Pressure Washing Business Equipment and Pricing: What to Buy and What to Charge

Pressure washing is one of the fastest home service businesses to start. A capable machine, a few attachments and a truck or trailer can have you earning within weeks. The two things that decide whether it becomes a real business are the equipment you choose and the way you price. This guide covers both.

Pressure washing versus soft washing

Professionals use two methods, and knowing the difference prevents expensive damage.

• Pressure washing uses high pressure to clean hard surfaces such as concrete driveways, sidewalks and pavers.
• Soft washing uses low pressure with cleaning solutions to clean delicate surfaces such as vinyl siding, stucco, painted wood and roofs. The chemistry does the work, not the pressure.

Using high pressure on siding or shingles can strip paint, force water behind siding and void roof warranties. A professional business offers both methods.

The equipment list

Core cleaning equipment

Flow (GPM) matters more than pressure (PSI) for cleaning speed. A 4 GPM machine cleans much faster than a 2.5 GPM machine at the same pressure.

Water supply and transport

• Water tank (200 to 525 gallons) so you are not limited by a customer's tap flow: $300 to $1,500.
• Trailer or truck skid to carry everything: $2,000 to $10,000 for a trailer, more for a custom build.
• Buffer or float valve setup to feed the machine from the tank.

Safety and compliance gear

• Safety glasses, gloves, non-slip boots, chemical-resistant clothing.
• Ladder and ladder stabiliser for upper-storey work.
• Storm drain covers, berms and a water recovery system or vacuum, depending on local rules.
• Spill kit and safety data sheets for every chemical.

Startup budgets

Add business formation, general liability insurance (often $500 to $2,000 a year for a small operator), a website and initial marketing.

How to price pressure washing jobs

Driveways and flatwork

Price by square foot. Many companies charge roughly $0.15 to $0.40 per square foot, higher for heavy staining, oil spots or paver sealing. Set a minimum job price (often $150 to $250) so small jobs still pay for the trip.

Example: a 20 × 40 foot driveway (800 sq ft) at $0.25 = $200. Add $50 for an oil-stain treatment. Total $250.

House washing (soft wash)

Price by square foot of the home or by storeys and footprint. Common approaches charge a base price for a typical single-storey home and more for two-storey homes, plus extra for heavy mildew or difficult access.

Roof cleaning

Roof soft washing is priced higher because of risk, chemistry and time, usually per square foot of roof or per square. Only offer it once you have training, insurance and fall protection.

Commercial work

Storefronts, drive-throughs, dumpster pads, parking garages and fleet vehicles can become recurring contracts. Price per visit or per month with a set schedule. Commercial clients expect insurance certificates and reliable night or early-morning service.

Tip: Bundle services. "House wash + driveway + walkway" priced as a package raises your average ticket and keeps the customer from shopping each item.

Your hourly target

Whatever method you use, check the result against an hourly target. If you want to earn $100 to $150 per hour of on-site time after chemicals and fuel, a job that will take three hours should not be priced at $150. Time every job for the first month and adjust your rates.

Water and chemical rules

The Clean Water Act prohibits discharging pollutants into waters of the United States, and storm drains usually lead straight to creeks and rivers without treatment. Many cities have stormwater ordinances that apply to mobile washers. In practice:

• Block or protect storm drains near the job.
• Recover wash water where required and dispose of it to a sanitary sewer only with permission, or as your local utility directs.
• Use the least chemical necessary and follow the label.
• Ask your city's stormwater department what applies to mobile surface cleaning.

Getting customers

• Before-and-after photos are your strongest marketing; post them on your Google Business Profile and social media.
• Door hangers on the street where you just cleaned a driveway work well because neighbours can see the result.
• Seasonal offers in spring and before holidays.
• Commercial outreach to property managers, restaurants and HOAs for recurring work.

Mistakes to avoid

1. Buying a cheap consumer machine. Low GPM makes every job slower.
2. Using high pressure on soft surfaces. Damage claims can exceed a season's profit.
3. No minimum charge. Small jobs lose money without one.
4. Ignoring wastewater rules. Fines and complaints can follow.

A sample pricing sheet

Use this as a starting structure and replace the numbers with your market's rates.

Present prices as packages on your quote: "Front of home refresh" (driveway, walkway, entry) and "Whole home" (house wash, all flatwork, fence). Packages raise the average job value and are easier for homeowners to say yes to.

Insurance and liability

Even a small pressure washing business needs general liability insurance. The risks are real: etched glass, stripped paint, water intrusion, chemical damage to plants and cars, and slips. Many commercial clients require a certificate of insurance before you start. If you add roof cleaning or hire helpers, review your coverage, add workers' compensation where required, and confirm the policy does not exclude the services you offer.

Questions readers ask

Is hot water necessary?

Not for most residential work. Hot water units excel at grease, oil and gum removal on commercial jobs such as drive-throughs and parking garages, but they cost much more. Start with cold water and add a hot water unit when commercial demand justifies it.

Do I need a licence for pressure washing?

Most areas require only a general business licence, but some cities regulate wastewater discharge for mobile washers, and roof or chemical work may have additional rules. Check with your city and stormwater authority before you start.

Your next step

Decide whether you will start with a starter cart or a trailer rig, price your local market by calling three competitors for quotes, and set your minimum job price.
