 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.

 Trustindex 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. 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 Valley Stream

Water in your basement is never good news. A wet basement is the perfect breeding ground for mold, mold spores, and insects. Water can also cause thousands of dollars of property damage to whatever you have stored in the basement.

To keep water at bay and out of your basement, you need to have ACM install an interior basement waterproofing system in your Valley Stream home.

The interior waterproofing system consists of a perimeter french drain, which is installed below the floor next to the basement wall. The french drain captures any water that seeps into the basement, keeping it from reaching walls or floors.

The water is transported down the french drain to a sump basin that also sits below the floor. A sump pump in the sump basin pumps the water up a discharge pipe. The pipe leads outside where it expels the water, either out to the street or in the yard out a bubbler pot (far enough away where it can’t get back into your basement).

With the new basement waterproofing system in your Valley Stream home, your basement will stay safe and dry.

Valley Stream Crawl Space Waterproofing Contractor

Our waterproofing expertise in Valley Stream covers not only basements but also crawl spaces. Like a wet basement, a wet crawl space can become home to insects, mold, and rot. The stack effect also pulls humid, dirty air from your crawl space up into the rest of the house, where it can cause allergies and irritate asthma for you and your loved ones.

Like the basement, the answer to water in the crawl space of your Valley Stream home is an interior waterproofing system. The system includes a French drain, sump basin, and sump pump (along with a backup sump pump) that collects and removes any water that invades the crawl space. Controlling the water in your crawl space helps protect it, improve the air quality of your upstairs, and protect the health of your family.

Foundation Repair for Valley Stream Homeowners

If you see cracks in your basement or foundation walls, they may indicate an underlying issue. The outside pressure from soil and groundwater can push your walls inward, causing them to bow, lean, and shear. Over time, the issue will continue to worsen until the foundation requires complete replacement or risks collapsing.

But if you catch the problem in time, ACM can fix your Valley Stream foundation problem with effective, permanent solutions at a much lower cost than foundation replacement.

We install carbon fiber straps flush against the foundation wall. The straps securely hold the foundation walls in place, keeping them from shifting further. Not only do the straps fix the foundation issue, they can also be covered up or painted over – making them a non-invasive, effective solution for any problems you are running into in Valley Stream.

We Fix Wet Basements and Damaged Foundations in Valley Stream

If you live in Valley Stream and are dealing with crawl space, basement, or foundation issues, please don’t wait for them to grow worse. Let ACM nip the problem in the bud with permanent, reliable, proven solutions. Give us a call to schedule your estimate and quote.
