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.

A small leak in your basement might seem harmless initially, but it can quickly snowball into more significant problems like mold growth, wood rot, and insect infestations. Plus, the longer the water seeps in unabated, the more expensive the damage becomes to fix.
Waiting to fix the issue can quickly cost you a pretty penny. But not all is lost. ACM specializes in comprehensive basement waterproofing in Cedarhurst.
We install interior French drains beneath your basement floors. These drains collect water before it reaches the surface and direct it to a sump pump that efficiently moves it away from your home.
With ACM’s solution in place, you can rest easy—even when the weather turns stormy—knowing your basement is fully protected from water damage. Reach out to us today to get started.
Beyond just waterproofing, ACM also offers expert solutions for foundation cracks. While vertical cracks are often just a sign of settling, horizontal or stair-step cracks can indicate more serious structural issues, such as bowing walls.
This is an issue that you need to have fixed by an expert. Our Cedarhurst foundation repair team uses advanced techniques like carbon fiber strap reinforcement to stabilize your foundation walls. These straps are bonded to the wall, preventing any further movement and ensuring your foundation stays strong and secure.
If you are dealing with foundation issues, we can help. We often find that a home with foundation issues has basement water problems, and vice versa.
If your Cedarhurst home has a crawl space, you are not safe from water intrusion. If water finds its way into your crawl space, it can lead to moisture buildup, mold, and other serious issues.
Luckily, the fix is straightforward. Like in a basement, by installing an interior French drain system paired with a sump pump, we can effectively remove any water and channel it far away from your home. This setup ensures your crawl space remains dry and protected, giving you one less thing to worry about.
ACM has become Cedarhurst’s trusted name for crawl space waterproofing, so don’t hesitate to reach out if you’re facing water issues.
Get Your Free Inspection & Estimate! Whether you’re dealing with water in your basement, foundation cracks, or crawl space moisture, ACM has you covered.
At ACM we prioritize using only long-lasting solutions and high-quality products to protect your home.
