Pressure washing is the rare side hustle that went viral for a reason, it actually works. The barrier to entry is a few hundred dollars, the skills take days (not months) to learn, and the before-and-after content practically markets itself on social media. This is not some internet-only hustle. You are providing a real service that real homeowners pay real money for, repeatedly.
The exterior cleaning industry generates over $10 billion annually in the US alone, and demand keeps growing as homeowners invest more in property maintenance. Here is exactly how to start, what to charge, and how to scale.
You use high-pressure water (and sometimes chemicals) to clean exterior surfaces: driveways, sidewalks, decks, fences, house siding, patios, commercial buildings, parking lots, and more. Grime, mold, mildew, algae, and years of dirt come off in minutes. The transformation is dramatic, which is why this content dominates social media.
Most successful operators offer both services, which lets you clean virtually any exterior surface a customer has.
This setup handles residential driveways, sidewalks, and decks. It is enough to start generating revenue immediately.
This setup handles everything. Residential, soft washing, and light commercial work. Most operators upgrade to this level within 2-3 months.
This is a full-time operation setup. You are now equipped to handle large commercial contracts.
The math is simple: if you do 3 jobs per day at an average of $250 each, that is $750/day. Work 5 days a week and you are at $15,000/month in gross revenue. Subtract fuel, chemicals, and equipment wear (roughly 15-25% of revenue), and you are netting $11K-$13K.
Do not overthink this step. Go to Home Depot or Lowes and buy a gas pressure washer in the $250-$400 range. The Simpson MegaShot 3,100 PSI is a popular starter choice. Grab a surface cleaner attachment if the budget allows.
Go home and wash your own driveway, sidewalk, and patio. Film the entire thing. Learn how different nozzle tips work:
Spend 2-3 hours practicing. You will feel confident quickly. This is not rocket science.
This is where pressure washing has a massive advantage over other service businesses. The content is inherently satisfying and shareable.
Post 1-2 videos per day from your jobs. Formats that work:

Do not try to be fancy. Raw, authentic footage outperforms polished content in this niche. The grime and the transformation are the stars, not you.
Add your city to every post caption. "Driveway transformation in [City, State]." This helps local people find you. Put your phone number and booking link in your bio. When a video goes viral (and it will eventually), you will get DMs from people in your area asking for quotes.
Pricing Strategy
How to Quote Jobs
The simplest method: charge by square footage.
- Concrete surfaces: $0.10-$0.25 per square foot
- House washing (soft wash): $0.15-$0.35 per square foot
- Deck/fence: $0.50-$1.50 per square foot (more labor-intensive)
- Roof soft wash: $0.20-$0.50 per square foot
A standard 2-car driveway is about 400-600 square feet. At $0.25/sqft, that is $100-$150. A 2,000 sqft house exterior at $0.20/sqft is $400.
Package Deals That Increase Revenue
Offer bundles: "Driveway + sidewalks: $175" or "Full exterior package (house wash + driveway + patio): $599." Bundles increase your average job value by 40-60% because customers perceive savings and you are already on-site.
When to Raise Prices
Raise prices when you are booking more than 5 days out. If you are turning down work, your prices are too low. Most operators undercharge in the beginning. Within 3-6 months, you should be at least 20-30% above your starting rates.
Scaling Beyond Solo Operator
Phase 1: Solo Operator ($2K-$8K/month)
This is where everyone starts. You do every job yourself. Focus on efficiency: how many jobs can you complete per day without sacrificing quality? Optimize your route to minimize drive time between jobs.
Phase 2: Hire a Helper ($8K-$15K/month)
Once you are consistently booked 2+ weeks out, hire a part-time helper at $15-$20/hour. Your helper handles the actual washing while you run the business side: quoting, scheduling, marketing, and customer communication. You can also run a second job simultaneously.
Phase 3: Multiple Crews ($15K-$30K+/month)
Add a second truck and crew. You stop washing entirely and focus on sales, marketing, and operations. Each crew generates $3K-$6K/week in revenue. Your profit per crew after labor and expenses is typically 30-40%.
Common Mistakes to Avoid
Starting with too expensive equipment. A $300 machine makes money just as well as a $3,000 machine when you are starting. Upgrade with revenue, not savings.
Not getting insurance. One damaged window, one cracked driveway, one slip-and-fall on a wet surface, and you are paying out of pocket. General liability insurance is $30-$50/month. Get it before your first job.
Ignoring soft washing. Pressure washing alone limits your services. Soft washing (low pressure + chemicals) for house siding, roofs, and delicate surfaces doubles your potential revenue. Learn it within your first month.
Undercharging. New operators constantly undercharge because they feel guilty or unsure. Your time, equipment, fuel, insurance, and expertise have value. Charge what the market supports, not what feels comfortable.
Not asking for reviews. Every single completed job should end with: "If you are happy with the work, I would really appreciate a Google review. It helps my small business a lot." Hand them a card with a QR code linking to your Google review page. Reviews are the lifeblood of local service businesses.
Ignoring where the water goes. Wash water carrying detergent, dirt or paint residue is not permitted to enter a storm drain in most jurisdictions. Storm drains generally discharge untreated to surface water, and contractors are expected to contain, recover and dispose of runoff appropriately. Check your local rules before your first job; this is the compliance issue most likely to catch a new operator.
Washing in the wrong order. Always wash from top to bottom. Start with the highest point and work down so dirty water does not run over clean surfaces. This sounds obvious but beginners get it wrong constantly.
Chemical Knowledge: What Separates Amateurs from Pros
Understanding cleaning chemicals is what takes you from "guy with a pressure washer" to "professional exterior cleaning service."
Sodium hypochlorite (SH): The base chemical for most exterior cleaning. It is essentially strong bleach. Used in soft wash mixes for house washing, roof cleaning, and mold/mildew removal. Buy it in bulk from chemical suppliers, not retail bleach.
Surfactant: Added to SH to help the chemical cling to surfaces and penetrate grime. Without surfactant, your chemical slides right off vertical surfaces.
Sodium hydroxide: A strong degreaser for oil stains, restaurant grease, and heavy organic buildup. Handle with care, it is caustic.
Oxalic acid: Used for rust stain removal and wood brightening after cleaning.
Standard house wash mix: 1-2% SH solution with surfactant, applied at low pressure, left to dwell for 5-10 minutes, then rinsed. This kills mold, mildew, and algae on contact and makes the surface look brand new.
Realistic Timeline
Week 1-2: Register the business, check licensing, buy equipment, practice, set up online presence. Zero revenue. Licensing is not optional in every state: Virginia requires a Class C contractor licence under § 54.1-1100 above its stated job and annual value thresholds, and California's CSLB exemption under Bus. & Prof. Code § 7048 stops at $1,000 per job and is lost entirely once you advertise as a contractor or employ a helper.
Week 3-4: First 3-5 paid jobs. Revenue: $500-$1,500.
Month 2: Booking 2-3 jobs per week from Google, social media, and referrals. Revenue: $2,000-$4,000.
Month 3-4: Consistent bookings, raising prices, repeat customers. Revenue: $3,000-$6,000/month.
Month 6: Full part-time income, considering going full-time or hiring help. Revenue: $5,000-$10,000/month.
Year 1: Established business with reviews, referrals, and recurring commercial contracts. Revenue potential: $8,000-$15,000+/month.
This is not a get-rich-quick scheme. It is a real service business that rewards showing up, doing good work, and building a reputation in your community. The difference between this and most side hustles is that demand is proven, the skills are learnable in days, and every job you complete generates content that markets your business for free.
Lead Paint: The Certification Most Pressure Washers Do Not Know They Need
This is the single most overlooked legal exposure in exterior cleaning, and it applies to a large share of the housing stock.
What the rule says
In 1978 the federal government banned the sale of lead-based paint for homes, childcare facilities and preschools. The EPA states that approximately three-quarters of US homes built before 1978 still contain some lead-based paint.
The EPA's Renovation, Repair and Painting Rule requires that anyone paid to perform work that disturbs painted surfaces in homes, childcare facilities and preschools built before 1978 be certified, with employees trained in lead-safe work practices, either as certified renovators or on the job by one.
Read that against what you do. Pressure washing a painted exterior disturbs painted surfaces. On a pre-1978 house with lead paint, high-pressure water removes paint and disperses it as chips and dust across the surrounding soil and the neighbouring property.
The rule generally does not apply to homeowners working on their own pre-1978 homes. It does apply where the property is rented, and it applies to you because you are being paid.
Why this matters commercially, not just legally
Penalties are assessed per day, and reported figures for the current maximum run into tens of thousands of dollars daily. This is not a fine you absorb as a cost of doing business.
Your insurer may decline the claim. A pollution or contamination exclusion is standard in general liability policies, and lead contamination of a property is exactly the kind of claim that meets one.
The homeowner carries consequences too, which makes this a conversation they will want to have if you raise it and a grievance if they discover it later.
What to do
Establish the build year before quoting. It takes seconds from public records and it is the single question that determines your obligations on that job.
Get certified if you intend to work on older housing. The training is short and inexpensive relative to the work it unlocks, and in much of the country pre-1978 housing is the majority of the residential stock.
Where you are not certified, decline the work and say why. A homeowner told that their house needs a lead-safe certified operator generally respects it, and it is a strong differentiator against the competitor who did not know.
Consider whether soft washing is the better method anyway. Low-pressure chemical cleaning removes organic growth without stripping paint, which is better for the substrate and reduces the disturbance the rule is concerned with. It does not remove your obligations, and it does change the risk profile of the job.
Where the Water Goes
The second regulatory issue is the one your runoff creates, and pressure washing produces far more of it than any other cleaning trade.
The rule
Wash water on a paved surface picks up detergent, oil, grease, heavy metals and whatever you just removed from the building, then flows to the nearest storm drain and from there, in most systems, to a watercourse without treatment.
North Carolina's Department of Environmental Quality states the position clearly in guidance written for mobile cleaning operations and vehicle service businesses: any cleaning operation that causes or contributes to a water quality standard violation may be held liable and subject to penalties under state law, and discharging to storm drains may violate local ordinances and result in enforcement action by local authorities. The framework behind that is federal, and municipalities layer their own stormwater ordinances on top.
The jobs where this bites hardest
Pressure washing has categories of work that are far more sensitive than a driveway.
Restaurant and commercial kitchen exteriors. Grease-laden runoff is among the most heavily regulated discharge in this trade, and these are also among the best-paying recurring contracts. Doing them properly requires containment and recovery, not a hose and a drain.
Fleet and equipment washing, for the same reason.
Anything removing paint or coatings, which produces solids you are responsible for capturing, and which connects directly to the lead paint section above.
Parking structures and garages, where accumulated oil and metals concentrate.
Working compliantly
Know where the drains go. A site walk before quoting should identify every drain in the work area and whether it is storm or sanitary.
Block and recover on sensitive jobs. Drain mats, berms and a vacuum recovery system are real equipment with real cost, and they are what makes commercial work available to you.
Discharge recovered water to sanitary sewer with permission, not to the nearest gutter. Many municipalities permit this and some require an agreement first.
Prefer methods that reduce runoff volume where the job allows it.
Ask your municipality directly. Stormwater programmes publish guidance for exactly this trade, and a written answer is worth having.
Turn it into a selling point
The competitor charging less is almost certainly discharging to the storm drain. That is a liability for the property owner, and for a commercial client it is a compliance problem on their site under their permit.
Being the operator who can explain, in writing, how you contain and dispose of wash water is what opens restaurant groups, property managers and municipal contracts. It is the same dynamic described in this site's mobile detailing guide and it is worth more here, because the volumes are larger and the clients are more sophisticated.
Damage Liability, and the Insurance That Actually Responds
A pressure washer is a tool that removes material. Pointed at the wrong surface, at the wrong pressure, it removes material the owner wanted to keep, and the bill lands on you.
What actually gets damaged
Wood. Softwood decking and siding furs and gouges under pressure, and the damage is permanent and immediately visible.
Mortar and older brick. Pressure strips mortar from joints, and repointing costs far more than the wash.
Roofs. Pressure washing asphalt shingles removes the granules that constitute the weather surface. This is the single most expensive mistake in the trade and it is why soft washing exists for roofs.
Window seals and glazing. Water driven into a failed seal fogs a double-glazed unit, and the owner discovers it weeks later.
Painted and stained surfaces, which connects to the lead paint section above.
Landscaping. Chemical run-off kills planting, and this is the most common small claim in residential work.
Interiors. Water driven under siding, through vents or around door frames produces damage the owner finds after you have gone.
The insurance that matters
Three covers, and the distinction between them is where operators get caught.
General liability responds when you injure someone or damage property. It is the baseline and it is inexpensive.
Care, custody and control. This is the one that responds to damage to the thing you were working on. Standard general liability frequently excludes property in your care, and the property in your care is the entire house. Ask the question in those words and get the answer in writing.
Pollution liability. Given the runoff and chemical discussion above, a contamination exclusion in a general policy is a real gap for this trade specifically. Ask whether chemical or wash-water discharge claims are covered.
Add commercial vehicle cover, because a personal auto policy will not respond to a claim involving a working vehicle, and workers compensation the moment you employ anyone.
The habits that prevent claims
Photograph everything before you start. Every elevation, close-ups of anything already damaged, timestamped. Pre-existing damage is the most common dispute in this trade and photographs end it in seconds.
Test in an inconspicuous area on any surface you have not cleaned before, at the lowest effective pressure.
Walk the property with the customer first and name what you will not do. Declining to pressure wash a roof, and explaining why, marks you as someone who knows the trade.
Cover and rinse planting before and after chemical application.
Match the method to the surface rather than to the schedule. Almost all damage in this business comes from using too much pressure to save time.
Put the exclusions in the quote. What you will clean, what you will not, and what result is realistic on a surface that is stained rather than dirty.
Chemicals Are the Skill, and the Other Liability
The section above on chemical knowledge is right that it separates operators. Two additions on the risk side.
Sodium hypochlorite is the workhorse and it is not benign. It damages planting, corrodes metal, discolours fabric and stains concrete if allowed to dry unevenly. Dilution ratios and dwell times are the craft of this trade, and the difference between a clean surface and a damaged one is frequently a mixing decision.
Never combine cleaning chemicals. Mixing hypochlorite with an acidic cleaner produces chlorine gas. This is the genuine physical danger in the trade and it happens when operators improvise on site.
Read and keep safety data sheets for everything you carry. If you employ anyone, providing them is an obligation, and having them available is what a commercial client's health and safety process will ask for.
Personal protective equipment is not optional with high-pressure equipment and concentrated chemicals. Eye protection in particular, and note that a high-pressure injection injury to the hand is a surgical emergency that looks trivial for the first hour.
Commercial Work Is Where the Business Actually Scales
Residential pays the bills in year one and it has a ceiling. Every job is a new sale, the season is short, and the customer buys once a year at most. Commercial changes all three.
Why commercial is structurally better
It recurs on a schedule. A restaurant needs its exterior and bin area cleaned monthly, a property manager needs walkways quarterly. That converts selling into servicing, which is the same shift described in the mobile detailing guide on this site and it matters more here because job values are larger.
Jobs are bigger and travel is amortised. One shopping centre is a day of work at one address rather than six driveways across a city.
Buyers are less price-sensitive and more compliance-sensitive. A property manager cares about your insurance certificate, your runoff handling and whether you will create a problem on their site. Those are things you can be better at, unlike price.
The season is longer. Commercial cleaning is driven by contract and appearance standards rather than by weather and homeowner mood.
The categories worth pursuing
Food service. Kitchens, bin areas, drive-throughs and the pavement outside. High recurrence, genuinely unpleasant, and priced accordingly. Requires the runoff capability described above, which is precisely why it pays.
Property management. Apartment complexes, office parks and retail centres. One relationship produces many sites.
Fleet and equipment. Trucks, trailers and plant, subject to the same discharge rules as vehicle washing.
Municipal and institutional. Schools, councils and public facilities. Slow procurement, reliable payment, and a certificate requirement you must be ready for.
How to win it
Lead with compliance, not price. Your opening should establish insurance, runoff handling and scheduling reliability. The competitor is quoting a number; you are removing a risk.
Ask for one site as a trial. A single building at a fair price is a small decision for a manager, and results are visible immediately in a trade where before-and-after is the product.
Turn up when you said. Commercial contracts are lost on reliability far more often than on quality, because the work is fairly standardised and the scheduling is not.
Invoice properly. Net terms, purchase order references and a proper invoice. Sole traders who cannot invoice the way a finance department needs do not get renewed regardless of how clean the building is.
Get on the approved supplier list. Once you have cleared insurance and compliance checks for one property manager, ask what it takes to be added formally. That is the point at which work starts arriving without a sale.
Who Should Skip This
If you cannot do sustained physical work outdoors, this is hours of standing, dragging hose, working at height on ladders and handling equipment in weather. It is harder on the body than the equipment cost suggests.
If you will not carry proper insurance, the damage exposure described above is uninsured and a single roof claim exceeds a year of profit.
If you want year-round even income, note that residential work collapses in winter in most climates. The commercial and interior work above is the answer, and it takes time to build.
If you are not willing to learn the chemistry, you will damage something. The pressure is the easy part; knowing what to apply, at what dilution, for how long, on which substrate, is the trade.
If you want to be absent from the work, note that hiring in this business is difficult precisely because an inexperienced operator with a pressure washer can cause thousands in damage in a minute.
What it offers is genuinely good: low startup cost relative to the revenue, immediate cash, visible results that sell themselves, no inventory, no platform between you and the customer, and demand that exists in every populated area regardless of economic conditions. The compliance work described on this page is what separates a business from a truck with a machine in it, and it is also what makes the better clients reachable.
Where This Goes Next
Three judgements about direction, offered as reasoning rather than forecast.
Stormwater enforcement tightens rather than relaxes. Municipal programmes have expanded steadily and mobile cleaning is an obvious and visible target. Operators already containing and recovering will find this an advantage; operators discharging to the gutter will find it an existential problem.
Soft washing continues displacing high pressure on residential exteriors. It damages substrates less, it handles organic growth better, and it reduces the paint disturbance the RRP Rule is concerned with. The equipment and the chemistry are worth learning now.
The work itself is immune to automation. Nothing about cleaning a specific building at a specific address is threatened by software, which distinguishes this from most of the income routes on this site. What competes with you is other people with machines, which means the durable advantages remain route density, recurring contracts and being the operator a property manager trusts on their site.
One thing to sort out in week one
Establish, in writing, what your general liability policy says about damage to the property you are working on, and about chemical or wash-water discharge.
Most new operators buy the cheapest general liability available, assume it covers them, and never read the exclusions. The two gaps described above are both standard, both quietly fatal, and both cheap to close if you ask before the first job rather than after the first claim.
