assessed the situation and proposed a two prong plan , to raise the basement floor and to divert the water into a French drain to two sump pumps . There was great value in the estimate for the amount of work to be done . His company ACM waterproofing was extremely professional and courteous. They were very timely and their work was incredibly clean . The basement looks great and Iâ m so very relieved . Itâ s one thing I no longer need to worry about. Thank you

    ACM is an excellent company with a thorough, professional approach to assessing and correcting my basement water problems. Once the job was begun, they worked every day until the job was finished. Extensive irrigation and placement of a French Drain should correct the problems we found when we bought the house. The owner is "hands on" in his approach, and I highly recommend them.

    5.0 Mark C. Massapequa, NY

    ACM did a great job. I was nervous at first because of the scope of the job. By day 2 I was relieved by how clean and careful the workers were being. I was very satisfied with ACM for a French Drain install. Very professional

    ACM basement could not have been any better! Excellent communication and service from start to finish. They show up when they say so, clean up, and did an excellent job. I highly, highly recommend it.

    5.0 Paul T. North Babylon, NY

    Mark and his company do absolutely amazing work. They are professional, courteous, thorough and most of all, honest. We had read their reviews and called for an estimate. After spending time with both Mark and his daughter, we made the decision to use ACM. We are so glad that we did. They effectively communicated what the job would entail and how long it would take. Mark even talked me out of something I thought we needed for our home, saving me thousands. I don't think I have ever dealt with someone in this line of work, more honest than he is. His crew came in and when they left, we had peace of mind, knowing that the work they did would finally keep our basement dry. Not only did they do great work, but they were extremely clean. We would have never known they were there because of the preparations that they put in before any work began. We cannot thank them or recommend them enough. Call them today!
