Sterling Ranch driveways were poured between about 2015 and 2020, which means the concrete is still young and the irrigation is still untreated canal water. That combination shows up as orange fan-shaped sprinkler streaks across otherwise good-looking slabs off Deer Flat Road, and it needs a different approach than blasting it harder.
Sterling Ranch concrete went down in Kuna's 2015 to 2020 building wave, which makes it young by driveway standards. Young concrete still has its cream layer, the fine dense skin the finisher floated to the top, and that skin is what keeps the slab from drinking up oil, rust and dye. A narrow tip held six inches off a five-year-old broom finish will strip that skin, and you will see it for the life of the driveway as light wand stripes running the length of the pour. We run a surface cleaner at moderate pressure and let detergent and dwell time do the work instead of raw force. It takes longer on the clock. It is also the difference between a driveway that comes clean and one that comes clean once, then goes chalky the following summer.
Kuna runs on pressurized irrigation from the Boise-Kuna Irrigation District, untreated canal water turned on in April and shut off in October. That water carries iron and fine silt, and on lots this size the heads have to throw far enough that the last few feet of every arc land on the driveway, the front walk or the patio slab. Six months of that leaves orange fan-shaped streaks that trace the sprinkler pattern exactly. Here is the part worth knowing before you hire anyone: pressure alone does not remove iron staining. You can hit it at 4,000 PSI all afternoon and it stays orange, because the iron is down in the pore, not sitting on the surface. It takes an oxalic-based rust treatment applied and rinsed, and on stains that have sat through several seasons, some of it only lightens rather than disappears.
Sterling Ranch sits off E Deer Flat Road with open farm ground and pasture within sight on more than one side, and the wind that comes across it in late summer carries a fine dust that packs down into a broom finish and stays. That accounts for most of what makes concrete here read gray rather than dirty. It is not a stain, it is silt sitting in the texture, and it rinses out cleanly at normal pressure. The other pattern we see on these lots is the shaded side of the house. Covered patios and north-facing walkways that catch sprinkler overspray but never get direct sun grow a thin green-black film, and that is the slick spot by the back door every spring. Those get a soft-wash solution and a rinse, not high pressure, because the film has roots in the pores and blasting it just moves it around.
Sterling Ranch has shared hardscape, the pool deck and the walkways through the neighborhood park, and it takes a different beating than a driveway does. Foot traffic, sunscreen, spilled drinks and irrigation overspray from the common landscaping all land on the same slabs, and pool decks in particular hold a chalky film that homeowners often mistake for faded concrete. We quote common-area work separately from homeowner work, since the board is the party authorizing it and this kind of job usually wants an early morning start before the pool opens for the day. If you are on the HOA committee and want a real number, we measure the actual square footage rather than estimating off a plat map. Same $0.20 per square foot, and our insurance certificate goes on file before anyone starts a machine.
Pressure washing runs $0.20 per square foot on driveways, patios and walkways. Most Sterling Ranch homes have a two or three-car drive in the 700 to 1,000 square foot range, so a driveway by itself typically lands between $140 and $200, and adding the front walk and back patio is usually the better value since we are already set up. Rust treatment on iron staining is quoted separately because it depends on how far the staining has gone. We hold same-day and next-day slots through this side of Kuna and we are out on these streets often enough that scheduling is rarely the holdup.

Not by itself. Iron from Kuna's canal irrigation sits inside the concrete pore, so pressure cleans the dirt off and leaves the orange behind. Removing it takes an oxalic-based rust treatment applied to the stained area and rinsed. Fresh staining from one season usually clears well. Staining that has baked in for four or five summers often lightens substantially rather than vanishing, and we will tell you which one you have before we quote it.
That is almost always efflorescence, mineral salts migrating up through the slab and drying on the surface. It is common on concrete this age, especially where irrigation keeps the ground under it damp. We can wash it off, but be aware it can return, because the source is moisture moving through the slab, not anything sitting on top. Improving drainage or adjusting the sprinkler head that keeps that area wet does more long term than washing does.
Yes, with the pressure turned down and a fan tip kept moving. Stamped and integrally colored concrete usually has a sealer on it, and aggressive pressure will haze or peel that sealer in patches that look worse than the dirt did. We wash it at low pressure with detergent. If the sealer is already failing when we get there, we will point it out first so you are not blaming the wash for damage that was already underway.
It is $0.20 per square foot, so a 700 to 1,000 square foot driveway runs roughly $140 to $200 depending on the size of your pad. Front walkways and back patios are the same rate and are worth adding while the equipment is already staged, since the setup is the slow part. We measure rather than eyeball it, and you get the number before we start.
Late April through early October covers most of it. Spring is the popular slot because algae on the shaded walkways is at its worst right after the wet months and irrigation just came back on. Fall right after the canal water shuts off is arguably the smarter time, because you are washing off a full season of iron and silt with no new overspray landing on it for six months. Either works. Freezing weather does not.
Both, but with different methods. Flat concrete gets a surface cleaner. Siding and stucco get soft-washed, which means low pressure and the right solution, because high pressure can drive water behind trim and lap siding or crack stucco. Gutters and hardscape use standard soft-wash and pressure methods. Window glass is a separate service and we clean that with 100% pure deionized water instead.
