⚠️ Markham homeowners: interlock driveways need special care. Over 60% of Markham homes built after 2000 have interlock driveways. Wrong pressure (3,000+ PSI instead of 1,200-1,800) destroys polymeric sand and damages paver surfaces. Repair cost: $3,000-$8,000. Always ask your pressure washer about their interlock process before booking. Full interlock safety guide →

The Markham interlock test: Before booking any pressure washing company for your interlock driveway, ask: "What PSI do you use on interlock?" If the answer is above 2,000 or they don't know, keep looking. Then ask: "Do you re-apply polymeric sand?" If no, keep looking. These two questions eliminate 80% of companies that will damage your driveway. Full interlock guide →

How to Choose

  1. Know your surface. Concrete, interlock, and vinyl siding all require different pressure levels. A company that uses one PSI for everything will damage something.
  2. Ask about soft washing. For house siding, stucco, and heritage brick, soft wash (under 1,000 PSI) is the only safe method. Method comparison →
  3. Get inclusive quotes. "Driveway from $199" often excludes walkways, patio, and front step — which can double the price.
  4. Check for re-sanding. If you have interlock, sand re-application should be quoted upfront, not sprung on you as an add-on.
  5. Verify insurance. $2M liability. Pressure washers can damage windows, strip paint, erode mortar. Insurance protects you.
