We Fix Fences

Mississauga homes accumulate a distinctive kind of winter grime — a combination of road salt from the 400-series highways and arterial roads, wet lake-effect snow residue, and months of freeze-thaw cycling that leaves a chalky, grey film across driveways, fence bases, and lower siding panels. By mid-spring, that layer of contamination has had weeks to bond into your exterior surfaces. Professional power washing is the most efficient way to restore your home's appearance and protect the surfaces underneath.
Lean On Me serves Mississauga homeowners with commercial-grade power washing equipment and trained operators who know how to match pressure and detergent chemistry to the specific surface being cleaned. We're not a "blast everything on high pressure" operation — soft washing vinyl siding and fences, moderate pressure for wood decks, and maximum pressure for concrete driveways is how surfaces get genuinely clean without damage. Our Mississauga crews work across all neighbourhoods, from the high-density condos and townhomes near Square One to the large detached homes in Lorne Park and Mineola.
Spring exterior cleaning in Mississauga isn't just cosmetic. Algae and mould growing on shaded fence panels and north-facing deck boards actively break down wood fibres and hold moisture against surfaces that need to dry out. Removing biological growth in spring extends the life of your fence and deck, and prepares the surface properly if you're planning to re-stain or seal later in the season.
climate impact
Mississauga's location next to Lake Ontario creates elevated ambient humidity year-round compared to inland Ontario cities. This persistent moisture — combined with the city's mature tree canopy in older suburban neighbourhoods — creates conditions where algae and mould establish on shaded exterior surfaces faster than in drier climates. North-facing deck boards can develop green algae within 4–6 weeks of sustained spring moisture, especially if they weren't cleaned and sealed going into the previous fall.
Winter in Mississauga brings significant road salt application across its arterial grid — Hurontario, Dundas, Eglinton, and the QEW/Highway 403 corridors are all heavily treated throughout the salt season. Homes within one or two blocks of these roads accumulate salt spray on fences, driveways, and low siding panels throughout the winter. Salt left on concrete driveways over multiple winters causes spalling — tiny pits and flakes in the concrete surface — which power washing followed by a concrete sealer helps prevent and slow.
The high humidity of Mississauga summers also means that interlock and natural stone patios in this city green up with moss and algae faster than in drier regions, making an annual or biannual power wash particularly practical for maintaining safe, clean outdoor living areas.
common issues
- Road salt and de-icing residue on driveways, fence bases, and garage doors near major Mississauga roads
- Green algae and black mould on shaded north-facing fence panels, deck boards, and patio furniture
- Moss and algae on interlock, flagstone, and concrete patio surfaces — slip hazards in wet conditions
- Efflorescence (white chalky mineral deposits) on brick, concrete, and interlock surfaces
- Tannin staining from fallen leaves on decks and patios that went uncleaned through fall
- Exhaust and brake dust particulate accumulation on fence panels near the QEW and Highway 401 corridors

Frequently Asked Questions
Is power washing safe for my interlock driveway or patio?
Yes, when the correct technique is used. Interlock should be washed at moderate pressure — typically 1,200–1,800 PSI — with a fan tip rather than a zero-degree nozzle, which can etch or dislodge the polymeric sand between pavers. After washing interlock, we recommend reapplying polymeric sand and sealer if the joints have been disturbed. We advise clients on this before starting.
Can power washing remove years of weather staining from my fence?
Power washing removes surface contamination — algae, mould, dirt, salt residue, and loose grey fibres from weathered wood. It won't reverse deep UV graying or bring back original wood colour. For a full colour restoration, fence washing followed by a semi-transparent stain or solid wood stain is the complete solution.
How often should I power wash in Mississauga?
Most Mississauga homeowners benefit from an annual spring wash after the salt season ends. Properties near Lake Ontario, major roads, or with significant tree coverage may benefit from a second wash in fall before winter sets in.
Do you offer soft washing for vinyl siding?
Yes. Vinyl siding requires low-pressure soft washing — typically under 600 PSI — combined with a biodegradable detergent designed to break down algae and mould chemically rather than by force. High pressure on vinyl siding can force water behind panels and cause interior moisture damage. We always soft-wash siding.
How long does power washing take for a typical Mississauga home?
A full exterior package — driveway, deck, and fence — typically takes 3–5 hours for a standard Mississauga detached home. Larger properties or heavily contaminated surfaces take longer. We'll provide a time estimate when we quote.
