Sundance concrete went in with the houses, mostly 2003 to 2007 off Ustick and Meridian Road, and almost none of it was ever sealed. Twenty summers of pressurized irrigation and twenty winters of freeze-thaw later, the driveways here stain in a pattern you can read from the street.
Sundance went in as a CBH tract off the northeast corner of Ustick and Meridian Road, poured mostly between 2003 and 2007. That matters for concrete work. New-construction driveways out on Meridian's west edge still carry curing haze and mortar splatter and take a light touch. Sundance concrete has the opposite problem: two decades of weather and almost none of it ever sealed. The broom finish has worn smooth in the wheel tracks and stayed rough along the edges, so grime sits deeper where you drive and rinses off where you don't. Wash that with a wand and you get a clean stripe down the middle with gray bands on either side. We run a surface cleaner at a fixed height across the whole slab so it comes out one color, then hand-detail the borders and the expansion joints.
The rust-colored fan along your driveway edge isn't dirt. Sundance runs on pressurized irrigation, untreated canal water off the Boise River system, and that water carries iron and fine silt. Every head that throws across the concrete paints an arc, and after fifteen or twenty summers those arcs are stained into the surface, not sitting on top of it. Here's the honest part: pressure alone does not take iron out of concrete. You can hit it at 4,000 PSI and etch the slab before the color moves. It takes an oxalic or rust-specific treatment, dwell time, and a rinse, and on old porous concrete you should expect a big improvement rather than a disappearance. Anybody promising to blast it clean is going to hand you a lighter stain and a rougher driveway.
The trees planted with these houses are grown in now, and that changed what lands on the flatwork. Leaf litter sitting wet on a patio through fall leaches tannin, which is the brown blotch under where the pile sat and the dark speckling under a maple or ash. On these compact CBH lots the side-yard walk between houses barely sees sun from November through March, and that strip grows the green-black algae film that gets slick after a rain. The good news is that organic staining is the kind that actually comes off. We treat the growth rather than just knocking it down with water, so it doesn't return in six weeks, and we keep the wand angle off mortar joints and paver sand where a patio isn't poured concrete.
Concrete this age has taken twenty winters of freeze-thaw plus whatever ice melt got thrown at it. Where the top surface is already flaking, the popcorn texture you can pick loose with a fingernail, that's spalling, and pressure will take more of it with it. We drop pressure over those areas and tell you what we're seeing instead of washing a driveway into needing replacement. Same with control joints that have opened up and with the street apron, which catches the worst of the plow grit. Flat runs get the surface cleaner so there's no zebra striping, edges get hand-wanded, and we direct water away from the garage threshold and the weep screed at the base of the siding. Almost nothing here has a sealer left, so there's none to strip.
Driveways, patios, and walkways run $0.20 a square foot. A typical Sundance driveway is a two-car apron plus the run to the garage, and the front walk and back patio are usually worth adding while we're already set up, since the trip is the fixed cost. Memberships are Monthly or Quarterly with no contract, but concrete honestly doesn't need quarterly. Once a year in spring, after irrigation kicks on and before you start using the patio, covers most houses on these streets. The 7-Day Rain Guarantee applies, though rain matters more on glass than on flatwork. Same-day and next-day slots are usually open.

Partly. Those arcs are iron from the pressurized irrigation water, and it soaks into the concrete rather than sitting on it. Pressure by itself will not lift iron, no matter how high you crank it. We use a rust-specific treatment with dwell time and then rinse. On twenty-year-old porous concrete that usually means a big fade, not a clean slate. We'll tell you what we think it'll look like before we start.
It can be, with the pressure backed off over those spots. Flaking is spalling from freeze-thaw and de-icing salt, and the surface layer is already letting go. Aggressive washing removes more of it and makes the patch bigger. We wash around and over it gently, get the rest of the slab even, and point out anything that looks like it's headed toward repair rather than cleaning.
We price flatwork at $0.20 a square foot, so it comes down to how much concrete you have. A standard two-car driveway with the approach, plus the front walk, is the common Sundance job. Give us the rough dimensions on the phone and we'll quote it on the spot. Adding the back patio at the same visit is cheaper than a separate trip later.
Usually it fades a lot and doesn't fully vanish. Oil and transmission fluid wick down into unsealed concrete, and pressure only reaches what's near the surface. We degrease it, let it sit, and wash it out, which pulls the dark halo way back. A years-old drip under a regular parking spot will likely leave a shadow. We'd rather say that up front than have you expect new-looking concrete.
Yes, and the side-yard strip is often the one that needs it most. On these lots it sits in shade most of the winter and grows the black-green algae film that gets genuinely slippery. It's the same $0.20 a square foot, and since it's a small area it barely moves the total. We treat the growth so it stays gone longer instead of just rinsing it off.
Spring is the sweet spot here, once the irrigation is running and before patio season, so the winter grit and last fall's tannin come off together. Late fall after leaf drop is the second-best window. We keep same-day and next-day slots open most weeks, so a Sundance address can usually get on the schedule fast. Call (208) 453-6760.
