The orange streaking on Southridge driveways is iron out of the irrigation water. The subdivision sits in south Meridian south of Overland, between Ten Mile and Linder in 83642, and it is a long build-out — the plats run 2011–2024 across 5 phases, so the housing stock spans a decade or more. Sprinkler water comes off the Boise Project Board of Control's system, not the city main. It runs about 84 acres.

Worth knowing first: Southridge is a long build-out — the plats run 2011–2024 across 5 phases, so the housing stock spans a decade or more (ZIP 83642, about 84 acres). Flatwork here carries a specific mix. Irrigation overspray leaves a white mineral bloom along driveway and walkway edges — the same canal mineral that rings the windows. Rust-orange streaking comes from the iron in that same water, and it is a different removal problem entirely from dirt. Add vehicle drip in the driveway apron, organic darkening where a downspout discharges, and valley dust, plus the winter inversion that holds particulate down at ground level for weeks at a time settling into the surface pores, and you have four stains that respond to four different approaches. Across roughly 84 acres it is remarkably consistent — Southridge is one job, not thirty different ones.
We run a rotary surface cleaner on flatwork rather than waving a zero-degree tip. A wand leaves striping — those parallel arcs you see on a badly washed driveway are wand marks etched into the cream layer, and they are permanent. The surface cleaner holds even pressure across the full width and produces a uniform result. Edges and tight spots get wanded deliberately at reduced pressure to blend rather than cut. On Southridge's newer builds the warranty paperwork usually still matters, so we work in a way that will not give anyone a reason to void it.
Pressure alone does not remove irrigation rust — it just blasts the surrounding concrete lighter and makes the stain more obvious. Rust needs an oxalic or similar acid treatment, applied, dwelled and neutralized. Mineral bloom needs an acidic masonry cleaner. Both are separate line items from a standard wash, and both work far better if the sprinkler head causing them gets turned. We will show you which head it is. Southridge routes off Overland, so getting here is not a special trip.
Pressure removes dirt. It does not remove deep oil that has soaked into the slab, it will not restore spalled or crumbling concrete, and we will not blast colour off stamped or sealed surfaces to make a before-and-after look better. Saying this plainly costs us the occasional booking and saves everybody the version where you find out on the day.
This pairs naturally with house washing, and doing both on one visit is cheaper than two separate trips — the setup and the drive are most of the fixed cost. It is also better work: there is an order these jobs should happen in, and doing them on separate days usually means doing one of them twice. Tell us what you want when you book and we will sequence it properly.

Not done properly. Damage comes from a narrow tip held too close, which etches the surface permanently. A rotary surface cleaner at appropriate pressure does not do that. Pavers and stamped concrete get lower pressure by default.
Usually, yes — but with chemistry rather than pressure. Iron staining from irrigation water needs an acid treatment and a neutralizing rinse. It is quoted separately from the wash because it is genuinely separate work.
$0.20 per square foot for standard flatwork. Rust and mineral treatments are quoted on top after we see them. Booking it alongside house washing saves a trip.
An outside spigot, yes. We bring our own equipment and power. If your spigot is on the irrigation system rather than city water, let us know — we need the treated line.
