Nobody likes getting a quote that feels pulled out of thin air, so here are the real numbers: what a house wash actually costs in Asheville, what pushes the price up or down, and where hourly rates come into play. You’ll walk away knowing what a fair quote looks like before anyone shows up at your door.
The Baseline Numbers
Most house washing in the Asheville area runs $0.35 to $0.77 per square foot of exterior surface. For a typical 1,500-2,000 square foot home, that works out to a total job cost of about $212 to $450, with most jobs landing around $310. That range isn’t random — it reflects how much time and product a job takes, which depends on the siding material, how dirty it is, and how accessible the house is.
Some smaller add-on jobs get billed hourly instead of by square footage, typically $50-100 an hour. That’s more common for things like a quick gutter brightening pass or a small patio that doesn’t justify a full square-footage estimate.
What Pushes Your Price Toward the Higher End
- Wood or stucco siding — adds roughly $50-150 to the job, since both require gentler technique, more careful chemical dilution, and more time than vinyl.
- Heavy tree cover — homes shaded by Blue Ridge hardwoods develop thicker algae and mold buildup, especially on north-facing walls, which takes longer to treat properly.
- Multiple stories or steep rooflines — more setup time, more safety equipment, more careful work around windows and trim.
- Long dwell requirements — a heavily soiled surface may need a second application of cleaning solution and another 10-15 minute dwell before rinsing, which adds labor time.
- Bundled services — combining a house wash with a driveway, deck, or roof soft wash usually gets you a better per-job rate than booking each separately.
What Should Be Included in Your Quote
A fair quote should be given to you before the job starts, not adjusted afterward once the crew is already there. It should specify the technique per surface (soft wash for siding and roof, pressure wash for concrete), roughly how much square footage is being covered, and whether the price includes pre-treating stains, gutter brightening, or window rinsing as part of the job.
Be cautious of a quote that’s dramatically below the $0.35/sqft floor — that’s often a sign the company is skipping dwell time or using plain water with no cleaning solution, which means the algae and mold will be back within a couple months instead of staying clean for the season.
Frequently Asked Questions
Why does wood or stucco siding cost more to wash?
Both materials are more porous and more easily damaged than vinyl, so they require a gentler soft-wash technique, more careful chemical dilution, and slower, more deliberate work. That extra care and time is reflected in the $50-150 upcharge.
Is a driveway or deck wash priced the same as a house wash?
Not usually — those are often priced separately, either by square footage or hourly ($50-100/hr for smaller jobs), and get bundled with a house wash for a combined discount if you’re doing both at once.
Should I be suspicious of a quote that’s way cheaper than $212 for a 1,500 sqft home?
Yes, worth asking questions. A price well under the typical range often means the contractor is skipping the cleaning solution and dwell time and just rinsing with plain water, which looks fine the day of but doesn’t actually kill algae and mold at the root.
