What it costs
Three shapes of job, and what each one runs.
Exterior cleaning is priced by surface and by what is growing on it. Ranges are what this work typically costs in this region in 2026, so you can see the scale before anyone comes out.
Single surface
One thing, done properly
A driveway, a patio or a deck that has gone dull.
$150 - $400per surface
- Surface cleaner rather than a hand-held wand, so the finish is even
- Pre-treatment on organic growth so it releases instead of being blasted off
- Plants covered and rinsed before and after
- Pressure matched to the material, not the same setting for everything

House wash most common
The whole exterior, soft washed
Siding with green or black growth on the shaded walls.
$300 - $700per house
- Soft wash at garden-hose pressure, which is what siding is rated for
- Gutter faces treated for the dark stripes, which plain washing leaves behind
- Windows and frames rinsed down afterwards
- Growth killed at the root so it stays off longer than a rinse

Whole property
House, roof and the flat surfaces
A property being sold, or one that has not been cleaned in years.
$700 - $1,800per property
- Roof soft washed for algae, never pressure washed
- House, driveway, walkways and patio in one visit
- Sealing offered on concrete or wood as a separate decision, not assumed
- Before and after photographs of each elevation

What moves the number
- How much organic growth there is, which is a chemistry and dwell-time cost rather than a time-on-site one
- The material: wood and painted surfaces need lower pressure and more care than concrete
- Access and height, particularly second-storey elevations and steep roofs
- Whether the surface has been damaged by a previous high-pressure clean
These are typical regional ranges for 2026, not a quote. Every job is
different and the only number that matters is the one you get in writing after somebody has
seen it. This is here so you know the scale before you pick up the phone.
