London Window Cleaning Experts

Say goodbye to pollen film, road salt residue, and seasonal mould on London windows

London’s position in southwestern Ontario gives the Forest City a window cleaning environment shaped by the city’s exceptional tree canopy and Ontario’s four distinct seasons. London is known across the province for its elm and maple-lined streets, a canopy so dense in the established neighbourhoods of Old South, Byron, Westmount, and Wortley Village that the city earned its “Forest City” nickname generations ago. This canopy is the defining character of window maintenance in London. Through April and May, elms, maples, and oaks release their pollen in a concentrated burst that coats every exterior surface in a fine film. London’s spring is also damper than many Ontario cities, the Thames River valley and London’s southwestern Ontario position mean the spring pollen season arrives with higher humidity than in the drier areas of the province, and the combination of pollen and moisture creates a film on exterior glass that bonds and does not lift with subsequent rain events.

Winter deposits are the second major maintenance challenge. London’s arterial roads, Wellington Road, Richmond Street, Wonderland Road, and the Oxford Street corridor, receive heavy municipal salting from November through March, and traffic spray carries this salt-and-grit mixture onto the exterior windows of any home within range of treated roads. London’s freeze-thaw cycle through the winter months bonds this salt residue to glass and frames, and by the time spring arrives the windows of homes near major roads are carrying a combined layer of road salt and winter grime that the first rains reveal rather than remove.

Through the damp London spring and fall, mould and algae establish on the north and east-facing window frames and sills of homes where the tree canopy keeps surfaces shaded and damp for extended periods after rain events. In the older established neighbourhoods where London’s most mature trees overhang residential lots, Old South, Wortley Village, and the riverfront corridors along the Thames, this biological growth on frames is a consistent seasonal maintenance challenge. Professional window cleaning removes both the glass deposits and the biological growth from frames as part of the standard service. We make home maintenance easy, all in one detailed visit, every window addressed. We are the professionals you can trust to protect your most valuable asset.

Window cleaning in London, Ontario — FAQs

How does Shack Shine clean windows in London?

The Shack Shine London team cleans both interior and exterior windows in a single visit. Exterior windows are washed using professional-grade cleaning solutions and squeegee techniques that remove spring pollen film, road salt residue, mould and algae from frames and sills, and organic buildup without leaving streaks. Window tracks, frames, and sills are cleaned as part of the service. Interior windows are cleaned with non-abrasive solutions safe for all glass types and coatings. Extension equipment allows every upper-storey pane to be cleaned safely. All in one detailed visit.

How often should I have my windows cleaned in London?

Twice a year is the standard for most London properties, a spring clean in May after the main pollen season, and a fall clean in October before the freeze season. The spring clean is the most impactful given the combination of winter road salt residue and spring pollen that accumulates on windows through the transition from winter to spring. Properties in Old South, Wortley Village, and the riverfront corridors under heavy mature tree canopy, where mould on frames accumulates faster, benefit most from both seasonal visits.

Why does London’s tree canopy make spring window cleaning particularly important?

London’s elm and maple-lined residential streets, the canopy that earned the city its Forest City designation, release pollen through April and May in concentrated quantities. The combination of London’s spring pollen season and the Thames Valley’s higher humidity means pollen bonds to exterior glass more firmly than in drier parts of the province. Rain events in May move the pollen film but do not fully remove it from glass surfaces. A professional clean in May, after the main pollen peak, removes the combined winter and spring accumulation cleanly.

Does road salt from London’s arterial roads affect exterior windows?

Yes. Properties near Wellington Road, Richmond Street, Wonderland Road, and the other major arterials that receive heavy municipal salting through the Ontario winter accumulate salt spray on lower-level exterior windows and frames. The salt residue bonds to glass and frames through London’s freeze-thaw cycle and becomes increasingly visible as temperatures rise in spring. A spring clean in May removes the winter’s accumulated salt film before it has the opportunity to cause lasting surface staining on frames or sills.

Does Shack Shine London also handle eavestrough cleaning and pressure washing?

Yes. The Shack Shine London team provides eavestrough cleaning and pressure washing throughout London, Old South, Byron, Westmount, Masonville, and surrounding communities. Many London homeowners book window cleaning alongside eavestrough cleaning in spring, the same pollen and organic debris that deposits on windows also fills eavestroughs through the same period. You can explore the full range of services in London.

When is the best time to book window cleaning in London?

May for the spring clean, after the main elm and maple pollen season and once the full extent of winter road salt residue is visible. October for the fall clean before the freeze season. Booking two to three weeks in advance is recommended during peak periods.

How much does window cleaning cost in London?

Because every home is unique, our pricing is calculated based on your specific property size, window count, storey height, and accessibility. A standard two-storey in Masonville or Sunningdale will be quoted differently than a larger home in Old South or Wortley Village with extensive upper-storey glazing and significant mould and pollen accumulation from decades of mature canopy overhead.
