Transparency: MANTLE is based in Scarborough and serves Hoggs Hollow. Honest about gaps.
Hoggs Hollow is one of Toronto's best-kept secrets — a valley-floor community of estate homes tucked into the Don River ravine, just south of York Mills Road. The microclimate here is unlike anywhere else in the city: 30-40% higher humidity, persistent morning fog, 100-year tree canopy, and direct river proximity. Every exterior surface in Hoggs Hollow works harder against moisture than virtually any other neighbourhood in the GTA.

Valley floor microclimate: Hoggs Hollow sits 20-30 metres below the surrounding plateau (York Mills to the north, Forest Hill to the south). Cold air pools in the valley overnight, creating morning fog and dew that keeps glass wet until 10-11 AM — even on sunny days. This daily wet-dry cycle deposits mineral film 50-100x faster than plateau neighbourhoods. ClearCoat™ purified water (0 TDS) is the only solution that doesn't ADD minerals while cleaning. Standard tap water (120-140 TDS) leaves 120-140 parts per million of calcium and magnesium on glass with every wash.
Heritage glass care: Several Hoggs Hollow properties have heritage-designated elements — original wavy glass, leaded windows, stained glass panels, and custom millwork. These cannot be cleaned with ammonia, vinegar, or any chemical solution (chemicals degrade lead came, etch antique glass, and damage wood finish). ClearCoat™ purified water is chemically neutral (pH 7.0, 0 TDS) — it cleans through pure dissolution without any chemical reaction. This is the only cleaning method approved by heritage conservators for original glass.
