The orange streaking on Sunset West driveways is iron out of the irrigation water. It sits in Boise between Milwaukee and Glenwood, just south of Amity in 83709, and it is older than most of the city around it — recorded 1973–1975 across 5 phases. It covers about 309 acres, large enough that we route it as its own stop.

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. Across about 309 acres the pattern barely varies here.
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. That holds across 83709 generally, not just on this plat.
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. That is the honest reason we push timing as hard as we push method: doing this work at the right point in the Boise season is worth more than doing it more often at the wrong one. If you are on W Colt Dr or one of the streets off it, we are likely already working nearby.
Most Sunset West customers book this alongside house washing. Partly that is price, partly sequence — washing walls after cleaning glass puts dirty water back on clean panes, and hanging lights before clearing gutters means working around your own strands in January.
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. We are locally owned and fully insured, and we would rather point you to the right trade than take work we cannot finish well.

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.
