Window Cleaning Markham
- 500+ Five-Star Reviews
A 5.0 rating across more than 500 Google reviews since we started in 2023. Two permanent crews work the GTA six days a week, which is why the technician who cleaned your windows last spring is usually the one who comes back.
- Highly-Trained Team
All technicians are certified in Working at Heights and WHMIS safety protocols, which covers ladder work, fall protection, and the handling of cleaning solutions. We keep that training current.
- Our Guarantees
If it rains within 3 days of your window cleaning, we come back and re-clean at no charge. If our crew arrives after the promised arrival window, the visit is free. Our team carries CAD $2 million in general liability coverage and WSIB, so your property is protected while we work.

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 biodegradable, phosphate-free solutions near these areas, and our purified-water systems need no detergent on glass at all. 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.
