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 waterproofing protects your home from the relentless advances of moisture and water intrusion. Beyond its immediate function of preventing dampness and leaks, waterproofing helps maintain the structural integrity of a building.
By thwarting the potential damage caused by water seepage, basement waterproofing helps avert costly repairs and health hazards, such as mold growth. Waterproofing can even extend the longevity of a property, ensuring that it remains a secure and resilient haven for its occupants, even in the face of nature’s most potent challenges.
So, when it comes to waterproofing a basement, here’s our process.
Some houses in Lake Grove have a crawl space instead of a basement. We can still help.
Crawl space waterproofing is a crucial defense against potential structural and environmental challenges. By ensuring that moisture and water are kept at bay, this preventive measure safeguards the integrity of a building’s foundation, preventing issues like wood rot, mold growth, and structural damage.
Additionally, crawl space waterproofing contributes to maintaining indoor air quality and mitigating health risks associated with mold and mildew. Beyond protection, it extends the lifespan of the property, reducing the need for costly repairs down the road. In essence, crawl space waterproofing serves as a proactive investment in the long-term stability and well-being of your Lake Grove home.
Crawl space waterproofing closely resembles the approach used for waterproofing basements. First, the area is cleaned, and any standing water is removed. Next, a perimeter French drain is installed along the perimeter to collect and guide water, efficiently directing it towards a sump pump that is tasked with removing the water from your crawl space. The final result is a clean and dry crawl space for your home in Lake Grove.
In addition to our waterproofing offerings, ACM specializes in fixing bowed and cracked foundation walls for residences in Lake Grove. If you see vertical, horizontal, or step-like cracks in your foundation walls, it’s possible that your basement walls are bowing. Basement wall curving can worsen over time, eventually leading to a risk of collapse.
To fight foundation wall bowing, we employ minimally intrusive yet incredibly effective remedies for foundation repair, using carbon fiber straps. Stronger than steel, these carbon fiber straps are strategically positioned at intervals of four feet along the compromised foundation wall.
Functioning as a stabilizing brace, these straps effectively counteract further bowing, removing the potential collapse risk. The installation procedure is uncomplicated, and the straps can be concealed or even painted over, making them an almost invisible solution for foundation repair.
Water in your basement is more than an inconvenience, it’s a threat to your home’s foundation and your sense of security. At ACM Basement Waterproofing, we’re committed to making the waterproofing process straightforward and stress-free, with reliable solutions that protect your home for years to come.
