Ruby Creek is the 45-lot Riverwood Homes phase completing Crimson Point, off Shayla Avenue, and all of its concrete is new. New concrete is not the easy case people assume, and the mistakes made on it are permanent.
The chalky white haze on a new Ruby Creek driveway is efflorescence: soluble salts migrating out of the slab as it cures and crystallising on the surface. It reads as a stain and it is normal curing behaviour. Blasting it at maximum pressure takes the bloom off along with some of the cement paste that holds the surface together, leaving a rougher, more porous slab that soils faster and blooms again. It wants the right treatment at moderate pressure, and repeat blooms in the first couple of years are expected.
Concrete continues gaining strength for a long time after pouring, and the surface paste on a slab under a year or two old is genuinely more vulnerable than it will be at five. An aggressive nozzle can etch visible wand marks or open the surface into a sandy texture that never fully recovers. On Ruby Creek we deliberately moderate pressure and let a surface cleaner and the correct chemistry do the work, which is the opposite of the instinct most people have about new concrete.
Alongside efflorescence, new Riverwood driveways typically carry mortar droppings, texture and paint overspray, sealant smears and fine cement slurry tracked around during the build, plus tyre marks from construction traffic. Those are separate problems from general soiling and some need spot treatment rather than a uniform pass. Getting them now is easier than later, because rubber and oil work progressively deeper into concrete pores.
Untreated Boise-Kuna canal water carries dissolved iron from the first irrigation cycle, so rust staining does not wait for the house to age. Where sprinkler overspray lands on new, light-coloured concrete and evaporates, the iron oxidises into the pores and the contrast on a pale new slab is stark. Adjusting the head that throws onto the concrete is the cheapest permanent fix, and we point out which one it is free of charge while we are on site.
Pressure washing at $0.20 per square foot is for the driveway, walks and patio at a pressure appropriate to the slab's age. Siding is house washing at $0.18 per square foot as a soft wash, and on a new build that distinction matters especially: caulk and sealant may not be fully cured and the wall assembly is still settling, so water driven behind the laps has nowhere to go. We quote the two separately.

No, lower. Concrete keeps gaining strength long after pouring, and the surface paste on a slab under a year or two old is more vulnerable than at five years. An aggressive nozzle can etch wand marks or open the surface into a sandy texture that never recovers.
Usually mortar droppings, texture and paint overspray, sealant smears, fine cement slurry tracked around the site, and tyre marks from construction traffic. Some need spot treatment rather than a uniform pass, and they are easier to remove now than later.
Because untreated canal water carries dissolved iron from the very first irrigation cycle. Where overspray lands on pale new concrete and evaporates, the iron oxidises into the pores, and the contrast on a light new slab is stark. Adjusting the head is the cheapest permanent fix.
Yes, free of charge while we are on site. It is the cheapest permanent fix available, and pointing it out costs us the repeat rust treatment, which is rather the point. A head throwing onto concrete will keep restaining it however often we clean.
Not at pressure. On a new build the caulk and sealant may not be fully cured and the wall assembly is still settling, so water driven behind the laps has nowhere to go. Siding is a soft wash at $0.18 per square foot, quoted as a separate line.
