A March checklist before pressure washing season opens

The first mild weekends of March are when a pressure washing company finds out how ready it is. In the Sun Belt the pollen is already on the cars and the north walls of houses are turning green; further north there are a few weeks left, but not many. Thumbtack’s 2026 price guide tells homeowners that “mild days in spring or fall are ideal for power washing,” and it also tells them to hunt for discounts “during slower seasons, such as winter or early spring.” March is where those two pieces of advice meet: the last month customers expect a deal, and the first month the phone starts ringing.

Here is what we would want finished before it does.

Get reviews back inside the last three months

BrightLocal’s 2026 consumer review survey, published last month, is blunt about freshness. Seventy-four percent of consumers only care about reviews written in the last three months, and 47% will not use a business with fewer than 20 reviews. For a seasonal trade that is a trap. A company whose newest review came from a November deck job looks, to most of the people comparing it in April, like a company that may have closed.

The same survey found that 31% of consumers will only use a business rated 4.5 stars or higher, and it listed an appealing photo or video with the review among the trust factors that matter, at 36%. A wash company has an advantage there that most trades lack: the work photographs well.

• Ask every customer from the winter for a review this month: commercial accounts, the odd mild-weekend driveway, any window jobs you fitted in.
• Ask for a photo with the review, or text them yours to attach.
• Reply to every review, and name the surface and the neighborhood in the reply.

Fix the roof page before the algae calls start

Roof cleaning is the biggest ticket on Thumbtack’s list. Its guide puts the average roof at $419 to $686, against $241 to $418 for a house wash, and quotes a Texas owner saying soft washing generally costs more than pressure washing because of the machine and the solutions it needs.

It is also the job most likely to be described wrongly. The Asphalt Roofing Manufacturers Association’s technical bulletin on algae says the streaks can be lightened with a solution of chlorine bleach, trisodium phosphate and water, advises against scrubbing because the friction can loosen granules, and states that high pressure washing systems should not be used for algae removal.

Before the season, read your roof page and your roof photos against that bulletin.

• Call the service soft washing, and show it: low pressure, solution applied, rinsed off.
• Take down any photo of a surface cleaner or a pressure wand on shingles.
• Say how you protect plants and drains during a roof job, because the solution has to run off somewhere.

Write down where the water goes

Spring is when HOA boards and property managers start booking common areas, storefronts and parking lots, and they ask a question homeowners rarely do: where does the wash water go? Ohio EPA’s guidance from last June says power washing wastewater counts as industrial wastewater even when the soap is biodegradable, and that it cannot be discharged into a storm sewer. Brookhaven, Georgia prohibits washwater in its storm drains, with fines of up to $1,000 per violation per day and up to six months in jail, and the city notes that a roof job may require vacuuming the washwater. Sacramento County lists pressure washing discharge among its common stormwater violations.

“Eco-friendly” does not answer that question. A short, true description of your practice does: what you block, what you recover, and where it ends up. PWNA, the trade association, runs environmental training that teaches companies to document their practices for commercial clients, municipalities and inspectors, and that document is exactly what a property manager wants to see attached to a quote.

Plan the summer schedule now

Spring is the rush, but summer is where schedules quietly break. Thumbtack warns that direct summer sun can dry the cleaning agent before it gets rinsed off, so most crews move house washes into the morning. That has knock-on effects for marketing.

• The booking page should offer morning slots for house washes and keep afternoons for flatwork and shaded jobs.
• Search ads for house washing should run when a booking can actually be offered.
• Reminders to last spring’s customers should go out in May, before the calendar fills.

None of this needs doing in July. All of it is harder to set up once April is underway.

What to do this month

• Ask every customer from the last four months for a review, with a photo.
• Read the roof page against the ARMA bulletin and remove any high-pressure roof imagery.
• Write three sentences on how your crew handles wash water, confirm they are true on every job, and add them to the site and to commercial quotes.
• Set up separate search campaigns for house washing, flatwork, roofs and commercial work, each with a radius you can serve.
• Decide who answers the phone while the crew is working, before the first warm weekend.
• Put morning-only house wash slots on the booking page for June through August.

A wash company that walks into April with fresh reviews, an honest roof page and a clear answer on runoff has done most of the season’s marketing already. Our page for pressure washing companies shows how the year fits together, and our review work covers the request and reply routine.
