Greens at Ridgecrest driveways are short, broom-finished builder concrete poured between 1999 and 2016, and most of them sit inside sprinkler range of Ridgecrest Golf Club's irrigation. That combination — untreated pressurized irrigation water, iron-heavy turf fertilizer, and geese working the ponds — puts three different stains on the same slab.
Almost every slab we wash in this neighborhood has some mix of the same three problems. Orange fan-shaped streaks near the driveway edge are iron from pressurized irrigation water, not dirt — that's a chemical stain sitting in the pores. Gray-green film on the north side of the house and on the pond-side walkway is algae, which loves shade plus constant sprinkler mist. And the dark blotches on back patios are goose droppings off the Ridgecrest ponds, which go acidic as they break down and bond to the surface. Straight pressure handles the algae and the general traffic grime. The iron needs an acid treatment before the wand ever touches it, and the goose mess needs to be soaked and lifted rather than blasted. We sort out which is which before we quote, because they aren't the same job.
Worth knowing before you spend money. Iron staining from irrigation water will not come out with pressure — you can wash a driveway until the concrete lightens around it and the orange is still there, just more obvious. It takes an oxalic treatment, and even then, a slab that's been getting hit by the same sprinkler head for fifteen years may only go to a faint shadow. Same story with goose droppings that sat through a winter: we can remove everything organic, but if the acid already etched the surface, the lighter patch is permanent texture, not dirt. Older late-90s pours in this subdivision sometimes have spalling — flaking surface where the top layer is already failing. We back the pressure off those or skip them, because blasting a spalled slab takes more of it off. If we think you'll be disappointed, we say so at the quote instead of after.
Lots here run around a tenth of an acre, so the driveways are short and the walkways are narrow, and there's rarely more than three to five feet between your slab and the neighbor's siding. That matters for pressure washing more than for windows. We keep the wand angled away from vinyl siding and off the mortar and window seals, and we sweep runoff toward the street rather than under a fence into somebody else's landscape rock. If you're on a lot backing the common-area path, be aware that the shared concrete is usually the HOA's to schedule, not yours — we're happy to wash it, but that call needs to come from the association. Plenty of homeowners here have us do driveway, front walk and back patio in one trip since none of the three is large on its own.
Pressurized irrigation in Nampa generally comes on around mid-April and shuts down in October, and that window is when the iron staining and the algae both build. Washing in late March feels satisfying and then the sprinklers start over. If your main complaint is the orange streaking, the better play is a wash after shutoff in October — the slab stays clean through winter and you go into spring looking good. If it's algae and general grime you're after, spring works fine. The other timing note specific to this pocket: the course runs fertilizer and spray cycles through the growing season, so a patio right off the fairway will pick up fresh residue days after a treatment. We'd rather schedule you once, well, than twice for the same reason.
Driveways, patios and walkways run $0.20 per square foot. A typical Greens at Ridgecrest two-car driveway is small enough that most homeowners bundle it with the front walk and the back patio on one visit. House washing is a separate soft-wash process at low pressure — we don't put high pressure on the vinyl siding common in this subdivision, and we don't put it on your window seals either. Monthly and Quarterly memberships are available with no contract if you want the pond-side concrete kept ahead of the algae instead of catching up on it once a year. We're fully insured and locally owned out of Meridian, founded in 2025 by Hunter Stevens and Ethan Seusy, with 115+ Google reviews at 4.9 stars.

Not by itself. Those streaks are iron from pressurized irrigation water sitting in the concrete pores, and pressure just cleans around them. We treat them with an oxalic application first, then wash. Most come out or drop to a faint shadow. On a slab that's been hit by the same head for a decade or more, expect big improvement rather than gone completely.
Yes. We soak and lift rather than blast, because dried droppings smear and grind into the surface under high pressure. Everything organic comes off. If the mess sat through a winter and the acid already etched the surface, you may be left with a lighter patch — that's texture in the concrete, not remaining dirt, and no amount of washing changes it.
Shared concrete is normally the HOA's responsibility and needs to be scheduled by the association, not by an individual homeowner. We're glad to bid it if your board wants a number. Anything on your own lot — driveway, front walk, back patio, side path to the gate — you can book directly with us.
On a tenth-acre lot, a driveway on its own is a small ticket at $0.20 per square foot. Most people here add the front walkway and the back patio to the same visit, which makes better use of the trip and gets the whole hardscape matching instead of one clean slab next to two dirty ones. Call and we'll price the combination.
We do, at reduced pressure and with a different technique. Full pressure on paver joints strips the sand out and you end up with shifting stones and weeds, and on stamped concrete it can lift a failing sealer unevenly. We'll tell you at the quote if your stamped patio looks like it needs resealing after cleaning, since washing exposes worn spots you couldn't see before.
Depends on your stain. If it's iron streaking from irrigation, wash after the pressurized system shuts down in October so it stays clean all winter. If it's algae and winter grime, spring is right. Patios backing the fairway pick up fresh residue after the course runs fertilizer, so we time those around the growing season rather than the first warm week.
