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.

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.

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.

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.

Take a look at our testimonials page for reviews from customers from other towns.
In Baiting Hollow, basement water issues often reveal themselves through what homeowners store downstairs. Cardboard boxes get moved to closets upstairs. Holiday decorations go into plastic bins. Important documents never make it to the basement at all. These adjustments happen gradually, but they point to a water problem that has never been addressed directly.
ACM Basement Waterproofing installs interior waterproofing systems that let homeowners use their basements without worrying about what might get ruined. Perimeter French drains capture groundwater before it reaches the floor, directing it to sump pumps for removal. Crack repairs and drainage channels seal off specific entry points. For Baiting Hollow homes where the basement has become a place to avoid rather than use, ACM’s systems make the space reliable again.
Crawl spaces in Baiting Hollow can quietly affect energy costs without homeowners realizing the connection. Moisture beneath the house creates a humidity load that air conditioning systems have to work harder to manage. Damp conditions also reduce the effectiveness of insulation, meaning heating and cooling both become less efficient over time.
ACM provides crawl space waterproofing in Baiting Hollow that targets moisture at ground level. Crawl space drains and sump systems remove water from beneath the home, reducing the humidity that works its way into the living space above. Lower moisture levels in the crawl space mean less strain on HVAC systems and insulation that performs the way it should.
Foundation cracks in Baiting Hollow basements sometimes get patched and repainted without addressing what caused them. A few years later the crack returns, or a new one forms nearby. Cosmetic repairs can hide damage temporarily, but they do nothing to stabilize a wall that is still under pressure from the surrounding soil.
ACM specializes in foundation repair for Baiting Hollow homeowners, using carbon fiber reinforcement systems that address the structural problem rather than just the visible symptom. Carbon fiber strips bond to the foundation wall, holding it in place and preventing further movement. For walls that have been patched before without lasting results, ACM’s approach stops the underlying cause. Combining foundation repair with waterproofing also reduces the saturated soil pressure that drives continued cracking.
At ACM Basement Waterproofing, we transform foundation repair into a seamless experience. By partnering with you, we offer clear guidance and innovative solutions to protect your home for the long term, prioritizing your peace of mind.
