Window Cleaning Services in Thornhill

Thornhill lies in two cities: Vaughan west of Yonge Street and Markham east of it. In the 2021 Census, more than half of the homes in each city as a whole were single-detached houses. So we start with houses.

Houses

We mostly wash the outside glass of a house with a water-fed pole and four-stage filtered water. Some windows we clean from a ladder with a squeegee.

Townhomes and Semis

We clean a townhome or a semi the way we clean a detached house, mostly with the water-fed pole.

Condo Buildings

Below 7 storeys, water-fed poles do most of the work. On taller buildings, we use rope access and bosun chairs (seats that hang from a rope).

Stores and Offices

Our crews also clean the windows of stores, offices and restaurants. They plan the work to keep disruption to your business low.

Homeowners can also have the inside glass, the screens and the tracks cleaned on request. We have pages on high-rise window cleaning and post-construction cleaning services.

How a Water-Fed Pole Works

The water first runs through a four-stage filter. It takes out the dissolved solids, down to 0 ppm (parts per million), so nothing is left to dry as spots. We scrub the glass with the brush on the end of the pole and rinse it with the same pure water.

Outwash has over 15 years of experience, so we know which method suits which building. For more, see our main page on window cleaning services in Toronto.

Do you ever clean windows by hand?

Yes. In condos and tight spaces, we clean the glass by hand with squeegees. After construction, we usually clean it by hand too, with a scraper and a squeegee.

How do I get a price for window cleaning in Thornhill?

Fill out the quote form on this page, or call us. The quote is free. The price depends on the building, so we quote each job.

Does the water-fed pole reach the second floor?

Yes. On buildings up to 6 storeys, we mostly use water-fed poles.

How often should windows be cleaned?

We recommend cleaning them at least twice a year, once in spring and once in fall. Storefronts and other busy buildings usually need more frequent cleaning.

Is Outwash insured?

Yes. Outwash carries $5 million in liability insurance and WSIB coverage, and all staff hold Working at Heights certification.
