The flatwork around Ridgecrest Golf Club takes a beating the rest of Nampa doesn't. Pressurized irrigation off the canal throws iron and silt onto driveway aprons and side walkways, and the mature trees on these lots hold enough shade that the film turns black instead of drying off.
Most Ridgecrest driveways we get called out to have the same mark, and it isn't grime. The pressurized irrigation in these subdivisions runs untreated canal water, and that water carries iron. A head aimed even slightly off target throws it across the concrete in a fan, the sun bakes it in, and by August you have a rust-orange arc on the apron that reads as permanent. Pressure alone will not take it out. You can run a machine over that spot all afternoon and only brighten the concrete around it, which makes the rust look worse than before you started. It needs an oxalic-based rust treatment with real dwell time, then a rinse. We say that up front, because a wash that skips the chemistry looks like a failed job.
Fairway sprinklers and your own PI zones both throw silt along with the minerals, and it lands on whatever flatwork sits closest — the apron, the back patio, the path down the side yard. Silt by itself just reads dull and grey. What makes it black is the algae that grows in it on the north and east faces of the house, where the big trees on these lots hold shade most of the day. That black film is also the part that goes slick in the first real fall rain, which is why we start on the walkway to the front door and the back patio steps before we touch the big square footage out front. We pull it with a surface cleaner in overlapping passes so the concrete dries even instead of striped.
Flatwork out here is not all the same pour. Standard broom-finish driveway takes full pressure through a surface cleaner. Stamped and colored patio concrete does not — the color sits in the top layer, and a wand held too close will lighten it in streaks you cannot put back. Paver patios and walkways get low pressure and a wider fan, because blasting the polymeric sand out of the joints buys you a wobbly patio and weeds next spring. Sealed concrete gets tested in a corner first. If your slab is already spalling — flaking, pop-outs along the apron where the plow salt and the freeze-thaw got at it — washing will not repair that, and too much pressure widens it. We'll clean it and tell you honestly what you're left with.
Two cases where we tell people to wait. First, white chalky bloom on newer concrete is usually efflorescence — salts working their way out of the slab as it cures. On concrete under about a year old that comes back after every wash, so the money is better spent after its first full winter. Second, if the driveway looks dingy but rinses clean under a garden hose in a test patch, you have dust, not embedded soil, and you do not need us yet. What genuinely warrants a wash: black shaded film that stays after rain, an algae edge that feels slick underfoot, or the rust arcs. If you send a photo we'll tell you which one you've got before anyone gets scheduled.
Driveways, patios and walkways run $0.20 per square foot, measured off what we actually clean. A typical three-car Ridgecrest apron near 900 square feet lands around $180, and adding the back patio and the side path in the same visit is cheaper than bringing us back twice. Rust treatment is quoted separately because it depends on how long the stain has been baking. We soft-wash siding rather than pressure it, and we do not run pressure on windows — the glass side of the house is 100% deionized water only. Same-day and next-day slots are usually open, and every job carries our 7-Day Rain Guarantee.

Because that is exactly what it is. The pressurized irrigation here runs untreated canal water carrying iron, and a head aimed a little off throws it onto the concrete in a fan pattern that bakes in over the summer. Pressure alone will not lift iron out of concrete. It takes an oxalic-based rust treatment with dwell time, then a rinse. The long-term fix is turning that head a few degrees off the slab.
We charge $0.20 per square foot on driveways, patios and walkways, measured off the actual area cleaned. A three-car apron around 900 square feet comes to roughly $180. Adding the back patio and the side walkway on the same visit costs less than scheduling two trips. Rust treatment is quoted on top, since it depends on how deep the stain has set. You get the number before we start.
It can, in the wrong hands. Stamped and colored concrete holds its color in the top layer, so a wand held too close leaves lightened streaks that cannot be undone. Pavers lose their joint sand under direct high pressure, which means shifting and weeds later. We drop pressure and widen the fan on both, re-sand joints when needed, and test sealed surfaces in an out-of-sight corner before committing to the whole patio.
Usually, but not with pressure by itself. Oil that has soaked in needs a degreaser worked in and given time before we hit it, and old drips often lighten rather than vanish completely. Hot-tire marks from a car parked in the same spot come out better than oil does. We will tell you what we expect to get before we start rather than leaving you to guess at a shadow afterward.
Once a year covers most homes here, and late spring is the right window — after the irrigation has been running long enough to show you where the overspray lands, but before the algae builds through summer. Homes with heavy tree shade on the north side of the walkways sometimes want the walkways and steps done again in early fall, since that is the slick surface people actually walk on.
Yes. Common sidewalks, mailbox pads and shared entry walks price the same way, at $0.20 per square foot over the total area. We just need whoever is authorized for the association — a board member or the property manager — to approve the scope, since we will not bill a homeowner for concrete they do not own. We can walk and measure it and send one quote covering the whole run.
