What Our GTA Clients Say
Heritage Unionville to Tech Corridor: Window Cleaning in Markham
Markham sits at an interesting intersection of old and new. Main Street Unionville has some of York Region’s oldest commercial buildings - 1850s brick storefronts with original deep-sill windows that need careful cleaning technique. Five kilometres east, Cornell and Cathedraltown are less than 20 years old, with large-format windows and composite cladding that needs a completely different approach. DT Cleaning crews work both ends of that spectrum regularly.
The Rouge River runs north-south through Markham, creating conservation land that borders many residential properties. We use only Health Canada-approved biodegradable solutions near these areas, and our purified-water systems mean no chemical agents enter soil or runoff. Homeowners searching for window cleaning near me in Markham - whether in heritage Unionville or the newer Cornell and Wismer communities - get the same purified-water result without risking the conservation corridors nearby.
For eavestroughs, Markham’s mix of mature trees in older neighbourhoods and open-field wind exposure in newer subdivisions means debris accumulation varies widely. Unionville properties near the 16th Avenue canopy need autumn cleaning most critically; Cornell properties catch windblown debris more than leaf fall and benefit from a post-storm check.
