Transparency: MANTLE serves Unionville and is on this list. Honest about gaps.
Unionville is Markham's crown jewel — a heritage village with charm that most Toronto suburbs can only dream of. Main Street Unionville draws visitors from across the GTA, but behind the shops are some of York Region's most desirable residential streets. From heritage 1850s homes to modern 5,000+ sq ft estates on Carlton Road, Unionville demands window cleaning that matches its character.

Toogood Pond effect: Homes near Toogood Pond (the heart of Unionville) face increased humidity from the pond and surrounding wetland. This creates two challenges: (1) Faster algae growth on north-facing glass — green film appears within months. (2) Condensation patterns — more frequent morning fog on exterior glass. ClearCoat™ purified water leaves no mineral base for algae to grip, extending clean time by 40-60% vs standard tap water cleaning.
Carlton Road estates: The stretch from Kennedy to McCowan along Carlton Road features some of Markham's grandest homes — 5,000-8,000+ sq ft with 40-60+ windows. These are full-day jobs. If a company quotes you "2 hours" for a Carlton Road estate, they're cutting corners. A proper clean with tracks, sills, and screens takes 6-8 hours for homes this size.
