Quarterly Pressure-Wash Plan
The Quarterly Pressure-Wash Plan is four visits a year timed to the Pacific Northwest seasons that actually deposit the staining — late spring after the pollen drops, mid-summer before the deck takes heavy entertaining use, fall before the leaves pile on the walkways, and end-of-winter when the north-side moss is at its worst. Standard pressure on concrete driveways and walks, lower PSI with a wider nozzle on pavers and natural stone, soft-wash chemistry under 500 PSI on vinyl siding and painted-wood surfaces (anything stronger forces water behind the panel into the wall cavity). From $900 for the standard plan up to $2,400 for a premium multi-surface property with a two-story siding soft wash included once a year. One trip charge per visit, member labor rate on any add-on washing the tech does the same day.

What Does the Quarterly Pressure-Wash Plan Cover?
The Quarterly Pressure-Wash Plan is a four-visit annual program built for the Pacific Northwest weather year — each visit matches PSI, nozzle angle, and stand-off distance to the surfaces it cleans, with the calendar timed to the seasons that actually deposit the staining. Prices from $900 for a standard single-story property up to $2,400 for a premium multi-surface property with a two-story siding soft wash bundled in once a year. Each surface family fails a different way with the wrong setting, and the chemistry on the vinyl siding is what separates a clean wall from a wall with a hidden mold problem behind the panel.
Late Spring Visit — Pollen, Patio, Deck
Late April through late May, after the maple pollen and Douglas-fir candle drop. Patio and deck cleaning is the priority — a wood deck takes 500 to 1,500 PSI with a 40-degree nozzle and a wider stand-off (anything tighter gouges the wood and raises the grain), a composite deck takes 1,500 to 2,500 PSI with cleaning solution doing most of the work, a concrete patio cleans like a driveway. Lower siding on the south face gets a soft-wash inspection if pollen built up.
Mid-Summer Visit — Driveway, Walks, Entertaining Surfaces
Late June through July, before the deck and patio take heavy summer entertaining use. Driveway and walkway pass with the surface-cleaner attachment for consistent overlapping passes (random patterns leave streaks that show up two hours after we leave). Standard poured concrete at 3,000+ PSI with a 25-degree nozzle, stamped concrete or exposed-aggregate at lower PSI with a wider 40-degree nozzle and longer stand-off so the wand does not etch the pattern. Pavers get a re-sand of polymeric joint sand after the wash.
Fall Visit — Walkways, Fence Lines, Pre-Leaf-Drop
Late September through October, before the bulk of the leaves drop and pile on the walkways and lower siding. Walkway and front-entry surfaces cleaned first, fence lines (cedar, pressure-treated pine, vinyl) cleaned at 1,500 to 2,500 PSI with a 40-degree nozzle, heavy mildew on the shaded side gets a sodium-hypochlorite pre-soak with a five-to-ten-minute dwell before the wash. Garage apron and driveway re-touched if needed.
End-of-Winter Visit — North-Side Moss, Lower Siding Soft Wash
Late February through March, when the north-side mildew and moss on the driveway, walks, fence lines, and lower vinyl siding are at peak season. The lower vinyl-siding soft wash is the headline of this visit — sodium-hypochlorite cleaning solution at under 500 PSI dwells five to ten minutes, then rinses. The chemistry kills the algae and mildew; the rinse carries the dead organic matter away. The wall stays dry inside the cavity. Painted-wood siding gets the same soft-wash treatment.
Runoff Routed, Not Into a Storm Drain
Municipal storm-water regulations in Seattle, Bellevue, and most Puget Sound cities prohibit oil-stained runoff and surfactant-laden runoff from entering storm drains — that water reaches Puget Sound or Lake Washington untreated. On garage-floor passes, oil-stain treatments, and any wash using surfactant chemistry we block the relevant storm drain on the work-area side, contain runoff toward the sanitary apron or a vegetated buffer, and dispose of degreaser-soaked debris separately per local code.
How the Quarterly Pressure-Wash Plan Works
Five sequential steps from the seasonal visit calendar through the storm-water-safe rinse — the actual sequence we follow on every Handis Quarterly Pressure-Wash plan visit.
Seasonal Visit Calendar Locked at Plan Start
Four visit windows are scheduled at the start of the plan year — late spring (pollen, patio, deck), mid-summer (driveway, walks), fall (walkways, fence lines, pre-leaf-drop), and end-of-winter (north-side moss, lower siding soft wash). The exact dates flex by a week or two to catch the dry windows; the windows themselves do not move.
Surface Assessment & PSI Match Per Visit
At each visit the tech walks every surface before the wand turns on — concrete, pavers, natural stone, wood deck, composite deck, vinyl siding, brick, stucco, fence line — and matches the PSI, nozzle angle, and stand-off distance to the substrate. The truck carries a half-dozen nozzles for exactly this reason.
Surrounding Area Protection
Plants, exterior outlets, ground-floor windows, outdoor furniture, and cars get covered or moved before pressure starts. The wand kicks up debris, chemistry, and water droplets across a 20-foot radius — five minutes of prep avoids broken pots, soaked outlets, and angry-neighbor calls.
Soft Wash on Vinyl & Painted Wood — Chemistry Does the Work
Vinyl siding, painted-wood siding, and stucco clean at under 500 PSI with sodium-hypochlorite cleaning solution dwelling five to ten minutes. Standard pressure forces water behind the panel into the wall cavity and creates a mold problem worse than the one you started with — soft-washing keeps the substrate dry.
Overlapping Passes + Storm-Drain-Safe Runoff
Driveways, large patios, and concrete pads get consistent overlapping passes — never random patterns — so the slab dries uniformly. Streaks do not show up until two hours after we leave; the overlap technique prevents the same-evening callback. Runoff is contained per Seattle and Puget Sound municipal storm-water code.
Quarterly Pressure-Wash Plan Pricing
Final pricing depends on driveway and patio square footage, fence linear footage, deck surface area, house perimeter and story count for the soft wash, and whether stamped concrete or pavers require the wider-nozzle longer-stand-off technique. Members pay member labor rate on any add-on washing the tech does during a plan visit. Request a free estimate for an accurate annual quote.

Why Handis for the Quarterly Pressure-Wash Plan
Most pressure-wash subscription pitches load up the brochure with line items nobody ever needs and skip the boring chemistry that actually keeps the vinyl siding from growing mildew behind the panel. Our quarterly plan does the opposite — short visit list, real PSI match per surface, soft-wash chemistry where pressure would do damage, runoff routed away from the storm drain, four visit windows locked to the seasons that actually deposit the staining in the Pacific Northwest. Same crew, same notes, same opinion about whether a third moss pass is worth booking next year.
PSI matched to the surface — never one setting for the whole job
Standard concrete driveways handle 3,000+ PSI with a 25-degree nozzle. Wood decks need 500 to 1,500 PSI with a 40-degree nozzle and a wider stand-off — anything higher gouges the wood and raises the grain. Vinyl siding cleans at under 500 PSI with chemistry, not raw pressure. Pavers and natural stone need lower pressure to keep the joint sand in. We change settings between surfaces on the same visit; the truck carries a half-dozen nozzles for exactly this reason.
Soft-washing on vinyl and painted wood — chemistry does the work
Vinyl siding and painted-wood siding fail the same way under high PSI — water gets forced behind the panel into the wall cavity, paint strips off, and mildew comes back inside three months from the wet substrate behind the surface. Soft-washing uses sodium-hypochlorite cleaning solution at low pressure (under 500 PSI), dwells five to ten minutes, then rinses. The chemistry kills the mildew; the rinse carries it away. The wall cavity stays dry.
Visit calendar timed to PNW seasonal deposits
Late spring catches the pollen on the patio and deck. Mid-summer catches the driveway and walks before the entertaining season hits. Fall catches the walkways and fence lines before the leaf piles. End-of-winter catches the north-side moss and gets the lower vinyl siding back to clean before spring. The calendar bends to the weather — if a visit window catches a 10-day rain block we shift by a week to find the dry window. The four visits land; the dates flex.
Runoff routed correctly, not into a storm drain
Municipal storm-water regulations in Seattle, Bellevue, Redmond, and most Puget Sound cities prohibit oil-stained runoff and surfactant-laden runoff from entering storm drains — that water reaches Lake Washington and Puget Sound untreated. On garage-floor passes, oil-stain treatments, and any wash using surfactant chemistry we block the relevant storm drain on the work-area side, contain runoff toward the sanitary apron or a vegetated buffer, and dispose of degreaser-soaked debris separately per local code.
Insured, background-checked, 30-day workmanship guarantee
Every Handis handyman carries liability insurance and has cleared a background screening before the first job. If a surface we pressure-washed shows incomplete cleaning, visible streaks from inconsistent passes, or a return of mildew within 30 days because of inadequate chemistry or dwell time, we come back and re-treat at no extra charge. New oil drips, fresh debris from a windstorm, normal seasonal staining, or pollen from a late drop is outside the guarantee — we will tell you on arrival what the wash can realistically achieve.
Estimate
Tell us the driveway material (standard concrete, stamped, exposed-aggregate, pavers) and approximate square footage, the patio surface and size, the deck size and material (cedar, pressure-treated pine, composite), the house siding (vinyl, painted wood, brick, stucco) and story count, the fence linear footage, and whether you want garage-floor degreasing on the annual cycle. We will send back a clear annual estimate with the visit calendar.
Customer Reviews
Recent Quarterly Pressure-Wash Plan reviews from verified Seattle-area customers.
Quarterly pressure-wash plan on a property with a stamped concrete driveway and a cedar back deck. The tech used different settings for each surface every visit — wider nozzle and longer stand-off on the stamped pattern, lower PSI on the cedar, full pressure with the surface cleaner on the walkways. Four visits across the year, none missed, none with streaks. Driveway looks brand-new and we have not had to call anyone separately for the patio.
We bundled the quarterly plan with the once-a-year two-story siding soft wash. The vinyl on the north side of our house was covered in green algae and the tech soft-washed the whole exterior with low pressure and sodium-hypochlorite chemistry — said anything stronger would push water behind the panel. House looks like we just had it painted. The three follow-up wash visits across the year keep the driveway, deck, and front walk on a schedule.
Cedar fence going green on the shaded side. The fall visit included a sodium-hypochlorite pre-soak on the heavy-mildew sections, dwelled ten minutes, then washed at 1,500 PSI with a 40-degree nozzle. He also told us to wait 48 hours before staining and recommended a specific product. Following spring visit caught the front walk before leaf piles and we have not had to schedule a separate wash all year.
Pollen drop on the back patio every May was driving us crazy. The late-spring visit hit it right after the maple was done dropping — pavers cleaned at lower PSI to keep the joint sand in, polymeric sand swept back into the joints after the wash. Deck cleaned the same day with a wider nozzle on the cedar. Whole back was usable for entertaining the next weekend.
End-of-winter visit is the one that sold us on the plan. North-side driveway had been green-tinted since January and we did not want to wait until summer for a separate booking. Tech ran the surface cleaner with overlapping passes, soft-washed the lower vinyl siding while the chemistry dwelled, and routed all the runoff toward the sanitary apron because storm drains in our neighborhood feed straight into Lake Washington. House looked like spring four weeks early.
