The short answer
In London, Ontario, most professional driveway washes start around $150-200. A full house wash is priced by square footage and siding type, so it varies more - but every reputable company should give you a free, exact quote before any work begins. At PowerShine, quotes are always free and transparent with no hidden fees.
Beware of prices that sound too good to be true. A rock-bottom quote usually means a quick rinse with no detergents - which is why the grime comes back within weeks. Professional cleaning uses biodegradable detergents to break down buildup at the source, so the surface actually stays clean.
What changes the price
Four things move a pressure washing quote up or down. First, surface area: a double-wide driveway costs more than a single walkway. Second, buildup: years of embedded winter salt, oil stains, and moss take more time and product than an annual maintenance clean. Third, the material: high-traffic concrete can take full cleaning power, while wood decks and delicate pavers need a slower, low-pressure soft-wash approach. Fourth, add-ons like concrete sealing, which guards against cracking and weeds after the clean.
London properties carry a specific burden: salt and sand from the winter roads get ground deep into concrete, and the humid summers feed algae and moss on any shaded surface. That is why local pricing reflects deep cleaning rather than a garden-hose rinse.
Driveway, patio, deck: how each is priced
Driveways are the most predictable job - flat concrete, priced mostly by size and staining, starting around $150-200. Patios and walkways are similar but often need moss and algae removal from between pavers, with care taken to preserve the sand joints. Wood decks are a different service entirely: they need low-PSI, wood-safe washing, and if the wood is grey and weathered, cleaning is usually the first step of a staining and restoration job rather than a standalone wash.
When pressure washing is the wrong buy
If the dirty surface is your siding, roof, or anything painted, do not order pressure washing at all - order soft washing. High pressure can crack vinyl, etch brick, and drive water into wall cavities, and on shingles it strips the protective granules and can void the manufacturer warranty. Soft washing costs are similar, but the method (low pressure plus eco-friendly cleaning solutions) is what those surfaces actually need.
