## The honest read

C&M Construction Waterproofing is a small, owner-run waterproofing outfit in Malden — Maxsuel and his wife run the crew personally — built around the basement-and-foundation problems that keep homeowners up at night: water in the basement, cracks in the foundation wall, a damp crawl space. All seven of its Google reviews, posted in 2025, are five-star.

The 2025 reviews describe concrete fixes rather than vague praise. One homeowner had a sump pump installed in a 125-year-old basement specifically to stop it from ever flooding again; another called the company out for exterior drainage work at a Malden house and reported no water buildup around the foundation since. A third saw cracks forming in a foundation wall, got them sealed with the process explained step by step, and came away confident in the repair. In a crawl space job, C&M installed a vapor barrier and treated an existing mold problem, and the homeowner said the musty smell was gone afterward. One basement refresh also included replacing the vapor barrier along the walls and painting the floor, posts and stairs — sanding the posts and the French-drain area first.

There isn't a downside on record yet — with only seven reviews, all posted close together, there simply isn't much history to check against.

Good fit for the classic wet-basement and foundation-crack calls around Malden, especially for anyone who wants the sump pump or drainage system explained as it goes in; given how new the review history is, it's worth asking for a couple of recent local references before committing to bigger work.

**Strengths:**
- Sump pump installs — stopped repeat basement flooding in a 2025 job
- Exterior drainage fix — ended foundation water buildup at a Malden home
- Foundation crack sealing — explained the repair process step by step
- Crawl space mold — vapor barrier and treatment cleared musty odors
