 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.

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 Baldwin

In Baldwin, some homes sit in areas where the water table stays relatively high year-round. Groundwater doesn’t just show up during storms or snowmelt. It presses against the foundation consistently, finding its way through cracks, joints, and porous concrete whenever the pressure builds.

ACM Basement Waterproofing installs interior waterproofing systems designed for conditions where water is a constant presence rather than an occasional event. Perimeter French drains relieve hydrostatic pressure at the foundation edge, channeling water to sump pumps that remove it continuously. Crack repairs and drainage channels address specific entry points. For Baldwin homes dealing with persistent groundwater, ACM’s systems provide year-round protection rather than temporary fixes.

Crawl Space Waterproofing for Baldwin Homes

Crawl spaces in Baldwin sometimes show signs of moisture damage in the insulation itself. Fiberglass batts installed between floor joists absorb water over time. Once damp, the insulation sags, pulls away from the subfloor, or falls to the ground entirely. What was meant to keep floors warm and reduce energy costs ends up doing neither.

ACM provides crawl space waterproofing in Baldwin that addresses the moisture causing insulation failure. Crawl space drains collect water at ground level, and sump systems remove it from under the home. Reducing moisture beneath the house protects structural framing and allows insulation to function properly. Floors feel warmer, energy efficiency improves, and the crawl space stops undermining the comfort of the home above.

Foundation Repair for Bowing Walls in Baldwin

Foundation wall problems in Baldwin don’t all require the same repair. A wall with minor inward bowing needs a different solution than one that has moved several inches and continues to shift. Choosing the wrong approach can mean underbuilding a repair that fails or overbuilding one that wasn’t necessary.

ACM specializes in foundation repair for Baldwin homeowners, matching the repair method to the severity of the problem. Carbon fiber reinforcement systems work well for walls with moderate bowing, bonding directly to the concrete to stop further movement. For more severe cases. ACM’s assessment identifies which approach fits the situation. Pairing foundation repair with waterproofing also reduces the saturated soil that drives wall movement over time.

Getting Your Baldwin Home Prepared

We make foundation repair a simple and easy experience for you. At ACM, we don’t just fix your basement; we work alongside you, offering clear guidance and innovative solutions to safeguard your home for the long haul. Your peace of mind is our top priority.
