Honest pricing for Markham driveways, walkways, patios, siding, and fences. Interlock re-sanding available. Serving Unionville, Cornell, Markham Village, and Stouffville.
Markham has some of the nicest residential properties in the GTA. From established streets in Markham Village with mature trees and older concrete, to brand new builds in Cornell and Box Grove with fresh interlock and stone. Both need cleaning, just for different reasons. Here's what it costs.
Markham lots tend to run larger than Scarborough, so pricing is slightly higher for the bigger driveways and wider frontages that are standard here.
| Surface | Typical Size | Price Range |
|---|---|---|
| Driveway (2-car, concrete) | 300 to 500 sq ft | $149 to $219 |
| Driveway (3-car or large) | 500 to 900 sq ft | $219 to $329 |
| Interlock driveway | 300 to 700 sq ft | $219 to $379 |
| Interlock re-sanding (add-on) | 300 to 700 sq ft | $75 to $175 |
| Front walkway + steps | 50 to 200 sq ft | $99 to $169 |
| Patio (concrete or stone) | 100 to 400 sq ft | $129 to $249 |
| Deck (wood or composite) | 100 to 350 sq ft | $149 to $279 |
| Fence (wood or vinyl) | 50 to 200 linear ft | $149 to $349 |
| House siding (soft wash) | 1,800 to 3,000 sq ft | $349 to $549 |
| Full exterior package | Driveway + walkway + patio | $399 to $649 |
Every Toronto-area winter does a number on outdoor surfaces. Markham gets it all: road salt from Highway 7 and 16th Avenue, de-icer chemicals from commercial parking lots that get tracked home, sand from municipal plowing, and months of freeze-thaw cycles that push grime deeper into concrete and grout.
Oil stains are especially common on Markham driveways. Cold morning starts in December through March mean engine drips that sit on cold concrete for weeks before anyone notices. By spring, those stains are set in.
For newer Markham developments, there's another issue entirely: construction dust. If your home was built in the last three to five years, or if there's active construction on your street, you probably have a fine layer of cement dust, drywall dust, and gravel grit on your siding, windows, and driveway. A soft wash for the siding and pressure wash for hard surfaces clears it all in one visit.
Markham has more interlock driveways and walkways per capita than almost anywhere in the GTA. Interlock looks stunning when the pavers are clean and the joints are tight. But pressure washing displaces the sand between pavers. That's not a flaw in the process. It's just how it works.
That's why we offer interlock re-sanding as an add-on. After washing, we sweep new polymeric sand into the joints, mist it to activate, and let it cure. The sand hardens and prevents weeds, ant hills, and paver movement. It extends the life of your interlock and keeps it looking sharp for the full season.
| Re-Sanding Service | Area | Price |
|---|---|---|
| Small walkway or front step area | Under 100 sq ft | $75 to $100 |
| Standard driveway | 300 to 500 sq ft | $100 to $150 |
| Large driveway or driveway + walkway | 500 to 700 sq ft | $150 to $175 |
Homes in Cornell, Box Grove, Wismer, and Cathedraltown are often under ten years old. The interlock is in good shape, but construction dust from nearby building sites coats everything. Siding gets a grey film. Driveways pick up cement splatter and gravel marks. A combination of soft wash (siding) and pressure wash (driveway, walkway) brings a newer home back to showroom condition. Full exterior packages for newer Markham homes run $399 to $649.
Markham Village, Unionville, and older parts of the 16th Avenue corridor have homes with poured concrete driveways that are 20 to 30 years old. These surfaces show tire marks, rust stains from lawn furniture, oil spots, and years of embedded grime. They clean up beautifully with proper technique and degreaser pretreatment. The transformation is dramatic. $149 to $329 depending on size and condition.
Markham properties, especially in Berczy and Rouge River Estates, often have wider and longer driveways than you'd find in Scarborough. Some homes have double-width driveways with room for four or five cars. Pricing scales with square footage, but you still get better value per square foot on larger jobs. We quote per property, not from a generic chart.
Markham backyards tend to be generous. That also means more fence to maintain. Wood fences grey out and develop mildew within a few seasons. Vinyl fences get green algae on the north-facing side. We soft wash both types and bring back the original colour. $149 to $349 depending on length and material.

Slightly higher on average, because Markham lots and driveways tend to be bigger. A 2-car driveway costs about the same. But a large Markham driveway (600 to 900 sq ft) costs more simply because there's more surface to clean. We quote per property, so you'll know exactly what your job costs before we start.
Yes. We use 1,500 to 2,000 PSI on interlock, which is strong enough to clean the surface without blowing out joint sand the way a 3,000 PSI blast would. Some sand displacement is normal and expected. That's why we recommend re-sanding after every interlock wash.
Book a full exterior package. We soft wash the siding to remove the dust film without scratching or damaging the finish. Then we pressure wash the driveway and walkways. One visit handles everything, and the difference is night and day. This is one of our most requested services in newer Markham neighbourhoods.
