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.

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.
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

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.
