Nobody likes "it depends" as an answer to a pricing question. So here are real ranges for exterior cleaning in Durham Region, plus a plain explanation of what actually moves the price — so you can ballpark your own home before you call.
House soft wash — typical ranges
- Small home — roughly $200–300
- Medium home — roughly $300–500
- Large home — roughly $500–800+
These cover a full exterior soft wash of the siding — killing and removing the algae, mold, and mildew rather than just rinsing the surface. Driveways, decks, fences, and roofs are quoted separately, and bundling them into one visit is usually cheaper than booking each on its own.
The five things that move the number
Two houses that look the same size from the street can quote differently. Here's why:
- Size and height — more square footage and second- or third-storey walls take more time and reach
- How bad the growth is — a lightly dusty house cleans faster than one with years of heavy algae
- Surface type — vinyl, brick, stucco, and stone each need a slightly different approach
- Access — tight side yards, steep grades, and heavy landscaping slow the job down
- Add-ons — windows, soffits, gutters, or a walkway bundled into the same visit
Beware the quote that's far below everyone else. On siding and roofs, a suspiciously cheap price often means a pressure wand and a rushed job — the kind that damages the surface and grows back in months.
Why cheapest isn't the goal
Soft washing costs a bit more than a quick pressure blast because it uses the right solution and takes the time to kill the growth at the root. You're paying for a result that lasts years and a method that won't void your shingle warranty or drive water behind your siding. Done properly once beats done cheaply three times.
