Pressure Washing in Dovercourt-Wallace Emerson-Junction

Light rain is usually fine — surfaces are already wet. Pros avoid freezing temperatures (ice risk on cleaned surfaces and damaged equipment) and heavy storms. In hot dry regions, local water restrictions can limit or ban high-volume outdoor cleaning during drought periods, so check the current rules before booking.

Once a year is the common rhythm for driveways and house exteriors in temperate climates. Humid or coastal areas may need it every 6-12 months because algae, mould, and salt build up faster. Waiting longer than 2-3 years lets organic growth bind to the surface, which raises the price of the eventual clean.

Most pros charge either by the hour or by surface area. A single driveway or patio is typically a 1-3 hour job at the low end of a pro's minimum call-out, while a full house exterior wash costs several times more. Get the quote broken down by surface (driveway, walls, deck, roof) so you can drop items to fit your budget.

Fresh oil mostly comes out with a degreaser pre-treatment plus hot-water pressure washing. Old oil that has soaked deep into concrete may only fade, not disappear — an honest pro will tell you this before quoting rather than promising full removal. Ask specifically whether stain treatment is included or extra.

A proper quote lists: each surface and its approximate area, the method per surface (high pressure vs soft wash), pre-treatments or chemicals used, weed and moss removal, rinsing and tidy-up, and whether resealing or re-sanding is included. It should also state who supplies water and power, and what happens if rain forces a reschedule.

Roughly April to October in most provinces — pros stop when temperatures approach freezing because wet surfaces become ice hazards and equipment can freeze. That short season means spring slots book out weeks ahead; fall is often easier to schedule.

A typical single-storey house wash runs roughly $250-$500, and driveways $130-$400 depending on size and staining. Expect quotes 10-20% above US prices in dollar terms, with Toronto and Vancouver at the top of the range.
