Commercial cleaning throughout Greater Montreal
From downtown Montreal to the business parks of Laval, Longueuil and the North Shore, NMS provides cleaning for offices, retail stores, clinics, condo buildings and industrial facilities. Every contract is built on a clear scope of work: the tasks to be done, how often each one happens, and the priority areas — washrooms, kitchenettes, lobbies and meeting rooms.
Our crews work evenings, overnight or on weekends so cleaning never gets in the way of your operations, and regular quality follow-ups ensure consistent results from one visit to the next. Need periodic services on top of regular cleaning? We also coordinate window cleaning, floor care and carpet cleaning under the same agreement.
