# Commercial Garage Doors in Hamilton, Burlington and Niagara: Who To Call > 905 Trades is residential only. Rolling steel doors, dock levellers, high-speed doors and 24/7 commercial service are handled by Commercial Garage Doorman, the commercial division of our residential partner. Who to call, what counts as commercial, and what we still cover. Source: https://905trades.ca/commercial-garage-doors/ · Last updated: 2026-09-20 · 905 Trades --- 905 Trades is residential only. For a rolling steel door, a dock leveller, a high-speed door or anything on a loading bay, the people to call are Commercial Garage Doorman on [905-536-5369](tel:+19055365369). Same family business as our residential garage door partner, separate division, and they answer commercial calls around the clock. ## Why does 905 Trades not handle commercial doors? Because it is genuinely different work, not because we are being fussy about it. A house has one or two sectional doors on torsion springs. A warehouse has rolling steel curtains, dock levellers, high-cycle spring packages rated for hundreds of openings a day, and a building that loses money every hour a bay is shut. The scheduling is different, the parts are different, and the paperwork is different: commercial work runs on purchase orders and planned maintenance agreements rather than a quote at a kitchen table. Sending a residential crew at it would serve nobody. ## Who does it instead? **Commercial Garage Doorman**, the commercial division of the same Grimsby business behind our residential garage door partner. Their published service list covers rolling steel doors, sectional overhead doors, dock levellers and dock equipment, high-cycle spring conversions, high-speed doors and rolling shutters, planned maintenance programs, and 24/7 emergency service. They work a wider area than 905 Trades does, reaching from Hamilton and Niagara out through Mississauga, Brampton, Toronto, Vaughan, Cambridge and Brantford.

If it is a loading bay, a warehouse, a shop with a service entrance, a fire hall, a condo garage entrance or anything with a dock, that is commercial. If it is the door on the front of a house, including a triple garage on a big lot, that is residential and we can help. Two cases sit in the middle and are worth a phone call rather than a guess: a home business with a shop attached, and a small industrial unit with a single overhead door. Either side can take those, and the phone number above reaches the people who can tell you which. ## Do you get a referral fee for sending this on? No. This page is a straight hand off. 905 Trades is paid only on residential work it introduces through its own partners, and commercial enquiries go directly to Commercial Garage Doorman with nothing added. ## What about a residential garage door? That we do cover.
