Commercial Pressure Washing Rates in Ontario (2026)
Commercial pressure washing cost in Ontario generally lands between $0.08 and $0.30 per square foot, or $8–$20 per parking space — but the surface type, how dirty it is, and access are what set your final number. Most contractors also carry a minimum service charge of around $200–$300, because getting a crew, truck, water, and hot-water equipment to your site costs the same whether the job is small or medium.
| Surface / Service | Typical Ontario Cost (2026) | Notes |
|---|---|---|
| Parking lot | $8 – $20 / space | ≈ $0.05–$0.20 / sq ft of pavement |
| Building exterior | $0.08 – $0.30 / sq ft | Up to $0.40–$0.90 for height / heavy growth |
| Sidewalks & walkways | $0.10 – $0.30 / sq ft | Gum and stain removal adds cost |
| Concrete / loading dock | $0.15 – $0.40 / sq ft | Hot water + degreaser for oil/grease |
| Dumpster pad | $75 – $250 each | Grease + odour treatment, often quarterly |
| Drive-thru lane | $150 – $500 | Heavy grease and traffic film |
| Graffiti removal | By assessment | Surface- and product-dependent |
| Minimum service charge | $200 – $300 | Covers crew + equipment mobilization |
Because parking lots are the most common request, they're often quoted as a flat tier rather than per foot: roughly $299 for a small lot (up to 5,000 sq ft), $699 for a medium lot (5,000–15,000 sq ft), and $1,299 for a large lot (15,000+ sq ft). Heavy oil staining, gum, and tight access move you up within or beyond those tiers.
The Two Pricing Models
Like most exterior trades, pressure washing is quoted one of two ways — and knowing which you're looking at is how you compare bids fairly.
Flat / per-job pricing
Small and standard jobs are usually a flat price measured against the minimum service charge. A 4,000 sq ft lot and a 3,000 sq ft lot may be quoted nearly the same, because the mobilization cost dominates a small job. This is the simplest model and the most common for single-site work.
Per-square-foot pricing
Large surfaces — big lots, building exteriors, warehouse aprons, multi-site portfolios — are priced per square foot ($0.08–$0.30) so the rate scales with size. Add-ons like oil-stain removal, gum removal, graffiti, and working-at-heights are itemized on top. Bigger jobs earn a lower per-foot rate.
Compare like for like: a flat quote and a per-square-foot quote can describe the same job at very different headline prices. Before comparing, confirm whether hot water, degreaser/oil treatment, and any height work are included — those are the items most often left off a low quote and billed later.
What Drives the Price Up or Down
Increases Cost
- Height — anything past two storeys (lifts, working at heights)
- Heavy oil, grease, or gum
- Organic growth (algae, moss) needing soft wash + solution
- No on-site water source
- Graffiti and specialty stain removal
- Tight access or occupied-site scheduling
- Wastewater containment / environmental capture
Reduces Cost
- Larger surface (better per-foot rate)
- Light maintenance vs first-time deep clean
- Ground-level, single-storey work
- On-site water and easy access
- Recurring schedule (annual/seasonal)
- Bundling with striping or sealcoating
- Off-peak / flexible timing
Building Exteriors — Why Height Changes Everything
Building washing is priced differently from flatwork because the cost driver isn't just area — it's access and method. Ground-level storefront washing is straightforward; a three-storey office face needs a boom lift or water-fed pole system, working-at-heights certification, and more time. That's why building exteriors are quoted per project after a look at the elevation, not off a flat table.
Method matters as much as height. Many modern commercial facades — EIFS, stucco, render, vinyl, painted panel — must be cleaned with low-pressure soft washing (low pressure plus a cleaning solution) rather than high pressure, which can drive water behind cladding or strip the finish. A professional quote should specify pressure washing vs soft washing per surface. If a quote doesn't mention method on a multi-material building, ask.
How Often Should You Pressure Wash?
| Surface | Typical Frequency |
|---|---|
| Parking lots & entrances | 1–2× per year (spring + optional fall) |
| Sidewalks & storefront | 1–2× per year, more for food/retail |
| Dumpster pads & loading docks | Quarterly (grease + odour) |
| Drive-thru lanes | Quarterly to semi-annual |
| Building exterior | Annual (more on shaded/north faces) |
A spring wash after winter is the most common single service — road salt, sand, and grime that built up over the Ontario winter come off, and the property looks cared-for heading into the busy season.
Save by Bundling
Pressure washing pairs naturally with other exterior work, and bundling saves on the mobilization cost you'd otherwise pay twice:
- Wash → then stripe. Washing a parking lot right before line painting means paint bonds to clean pavement and lasts longer. Doing both in one visit is the efficient sequence.
- Wash → then sealcoat. Sealcoating requires a clean, dry surface — the wash is a required prep step anyway.
- Recurring contracts (annual or seasonal) earn better rates than one-off calls, the same way recurring cleaning does.
How to Get an Accurate Quote
Published ranges get you to a budget; a site look gets you a price. Before requesting quotes, have ready:
- Surface and area — lot size or building square footage, number of parking spaces.
- What's dirty — general grime vs oil, grease, gum, graffiti, or organic growth.
- Height and access — single vs multi-storey, lift access, on-site water.
- Surface materials — concrete/asphalt (pressure) vs stucco/EIFS/vinyl (soft wash).
- Frequency — one-time vs recurring seasonal program.
- Other exterior work — striping or sealcoating to bundle.
A professional should confirm scope on site and put the method (pressure vs soft wash), the hot-water/degreaser inclusions, and any height work in writing. Be cautious of a flat phone quote on a building exterior — elevation and material decide both the method and the price.
Frequently Asked Questions
How much does commercial pressure washing cost in Ontario?
Commercial pressure washing in Ontario generally runs $0.08–$0.30 per square foot, or $8–$20 per parking space, depending on the surface and how dirty it is. As flat jobs, a small parking lot (up to 5,000 sq ft) starts around $299, a medium lot (5,000–15,000 sq ft) around $699, and a large lot (15,000+ sq ft) around $1,299. Most contractors have a minimum service charge of about $200–$300. Building exteriors are quoted per project based on height and square footage.
Is pressure washing priced per square foot or per job?
Both. Small and standard jobs are usually quoted as a flat price against a minimum service charge ($200–$300), because mobilizing a crew and equipment costs the same whether the job is small or medium. Larger surfaces — big lots, building exteriors, warehouse aprons — are priced per square foot ($0.08–$0.30) so the rate scales fairly with size. Oil-stain removal, graffiti, and height work are added on top.
How much does it cost to pressure wash a parking lot in Ontario?
Parking lot pressure washing in Ontario typically runs $8–$20 per parking space, or roughly $0.05–$0.20 per square foot of pavement. As flat pricing that works out to about $299 for a small lot (up to 5,000 sq ft), $699 for a medium lot (5,000–15,000 sq ft), and $1,299 for a large lot (15,000+ sq ft). Heavy oil staining, gum removal, and tight access push the number up. Washing right before restriping is the most cost-effective sequence.
How much does it cost to pressure wash a building exterior?
Commercial building exterior washing in Ontario typically runs $0.08–$0.30 per square foot, rising toward $0.40–$0.90 for tough conditions, multi-storey access, or heavy organic growth. Height is the biggest cost driver — anything past two storeys needs lifts or water-fed poles and adds working-at-heights labour. Many building surfaces (EIFS, stucco, render, vinyl) need low-pressure soft washing rather than high-pressure, which a professional should specify in the quote.
How often should a commercial property be pressure washed?
Most commercial properties in Ontario benefit from pressure washing once or twice a year — typically a spring clean after winter salt and grime, and sometimes a fall clean. High-traffic parking lots, drive-thrus, and entrances may need it more often. Dumpster pads and loading docks often need quarterly attention for grease and odour. Building exteriors are usually annual unless they face heavy organic growth on the north side.
What's the difference between pressure washing and soft washing?
Pressure washing uses high-pressure water and is right for hard surfaces — concrete, asphalt, loading docks, and parking lots. Soft washing uses low pressure plus cleaning solution and is used on more delicate surfaces like stucco, EIFS, render, vinyl siding, and signage, where high pressure would cause damage. A professional matches the method to the surface; using high pressure on a soft-wash surface is a common way inexperienced operators cause expensive damage.
