A pressure washing business cleans homes, driveways, sidewalks, decks, fences, roofs, storefronts, parking lots, dumpster pads and fleets. Many companies combine pressure washing (high-pressure water for hard surfaces) with soft washing (low pressure plus cleaning solutions for siding and roofs).
Startup costs are moderate, and demand is strong from homeowners, HOAs and businesses. But exterior cleaning has environmental rules: wash water carrying chemicals, oil and debris generally must not flow into storm drains, which can violate Clean Water Act-based local stormwater rules. Cleaning chemicals require safety training, and products labeled to kill mold or algae are regulated pesticides. Advanton’s data shows a median pay of $35,930 for janitors and cleaners, the closest occupation. This guide covers equipment, techniques, rules, pricing, a worked example and a 90-day plan.

Who pressure washing suits
It suits hands-on people who enjoy physical outdoor work, take care with property and chemicals and like visible results. Learning which pressure and solution fits each surface prevents costly damage.
Equipment
- Pressure washer with enough flow (gallons per minute) and pressure for professional work.
- Surface cleaner for driveways and flatwork.
- Soft wash system with a pump for applying cleaning solutions at low pressure.
- Hoses, reels, nozzles and extension wands.
- Water tank for jobs without reliable water supply.
- Wastewater recovery equipment for commercial jobs where required.
Pressure vs soft washing
High pressure works for concrete and hard surfaces, but can damage siding, roofs, wood and windows. Soft washing uses low pressure and cleaning solutions to remove mold, mildew and algae from siding and roofs. Roofing and siding manufacturers often recommend low-pressure cleaning, so learn their guidance.
Wastewater and storm drains
Wash water can carry detergents, oil, grease, paint flakes and debris. Under Clean Water Act-based stormwater programs, many cities prohibit discharging it into storm drains, which flow to streams and lakes. Use drain covers or berms, direct water to landscaped areas where allowed, recover and dispose of wastewater properly for commercial and greasy jobs and follow local rules.
Chemicals and pesticide rules
Common solutions include sodium hypochlorite (bleach) for mold and algae, surfactants and degreasers. Follow safety data sheets, train workers under OSHA’s Hazard Communication standard and wear eye and skin protection. Products whose labels claim to kill mold, mildew or algae are EPA-registered antimicrobial pesticides, and the label is the law: follow its directions, and check whether your state requires a commercial pesticide applicator license for these treatments.
Protecting property and plants
Pre-wet and rinse plants, cover sensitive fixtures, close windows, test solutions on small areas and avoid forcing water behind siding or into electrical outlets. Damage claims can wipe out profits, so careful work matters.
Insurance
Carry general liability insurance (property damage is common in exterior work), workers’ compensation for employees, which is often required by law, and commercial auto coverage. Many commercial clients require certificates of insurance before you start.

Pricing
Price flatwork by square foot, house washes by size and stories and roofs by area and difficulty, with minimum job charges. Commercial clients often sign recurring contracts for storefronts, dumpster pads and drive-throughs. Use our pricing calculator.
A worked example: a one-rig operation
These are illustrative assumptions for a one-rig operation in peak season, not predictions.
| Assumption | Monthly | |
|---|---|---|
| House washes | 30 houses averaging $375 | $11,250 |
| Driveways, decks and fences | $5,500 | |
| Commercial flatwork and storefronts | $3,500 | |
| Revenue | $20,250 | |
| Chemicals and supplies | $(1,300) | |
| Helper wages | With payroll costs | $(3,800) |
| Fuel, water and equipment maintenance | $(1,200) | |
| Truck and rig payments | $(900) | |
| Insurance, software and marketing | $(1,500) | |
| Profit before owner pay and taxes | $11,550 |
That leaves about $11,550 in a peak month before the owner’s pay and taxes, on about $20,250 of revenue. Commercial maintenance contracts keep work coming in slower months.

Finding customers
- Homeowners through before-and-after photos and local search.
- HOAs and property managers for sidewalks and buildings.
- Restaurants and retailers for storefronts and dumpster pads.
- Realtors preparing listings.
- Fleet owners for vehicle washing, where wastewater rules allow.
Roof cleaning
Roof cleaning removes algae streaks, moss and lichen using soft washing at low pressure, never high pressure that can damage shingles. Follow roofing manufacturer guidance and chemical labels, protect plants and gutters and use fall protection on roofs. Roof cleaning commands premium prices.
Commercial contracts
Restaurants, gas stations, shopping centers, apartment complexes and HOAs need regular cleaning of sidewalks, drive-throughs, dumpster pads and building exteriors. Commercial work often happens at night or early morning and requires stronger wastewater controls for grease and oil.
Fleet washing
Washing trucks and vans for businesses can bring steady recurring work, but fleet washing produces wastewater with oil and grime that many cities require you to capture and dispose of properly. Check local rules before offering it.
Deck and fence restoration
Wood decks and fences need gentle cleaning, brightening and often sealing or staining. Restoration packages raise job value, but require knowledge of wood types and coatings to avoid damage.
Water supply
Professional machines use a lot of water. Confirm water access and flow at each site, carry a buffer tank and follow local water use restrictions during droughts.
Estimating jobs
Measure square footage for flatwork, note surface types and stains, check water access and drainage and photograph the site. Accurate estimates prevent undercharging for oil stains, rust and heavy algae, which take more time and chemicals.
Building recurring work
Offer annual house wash plans, quarterly storefront cleaning and monthly dumpster pad service. Recurring work smooths seasonality and makes the business more valuable.
Choosing a niche
Some companies specialize in residential house washing and roofs, others in commercial flatwork, restaurants, fleets or HOAs. A niche shapes equipment, pricing, marketing and the environmental controls you need.
Customer education
Explain why soft washing protects siding and roofs, how long results last and how regular cleaning prevents damage from algae and grime. Educated customers value professional service over cheap, damaging work.
