Transparency: MANTLE serves King City and is on this list. Honest: King City is at the edge of our service area and requires advance booking for travel logistics.
King City is where Toronto's wealthiest go for space. Multi-acre estates, equestrian properties, and homes that measure in the thousands of square feet line the roads north of the 400-series highways. Window cleaning here isn't a "quick in-and-out" — it's a full-day commitment that requires the right equipment, enough time, and respect for the property.

Well water + sprinkler devastation: King City's private wells produce water at 200-300+ mg/L TDS — among the hardest in the GTA. When sprinkler systems use this water, every droplet that hits a window leaves a mineral deposit. Over one summer, sprinkler overspray creates white scale buildup that standard cleaning CANNOT remove — it's chemically bonded to the glass. ClearCoat™ purified water (0-5 TDS) dissolves these deposits. If your windows have white spotting on the first floor near sprinkler zones, tell your cleaner about the well water BEFORE they quote.
Equestrian property dust: Arena sand, hay particulate, and agricultural dust create a unique grime cocktail on horse property windows. This dust is abrasive — wiping dry scratches glass. Professional pre-soaking with purified water softens and lifts agricultural particulate safely. If you're in horse country (Keele-Dufferin corridor, King-Vaughan Road area), mention it when booking.
