For most single-family homes, a professional exterior wash runs roughly $250 to $700. Larger, taller, or heavily stained houses can climb past $1,000. That’s the starting answer to how much does it cost to have a house washed. Where you land in that range depends on a handful of factors you can predict, and a few you can influence.
This guide covers typical house washing prices by home size, what moves a quote up or down, and how soft washing and pressure washing compare on cost. It also explains how to read an estimate before you say yes, and how often a house in Northern Kentucky tends to need attention.
Typical House Washing Prices
The average house washing cost is easiest to understand two ways: as a flat price for the whole job, and as a rate per square foot. Professionals usually figure house washing cost per square foot from the cleanable wall area, not the floor area. Typical rates run from about $0.15 to $0.60 per square foot, with gentler, more careful methods toward the upper end. The table turns that into estimated totals for common homes.
| Home type | Estimated range | What pushes it higher |
|---|---|---|
| Small single-story (about 1,200–1,500 sq ft) | $200–$450 | Heavy growth, tight landscaping |
| Average two-story (about 2,000–2,500 sq ft) | $350–$700 | Height, multiple gables, shaded walls |
| Large or multi-story (3,000+ sq ft) | $600–$1,200+ | Tall walls, complex rooflines, difficult access |
| Heavy buildup or delicate siding (cedar, stucco, aged paint) | $1,000+ | Extra treatment passes, slower methods |
| Roof soft wash (add-on) | $350–$1,000+ | Pitch, size, black algae streaking |
These are general estimates, not confirmed prices. The final cost depends on home size and number of stories, siding type, level of buildup, accessibility, labor and equipment time, add-on surfaces, and other factors. A written, itemized quote after the home is measured and inspected is the only reliable number.
Wall area drives the work, which is why a two-story house costs more to wash than a ranch with the same square footage. More wall means more surface to treat, and upper stories take more time and setup.
What Shapes Your House Washing Estimate
Behind every quote are labor, equipment, and cleaning solutions, and labor is usually the biggest piece. These are the details that move it.
Size and stories. Square footage sets the baseline, but height matters just as much. Reaching a second story safely takes extension poles, ladders, or lifts, and that takes time.
Siding type. Vinyl is the most forgiving and usually the least expensive to wash. Brick is durable but traps grime in its mortar joints. Stucco and painted wood are more porous and delicate, so they call for gentler methods and slower work, which raises the house washing service price.
Dirt buildup and growth. Light dust and pollen rinse off quickly. Green streaks and black spotting are usually mold and algae growth rather than ordinary dirt. They need cleaning solution time to break down at the root, and stubborn patches may need a second application, which can add roughly $100 to $300.
Access and extras. Dense shrubs, steep grades, and the lack of an outdoor water source all add time, as does protecting nearby plants. Bundling jobs, such as a house wash with a driveway or deck, often lowers the per-job overhead, so ask for combined pricing.
Soft Washing vs. Pressure Washing: Does the Method Change the Price?
Pressure washing uses high pressure to blast loose grime off hard, durable surfaces like concrete. Soft washing uses low pressure plus a cleaning solution that sits on the surface, then gets rinsed away. That lifts algae, mold, and mildew instead of blasting them off. For siding, many pros favor soft washing.
That’s why the soft washing house cost often runs a little higher per square foot than basic high-pressure cleaning. You’re paying for the solution mix and careful application, but you’re reducing the risk of damage. Vinyl Siding Institute guidance notes that some manufacturers don’t want pressure washers used on their siding at all, and others limit pressure and cleaners. It also advises spraying straight at the wall, not at an angle, to avoid driving water behind the siding.
A low bid built on high pressure can cost you more in repairs than it saved. When comparing pressure washing house cost quotes, ask which method will be used on your siding, not just what the total is. Contractors that offer a dedicated house washing service alongside general pressure washing usually match the method to the surface.
Is DIY Cheaper?
Renting a pressure washer runs about $75 a day, so the upfront math looks appealing for a small single-story home with vinyl siding. The savings shrink once you count cleaner, safety gear, and a Saturday of work. The risks are also real:
- Water forced behind siding or around window seals
- Streaking from uneven passes
- Stains from the wrong chemicals
- Runoff that harms landscaping
- Ladder work on upper floors
For two-story homes, delicate siding, or heavy growth, hiring a pro is usually the safer call, because mistakes there tend to cost more than the service.
How Often to Wash and How to Keep Costs Down
Boone County sits in a humid subtropical climate with roughly 40 inches of precipitation a year and warm, humid summers. Those are conditions algae and mildew like, especially on shaded or north-facing walls and homes under mature trees. A house in full sun may go longer between washes than one tucked beneath maples, so how often you should pressure wash your home depends on shade, moisture, and siding more than on any fixed calendar.
Regular washing keeps buildup light, and light buildup keeps each visit closer to the low end of the price range than waiting until growth is thick. A few other habits help:
- Trim shrubs back from the walls before the crew arrives.
- Make sure an outdoor spigot and gates are accessible.
- Schedule during warmer months, when temperatures stay above freezing.
- Ask for a combined price if you also want a roof, deck, or driveway cleaned.
The national figures above are a starting point. The actual house washing cost in Burlington, KY comes from a measured, written quote for your specific home.
What to Look for in a House Washing Quote
A good house washing estimate makes the job easy to understand and compare. Before you approve one, check that it:
- Is written and itemized, showing what’s included and what isn’t
- Names the cleaning method and approach for your siding type
- Covers how landscaping and windows will be protected and rinsed
- Comes from a company willing to show proof of liability insurance

Quick Answers
How long does a house wash take?
A small single-story home may take a few hours. Large, multi-story, or multi-surface jobs can run a day or two.
Do I need to prepare anything?
Typically you’ll close windows, move furniture and decor away from the walls, and make sure the crew can reach an outdoor water source. Ask your contractor for their specific list.
Does the price include the roof, windows, or driveway?
Usually not. These are often priced separately, so confirm exactly what’s covered on the written quote.
