Pressure Washing Seasonal Playbook

How the pressure washing year runs

Temperature sets this calendar. In colder regions, freezing weather ends the season: runoff turns to ice on driveways and steps, and water left in a pump can crack it. The first warm weekend starts it again, usually all at once.

Note: This calendar assumes winters cold enough to stop washing for weeks. In mild climates, treat your slowest stretch as winter, and slide the seasons to match when your phone got busy last year.

Spring: book the rush before it starts

The spring rush rewards the owner who booked it in February. Once warm weather arrives, calls come in faster than you can return them, and a calendar filled in the order people called sends your trailer across town and back all day.

Start with last year's customers

Your easiest spring jobs are houses you've already washed. In late winter, send each past customer what you did, when, and a photo of the result, and offer them first pick of dates before you open the calendar to new callers. That annual reminder is how a one-time house wash becomes a yearly customer; how to get more pressure washing customers covers reminders and marketing around the jobs you book.

Book by neighborhood

A wash rig is slow to move: a trailer or skid, a water tank, and hose to roll out and back up at every stop. When a returning customer books, offer two or three dates when you'll already be nearby, and fill each day's route before you open a new one. Quote spring cleanups for salt-stained commercial entrances and sidewalks in winter too, so that work is booked before the residential rush.

Check prices before you book

Every job you book in February at last year's price carries this year's chemical, fuel and labor costs. Review your minimum job charge and your house, flatwork and roof prices before the first reminder goes out, using how to price pressure washing jobs. Large jobs booked weeks ahead are a reasonable place for a deposit; the contractor deposits guide covers how much to ask for and what to put in writing.

Example: Suppose you and a helper can finish 3 house washes on a full day, and between mid-March and the end of May you expect about 40 days dry and calm enough to work. That spring holds roughly 120 house washes. If 80 of last year's customers rebook in February, two thirds of the spring is spoken for before the first warm weekend, and new calls fill the gaps around your routes instead of setting them.

Plan for rain, wind and pollen

Set your weather rules before the calendar fills:

• Rain dilutes a soft wash mix and rinses it off before it works, so soft washing waits for a dry day. Light rain may not stop flatwork, but it delays any sealing that follows.
• Wind carries mist and mix onto cars, windows, plants and the neighbor's house. Decide when the crew stops spraying chemicals, and stick to it.
• Pollen, where it's heavy, can coat a freshly washed house again within days. Tell customers when they book, and either schedule those washes after the heaviest pollen falls or offer a follow-up rinse at a set price.

Keep a list of customers whose dates are flexible, so you know whom to call when a rain day opens a slot. Put the policy in writing: how to write a pressure washing estimate covers scheduling terms, and how to invoice pressure washing jobs covers weather reschedules. If your reschedules live in a pile of text threads, Redline, chat-first field service software, includes scheduling for moving jobs when the forecast changes.

The day before each job, text a prep list: close windows, move cars, bring in pet bowls and cushions, unlock gates, and point out cracked trim, loose paint or chalky siding so you can photograph it first.

Summer: heat, dwell time and plants

Heat changes three things: how your mixes behave, how plants handle runoff, and how long a crew in rain gear can safely work.

Keep the mix on long enough to work

On a hot wall in direct sun, a soft wash mix can dry before it has done its job, leaving streaks or spots on windows, trim and siding.

• Follow the shade: west-facing walls in the morning, east-facing walls in the afternoon, the sunniest walls as early or late as you can.
• Work smaller sections and rinse each one before the mix dries.
• Follow the product label for how long the mix stays on, and rinse glass as you go.
• Put house and roof soft washes in the cooler hours and flatwork at midday, since a surface cleaner leans more on pressure than on dwell time.

Check each sodium hypochlorite (bleach) label for storage temperature and directions, store it in the shade and buy amounts you'll use soon; if a mix stops working at your usual ratio, suspect an old jug before you add more chemical. In a dry summer, check whether your water utility restricts washing buildings or hard surfaces.

Protect plants every time

Every house wash drains into the beds below it, and on hot days that runoff lands on plants that are already stressed. Make protection a routine:

1. Walk the property with the customer and note prized plants, vegetable gardens, ponds and pools.
2. Soak beds and shrubs before you start, and keep them wet while you work.
3. Rinse plants thoroughly after each side and again before you leave.
4. Cover delicate and edible plants, and uncover them as soon as you finish; plastic left over plants in full sun can overheat them.
5. Photograph the beds before and after.

Write the plan into the estimate, including anything you'd like the customer to do first, such as watering the beds the evening before.

Decks and fences

Customers want decks and fences cleaned before they stain or seal. Wood is softer than it looks: too much pressure, or a narrow nozzle held close, can fuzz the grain or carve lines into the boards. Clean wood at low pressure with a cleaner made for it, and if the customer plans to stain, tell them the wood has to dry first and point them to the stain maker's instructions.

Keep the crew safe in the heat

Rain suits, chemical-resistant gloves, boots and goggles keep chemicals off skin and out of eyes, and they trap heat. Start at first light and finish roofs and the hottest walls before midday. Carry more cold water than you think you need and set up a shaded break spot. New workers carry the most risk: OSHA says more than 70 percent of heat-related deaths happen during a worker's first week, almost half of them on the first day, and its guidance is to start new and returning workers at 20% of the usual time in the heat on day one, adding no more than 20% each day ¹. Ease new helpers in that way, and agree on who calls for help and how you'd get someone off a roof if they get sick. Hiring your first pressure washing employee covers the chemical, ladder and equipment safety training a helper needs before peak season.

Fall: gutters, leaves and next year's contracts

Fall pays twice: the cleanup work in front of you, and the commercial work you sign for next year. In colder markets, book fewer jobs per day as the days shorten and frost delays morning starts. Remind customers who host for the holidays in early fall, since the last weeks of the season disappear once nights start freezing.

Gutters and leaf stains

Gutters are a natural fall add-on, and they're ladder work:

• Clear debris first, then wash the gutter faces if the customer wants the black streaks gone.
• Set ladders on firm, level ground, keep three points of contact, and move the ladder instead of reaching.
• Don't run a pressure washer from a ladder. The wand pushes back when you pull the trigger, and that can throw you off balance. Use extension wands or telescoping poles from the ground.
• Inspect ladders before the season and retire any with bent rails, cracked rungs or worn feet.

Wet leaves left on concrete can leave tannin stains. Schedule driveways and patios after most leaves are down, or warn the customer that falling leaves can stain again. Price stain treatment as its own line item, and say in the estimate that some stains may not fully lift.

Sign next year's commercial work now

Ask each HOA board, property manager and commercial customer when they set next year's budget, and get your proposal in before that date. Propose a schedule that spreads work across the year, such as quarterly flatwork, an annual building wash and monthly dumpster pads and drive-thrus where your climate allows. Ask now what they need to set you up as a vendor, such as a certificate of insurance and a W-9, so paperwork doesn't hold up your first invoice.

If you'll offer holiday lighting, start selling it to house wash customers in late summer, while you're still on their property.

Winter: stop washing safely and find work that fits

Know when to stop

The problem with winter washing is the water left behind. Runoff freezes on driveways, steps and walks, and a job that looks fine at noon can leave ice on the front steps by evening, with shaded areas frozen longest. Set a simple rule, such as no washing when tonight's forecast low is below freezing, and tell customers in advance what happens to jobs that land on those days.

Winterize the rig

Water left inside equipment can freeze overnight and crack parts:

• Drain the pump, hoses, reels, guns, wands, surface cleaners, buffer tank and trailer plumbing, then protect the pump the way its manufacturer recommends, usually with pump antifreeze or a pump protector.
• On hot-water units, drain or protect the heating coil as the manual directs.
• On any fall or spring night with a freeze in the forecast, drain the lines or park the rig somewhere heated.
• Follow the engine manual for off-season storage.
• Check chemical labels for storage temperatures, and keep bleach away from acids and ammonia-based cleaners: bleach mixed with an acid cleaner can release chlorine gas ², and with ammonia, chlorine or chloramine gas ³.

Keep engines and burners outside

Winter tempts crews to wash inside garages, warehouses and parking structures. Gas engines and fuel-fired burners give off carbon monoxide, which you can't see or smell. CDC says never to use a gasoline-powered pressure washer in an enclosed space or less than 20 feet from any window, door or vent ⁴. Keep burners outside too, unless the equipment's manual allows indoor use and the space has the ventilation it requires.

Work that fits winter

Holiday lighting uses what you already have (ladders, a truck, a customer list) in your slowest months:

• Sell the season as one package: design, install, a service call if a strand fails, takedown, and storage if you offer it. Collect at booking.
• Use clips that hold lights without nails, screws or staples through shingles, gutters or trim.
• Use outdoor-rated lights and cords, plug into outdoor outlets with ground-fault (GFCI) protection, and leave new outlets, circuits or hardwired timers to a licensed electrician.
• Ask your insurance agent whether your policy covers roof and ladder work and holiday decorating, and get the answer in writing.

Example: Suppose a roofline install takes two people half a day, and takedown takes another half day. If a two-person crew day costs you $800 in wages, payroll costs, truck and fuel, labor alone is $800 for the season, before lights, clips, a service call and storage. Price the package to cover all of it plus your margin.

Commercial work in mild climates. Where winter stays above freezing most days, keep commercial routes running: drive-thrus, dumpster pads, sidewalks, storefronts and parking areas, often at night or before opening. These jobs carry grease and oil, so plan how you'll recover or divert the washwater before you quote; how to start a pressure washing business covers washwater rules. In colder markets, keep a short-notice list for mild spells.

Moss and algae treatments. If you add these in a wet, mild climate, first ask your state's pesticide regulator whether applying them for hire requires a license, and follow the product label exactly.

Rebuild before spring

Use the slow weeks for the maintenance that never fits in May:

• Service or rebuild the pump on the manufacturer's schedule.
• Replace worn nozzles; as the opening wears, pressure drops and every job slows.
• Replace hoses with bulges, cuts or worn covers, along with damaged fittings, quick-connects and O-rings.
• Service the unloader, surface cleaner swivel and chemical pump, and check trailer tires, lights, brakes and tank straps.
• Stock spare parts, because in spring a two-day wait for a part costs two days of jobs.

Winter is also when to train a new hire on surfaces, mixes and safety, review last year by month (jobs, revenue, rain days lost, services sold), set prices and write the late-winter reminders.

Cash flow across the year

Revenue bunches into the warm months, but truck and trailer payments, insurance, phone, storage and your own pay come due every month. List last year's revenue and gross profit by month next to your fixed costs, and mark where gross profit falls short. That shortfall is your winter bill.

Example: Suppose your fixed costs (truck, trailer, insurance, phone, software and your own pay) are $6,000 a month. From December through February, commercial visits on mild days bring in $3,000 a month in gross profit, leaving a $3,000 gap each month, or $9,000 for the winter. Setting aside $1,000 from each of the other 9 months covers it before the slow months start.

Then shrink the gap:

• Sign recurring commercial work that runs through winter where your climate allows, billed monthly or quarterly.
• Sell holiday lighting prepaid, and keep part of that fall cash for January takedowns.
• Take deposits on large spring jobs you book in winter, within any limits your state sets.
• Buy equipment and do big rebuilds with summer money, not on a credit card in March.
• Invoice the day each job is done, and check money in and out weekly in the slow months. Cash flow explains why a strong summer can still leave the account thin in February.
