The orange streaking on Shadow Valley Estates driveways is iron out of the irrigation water. It sits in Boise north of Beacon Light, between Maple Grove and Milwaukee in 83714, and it is new ground: recorded 2020–2025 in two phases, with homes still going up. At roughly 118 acres it is one of the larger communities in the city — which is what the quote is built from.

Flatwork here carries a specific mix. Irrigation overspray leaves a white mineral bloom along driveway and walkway edges. Rust-orange streaking comes from the iron in that same water and is a different removal problem entirely. Add vehicle drip in the apron, organic darkening where a downspout discharges, and decomposed granite off the foothills, plus the winter inversion that traps particulate at ground level for weeks at a time settling into the surface pores, and you have four stains that respond to four different approaches. We see it most consistently on the homes along N High Valley Way.
We run a rotary surface cleaner on flatwork rather than waving a zero-degree tip. A wand leaves striping — those parallel arcs on a badly washed driveway are wand marks etched into the cream layer, and they are permanent. Rust needs an oxalic treatment, dwelled and neutralised, not more pressure. Pavers lose joint sand if you hit them hard, and stamped or coloured concrete has its colour in a thin surface layer that strips, so both get lower pressure by default. Being this close to Beacon Light means the road-facing elevation is always the one that needs the most attention.
Boise glass carries something the rest of the valley does not: foothills grit. Decomposed granite off the slope is sharp and fine, it travels on the afternoon downslope wind, and in winter the valley inversion holds everything else down at ground level with it. On a Shadow Valley Estates property that shows up as a shorter useful interval than the same work would hold somewhere else in the valley, which is worth knowing before you decide how often to book. At about 118 acres, Shadow Valley Estates is small enough that neighbours booking together is genuinely cheaper for everyone.
Pressure removes dirt. It does not remove deep oil soaked into the slab, it will not restore spalled 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.
Bundling with house washing saves a trip charge and gets the sequence right. We will tell you honestly if you do not need the second service yet — a bundle you do not need is not a saving.

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.

$0.20/sq ft. The final number depends on the property, and there is no contract and no membership requirement. Booking it alongside another service on the same visit is the cheapest way to do it.
Usually — but with chemistry rather than pressure. Iron staining needs an acid treatment and a neutralising rinse, quoted separately from the wash.
An outside spigot, yes. We bring our own equipment and power. If your spigot runs off the irrigation system rather than treated water, tell us.
