Exterior House Washing Cost: What You’ll Pay in 2026
Most homeowners pay between $180 and $450 to have the outside of their house washed, with a national average around $300. The exterior house washing cost you end up with depends mostly on square footage, the number of stories, your siding material, and how dirty the surfaces actually are. A simple single-story ranch might cost $150, while a large two-story home with stubborn mildew can push past $800.
The good news is that washing your home’s exterior is one of the cheapest maintenance jobs you can do per square foot, and it delivers visible results the same day. This guide breaks down real numbers, compares pressure washing against soft washing, and shows you when it makes sense to pull out your own equipment instead of hiring a pro.
How Much Does Exterior House Washing Cost on Average?
The typical exterior house washing cost breaks down to roughly $0.10 to $0.50 per square foot, with most contractors landing in the $0.15 to $0.35 range. For a standard 1,500-2,000 square foot single-family home, that works out to:
- Single story (1,000-1,500 sq ft): $150 – $300
- Single story, full wash of a larger home (2,000-2,500 sq ft): $250 – $450
- Two-story home: $350 – $700, sometimes more with heavy staining
- Soft wash of the same home: typically 20-40% higher than basic pressure washing
Contractors rarely quote a flat “per house” number anymore. Most estimate by measuring the total washable area, which includes walls, soffits, trim, and sometimes gutters, porches, and walkways. When you see a very low quote, check what it actually covers: a $99 “house wash” special usually targets a single-story home under 1,400 square feet and skips the gutters and driveway.
Factors That Move Your Exterior House Washing Cost
Several variables shift the final price more than anything else. Knowing them helps you read a quote and spot whether you’re being charged fairly.
Siding material
What your house wears on its walls changes both price and technique:
- Vinyl siding: the cheapest to wash, roughly $0.10 – $0.25 per square foot. It tolerates low-pressure washing well.
- Wood siding and cedar shakes: $0.25 – $0.50 per square foot. Requires soft washing or gentle pressure so you do not splinter or gouge the grain.
- Brick and stone: $0.25 – $0.60 per square foot. Porous masonry holds onto grime and needs more dwell time and more chemical.
- Stucco: $0.20 – $0.45 per square foot. Too much pressure blasts the finish off, so pros almost always soft wash it.
- Fiber cement (HardiePlank): $0.20 – $0.40 per square foot. Washes well but needs a gentle touch to protect the paint film.
Height and access
A second story adds 40-60% to the job. Reaching upper walls safely means extension wands, ladders, scaffolding, or a lift, all of which slow the crew down and add labor. Homes with tight side yards, landscaping tight to the walls, or steep grades cost more because the crew has to work around obstacles.
How dirty the house is
Light dust and pollen rinse off fast. Green algae, black staining, or years of baked-on mildew require the contractor to pre-treat with a sodium hypochlorite or sodium percarbonate solution and let it dwell, which adds time and product. Expect to pay on the higher end if your north-facing walls are streaked with green or black growth.
Your region
Labor rates drive the number more than anything. A full house wash in a high-cost metro area can run 30-50% more than the same job in a rural market. As a rough rule, expect to pay more in the Northeast and West Coast and less across the South and Midwest.

Pressure Washing vs. Soft Washing: What You’re Really Paying For
These are two different jobs, and it is important not to confuse them when comparing exterior house washing costs.
| Feature | Pressure Washing | Soft Washing |
|---|---|---|
| Typical cost | $0.15 – $0.35 / sq ft | $0.25 – $0.50 / sq ft |
| Water pressure | 1,500 – 3,500 PSI | Under 500 PSI |
| Cleaning action | Blasts grime off with force | Chemical dwell time does the work |
| Best for | Concrete, brick walks, patios | Vinyl, wood, stucco, roofs |
| Risk to siding | Can etch, gouge, or loosen paint | Very low |
Pressure washing relies on high-pressure water to physically blast dirt loose. It is ideal for hard surfaces like concrete driveways, brick, and stone, but it can damage softer siding if the operator uses the wrong tip or too much force.
Soft washing uses a pump that pushes a cleaning solution — usually water, a low-strength bleach mix, and a surfactant — onto the surface at low pressure. The chemicals kill algae, mold, and mildew at the root, which is why soft washing results last longer on siding. For vinyl, stucco, wood, or painted surfaces, soft washing is the safer and often longer-lasting choice, even though it costs a bit more per square foot.
If a contractor quotes you for “house washing” without specifying the method, ask. The right answer depends on your siding, and a reputable pro will explain the difference rather than defaulting to maximum pressure on everything.
DIY vs. Hiring a Pro: The Real Math
Washing your own house is doable, but the savings are smaller than they look once you account for equipment, chemicals, and your own time.
Doing it yourself
- Renting a gas pressure washer: $40 – $100 per day from a big-box or equipment rental store
- Buying an entry-level electric pressure washer: $150 – $400 (a 1,500-2,000 PSI unit like a Ryobi or Greenworks model handles most siding)
- Soft-wash chemicals and a pump sprayer: $40 – $120
- Your time: a full day for the average two-story home, plus setup and cleanup
Hiring a pro
- Typical full wash: $250 – $450 for an average single-family home
- Soft wash with mold treatment: $350 – $600
- What you get: insurance, correct chemicals, gutter and trim coverage, and no risk of blowing siding loose or falling off a ladder

The break-even is roughly one to two days of your own labor, which is why many homeowners who ask about exterior house washing cost still hire out the job. The real risk is not just the money — a pressure washer in the wrong spot can force water behind siding, causing rot and mold, or strip paint you then have to repaint. Our guide to how to pressure wash a house walks through the technique if you decide to tackle it yourself.
Exterior House Washing Cost by Surface
If you are pricing out a broader project, here is what each surface typically adds. Most pros bundle these into a “house plus” quote rather than charging full price for each line item.
- House siding (walls and trim): $150 – $500, the core of the job
- Gutters and fascia: $75 – $150 when added to a full wash
- Driveway and walkways: $0.10 – $0.35 per square foot, usually $100 – $250 for a two-car driveway
- Deck or patio: $0.30 – $60 per square foot depending on material
- Roof (soft wash, no pressure): $0.20 – $0.60 per square foot
A useful rule of thumb: a “whole exterior” package covering the house, gutters, driveway, and walkways usually lands between $450 and $900 for an average home. That is still cheaper than letting grime and mildew sit until they cause staining you cannot reverse or rot you have to repair.
How to Save Money on Exterior House Washing
You can lower your exterior house washing cost without cutting corners on the work itself.
- Wash yearly instead of waiting for a deep clean. Lighter, more frequent washes cost less than rescuing a heavily stained surface, and they keep algae from taking hold.
- Bundle services. Adding the driveway, deck, or gutters to a house wash costs far less than booking them separately.
- Get at least three quotes. Prices swing more on this job than almost any other. Compare line-item quotes, not just bottom-line numbers.
- Wash in the spring or fall. Demand peaks in early summer; off-season scheduling can knock 10-20% off, especially in cooler climates where crews have gaps.
- Handle the prep yourself. Move patio furniture, trim back shrubs, and clear the work area so the crew is not billing you for moving your stuff.
- Check what maintenance repairs the wash exposes. Loose or cracked caulk lets water in every time it rains. Once the siding is clean and dry, sealing gaps is a cheap follow-up — see our exterior caulking guide for the steps.
Frequently Asked Questions
How often should I wash the outside of my house?
In most climates, once a year is enough to keep siding clean and prevent algae and mildew buildup. Homes in humid, shaded, or coastal areas may need a wash every six months on the worse-facing walls.
Can I pressure wash my own house to save money?
Yes, as long as you use the right pressure and technique for your siding. Vinyl and painted wood are easy to damage with a narrow spray tip, and soft washing is often the safer DIY route for those surfaces.
What is the difference between pressure washing and soft washing in price?
Soft washing typically runs 20-40% higher than basic pressure washing because it uses a chemical dwell process and takes a little more setup. It also lasts longer on siding because it kills mold and algae at the root rather than just blasting the visible layer off.
Should I wash my roof with a pressure washer?
No. High pressure can lift shingles and void your warranty. Roofs should be soft washed with a cleaning solution and low pressure, or left to a professional who specializes in roof cleaning.
Is exterior house washing worth the cost?
For most homeowners, yes. Regular washing protects paint and siding, prevents stains from becoming permanent, and lets you spot cracks, rot, and failing caulk while they are still cheap to fix. It is one of the lowest-cost-per-square-foot maintenance jobs on the home.
The Bottom Line
For most homes, exterior house washing cost lands between $180 and $450, or roughly $0.15 to $0.35 per square foot. The two biggest price drivers are your siding material and whether the home is one or two stories. Soft washing costs a little more than pressure washing but is the safer, longer-lasting choice for vinyl, wood, and stucco surfaces.
Get three line-item quotes, ask whether the contractor plans to pressure wash or soft wash, and consider bundling the driveway and gutters into the same visit. If you want to own the job yourself, a rented machine and an afternoon will do it — just match the pressure to the surface. Either way, a clean exterior protects your siding, extends your paint job, and makes the whole house look newer, and that is a return worth paying for.
