Commercial Window Cleaning in Toronto That Stays Streak-Free
Monthly, quarterly or seasonal window cleaning for condos, offices, retail and retirement residences across Toronto and the GTA. Interior and exterior glass, handled by trained, insured technicians under one master agreement.
What is window cleaning at Master Building Services?
TL;DR. Master Building Services provides recurring commercial window cleaning for Toronto and GTA condos, offices and retail on monthly, quarterly or seasonal plans. Trained, insured technicians clean interior and exterior glass under one master agreement with photo-verified completion reports.
Commercial window cleaning is the scheduled removal of road salt, pollen, mineral deposits and airborne grime from interior and exterior glass across a building's elevations. Glass takes the worst of GTA weather in plain view. Road salt spray films street-level windows all winter, freeze-thaw swings and wind-driven rain streak the upper elevations through spring, and the grime concentrates exactly where residents, tenants and visiting prospects look first: the entrance, the storefront, the lobby glass. Booked reactively, cleaning always lags the complaint, so the windows look their worst right when someone finally notices.
Master Building Services replaces that scramble with a recurring program. Choose monthly, quarterly or seasonal service, and trained, insured technicians keep interior and exterior glass spotless from storefronts to mid-rise elevations, with frames, sills and balcony glass added on request. The whole program runs under your one master agreement: one COI, one WSIB clearance, one monthly invoice and one account manager. Pair it with pressure washing for entrance concrete or exterior painting touch-ups on frames, and one team handles the whole envelope.

What Does a Recurring Window Cleaning Program Actually Cover?
Scope comes first. You tell us the building type, which elevations need attention and whether interior glass, frames, sills or balcony glass belong in the plan, and the quote spells all of it out so there is no ambiguity about what gets cleaned on each visit. Then you pick the rhythm: monthly where street-level grime builds fastest, quarterly for steady year-round presentation, or seasonal service timed to the GTA's salt and storm cycle.
Visits run Monday to Friday between 7am and 6pm and are scheduled around your building's traffic, so crews are not working the lobby doors at peak times. Technicians are trained and insured, with Working at Heights training for elevation work, and each visit starts with a documented hazard assessment. When the glass is done, you receive a photo-verified completion report, so you can confirm the result from your desk instead of walking every elevation. If the same visit surfaces a failed sealant joint or a cracked pane, it gets flagged for repairs and maintenance on the same report.
When Should You Book Window Cleaning in the GTA?
The GTA is hard on glass in a predictable sequence: road salt spray coats lower windows through winter, then freeze-thaw swings and wind-driven rain streak the upper elevations into spring. That makes the weeks after salt season the natural time for a full exterior clean — many buildings pair it with a pressure washing pass on the sidewalks and entrance concrete at the same time, and add a caulking and sealants check while crews are already on the elevations — with a second pass in fall before winter sets in. Seasonal plans are built around exactly that cycle; monthly and quarterly plans keep the building presentable in between.
Presentation is the other half of the case: lobby impressions drive resident satisfaction and tenant renewals, and entrance and storefront glass is the first part of that impression anyone sees. Inside, janitorial handles the floors and surfaces that frame that same impression. A recurring plan also ends the annual vendor hunt, and because MBS contracts are flat-rate and multi-year with no annual escalators, the window cleaning line in your budget stays exactly where you set it.
Why property managers choose Master.
Built for Work at Height
Glass above the ground floor is height work, and we staff it that way: Working at Heights trained technicians, a documented hazard assessment before work starts, WSIB clearance and $5M in liability coverage on a single COI that also covers exterior inspections and caulking on the same elevations.
Proof Without the Walk-Through
Every visit closes with a photo-verified completion report, so you can confirm streak-free glass on every elevation without leaving your desk.
One Agreement, Steady Pricing
Window cleaning slots into the same master service agreement as any other MBS service, with one monthly invoice and one account manager. Multi-year terms are flat-rate with no annual escalators.
Single-vendor patchwork vs the Master agreement
| Without a master contract | With Master Building Services |
|---|---|
| You chase a window cleaner every spring, then again in fall, and salt-streaked glass sits visible for weeks while you wait for a callback. | Window cleaning runs on a monthly, quarterly or seasonal rhythm built around the GTA salt and storm cycle, so glass is handled before residents notice. |
| Your window vendor carries its own COI, its own WSIB clearance and bills on its own cycle, separate from your pressure washing and caulking contractors. | Window cleaning sits inside the same master agreement as every other MBS service: one COI, one WSIB clearance, one monthly invoice. |
| Height work means chasing certificates of insurance and Working at Heights tickets from each crew before they can touch upper elevations. | Technicians are Working at Heights trained, WSIB covered and backed by $5M liability on a single COI you already have on file. |
| You walk every elevation after the crew leaves to confirm the glass is actually streak-free, or you take the vendor's word for it. | Every visit closes with a photo-verified completion report covering each elevation, so you confirm the result from your desk. |
| Annual price hikes hit your window cleaning line every renewal, and renegotiating means a fresh round of quotes. | Flat-rate multi-year terms with no annual escalators keep the window cleaning line in your budget exactly where you set it. |
| You schedule exterior inspections and window cleaning as two separate site visits, doubling the access setup. | Window cleaning can be paired with a sealant and façade check on the same visit, since the same account manager runs both scopes. |
Window Cleaning — questions property managers ask
Are your commercial window cleaning technicians insured to work above the ground floor?
Yes. Technicians are Working at Heights trained, WSIB covered and backed by $5M in liability insurance, and every job begins with a documented hazard assessment. You get one COI under the master agreement that covers window cleaning along with any other MBS service — including exterior inspections if you want a technician to check sealant and façade condition at the same time.
Will window cleaning disrupt residents or tenants in our building?
Visits are scheduled Monday to Friday between 7am and 6pm and planned around your building's traffic patterns, such as cleaning storefront glass before doors open. Interior glass is coordinated with your team in advance so lobbies and common areas are not blocked at busy times.
Do you clean interior glass, or is it exterior only?
Both are available. Standard scope covers interior and exterior glass from storefronts to mid-rise elevations, and frames, sills and balcony glass are included on request. Your quote spells out exactly which surfaces are in the plan, so there is no ambiguity on visit day.
How often should commercial building windows be cleaned in Toronto?
Plans run monthly, quarterly or seasonal, and the right frequency depends on exposure: street-level glass collects road salt spray and daily grime far faster than upper elevations. We recommend a frequency with your quote, and the plan is flexible if your building's needs change.
Do we need a separate contract just for window cleaning?
No. Window cleaning is written into the same master service agreement as everything else MBS does for your building: one COI, one WSIB clearance, one monthly invoice and one account manager. Multi-year terms are flat-rate with no annual escalators, so the price you sign is the price you keep.
