Flatwork in Blackrock shows irrigation bloom, iron staining and settled valley dust. The subdivision sits in far south Meridian between Locust Grove and Eagle Road south of Amity in 83642, and it is a turn-of-the-2000s subdivision, recorded 2006–2007 on one plat. It covers about 224 acres, enough that there is real variety in elevation and glass package, and that scale is part of the quote. Sprinkler water comes off the Boise Project Board of Control's system, not the city main.

The thing that shapes this job most is that Blackrock is a turn-of-the-2000s subdivision, recorded 2006–2007 on one plat (ZIP 83642, about 224 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 the working farm ground still south of Amity, which puts field dust on this glass through every spring disking and every fall silage run settling into the surface pores, and you have four stains that respond to four different approaches. Across roughly 224 acres it is remarkably consistent — Blackrock is one job, not thirty different ones.
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. If you are on E Taconic Dr or one of the streets off it, we are likely already working nearby.
Not everything gets the same pressure. Pavers lose joint sand if you hit them hard, and a paver patio washed aggressively will need re-sanding and may shift. Stamped and colored concrete has its color in a thin surface layer that strips. Sealed surfaces cloud. We drop pressure for all of it and tell you upfront when the honest answer is that a surface should be cleaned gently and resealed rather than blasted clean. Blackrock is inside our standard 83642 service area — no travel surcharge.
Blackrock is on our regular Meridian route, not a special trip. We already work E Lawton Dr, S Bentwaters Way, E Taconic Dr and E Renwick Ct inside the subdivision. It routes off Amity, which is how we keep travel out of the price. We schedule by area rather than by first-come, which keeps drive time down and means we can hold prices where they are. It also means there is usually a crew working within a few streets of you most weeks of the season.
Most Blackrock customers book this alongside house washing. Partly that is price — one visit rather than two — and partly it is 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. We handle the order so you do not have to think about it.

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.
