Parking lot power washing in Toronto clears the oil drips, tire marks and winter grit that make a plaza or office lot look neglected. We wash overnight with rotary surface cleaners and 200F hot water, cover every lot drain and recover the runoff with our hydrovac, so the lot is clean, open by morning and compliant.
Why Do Commercial Lots Look Worse Every Season?
Every parked car leaves something behind: oil, coolant, brake dust and rubber. Winter adds salt and sand, which grind into the surface and collect along curbs. By spring, stalls are dark with drips, drive lanes show tire tracks and curbs are crusted white. Customers and tenants read a dirty lot as a poorly managed property.
Sweeping alone does not fix this. It picks up litter and loose grit but leaves oil and residue bonded to the surface. Washing with cold water and a wand makes stripes and pushes oily water to the nearest catch basin, which is a compliance problem.
What Is Included in Parking Lot Power Washing?
- Stalls and drive lanes with rotary surface cleaners for an even finish
- Oil drip and fluid stain treatment with degreaser and hot water
- Curbs, wheel stops and islands cleaned of tire marks and salt
- Lot sidewalks and cart corrals as add-ons
- Drain protection and runoff recovery on every job

Hydrovac wastewater containment (Toronto Municipal Code 681)
Lot catch basins drain straight to the storm system. We cover them with drain mats, set berms where water would leave the site and vacuum runoff into our hydrovac tank as we wash. When basins themselves are full of winter sediment, our catch basin cleaning service extracts it on the same visit.
When Should a Lot Be Power Washed?
- Spring, after salt season, to remove grit and salt crust along curbs
- Fall, to clear leaves, oil and summer grime before freeze-up
- Before a new tenant opens or a property is listed
- After a spill, through our oil spill cleanup service
How Much Does Parking Lot Power Washing Cost?
Typical lots run $600-$1,800 and take 4-8 hours. Size, staining, curb length and how many drains need protection affect the number. The quote is written per surface, and spring and fall contracts lock the rate for 12 months.
Common Parking Lot Problems We Solve
Rows of oil drips in stalls
Every stall where a car idles collects drips. They are pre-treated with degreaser, then lifted with hot water during the main wash.
Salt and grit along curbs
Plows push salt and sand to the curbs, where it dries into a white crust. Hot water and a wand clear curb faces and gutters.
Tire marks in drive lanes
Turning tires leave black arcs in lanes and at entrances. Hot water and surface cleaners lighten them significantly.
Gum and stains on lot sidewalks
Walkways between the lot and storefronts collect gum and spills, which we treat the same way as storefront sidewalks.
What to Expect on the Night
Lots are washed section by section, starting with areas furthest from the entrances. Cones mark the active zone, catch basins are covered, oil spots are pre-treated, and rotary surface cleaners work across the stalls while the hydrovac recovers runoff. Curbs and wheel stops are detailed last. By morning the lot is dry and open, and the photo report goes to the manager.
