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.

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.

In low-lying Copiague, where heavy rain and rising groundwater often spell trouble for homeowners near Montauk Highway or the Great South Bay, issues like basement flooding, foundation cracks, and musty crawl spaces are all too common. But, ACM Basement Waterproofing has been helping Copiague residents safeguard their homes from these threats with expert basement waterproofing, crawl space solutions, and foundation repairs designed to last.
Whether you’re near Dixon Avenue or further inland, water damage can creep in silently—undermining your home’s structure and air quality. Let ACM’s experienced team in Copiague inspect your property and stop the problem at its source. Call today to protect your home before the next storm rolls in.
Customer reviews from Copaigue coming soon! In the meantime, take a look at our testimonials page for reviews from customers from other towns.
Even though it may seem like a small problem, basement water can cause expensive, long-term damage, water damage, ruining property, and even health problems for you and your family. You need to keep water out of your Copaiguebasement—you need basement waterproofing.
But not all basement waterproofing in Copaigue is the same. Some companies opt for cheaper or insufficient products installed by novice but cheap labor. These types of ‘solutions’ may be inexpensive initially, but they will eventually need to be torn out – making them the more expensive solution.
Instead of dealing with that nonsense, call ACM first. One of our Copaigue basement waterproofing experts with years of experience in the field will visit you at your home. They will thoroughly inspect the problem area and identify the root cause in your Copaigue home. Then, they will sit down with you to discuss the issue and the recommended solution, answering all of your questions along the way.
In our experience, an interior basement waterproofing system is the most effective answer to basement water. In an interior waterproofing system, a french drain is installed below your basement floor along the basement perimeter where the basement wall meets the floor. The french drain is covered with cement, making it invisible, but underneath the cement, the french drain captured any entering water.
The water is channeled to a sump basin fitted with a sump pump. The sump pump pumps the water up and out a discharge line safely away from your home. The whole system runs as needed, ensuring that your Copaigue basement stays dry.
Save yourself the stress and expense by calling ACM Basement Waterproofing. Our team of Copaigue basement waterproofing experts is committed to ensuring your basement remains in shipshape condition and steers clear of potential hazards.
If you live in Copaigue and are dealing with basement water, you don’t need to deal with it any longer. Call us today to get started.
What about crawl spaces? Not every home in Copaigue has a basement, and ACM helps with crawl spaces as well. Like the basement, a crawl space can suffer from water leaks and high humidity. The stack effect results in the crawl space air being pulled up into the rest of your home, so whatever is in the crawl space is now upstairs with you and your family.
We protect your crawl space just like we do your Copaigue basement. We create a channel around the perimeter of your crawl space floor. A french drain is placed in the channel connected to a crawl space sump pump. The waterproofing solution keeps water and excess moisture out of your basement. By keeping out moisture, you keep out mold, rot, and intruding insects.
If you need crawl space waterproofing in Copaigue, ACM is your answer. Schedule your free inspection today.
Along with waterproofing homes in Copaigue, we also solve foundation issues. If you walk downstairs and see cracks running along your basement walls, you need to give us a call. Over time, the cracks will likely continue to expand, growing larger and becoming more expensive to repair.
If the cracks grow large enough the stability of your foundation walls can come under question requiring you to replace your foundation walls, a very expensive solution.
We correct bowing basement walls by installing carbon fiber straps along the walls. The carbon fiber straps hold the walls in place, preventing them from bowing any further. To get started, one of our foundation repair specialists can visit your home to inspect your foundation.
At ACM, we are committed to providing permanent, reliable solutions to foundation water and damage issues in Copaigue. You can rely on ACM to show up on time, do what is promised, and fix your basement woes. So save your spot by scheduling your free inspection and quote today.
At ACM, we focus on more than just completing the job, we aim to provide durable, lasting results. With top tier products and custom solutions for your home, we guide you through each step of the process. We’re dedicated to addressing all your questions and ensuring a smooth, hassle-free experience from start to finish.
