If you've lived through a Toronto winter, you know what your driveway looks like by April: salt-stained, oil-spotted, and grey instead of whatever colour it used to be. Pressure washing brings it back — but how much does it cost, when should you do it, and is it worth it?
How Much Does Driveway Pressure Washing Cost in Toronto?
Here's what you'll actually pay in the GTA:
| Driveway Type | Size | Price Range |
|---|---|---|
| Concrete (2-car) | ~350 sq ft | $199 – $299 |
| Concrete (3-car / long) | ~500 sq ft | $299 – $399 |
| Interlock pavers (2-car) | ~350 sq ft | $249 – $399 |
| Interlock pavers (3-car) | ~500 sq ft | $349 – $449 |
| Asphalt | ~350 sq ft | $199 – $279 |
| Exposed aggregate | ~350 sq ft | $229 – $329 |
Why Interlock Costs More
Interlock driveways are the most common premium driveway in the GTA — and the most time-consuming to pressure wash. The joints between pavers trap weeds, moss, dirt, and ant hills. Cleaning between every joint takes 40-60% longer than a flat concrete surface. That's why interlock always costs more.
After cleaning, interlock driveways should be re-sanded (polymeric sand in the joints) and ideally sealed. This isn't included in basic pressure washing but adds $3-$5 per square foot and makes the results last 2-3x longer.
What's Happening to Your Driveway Every Winter
Toronto uses approximately 130,000 tonnes of road salt per winter. That salt, combined with road grime, brake dust, and engine oil, gets tracked onto your driveway from October through April. Here's what's building up:
- Road salt (sodium chloride) — white film that etches into concrete over time
- Calcium chloride (de-icer) — used on walkways, leaves sticky residue that attracts more dirt
- Oil and transmission fluid — black spots from every vehicle that parks on it
- Tire marks — rubber compound transfer, especially in hot weather
- Organic stains — leaf tannins, tree sap, bird droppings, algae and moss in shaded spots
- Construction dust — if there's development within 2km, fine concrete/drywall dust settles everywhere
Left untreated, these deposits don't just look bad — they accelerate concrete deterioration. Salt causes spalling (surface flaking), and organic growth holds moisture that freezes and cracks surfaces.
When to Pressure Wash Your Driveway
| Timing | Verdict | Why |
|---|---|---|
| Mid-April to June | ✅ Best | Salt is fully dry, temps above 10°C, cleaning solution works well |
| July to September | ✅ Good | Warm weather, fast drying. Best for sealing after |
| October | ⚠️ Okay | Last chance before freeze. Don't seal — too cold to cure |
| November to March | ❌ No | Water freezes in cracks. Freeze-thaw damage. Wait for spring |
Concrete vs. Interlock vs. Asphalt: Different Approaches
Concrete Driveways
The most forgiving surface. Handles 3,000-4,000 PSI without damage. Use a surface cleaner attachment (the spinning disc) for even results without zebra stripes. Stubborn oil stains need pre-treatment with degreaser.
Interlock Pavers
Use 2,500-3,000 PSI at a wider fan angle. Focus on joints. Don't use a turbo nozzle — it'll blast polymeric sand out of joints and can chip paver edges. After cleaning, re-sand joints within 48 hours to prevent weed regrowth and ant re-colonization.
Asphalt
Lower pressure (1,500-2,000 PSI). Asphalt is softer than concrete — high pressure loosens aggregate and shortens driveway life. Use a wider fan angle and keep the nozzle further back. Hot water helps dissolve oil but isn't necessary for general cleaning.
Exposed Aggregate
Medium pressure (2,000-2,500 PSI). The raised stone surface is durable but the resin/cement between stones can erode with too much pressure. Use a surface cleaner, not a direct nozzle.
Should You DIY or Hire a Pro?
DIY driveway pressure washing
- Rental cost: $50-$90/day for a gas pressure washer (Home Depot, Sunbelt)
- Your time: 2-4 hours including pickup, setup, cleaning, and return
- Risk: Etching lines, uneven cleaning, spraying dirty water onto siding/garage door
- Best for: Simple concrete driveways with light staining
Professional driveway pressure washing
- Cost: $199-$449 depending on surface and size
- Your time: Zero
- Advantages: Right PSI for your surface, even results, pre-treatment for stains, no cleanup, insured
- Best for: Interlock, heavily stained concrete, pre-listing prep, anyone who values their Saturday
How to Make Results Last Longer
- Seal your driveway after cleaning — concrete sealer ($150-$300 DIY) or interlock sealer ($3-$5/sqft pro) extends results by 2-3x
- Fix oil leaks — that fresh clean driveway will re-stain in weeks if your car drips
- Redirect downspouts — gutter overflow onto driveways causes algae growth and staining
- Sweep monthly — removing organic debris prevents staining and moss/weed growth in interlock joints
- Treat spots immediately — oil stains set within 24-48 hours. Cat litter + degreaser for fresh spills
Before & After: What to Expect
A properly pressure-washed driveway looks dramatically different. The most common reaction from customers: "I forgot it was this colour."
Concrete goes from grey-brown back to light grey. Interlock pavers regain their original red, grey, or charcoal colour. The visual difference is one of the highest-impact curb appeal improvements you can make — and one of the cheapest. For context, a new driveway costs $5,000-$15,000+. Pressure washing costs $199-$449 and makes it look new.
Selling Your Home? This Is a Must
Real estate agents consistently rank driveway cleaning as one of the top 5 pre-listing improvements. A clean driveway is the first thing buyers see — it sets the tone for the entire showing.

Frequently Asked Questions
How much does driveway pressure washing cost in Toronto?

When should I pressure wash my driveway?
Mid-April through June is ideal — after winter salt dries and before summer entertaining. Wait for consistent 10°C+ temperatures.
Will pressure washing damage interlock?
Not with proper technique. The right PSI (2,500-3,000), correct nozzle (no turbo), and re-sanding afterward keeps pavers perfect.
How long does a clean driveway last?
6-12 months for unsealed concrete. 12-18 months for sealed interlock. Monthly sweeping extends results.
Can I pressure wash my own driveway?
Yes — similar to window cleaning, simple concrete driveways are DIY-friendly. Interlock and heavily stained surfaces are better left to pros.
