Concrete in Delaware Park carries four stains that need four approaches. It sits in Caldwell off Hwy 20/26 in 83605, and it is a staged build-out recorded 2001–2021 across 9 phases, which puts the oldest homes here well ahead of the newest. At roughly 103 acres and about 406 lots 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 Canyon County farm dust off the dairy, seed-crop and row-crop ground that still surrounds the city on three sides, plus the harvest traffic that comes with it settling into the surface pores, and you have four stains that respond to four different approaches. Across roughly 406 lots it is remarkably consistent — Delaware Park is one job, not a hundred different ones.
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. On Delaware Park's newer builds the warranty paperwork usually still matters, so we work in a way that will not give anyone a reason to void it.
Two things drive this in Caldwell: untreated surface water through the city's own irrigation district, and Canyon County farm dust off the dairy, seed-crop and row-crop ground that still surrounds the city on three sides, plus the harvest traffic that comes with it. Separately each is manageable. Together they bond, and that is the condition we are actually treating on a Delaware Park job. At about 103 acres, Delaware Park 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.
