M&M Multi-Cleaning Services, LLC

M&M Multi-Cleaning Services is a family-owned house and office cleaning company based in Merrimack, New Hampshire, run by Herminia and Marco Maldonado, covering Merrimack, Nashua, Manchester, Bedford, Amherst, Hollis, and Goffstown with house, deep, move-in/out, office, commercial, carpet, and Airbnb cleaning. What sets this business apart isn't just volume — 64 reviews since 2014, nearly every one five stars — it's how long people stick around. One reviewer says they've used M&M for almost 20 years; others cite 12, 10, and 7-plus years of weekly or biweekly service, several explicitly saying they trust the crew alone in their home when they're not there. A 2026 review describes a deep clean of a 3,000-square-foot home ahead of putting it on the market, calling the team professional, hardworking, and extremely thorough. Another describes the company cleaning a 250-unit apartment building to a consistently spotless standard. The kind of detail that comes up again and again is care that goes beyond the checklist. A 2023 review describes the crew noticing and flagging safety issues in an elderly relative's home to the reviewer, who lives out of town — the kind of attentiveness that goes well past scrubbing surfaces. A 2017 review describes a post-move-out deep clean that removed years of built-up grease and dust from kitchen cabinets, walls, and ceiling fans across a full condo, including two bathrooms and the basement, leaving the place spotless. Reviewers describe a genuinely consistent operation: on time, communicative, flexible with scheduling changes, and staffed by employees several reviewers call hard-working, honest, and cordial by name — Herminia and Marco themselves, along with their sons, come up repeatedly as being personally involved in the work. HomeAdvisor and Angi each independently show a perfect 5.0 rating across dozens of reviews, matching the Google pattern. Across more than a decade of written reviews here, nothing points to a real complaint — the lone four-star rating on file is fully positive in its text, just short of a perfect score. For recurring house cleaning, a deep clean before a move or a listing, or a larger commercial job, this reads as one of the more thoroughly reviewed, consistently trusted cleaning companies in the Nashua-Manchester area — the kind of business people stay with for a decade or more rather than switch away from.
