Transparency: MANTLE is based in Scarborough and serves Thorncrest Village. Honest about gaps.
Thorncrest Village is what happens when you take 1-acre minimum lots, plant them with trees in 1945, and let 80 years of growth create a private forest of estate homes. This is not a neighbourhood you stumble into — there's one way in, winding roads, no through-traffic, and homes set so far back from the road you sometimes can't see them. For window cleaning, Thorncrest is the highest-ticket residential work in Etobicoke: massive homes, period glass, and homeowners who expect perfection.

Heritage glass requires pH-neutral cleaning: Many Thorncrest Village homes retain original 1945-1960 glass — including leaded panels, beveled accents, and early thermopane units. These period glass types have surface compositions that react differently to modern cleaning chemicals. Alkaline cleaners (pH 10+) can cloud leaded glass permanently; acidic cleaners (pH 3-) can etch beveled edges. ClearCoat™ purified water is chemically neutral (pH 7.0, 0 TDS) — the only cleaning method recommended by heritage conservators for period glass. If a company shows up with a spray bottle of blue liquid, ask them to stop.
Estate scheduling and access: Thorncrest Village homes are private — many have gates, intercoms, long driveways, and specific access requirements. MANTLE offers pre-scheduled estate service: we confirm the date 48 hours in advance, arrive within a 30-minute window (not "between 9 and 5"), and our team carries photo ID and branded uniforms. For Thorncrest homeowners who are away during service: we photograph before/after every window and send a completion report by text within 1 hour of finishing.
