C&M Construction Waterproofing (also going by C&M/CM Waterproofing) is a Massachusetts contractor based in Malden, offering basement waterproofing, foundation crack repair, exterior waterproofing, and crawl space encapsulation. Every review on file is five stars and describes a specific water problem solved: a sump pump installed to stop a flooding basement, exterior drainage work around a foundation that had been seeing recurring water buildup, foundation cracks sealed with a clear explanation of the process, and a crawl space vapor barrier paired with mold treatment that cleared up musty odors. One customer, nervous about cracks in a basement wall, said a neighbor recommended the company and that the crew sealed the cracks professionally while explaining each step. Reviewers consistently point to Max (Maxsuel) and his wife as punctual, transparent, and easy to work with — one review described them installing a sump pump system in a 125-year-old basement to keep it from ever flooding again, and another called them the most professional team they'd worked with for communication and attitude. All seven reviews on record are from mid-2025, so the track record is short but specific and entirely positive — worth a call for a basement or foundation water issue, especially given how consistently the write-ups describe the actual work done.

We hired Maxsuel and his team to refresh our basement, and they absolutely exceeded expectations. They replaced the vapor barrier along the walls, and painted the entire basement floor, posts, and stairs. They meticulously sanded all the posts and the French drain area before painting, and even repaired our basement stairs. The quality of their work is outstanding — you can tell they truly care about the details. The team was professional, friendly, and incredibly respectful throughout the entire process. It’s rare to find a crew this committed to both craftsmanship and customer service. Our basement has been completely transformed. Highly recommend!
Reliable and well-prepared professionals! The team was punctual, respectful, and transparent throughout the process. Maxsuel explained every step clearly and exceeded our expectations. High-quality service!
We had lots of water in the basement and called this company. They came and installed a sump pump . They did an excellent job, and we haven’t seen any sign of water since. They are kind people and they worked very clean and organized. I would recommend them to anyone .
Extremely serious and committed company. They performed the exterior drainage at my house in Malden with precision and efficiency. Since then, we’ve never had problems with water buildup around the foundation again. Excellent work highly recommend!
Max and his wife were the most professional team when it came to communication, punctuality, and attitude - I have never worked with a better duo. They were able to quickly install a sump Pump system in our 125 year old basement to ensure it would never flood again. We are very impressed with their work and will utilize them for ALL home repairs and construction needs in the future.
