Why Markham Windows Get Dirty Faster
Markham's position northeast of Toronto puts it in the path of prevailing winds that carry dust and pollen from the agricultural land east of the city. In spring, fields being tilled in the Stouffville and Uxbridge area generate fine particulate that settles on windows across Cornell, Wismer, and Angus Glen. Combined with the heavy tree pollen from the Rouge River valley, Markham homes accumulate grime faster than you might expect for a suburban city.
Construction is another major factor. Markham has been one of the GTA's most active development areas, with ongoing projects along Highway 7, in Markham Centre, and throughout the new communities in the north. Construction dust — a fine mix of concrete, dryite, and soil — embeds in window glass and creates a hazy film that regular rain will not wash away. If your home is within a few blocks of an active construction site, professional cleaning every 3 to 4 months is worth considering until the project is complete.
The diverse housing stock in Markham also means different cleaning requirements. Unionville's heritage storefronts and century homes have single-pane and leaded glass that requires hand cleaning — you cannot use high-pressure systems on these windows. Meanwhile, the executive homes in Cachet and Angus Glen have two and three storey facades with oversized windows that need water-fed pole equipment to reach safely.
Our Cleaning Process
Walkthrough and Quote Confirmation
We assess your windows, note any special requirements (screens, storm windows, heritage glass), and confirm the scope before starting.
Screen Removal and Wash
All accessible screens are removed, hand-washed, and set to dry while we clean the glass.
Exterior Clean with Deionized Water
Our water-fed pole system uses purified deionized water that dries streak-free. Reaches up to 65 feet — no ladders needed for most Markham homes.
Frame, Sill, and Track Detail
We clean the entire window — not just the glass. Frames, sills, and tracks are wiped down and cleared of debris.
Photo Report
You receive before and after photos of every window section documenting the work.
