Calgary window cleaning with a pure-water-fed pole on the outside and a squeegee inside
Exterior glass cleaned with deionised water from a 9-metre carbon-fibre pole — no ladders, no streaks, no risk to landscaping. Interior glass cleaned with soap and a squeegee plus microfibre detail. Skylights, second-storey panes and bay windows all included. Most Calgary jobs land between $180 and $450 depending on number of panes and interior add-on.
Deionised water dries spot-free — no streaks, no soap residue on the frames
Tap water in Calgary carries calcium and magnesium minerals that leave spots when they dry on glass. Pure water — water that has been run through a deionising filter to remove every dissolved solid — does not leave anything behind. The 9-metre carbon-fibre pole pushes the pure water through a brush head that scrubs the glass, then a clean-water rinse takes everything down without needing a squeegee. Glass dries spot-free, frames stay clean, no soap residue runs down the siding.
For the interior we go old-school — a soap-and-water solution, a clean squeegee and a microfibre cloth for the edges. Glass cleaner sprays leave a film that fingerprints show up on within days; squeegee plus microfibre is the only method that stays clean for weeks. Pair window cleaning with house washing or gutter cleaning when the rinse from those services lands on the glass anyway — the windows get the streak-free finish at the end of the visit.

How a Calgary window clean runs
Four steps from screen pull to streak-free dry
Pull screens, walk the home
Screens pulled where access is needed, count of panes confirmed against the quote, interior and exterior priorities marked, skylight access route confirmed (inside or from the roof).
Exterior pole and pure water
Carbon-fibre pole extended to the highest pane, brush head scrubs while pure water rinses, glass left wet and walks dry spot-free in five minutes. Frames wiped on the lower panes where the pole does not reach.
Interior squeegee and microfibre
Soap-and-water mist on each pane, squeegee pulled in a fluid S-pattern, microfibre detail at the edges and the corners where the squeegee skips. Sills wiped clean of the runoff.
Screens, walkaround, invoice
Screens rinsed at the same time the exterior was done, replaced after the glass dries. Walkaround with you to spot anything missed before the invoice goes out.
Calgary window realities
Prairie dust, chinook humidity swings and the sprinkler-spot problem
Calgary windows pick up three layers of grime the rest of the year does not deal with. Prairie dust off the foothills lands on the glass year-round and shows up worst on the south and west elevations that face the wind. Chinook humidity swings drive condensation onto cold glass at the joins, lifting dust into water spots. And the most common Calgary window problem is the sprinkler that hits the window every morning at 6 am — hard water minerals build up in concentric rings and need a buffered acid treatment to clear.
Two washes a year is the right cadence for most Calgary homes — spring after the snowmelt dust, late summer before the leaves drop. Pair with siding cleaning on the same visit since both services tackle the front-facing curb appeal, or with house washing for the full envelope. Talk to us about a maintenance schedule if the sprinklers are the recurring problem.

Pair window cleaning with
Other envelope services on the same visit
Window cleaning pairs with anything that rinses the front of the house — siding, gutters, house wash. Combine for the cleanest curb-appeal pass.
Five questions that come up on most window quotes.
Both, priced separately. Exterior is the more common booking because the dust and pollen sit on the outside. Interior is squeegee plus microfibre, no chemicals beyond a soap-and-water mix that does not haze the glass. Most homeowners book interior alongside exterior because the contrast between a clean outside and a dirty inside is more visible than either alone.
Second-storey is reached with a pure-water-fed pole (carbon-fibre extension to 9 metres, deionised water that dries spot-free). No ladders needed for most homes, no risk to landscaping or the foot traffic below. Skylights are accessed from inside where possible, or from the roof on a soft-wash visit where we are already up there for the shingles.
Below -5°C the water freezes before the squeegee runs, so we hold winter exterior cleans for the next chinook window. Wind is fine up to about 30 km/h — past that, dust lands on the wet glass and streaks. We watch the forecast for the booked day and reschedule when the wind is forecast in the 40-plus range. The schedule has buffer to absorb a weather slip.
Most of them, yes, with a buffered acid spot treatment plus a fresh rinse. Hard water spots on Calgary glass usually come from a sprinkler hitting the window or from a hose-down at the wrong angle. Heavy long-standing deposits sometimes need two visits a week apart to fully clear. We will tell you straight whether spots are recoverable or whether the glass needs to be polished by a glazier.
A house wash rinses the glass with the same low-pressure water that rinses the siding, which gets the dust and pollen off but does not squeegee the glass dry. Some streaking is normal after a house wash unless the windows are cleaned separately. Booked together, the window clean happens after the siding dries and gets the streak-free finish — that is the bundle most clients want at the same visit.

★★★★★
Booked exterior plus interior. The pole reached the second storey without anyone on a ladder, no plants trampled. Interior was squeegee plus microfibre, no streaks even on the south windows. Two-yearly maintenance booked.

Skylight in the master bath had years of grime. They cleaned it from the roof on the same visit as the soft wash. The light coming through the bedroom is brighter than I remembered it.

Sprinkler had been hitting the dining room window for two summers. Hard water spots in concentric rings. The crew did the buffered acid treatment over two visits a week apart and the glass came back to perfect.

Bay window in the living room had nine separate panes with frames between. They squeegee'd each one and microfibred the joins. The contrast vs the dust we had been living with is unreal.
