How much should I charge per square foot for pressure washing?

Residential driveways typically range from $0.15-$0.40 per square foot, while house siding runs $0.30-$0.60 per square foot. Concrete surfaces like driveways average $0.20-$0.30, while delicate surfaces like wood decks command $0.40-$0.70 due to the care required. Always factor in surface condition, accessibility, and local market rates.

What's the difference between soft washing and pressure washing?

Soft washing uses low-pressure water (under 500 PSI) combined with specialized cleaning solutions to remove organic growth, ideal for roofs, siding, and painted surfaces. Pressure washing uses high-pressure water (1,500-4,000+ PSI) for hard surfaces like concrete and brick. Choosing the wrong method can damage surfaces or leave cleaning incomplete.

How do I estimate pressure washing jobs accurately?

Measure the surface area using photos and satellite imagery, then multiply by your per-square-foot rate for that surface type. Add time estimates for setup, travel, and breakdown. Factor in surface condition (light dirt vs. heavy staining), accessibility (first floor vs. second story), and any special requirements like chemical treatments or multiple cleaning passes.

What PSI do I need for different surfaces?

Concrete and brick can handle 3,000-4,000 PSI. Vinyl siding requires 1,300-1,600 PSI. Wood decks need just 500-600 PSI to avoid splintering. Asphalt shingle roofs should be cleaned with under 500 PSI (soft wash method). Always test in an inconspicuous area first and start with lower pressure.

When should I use hot water vs. cold water?

Hot water excels at removing oil, grease, and stubborn organic stains, making it ideal for commercial kitchens, gas stations, and heavily soiled driveways. Cold water is sufficient for most residential work including house washing, deck cleaning, and light concrete cleaning. Hot water units cost more but can command premium pricing for specialized work.

What chemicals are safe for different materials?

Sodium hypochlorite (bleach) diluted to 1-3% is safe for most hard surfaces and kills organic growth. Use pH-neutral cleaners for aluminum and painted surfaces to prevent oxidation. Avoid acids on concrete unless specifically removing rust or efflorescence. Always rinse thoroughly and test new chemical combinations on small areas first.

How do I avoid damaging wood decks or siding?

Use low pressure (500-800 PSI), maintain a 12-15 inch spray distance, and keep the nozzle moving constantly. Use a 25-40 degree nozzle tip, never a zero-degree tip. Spray with the grain on wood, and avoid holding the stream in one spot. Pre-wet plants and rinse them immediately after if using chemicals.

Should I offer roof cleaning or focus on concrete?

Roof cleaning typically offers higher profit margins ($300-$800 per job) but requires specialized soft-wash equipment and carries more liability. Concrete work has higher volume potential and is easier to start. Many operators begin with concrete to build cash flow, then add roof cleaning as a premium service once they've mastered the basics and secured insurance.

Can I pressure wash in winter temperatures?

Work is possible above 40°F, but below freezing creates safety hazards from ice formation. Cold water is less effective at cleaning, and equipment can freeze if not properly winterized. Many operators shift to indoor work (garage floors, warehouses) or focus on estimates and equipment maintenance during the coldest months.

How do I manage spring season demand spikes?

Book jobs 2-3 weeks out during peak season and implement deposit requirements to reduce no-shows. Batch similar jobs by location to maximize daily capacity. Communicate longer lead times clearly and consider premium pricing for last-minute bookings. Train backup crew members before the season starts to handle overflow.

What's the proper dilution ratio for downstream injection?

Most downstreaming injectors pull at a 10:1 ratio (10 parts water to 1 part chemical). If using 12.5% sodium hypochlorite, this delivers approximately 1-1.5% solution at the surface, ideal for house washing. Stronger concentrations (3-5%) are needed for heavily stained concrete. Always confirm your injector's actual draw ratio as they vary by model.

How do I soft wash a roof without damaging shingles?

Apply cleaning solution from bottom to top using low pressure (under 300 PSI), let it dwell for 10-15 minutes, then rinse gently from top to bottom. Never use a pressure wand directly on shingles. Protect gutters and landscaping with tarps and pre-wetting. Schedule roof cleaning on overcast days when possible to prevent rapid drying.

Should I invest in a hot water pressure washer?

Hot water units cost $3,000-$8,000 more than cold water but allow you to charge 25-50% more for heavy-duty work like commercial kitchens, fleet washing, or oil-stained driveways. If your market has commercial demand or you regularly encounter grease and oil, the investment pays off within 20-30 jobs. For residential-only work, cold water is usually sufficient.

What GPM rating do I need for commercial work?

Residential work runs well on 2.5-3.5 GPM, while commercial jobs benefit from 4-5+ GPM for faster cleaning of large areas. Higher GPM reduces total job time significantly—a 5 GPM machine can clean a large driveway in half the time of a 2.5 GPM unit. Balance your budget against the size of jobs you're targeting.

Is a surface cleaner attachment worth the investment?

Absolutely. A quality surface cleaner ($200-$600) reduces driveway cleaning time by 70% and eliminates streaking from wand cleaning. It pays for itself within 5-10 jobs. Choose a size appropriate to your machine's GPM—typically 16-20 inches for residential work. This tool is essential for professional, even results on flat surfaces.

How do I price driveway vs. house siding differently?

Driveways are typically priced lower per square foot ($0.15-$0.30) because they're faster to clean and use simpler techniques. House siding commands higher rates ($0.30-$0.60) due to the care required, vertical work, and often soft-wash chemicals needed. Factor in time for protecting landscaping and windows when pricing house washing.

What's a typical profit margin for pressure washing?

Well-run pressure washing businesses maintain 40-60% gross profit margins after equipment costs, chemicals, fuel, and labor. Residential work typically yields 50-55% margins, while commercial contracts may run 40-45% due to competitive bidding. Specialty services like roof cleaning or deck restoration often exceed 60% margins.

What services can I offer during the off-season?

Interior concrete work (garage floors, basements, warehouses) continues year-round in most climates. Offer winter pricing promotions for exterior work on warmer days. Use slow periods for equipment maintenance, marketing campaigns, and booking spring work. Some operators add complementary services like gutter cleaning, window washing, or holiday light installation.
