Very well all the work was done in a professional manner with no problems

It went very well. Mark was very easy to work with and performed exactly as promised His crew was meticulous they covered and protected everything. They answered all of our questions and were extremley polite. neat helpful and respectful I would recommend ACM without hesitation

Set up flood mitigation after Sandy and we have been dry ever since! Came back for a driveway drain last year, works like a charm. Great work!

Working with Mark and his team was such a pleasure. Patient, professional, well-communicated and informed! are just some of the characteristics you can expect when working with ACM. I would highly recommend. They are definitely the experts in basements!

I am so glad we finally decided to install a french drain in our basement on the east end of Long Island. Mark, the owner of the company, is very knowledgeable when it comes to waterproofing. After setting the date, they showed up on time and did a fantastic job. Now I am worry free; when it's raining hard, the basement is dry and clean. I couldn't be happier with my choice. Highly recommend this family owned company!

We used ACM 7 years ago to install a French Drain and sump-pump for the southern side of our lower level. It solved our water leak problems. This past week we used them again to install a similar system on the northern side of our lower level.

We installed French drains in our basement in early June. Mark and his crew were extremely neat and professional and offered the best solution for how to address my water issues. They were also very accommodating to my early morning work schedule. With all the rain we've had in the past couple of months, I would previously have definitely had some flooding but my basement has been completely dry. Definitely worth it!

Since owning a 109 year old home I've had a need to contact various contractors for a variety of issues and have not always been satisfied with the results. But contacting Mark and dealing with his professional staff was refreshing and restored my faith in American craftsmanship and business ethics. They did not only do a outstanding job, keep all appointment dates, cleaned up after the job, they followed up the next day via the telephone and even came by the house to make sure everything was working properly. OUTSTANDING in every aspect. A Thank you Patrick Minter Brightwaters NY

Very Professional. Reasonably priced. Extremely neat. Left area cleaner than they found it.

Mark seems to be very knowledgeable about his work and made us feel comfortable in trusting him with our house. He and his team were courteous and professional throughout the 3-day job. They left all their work areas clean each night and after wrapping up and made quick work of a very labor intensive process. Would definitely recommend.

Gave a reasonable estimate without suggesting any unnecessary fixes, came punctually and did the work, cleaned up well, everything is working fine.

They did an excellent job. Clean up after they did it. I'm so happy. They were perfect. The basement was left spotless. It was so great.
