How to Start a Pressure Washing Business

Few businesses have a better demo than pressure washing — half a dirty driveway on camera sells itself. Here is the equipment, the pricing, and the upsells that turn a $200 driveway into a $600 visit.

Licenses, Insurance, and Water Rules

A business license and general liability are the baseline; some cities add requirements around wastewater runoff and water reclamation, especially for commercial jobs. If you use cleaning chemicals, check whether your state regulates their application or disposal. The U.S. Small Business Administration can help you find local rules. Rules vary by state and city — check your local requirements before you start.

Liability matters here: high-pressure water damages siding, etches concrete, and strips paint when misused. Insurance plus proper technique — the right nozzle, the right distance — is the business.

Read your local stormwater rules carefully — letting chemical runoff reach storm drains can mean serious fines in many cities. Wash-water recovery mats and berms cost a few hundred dollars and turn compliance into a selling point on commercial bids.

Equipment: Washer, Surface Cleaner, Water

A commercial-grade pressure washer and a surface cleaner attachment are the core kit. Add hoses, wands, nozzles, chemicals, and a way to haul water if the job site lacks a spigot.

• Pressure washer (4+ GPM for pro speed), $300–$800
• Surface cleaner attachment, $100–$300
• Hoses, wands, and nozzle set
• Chemicals and downstream injector
• Water tank and trailer (for sites without water access)

Total startup runs roughly $1,000–$3,000. The surface cleaner is the highest-ROI purchase — it cuts driveway time in half and leaves the uniform finish that gets you referrals.

Learn soft washing (low pressure plus detergents) for siding and roofs — it cleans without damage and commands higher prices than blasting. The technique difference is what separates pros from the operator who etched a client's driveway with a zero-degree nozzle.

Do not overlook the vehicle setup: a dedicated trailer with the washer, tanks, hoses, and reels mounted and organized turns every job start into a five-minute setup instead of a thirty-minute unload. Time spent wrestling equipment in a client's driveway is unpaid and looks amateur — build the rig once, neatly, and every job after that starts professional. A lettered trailer doubles as a billboard parked at every job site, advertising to the whole street for free.

Pricing: Per Square Foot Plus Upsells

Driveways commonly price at $0.15–$0.30 per square foot; house washes run $250–$500+ depending on stories and siding. Quote flat per job after a look (or good photos) — never blind. Full breakdown: how much to charge for pressure washing.

The upsell ladder is where the money is: driveway, then driveway plus walkways, then the house wash, then the fence and deck. Each add-on takes minutes once you are set up — offer the bundle on the quote, not after.

Seasonal demand peaks in spring — price accordingly and book commercial contracts in winter when you have leverage. A spring-rush surcharge is normal in the industry; clients paying for speed understand it.

Finding Clients: Let the Work Advertise

Film every job: a 15-second before-and-after clip posted in local groups outperforms any ad. Hang door hangers in neighborhoods with visibly dirty driveways; HOA communities are efficient — one happy customer, twenty lookalike driveways.

Commercial work (storefronts, restaurants, fleets) pays more and repeats monthly — pitch property managers a maintenance plan, not a one-off. Recurring commercial routes are the closest thing this trade has to a salary.

Ask commercial clients for permission to put a small sign on-site during the job — a restaurant getting its patio washed in front of lunch customers is free advertising to exactly the right audience. Always ask first; never assume.

Neighborhood apps and local groups reward consistency: post your before-and-after clips weekly and the inquiries become routine.

Invoicing and Estimates

Use the free estimate maker for the quote — with the bundle options listed as line items — then convert it to an invoice in Billia when the job is done. Same-day invoicing, 7-day terms.

For commercial maintenance plans, invoice monthly with each visit as a line item. Recurring revenue is the goal; one-time driveways are the funnel that feeds it.

Have commercial clients sign off on completed work before you pack up — a two-minute walkthrough with the manager prevents the ‘you missed a spot’ email. Attach the signed checklist to the invoice for your records.

Keep a simple log of every commercial visit — dates, services, and manager sign-offs — so renewing the maintenance contract each year is a formality, not a negotiation.
