Lake Bonavista Glass Has 50 Years of Hard Water Build-Up. We Cut Through It.
Calgary's first lake community was built in the 1970s — beautiful homes, mature trees, lake views. But fifty years of sprinkler overspray, mineral-heavy lake humidity, and oxidized window frames need a cleaner who treats the cause, not just the surface.

We Clean What Spray-And-Squeegee Leaves Behind
Most Lake Bonavista homes were built between 1968 and 1985. That's older vinyl frames, original or single-replaced glass, and decades of mineral build-up from lake humidity and sprinkler overspray. A generic window clean removes loose dirt but leaves the etched mineral spots behind — they're still there, just harder to see. We treat with a mild acid-wash technique that lifts the deposits without damaging the seal or the frame.

- Lake-side glass: extra rinse to prevent re-spotting
- Sills, tracks, and screens cleaned with the panes
Lake Bonavista's glass needs more than a squeegee
Lake Bonavista was Calgary's first lake community, built around the 52-acre lake in 1968. The original homes — many still owned by the families that bought them new — were built with the window technology of the era: single-pane glass, vinyl frames, aluminum tracks. Even renovated homes often kept the original frames while upgrading just the panes.
Fifty-plus years of lake humidity does something to glass that drier neighborhoods don't deal with. The lake throws mineral-laden mist into the air during summer; sprinklers from manicured Bonavista lawns hit windows daily; the freeze-thaw cycle from Bow River fog burns calcium into the glass surface. The result: windows that look hazy even after a normal cleaning, with permanent-looking spots in a frosted pattern at sill height.
We've treated this exact problem in homes across Lake Bonavista Drive SE, near Trico Centre, and the boat-access cul-de-sacs along the south shore. The fix is a calibrated acid-wash applied with non-scratch pads, neutralized within 60 seconds, and rinsed with pure water. It removes 5-15 years of mineral build-up in a single visit. After that, twice-yearly maintenance cleaning is enough to keep the glass clear.
Typical Lake Bonavista home: 2,000-3,200 sq ft, 25-45 window panes, lake-side or interior lot. Standard cleans run $180–$280; hard-water restoration adds $50–$150 depending on the condition. Schools we coordinate around: Lake Bonavista Elementary, Andrew Sibbald.

My windows look hazy even after cleaning. What's that?
Almost always mineral build-up from years of sprinkler overspray and lake humidity. Standard washing removes the loose dirt but leaves the etched calcium behind. We use a calibrated acid-wash technique that dissolves the deposits without damaging the seal. Most Lake Bonavista homes see a dramatic difference after one treatment.
Are your products safe for the lake and our plants?
Yes. The neutralizing wash and the rinse water we use are biodegradable and pH-neutral once they hit the soil. We rinse landscaping before and after exterior work. No concern for koi, lake fish, or sprinkler-fed lawns.
How long does it take?
Most Lake Bonavista homes are 2-4 hours including interior. A hard water restoration adds 30-60 minutes. We finish before lunch on most jobs that start at 8:30 AM.
When should we book?
Twice a year works for most Lake Bonavista homes — early May (after the snow melt and the first heavy sprinkler week) and late September (before fall leaves). Lake-side homes benefit from a third clean in mid-August because the lake humidity peaks in July-August.
