Serving Markham's Diverse Properties

Markham is one of the most architecturally diverse cities in the GTA. Within a short drive you can go from the heritage brick storefronts of Unionville's Main Street to the sleek glass-and-steel condominiums rising along Highway 7 near the Markham Centre district. Each style presents its own window and gutter cleaning requirements, and our team is equipped to handle them all. In Unionville's historic core, we work carefully around century-old window trims and decorative mouldings, using pure water at low volume to avoid saturating aged wood or loosening heritage paint.

The newer communities of Cornell, Wismer, and Box Grove represent Markham's suburban expansion — thousands of homes built in the 2000s and 2010s with large bay windows, transoms above entryways, and multi-level rooflines that create challenging gutter configurations. These developments were often built on former agricultural land, and the young landscaping means less leaf litter in gutters but more wind-blown dust, construction residue, and granule wash-off from new asphalt shingles. We see a lot of dark streaking on windows facing prevailing westerly winds in these areas.

Cachet, Angus Glen, Berczy Village, Markham Village, and the Langstaff corridor include homes, storefronts, offices, and multi-unit properties. Serv1sland assesses pane count, skylights, exterior height, gutter access, tree debris, and property-management rules, with exterior work limited to suitable low-rise scopes.
