Quick answer
Most Calgary homeowners should have their windows professionally cleaned twice a year — once in spring and once in fall. Homes near busy roads, construction, or with lots of trees may want quarterly cleaning. Because SudBuds rinses with pure water that leaves no mineral residue, our cleans stay clear up to 6× longer than a standard tap-water wash.
Twice a year: the Calgary standard
Two cleans a year keeps glass looking its best without overspending. Spring clears off a winter of road-salt spray, grit and hard-water deposits from snow melting on ledges. Fall removes a summer of dust, pollen and bugs so you head into winter with clear glass — see our guide to the best time of year to clean windows in Calgary.
When you should clean more often
- Busy roads & exhaust. Homes on main streets collect a film of road dust and exhaust faster — quarterly keeps it in check.
- Nearby construction. Concrete dust and silica settle on glass and can etch it if left.
- Lots of trees / pollen. Sap, pollen and bird activity mean more frequent cleaning, especially in spring.
- Lake or acreage exposure. Wind-driven dust and hard-water sprinkler overspray build up quickly.
- Listing your home. Clean windows make a measurable difference in showings and photos.
Why Calgary’s hard water matters here
Calgary has notably hard water drawn from the Bow and Elbow Rivers. When tap water dries on glass it leaves mineral spots and a faint film that grabs dust — so DIY or tap-water cleans get dirty again quickly. Our pure-water system removes those minerals first, so glass dries clean and stays clean longer. More on that in our Calgary hard water guide.
Interior vs. exterior frequency
Exterior glass faces the weather and needs the twice-a-year rhythm. Interior glass stays cleaner longer for most homes — once a year, or with your spring clean, is usually enough unless you have pets, cook often, or have young kids and fingerprints.

Frequently asked questions
How often should I get my windows cleaned in Calgary?
Twice a year — spring and fall — suits most Calgary homes. Homes near busy roads, construction or heavy trees may prefer quarterly. Pure-water cleans stay clear up to 6× longer between visits.
How often should interior windows be cleaned?
For most homes, once a year (often with the spring clean) is enough for interior glass. Homes with pets, frequent cooking or young children may want it more often.
Does cleaning windows more often save money?
Regular cleaning prevents hard-water minerals and grime from etching or permanently staining glass, which protects the windows long term — so a steady schedule can save costly restoration later.
