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.

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.

Basement leaks can be a thing of the past when you reach out to ACM. We provide reliable, warrantied basement waterproofing systems that protect your basement from water leaks, seepage, and excess moisture.
Like basements, we also work in crawl spaces, installing waterproofing systems to keep water and excess moisture out of your crawl space.
And that’s not all. If you are dealing with bowing basement walls, we install carbon fiber straps as a permanent fix to protect your foundation and prevent any further bowing.
Whether you need a North Babylon contractor for basements, crawl spaces, or foundation work, ACM is your best bet. We have helped thousands of homeowners in North Babylon and across Long Island, so call us today to set up a free inspection and quote.

Basement flooding can be stressful, damaging, and even hazardous to your health. Worrying about a basement flood every time there is a rainstorm in North Babylon can be miserable. Water in your basement can also cause extensive property damage. And wet basements are breeding grounds for mold – mold spores can irritate and cause allergies and asthma.
But ACM can help. It all starts with a free basement inspection. One of our North Babylon basement experts will visit your home and thoroughly inspect every part of your basement to identify the source of the water, the extent of the damage, and how to fix the problem.
Afterward, our expert will sit down with you to answer all of your questions and to explain the appropriate solution customized to your home.
The most effective way to waterproof your basement is with an interior basement waterproofing system, which we install in North Babylon homes.
Basements are just one of the things we help with. If you live in North Babylon and have water in your crawl space, ACM is also your solution.
Using the same system as we use in basements, we provide effective crawl space waterproofing. A french drain is installed around the perimeter of the basement to collect any water, and a sump pump pumps the water safely out and away from your home.
You protect the rest of your home by keeping your crawl space free of water. The stack effect causes any air in your crawl space to be drawn up into the rest of your home.
And if you have mold, dust mites, or musty smells in your wet crawl space, they are pulled up into your upstairs. You protect your whole home by having ACM waterproof your crawl space in North Babylon.
Cracks in your basement should not be ignored. They can be the harbinger of serious foundation problems that need to be addressed. While vertical wall cracks are the normal result of concrete shrinking as it ages, but horizontal and stair-step cracks are a different story.
As the soil surrounding your foundation shrinks and expands from rainfall or winter freezes, pressure is imposed on your foundation walls, causing them to begin to bow inwards, creating cracks. Over time, the calls will continue to weaken until they are at risk of collapsing.
But ACM can protect your foundation walls with carbon fiber straps. Carbon fiber is stronger than steel, and the straps are installed along your basement wall, strengthening the foundation. The straps stop the wall from bowing any further inward, keeping your North Babylon home safe.
For decades, ACM has protected the most important thing for people in North Babylon – their home. With industry-leading products and expert solutions, our Long Island-based team is the waterproofing and foundation repair you have been looking for. So give us a call today to get started.
We make it simple, affordable, and stress-free — with guaranteed results.
