Updated October 14, 2026: the earlier rate card was replaced with the prices of 7 documented power washing jobs from 2026.
Every price on this page comes from a job our crews wrote up as a case study, with the surfaces, the method and the price. Your price depends on the surface, its condition and what else is booked on the same visit, so read these as real examples, not a rate card.
Power washing cost in Toronto: what 7 documented jobs billed in 2026
Quick answer: Power washing in Toronto and the GTA cost between $150 and $400 per job on 5 DT Cleaning jobs in 2026. The two lowest, at $150 each, were a limestone patio in Etobicoke and a driveway approach, garage door and stair set downtown. The highest, $400, covered granite stairs, a walkway and a concrete motor court in North York. 2 more jobs were billed at $150 per hour.
| Job | What was washed | Billed |
|---|---|---|
| Mississauga walkway, April 2026 | Concrete walkway gone green-black with mold and algae; foam pre-treatment with a 7-minute dwell | $150 per hour |
| Toronto house exterior, April 2026 | Siding, soffit, fascia, the outside of the eavestroughs and a backyard paver patio | $150 per hour |
| Mineola, Mississauga, June 2026 | Driveway, front steps, flagstone patio and river-rock beds; 1 hour 40 minutes from setup to final rinse | $250 |
| North York, June 2026 | Granite stair runs, landing, walkway and stepping stones, plus a brushed concrete motor court | $400 flat, one line of a $1,000 visit |
| Royal York Gardens, Etobicoke, June 2026 | 800 sq ft limestone back patio, washed with a surface cleaner | $150 flat |
| Downtown Toronto rental, June 2026 | Driveway approach, garage door and a concrete stair set; ZEP pre-treatment, washed at 3,500 PSI | $150 flat, inside a $2,500 full day |
| Toronto, August 2026 | Stone patio with moss, algae and weeds in the joints; masonry chemistry, then a 3,500 PSI turbo nozzle | $170 |
Most of these jobs were booked together with another service. The $400 North York line was part of a $1,000 flat visit that also covered window cleaning and eavestrough work, and the $150 downtown line sat inside a $2,500 full day on a rental property. The service itself is described on our power washing in Toronto page, and gutter prices are on our eavestrough cleaning cost page.
Power washing cost per hour in Toronto: $150 on 2 April jobs
Quick answer: $150 per hour on 2 documented jobs in April 2026, a mold-covered walkway in Mississauga and a full house exterior in Toronto. On both, the clock started when the pressure washer was running and the prep was done, not when the crew pulled up; hose connection, equipment staging and the surface inspection were not billed. Every later job on this page was priced per job.
Our crew's estimate from that Toronto job: most two-storey homes need 2 to 3 hours for a full exterior wash, and a paver patio depends on its square footage and how packed the joints are with moss. The Mississauga write-up puts a walkway like that one at 1 to 2 hours, depending on the length of the path and how much has built up, and a full house exterior with a walkway at 3 to 4 hours.
Driveway power washing cost: $150 and $250, each with other surfaces
Quick answer: $150 flat for a driveway approach, a garage door and a concrete stair set on a downtown Toronto rental in June 2026, with ZEP pre-treatment and a 3,500 PSI wash. In Mineola, Mississauga, $250 covered a driveway, front steps, a flagstone patio and river-rock beds along both side walls, 1 hour 40 minutes from setup to final rinse.
The Mineola booking was for the driveway and the front steps. Once the crew was on the property, the homeowner added the flagstone patio behind the house and the river-rock beds along both side walls. The rocks were not billed extra: they fit inside the original ninety-minute estimate, and the chemistry was already mixed in the tank.
Patio power washing cost: $150 for limestone, $170 for stone
Quick answer: $150 flat for an 800 sq ft limestone back patio in Royal York Gardens, Etobicoke, in June 2026, and $170 for a stone patio in Toronto in August 2026 that had moss between every stone, algae across the surface and weeds in the joints. The limestone was cleaned with a surface cleaner; the stone patio got masonry chemistry first, then a 3,500 PSI turbo nozzle.
Limestone etches under a narrow high-pressure jet. On that patio our crew ran a Honda-engine pressure washer rated 3,400 PSI and 2.5 GPM through a 15-inch surface cleaner with a rotating dual-jet head, which brings the pressure on the stone face down to about 800 to 1,000 PSI.
The Toronto stone patio was an add-on: the owners, 2 months into the house, asked about it while our crew was replacing their gutter guards. Its joints had lost their sand years before, so we told them up front that a wash blows out whatever sand is left and that they should plan on re-sanding the joints afterwards.
Granite stairs in North York: $400 flat
Quick answer: $400 flat in June 2026 for the granite stair runs, landing, walkway and stepping stones of a North York home, plus its brushed concrete motor court. It was one line of a $1,000 visit that also covered windows and eavestroughs. The stairs had not been pressure washed since the house was built and carried seven years of biofilm, plus black mold on the shaded steps.
Granite gets the chemistry first and the pressure last. The crew wet the stone, applied a low-concentration sodium-hypochlorite-and-surfactant blend, let it dwell and rinsed with a fan nozzle held 12 to 18 inches from the stone, so the polish stayed. The chemistry pass took 20 minutes, the dwell 10 and rinsing the stair run about 30.
Mold, moss and algae: the chemistry goes on before the pressure
Quick answer: On the Mississauga walkway our crew applied a biodegradable foam and let it sit 7 minutes before washing; 3 to 5 minutes is enough on lightly soiled surfaces. Without that dwell, the pressure washer takes off the surface layer and leaves the roots, and the mold comes back within weeks.
That walkway had no downspout on its side of the house, so rain had been sheeting off the roof straight onto the concrete for years. Near gardens, as at the Mineola house, the crew used a low-concentration sodium-hypochlorite-and-surfactant blend, wet the plants with fresh water before starting and rinsed with plenty of fresh water at the end.
House power washing cost in Toronto: $150 per hour
Quick answer: $150 per hour for a full exterior wash on a Toronto home in April 2026: siding, soffit, fascia, the outside of the eavestroughs and a backyard paver patio. The crew sprays downward, never upward, and keeps the nozzle at least 12 inches from the surface, so water does not get under shingles, behind window frames or into siding gaps.
The paver patio took the most time on that job. The interlocking bricks had not been cleaned in years, so the crew foamed them with a biodegradable solution, let it sit five minutes and washed section by section.
Where the rinse water goes: Toronto's Sewers By-law
Quick answer: In Toronto, wastewater from outdoor washing must not reach a catch basin, the square grate on the street, even when the wash uses water alone. The City holds 2 parties responsible for wastewater leaving the property, the person hiring and the washing company, so ask any crew, ours included, where the rinse water will go before the washer starts.
"Power washing with water alone will still dislodge or dissolve contaminants from the surface being cleaned."
City of Toronto, Washing Cars & Outdoor Surfaces page
The City's page on washing cars and outdoor surfaces lists the options: let the water evaporate, re-route it away from a catch basin or contain it, or dispose of it in an indoor drain or haul it off-site with an approved hauler. Its Sewers By-law page gives the reason: "Catch basins are connected to storm sewers, which drain directly into rivers, streams and the Lake."
What moves the price, from these 7 case studies
Quick answer: Across these 7 case studies, 3 things changed the job: the surface, its condition and what else was booked on the same visit. Granite took chemistry first and low pressure, the limestone took a surface cleaner that cut the pressure on the stone, a patio with open joints was left needing re-sanding, and 5 of the 7 jobs were booked with eavestrough, window or gutter guard work.
Where these 7 jobs were done

Power washing cost in Toronto: common questions
How much does power washing or pressure washing cost in Toronto?
On 5 documented DT Cleaning jobs priced per job in 2026, power washing in Toronto and the GTA came to between $150 and $400. Two more jobs were billed at $150 per hour.
How much does it cost to power wash a driveway in Toronto?
$150 flat for a driveway approach, a garage door and a concrete stair set on a downtown Toronto rental in June 2026. In Mineola, Mississauga, $250 covered a driveway, front steps, a flagstone patio and river-rock beds.
How much does it cost to power wash a patio?
$150 flat for an 800 sq ft limestone patio in Etobicoke in June 2026, and $170 for a stone patio covered in moss and algae in Toronto in August 2026.
Do you charge by the hour or by the job?
Both, on the jobs on this page. 2 jobs in April 2026 were billed at $150 per hour, with the clock starting when the pressure washer was running and the prep was done, so hose connection, staging and the surface inspection were not billed. The 5 jobs from June onward were priced per job, all booked together with another service.
How much does it cost to power wash a house in Toronto?
$150 per hour on a Toronto house exterior in April 2026: siding, soffit, fascia, the outside of the eavestroughs and a backyard paver patio. Our crew's estimate on that job was 2 to 3 hours for a full exterior wash on most two-storey homes; the Mississauga write-up puts a house exterior with a walkway at 3 to 4 hours.
Is power washing priced per square foot?
Not on these jobs: 5 were priced per job and 2 were billed at $150 per hour. For scale, an 800 sq ft limestone patio in Etobicoke was $150 flat, and roughly 320 sq ft of granite plus 240 sq ft of brushed concrete in North York was $400 flat; the granite was the technical part of that job.
Can power washing damage stone or granite?
Yes, with the wrong pressure or nozzle. On the North York granite our crew used chemistry first and a fan nozzle 12 to 18 inches from the stone; on the Etobicoke limestone a surface cleaner brought the pressure on the stone down to about 800 to 1,000 PSI.
Will power washing take the sand out of my patio joints?
It can. On a Toronto stone patio whose joints had already lost their sand, we told the owners before starting that the wash would blow out what was left and that they should plan on re-sanding.
Do you use chemicals when power washing?
Yes, matched to the surface: masonry chemistry for moss and algae on stone, a biodegradable foam with a 7-minute dwell on a moldy walkway, a low-concentration blend near plants, and ZEP pre-treatment on a driveway approach and concrete stairs.
Is power washing the same as pressure washing?
For residential walkways, patios and driveways the two names are used interchangeably. Strictly, power washing means heated water and pressure washing means cold water; the jobs on this page used pressure washers.
Can power washing water go down the storm drain in Toronto?
No. The City of Toronto says wastewater from outdoor washing must not reach any catch basin, even when the wash uses water alone, and that both the person hiring and the washing company are responsible for it.
Can I book power washing with gutter or window cleaning?
Yes. 5 of the 7 jobs on this page were booked that way, including a $1,000 visit in North York and a $2,500 full day on a downtown rental.
