If you've typed "how much does it cost to pressure wash a house" into a search bar, you've probably already found ten answers that each say something different. That's because the honest answer is "it depends," and most articles bury the things it actually depends on. This one puts them up front.
Here's the short version: in 2026, most homeowners pay between $250 and $600 to have a house exterior washed, with a national average around $400. A small single-story house can come in at $180 to $300. A large two-story house with heavy buildup can run $500 to $900. The rest of this guide explains what moves you within that range, and what to watch for so you don't overpay or hire the wrong person.
Average house washing cost by home size
Home size is the biggest single factor, because most washing is priced on the surface area being cleaned. Here's what typical full-exterior house washing runs in 2026.
| Home size | Typical square footage | Average cost |
|---|---|---|
| Small single-story | Up to 1,500 sq ft | $180 to $300 |
| Average single-story | 1,500 to 2,500 sq ft | $250 to $450 |
| Two-story | 2,000 to 3,000 sq ft | $400 to $650 |
| Large two-story | 3,000+ sq ft | $500 to $900 |
These are full-exterior washes (the siding, not the driveway or roof). If you bundle in a driveway, walkways, a deck, or roof cleaning, expect each of those to add to the total. More on that below.
Cost per square foot
Many pressure washing companies price house washing per square foot of surface area, usually in the range of $0.15 to $0.45 per square foot, then adjust up or down based on the specifics. Some quote a flat price per house instead, which is really the same math done in their head. Either way, when you call for a quote, expect to be asked your home's approximate square footage and number of stories.
If you want to understand the contractor's side of that number, the per-surface rates are broken down in our 2026 pressure washing rates guide. It's written for the people doing the work, but it's the clearest way to see what you're actually paying for.
What changes the price
Two houses of the same size can get quotes hundreds of dollars apart. Here's why.
Number of stories
A two-story house costs more than a one-story house of the same square footage, because the upper level needs extension equipment or ladders, takes longer, and carries more risk for the operator. Height is one of the biggest price multipliers after raw size.
Siding material
Vinyl siding is the easiest and cheapest to clean. Brick, stucco, and painted wood take more care, more time, or gentler methods, which raises the price. Delicate or older surfaces sometimes require hand-detailing that a straightforward vinyl wash doesn't.
How dirty it is
A light refresh costs less than removing years of green algae, black streaking, or mildew. Heavy organic growth needs more cleaning solution and more dwell time, and that shows up in the price. If you wash every year, each wash is cheaper than letting it go for five years and paying for a heavy restoration.
Your location
Prices run higher in high-cost metros and coastal areas, and lower in rural and inland markets, the same way most local services do. A house wash in San Francisco or Boston costs more than the identical job in rural Tennessee.
Add-ons
The house exterior is one line. Driveways, sidewalks, patios, decks, fences, and roof cleaning are usually quoted separately. Bundling several at once often gets you a better per-service rate than booking them one at a time, so if you want the whole property done, ask for a package price.
Pressure washing vs soft washing your house
This is the one thing worth understanding before you hire anyone, because it protects your home.
High-pressure water is right for hard surfaces: concrete driveways, brick, pavers. It is the wrong tool for most house exteriors. Blasting high pressure at vinyl siding can force water behind it; on stucco it can chip the surface; on a roof it can strip shingle granules and void your roof warranty. The correct method for siding and roofs is soft washing, which uses low pressure plus a cleaning solution that does the work chemically.
Most reputable companies soft wash house exteriors even when they advertise the service as "pressure washing," because that's the search term everyone uses. When you get a quote, it's worth one question: "Do you soft wash siding, or use high pressure?" The right answer for siding is soft wash. If a company wants to put 3,000 PSI on your vinyl, keep calling.
An operator who underbids may be uninsured, may rush, or may use high pressure where soft washing is called for. Damage to siding, windows, or a roof costs far more than the few dollars you saved. Always confirm the company carries liability insurance before they start.
How to avoid overpaying
You don't need to become an expert to get a fair price. A few habits do most of the work.
- Get two or three quotes. Prices vary more than people expect for the same job. Three quotes tells you the real local range in an afternoon.
- Get it in writing. A written, itemized quote that lists each surface and price protects you from surprise charges and tells you the company is run professionally. A number texted with no detail is a yellow flag.
- Confirm insurance. Ask for proof of general liability insurance. A real company will have it ready; an uninsured one will get evasive.
- Ask what's included. Does the price cover pre-treatment, the full rinse, and cleanup? Are stains beyond normal washing extra? Knowing the scope up front prevents the "that wasn't included" conversation later.
- Bundle if you can. If you want the driveway and deck done too, ask for a package price rather than booking each separately.

Once a year is a sensible baseline for most homes. If you're in a humid climate, under heavy tree cover, or near the coast, every six to nine months keeps mold, algae, and salt from taking hold. In drier inland climates you can often stretch to every 18 to 24 months. The longer you wait, the more buildup there is to remove, and the more each wash costs, so an annual rhythm is usually cheaper over time than occasional heavy restorations.
Is it worth it?
For curb appeal, yes, and especially before selling. A clean exterior photographs better, shows better, and removes any impression of neglect. Washing doesn't raise your appraised value by itself, but as a few-hundred-dollar move before listing a house, it's one of the cheapest improvements with a visible payoff, and real estate guidance consistently ranks curb appeal among the highest-return pre-sale moves. For ongoing maintenance, regular washing also prevents algae and mildew from degrading siding and shingles over time, which protects the bigger investment underneath.
And if you're reading this from the other side, because you're thinking about offering this service rather than buying it, the money in house washing is real. Our guide on how to start a pressure washing business walks through the startup costs, gear, and pricing.
The bottom line
Budget $250 to $600 for a typical house wash in 2026, knowing that home size, height, siding, dirt level, and your region move you within that range. Get a few written quotes, confirm the company is insured, and make sure they soft wash your siding rather than blasting it. Do that and you'll pay a fair price for a job done right, which is the whole goal.
