Most pressure washing jobs in Ottawa cost between $180 and $650 in 2026, working out to roughly $0.20 to $0.55 per square foot of surface. A typical two-car concrete driveway runs about $180–$320, a single-storey house wash lands around $300–$500, a two-storey soft wash is closer to $450–$750, and a 300 sq ft deck or patio is usually $150–$280. Hourly rates from local operators generally sit between $80 and $150, though most quote by the job. Ottawa's season is short — reliable exterior washing runs from roughly mid-April through late October, and the spring rush after winter road salt and san...
Contractors price by surface because each one needs different pressure, chemicals, and time. Concrete driveways are the most common request in Ottawa, and a standard two-car drive of roughly 600–700 sq ft runs $180–$320; add $60–$120 if you want a post-wash sealer applied. Interlock and paver driveways cost more — about $0.40–$0.70 per sq ft — because sand joints need re-sweeping afterward, often adding $100–$250 in polymeric sand. Vinyl or aluminum siding is almost always soft washed rather tha...
Many local operators offer packages: driveway plus walkway plus front steps around $280–$420, or a full exterior package with house soft wash, driveway, walkway, and deck between $700 and $1,200 for a typical suburban home in Kanata, Barrhaven, or Orléans.
These are two different services and confusing them is how homeowners end up with damage. Pressure washing uses high water pressure, typically 2,000–4,000 PSI, and is appropriate for concrete, brick, and stone. Soft washing uses low pressure — often under 500 PSI — combined with a detergent and sodium hypochlorite solution that kills algae, mildew, and the green-black film that builds up on Ottawa's north-facing walls. Siding, stucco, roofs, and painted surfaces should always be soft washed. Hig...
Timing shapes both availability and price locally. The washing season effectively runs from mid-April, once overnight temperatures stay above freezing, to late October, and the heaviest demand hits in May when homeowners want winter salt, sand, and grit off their driveways and lower siding. Booking in June or September often gets you better scheduling and occasionally better rates. Cost drivers beyond square footage include heavy staining — oil spots, rust, or years of algae — which can add $50–...
Ottawa's sewer use by-law restricts discharging chemical-laden wastewater into storm drains. Professional operators direct runoff onto lawns or landscaped areas where soil can filter it, or use containment mats on commercial jobs. Ask how they manage runoff — it signals whether they know the local r...
Renting a pressure washer in Ottawa costs about $60–$100 for a half day or $90–$150 for a full day, plus fuel, and you'll need a vehicle that can transport it. For a single driveway, DIY can genuinely save $100 or more. Where it stops making sense is anything above ground level, any siding or roof work, and any surface where a mistake is expensive. Consumer and rental units are easy to misuse: too much pressure etches concrete permanently, leaves visible wand-stripe marks, strips deck fibres, an...
Give contractors your approximate square footage and photos of the worst areas so they can quote realistically instead of padding for the unknown. A solid written quote states which surfaces are included, whether it's soft washing or pressure washing on each, what detergents are used, whether sealing or polymeric sand re-application is extra, and how long the job will take. Confirm general liability insurance — water damage claims from a bad siding wash are real — and WSIB coverage if a crew is ...
Most Ottawa pressure washing jobs run $180–$650 in 2026, roughly $0.20–$0.55 per square foot. A two-car driveway is about $180–$320, a single-storey house wash $300–$500, and a two-storey soft wash $450–$750.
A standard two-car concrete driveway of 600–700 sq ft costs about $180–$320. Interlock or paver driveways cost more, around $0.40–$0.70 per sq ft, because the sand joints need re-sweeping afterward.
Siding should always be soft washed at low pressure with a cleaning solution. High-pressure washing forces water behind vinyl panels and into the wall assembly, which can cause moisture damage and void siding warranties.
The season runs from about mid-April to late October. May is peak demand as homeowners clear winter salt and sand, so booking in June or September usually gets you faster scheduling and sometimes better pricing.
Renting costs about $60–$150 per day, so DIY can save money on a single driveway. It's not recommended for siding, roofs, or anything above ground level, where misuse can etch surfaces or drive water into the wall.
