Residential and commercial window cleaning use the same basic skills, but almost everything around them changes: scale, access, insurance, paperwork and timing. Here is what actually differs, how to tell which service you need, and what to ask for either one.

Scale changes the whole job
A house has dozens of windows, and a crew can finish it in a visit. A commercial building has hundreds of panes across storefronts, entrances, office glass and upper floors, and the work is planned as a route, not a single visit. Residential work is about detail: screens, tracks, sills, divided panes and garden beds. Commercial work is about efficiency, consistency and coverage, with a tidy result across a long facade.
The client is different too. A homeowner decides alone. A commercial job usually involves a building owner, a property manager, tenants and sometimes a condo board, each with a say in timing and scope. That means more communication before the work starts, and more need for a written scope that everyone can point to.
Consistency matters more in commercial work as well. A storefront that is spotless on Monday and streaked by Friday reflects on the business behind it, so contractors plan repeat visits around foot traffic, weather and the season, instead of treating each visit as a one-off.
Access and safety: ladders, poles, lifts and ropes
Homes are usually reached with ladders that have a standoff, and poles from the ground. Commercial buildings add storefronts that need long-handled tools, mid-rise glass that needs lifts or rope systems, and entrances with foot traffic and vehicles nearby.
Anyone working at height in Ontario should have the right training and fall protection. Ontario has Working at Heights training for workers, and it is a fair thing to ask a commercial contractor about. It is not a homeowner requirement, but a home with second-storey glass benefits from a company that takes it seriously.

Insurance, paperwork and contracts
Commercial clients tend to ask for paperwork that homeowners rarely see.
- Proof of liability insurance, often with the property owner or manager named on the certificate.
- Proof of WSIB coverage for anyone on site.
- A written scope, listing which glass, which sides and how often.
- A schedule, with access arrangements and a named contact.
- Invoicing for a business, such as monthly or per-visit billing.
The certificate naming the owner or manager matters because it shows who is covered if something is damaged or someone is hurt on the property. Homeowners can ask for the same items. A company that supplies them without fuss is telling you something useful, and one that stalls is telling you something too.
Glass, frames and finishes
Storefronts and offices have large panes in anodized aluminum frames, often with tinted or reflective glass. Commercial dirt is different too: traffic film, handprints on entrance doors, salt tracked in and splashed up in winter, and construction dust near busy sites.
Homes have divided-pane windows, screens, sliding-door tracks, skylights and sprinkler-spotted glass. A home also has finishes that punish rough treatment, such as painted wood sills and vinyl frames. The techniques are related, but the priorities are not the same.
Scheduling and disruption
Commercial work often happens before opening or after closing, so customers and staff are not in the way, and many businesses schedule visits on a regular cycle so the glass never looks neglected. Crews use signs and cones, keep entrances clear and plan around deliveries.
Residential visits happen in daytime, and many do not need anyone home if the crew has access to the yard. Weather reschedules are common at both. Ask any company how it handles rain and missed visits, and who to call if something goes wrong. On a commercial job, also ask how tenants will be told, and where the crew will park and set up.
Which one do you need?
- A single-family home, semi or townhouse: residential window cleaning.
- A shop, office, restaurant or industrial unit: commercial window cleaning.
- A multi-unit building or condo corporation: usually commercial, since access, insurance and contracts follow the building.
- A home-based business: ask the company how it prices mixed jobs.
D&D Home Services offers both. Residential window cleaning starts from $125 for typical Kitchener-Waterloo homes. Commercial jobs have no published starting price, and quotes are free and confirmed in writing.
