Concrete in Gramercy carries four stains that need four approaches. The subdivision sits in southeast Meridian between Locust Grove and Eagle Road, just south of Overland in 83642, and it is platted 2007–2009 in two phases and now fully built. About 67 acres, compact enough that we can usually do several homes in one visit. The Boise Project Board of Control supplies the pressurized irrigation on these lots.

The thing that shapes this job most is that Gramercy is platted 2007–2009 in two phases and now fully built (ZIP 83642, about 67 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 Eagle Road traffic film — brake dust and diesel particulate carried off the busiest arterial in Ada County settling into the surface pores, and you have four stains that respond to four different approaches. On Gramercy lots that water comes off the Boise Project Board of Control's pressurized line, which is why the problem shows up street-wide rather than house by house.
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. Gramercy routes off Overland, so getting here is not a special trip.
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. Gramercy is inside our standard 83642 service area — no travel surcharge.
Gramercy is on our regular Meridian route, not a special trip. We already work E Blue Horizon Dr, E Gala Ct, S Luxury Ln and S Wells Ave inside the subdivision. It routes off Overland, 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.
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. 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 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.
