Window Cleaning in Calgary

Window cleaning is fairly universal as a trade, but the soiling here has a local character worth understanding, because it determines when the work is worth booking. Winter road treatment is the main driver. Five months of salt, brine and traction gravel gets thrown up onto ground-floor and street-facing glass, and it does not simply rinse off; salt bonds to glass and leaves a haze that survives an ordinary wash.

Then there is chinook cycling. Repeated freeze-thaw swings pull moisture across the glass surface again and again, and each cycle leaves behind mineral deposits from whatever was dissolved in it. That is the origin of the hard-water spotting that makes windows look permanently cloudy even after cleaning, particularly on south and west elevations that catch the temperature swings hardest.

Both are why the standard Calgary pattern is a proper clean in spring once the salt season has ended, and a second before winter for homes and businesses where appearance matters year-round. Spring is the one that changes how a house looks. Booking it early matters, because everyone wants the same three weeks in May.

One caution worth stating plainly. Mineral deposits that have been left on glass for years can etch into the surface, at which point they are damage rather than dirt and no amount of cleaning will remove them. We will tell you during the quote if we can see that on your glass, rather than clean the windows and let you discover afterwards that the cloudiness is still there.

If your windows are new, this is not the service you want. Construction glass carries manufacturer stickers and adhesive, paint and stain overspray, silicone and caulk smears, stucco and mortar splatter, and fine abrasive grit sitting on the surface. Cleaning it like ordinary glass drags that grit across the pane and scratches it, and scratched new glass is a warranty conversation with the window supplier that nobody wins quickly.

It needs a different method: careful flooding and lubrication first so nothing is dragged dry, controlled scraping at the correct angle only where the glass tolerates it, solvent work for silicone and adhesive, and awareness of which coated and tempered glass must not be scraped at all. That work is scoped on our post-construction window cleaning page, and it is a service we have run for Calgary builders for years.

The practical rule: if the building or the windows are new, or a renovation has just finished, book the construction version. If the glass has been in place and simply needs cleaning, this is the right page. If you are not sure, describe the situation when you call and we will put you on the correct one, they are priced differently because the work genuinely is different.

Most Calgary residential window cleaning is reachable safely from the ground with water-fed poles or from ladders at moderate height, which covers the great majority of two-storey homes. Our crews are insured and WCB-covered, which matters more on this service than most, because window work is the one where an uninsured contractor falling on your property becomes your problem.

Where a property genuinely requires rope access, swing stage or lift equipment, typically mid-rise and high-rise commercial, that is specialised high-access work with its own certification and equipment requirements, and we will tell you that rather than improvise. We would rather refer a job than send a crew up something they should not be on.

For commercial clients, storefront and entrance glass is usually best run on a recurring cycle rather than booked reactively, because entrance glass is the first thing a customer forms an opinion from and it degrades within days rather than months. That can be folded into a commercial cleaning contract so it is scheduled and invoiced with everything else rather than remembered separately.
