Crimson Point's driveways went in between 2000 and 2008, which makes them some of the oldest residential concrete in Kuna. Two decades of Boise-Kuna canal water off the sprinklers, tannin drip from grown-in trees, and freeze-thaw on unsealed broom finish. Most of it cleans up. A little of it won't.
Kuna's first tract wave ran 2000 to 2008, and Crimson Point was part of it. That means the driveways, walkways, and back patios here are pushing twenty years or more on a standard broom finish, and most were never sealed after the builder poured them. Unsealed concrete is porous. Every season it takes on whatever the sprinklers throw at it, and in Crimson Point that is untreated Boise-Kuna Irrigation District water off the New York Canal, carrying suspended silt and dissolved iron. The silt packs down into the broom grooves and grays the whole slab. The iron does something worse. Add the field dust that blows in off the farmland south and west of the subdivision and you end up with concrete that reads uniformly dirty rather than spotted. A surface cleaner and hot water pulls most of that back out in one pass.
If your driveway has orange-brown arcs that match where a sprinkler head sweeps, that is not dirt and it is not coming off with pressure. It is iron out of the irrigation water, oxidized and bonded into the top layer of the slab. We have watched people spend an hour on those arcs with a turbo nozzle and finish with a clean, etched driveway that still has orange arcs on it. Rust needs a chemical, not force: an oxalic-acid-based remover, applied, given dwell time, then rinsed. On stains a season or two old that usually takes them out completely. On twenty-year-old arcs soaked deep into an unsealed slab, expect them to lighten several shades rather than disappear. We will tell you which one you have before we start, not after you have paid.
The landscaping that went in with these houses has had twenty years to fill in. Good for the yard, hard on any concrete it shades. North-side walkways and the strip of patio under a mature maple or ash stay damp long after the rest of the slab has dried, and damp porous concrete grows a black-green organic film people mistake for permanent staining. Leaf litter left sitting through a wet spell adds tannin on top of that, a yellow-brown blotch shaped like whatever fell there. Both come off, but not the same way. Organic growth wants a low-pressure soft wash with a real cleaner and dwell time, because blasting it only knocks the surface layer off and it regrows within weeks. Tannin needs dwell time too. Pressure by itself just drives it further into the pores.
Concrete poured in 2000 has been through more than twenty Kuna freeze-thaw cycles, and along driveway edges and downspout splash zones you will usually find spalling, pitting, or pop-outs where the surface paste has already let go. Those areas will not take full pressure. Hitting them with a narrow tip strips more paste, widens the pit, and leaves wand marks, the zebra striping you can still see from the street years later. We run a flat surface cleaner at controlled pressure across the field of the slab so every pass overlaps evenly, then hand-detail edges, expansion joints, and the garage apron. If you sit on an HOA board or handle a shared walkway, mailbox pad, or common entry, the same rate applies and we can quote the whole footprint in one measure instead of lot by lot.
Driveways, patios, and walkways run $0.20 per square foot. A typical Crimson Point three-car driveway lands somewhere around 700 to 900 square feet, so figure roughly $140 to $180, and we measure rather than eyeball it. Rust treatment and heavy organic work get quoted on top once we have seen the slab. Hardscape here does not need quarterly service. Most Crimson Point driveways look right on one wash a year, best done in late spring once the irrigation has run long enough to show you where the overspray is truly landing. Our Monthly and Quarterly memberships are built around glass, not concrete, and neither one has a contract. Same-day and next-day slots open up regularly since we route through Kuna anyway.

Almost always iron out of the irrigation water. Crimson Point runs on pressurized Boise-Kuna Irrigation District water off the New York Canal, and that water carries dissolved iron that oxidizes once it dries on concrete. The curve is the sprinkler's sweep. Pressure will not remove it. It takes an oxalic-acid-based rust remover with dwell time, and on twenty-year-old stains expect real lightening rather than a total disappearance.
Not when the pressure is matched to the slab. Concrete poured between 2000 and 2008 has taken a lot of freeze-thaw, and edges, splash zones, and pop-out areas have already lost surface paste. We run a flat surface cleaner across the field at controlled pressure and hand-detail the edges. What wrecks old concrete is a narrow turbo tip held in one spot, which strips paste and leaves permanent wand striping.
Once a year suits most homes here, and late spring is the best window because the irrigation has been running long enough to reveal where the overspray really lands. If your walkways sit under grown-in trees and build organic film, every eight or nine months makes sense. Concrete that has simply darkened to an even gray is not dirty, it is cured. That does not need washing at all.
Sometimes fully, sometimes partly. Fresh oil on unsealed concrete sits near the surface and lifts with a degreaser, dwell time, and hot water. Oil that soaked into a porous twenty-year-old slab several years ago has migrated down into the pores, and no amount of pressure reaches that. We can lighten it substantially. If someone promises total removal on an old deep stain in unsealed concrete, be skeptical.
Yes. Shared walkways, mailbox pads, entry aprons, and common-area concrete price at the same $0.20 per square foot as a private driveway. Quoting the whole footprint in one measure is simpler and faster than handling it lot by lot. If your HOA or a group of neighbors on the same street wants it all done in one pass, call and we will measure the full run.
It helps. Leaving them off the morning of and the day after lets the concrete dry evenly, so you see the finished result without fresh mineral overspray already on it. It is not required. Our 7-Day Rain Guarantee is aimed mainly at glass; on concrete, rain right after a wash does not undo anything, since the slab has already been rinsed clean.
