Most driveways in Star are under ten years old, poured during the fastest growth spurt of any Treasure Valley city, so what's on them isn't decades of grime — it's builder overspray, curing dust, and canal-irrigation silt from sprinkler heads planted a few feet off the garage.
Because so much of Star was built in the last five to ten years, a lot of the driveways we quote have never actually been dirty in the traditional sense — they came out of the pour with stucco splatter from the trim crew, dried mortar dust from stone-veneer wainscot work, paint overspray from the garage door, and a fine gray haze of drywall dust tracked out of the house during finish-out. That residue bonds harder to a broom finish than ordinary dirt does, especially once a summer or two of sun bakes it in. It's common in newer sections of Norterra, Trapper Ridge and Cranefield, where homes closed out only a year or two ago and the driveway has never been properly cleaned since the builder walked off the lot.
Nearly every subdivision in Star runs untreated pressurized irrigation off Boise River canals and laterals, live roughly mid-April through mid-October, and because lots here are small and new, sprinkler heads sit close to the foundation and often fire straight at the driveway apron, garage door and stone wainscot. The silt and dissolved minerals in that water dry into a gritty tan-to-orange film on concrete and a matching stain creeping up the bottom couple feet of siding and stone. A hose won't touch it — it needs pressure behind a flat-surface cleaner on the concrete and a lower-pressure rinse on anything vertical. We finish with pure deionized water, no soap, so there's no surfactant residue left for the next irrigation cycle to grab onto.
Star's west side backs onto Canyon County farmground, the county with more working farms than anywhere else in Idaho, and northwest wind carries that dust into Star before it reaches Eagle or Meridian. Spring disking and planting run March through May, hay gets cut repeatedly May through September, and corn silage chopping plus grain harvest August through October lay down the heaviest load of the year — a fine tan silt that settles into broom-finish concrete and paver joints and won't rinse out on its own. Add June cottonwood and Russian olive fluff off the Boise River on the south side of town, and driveways near the Star River Walk or Floating Feather Road pick up a mat of organic debris that traps moisture and starts growing algae in shaded corners.
If your driveway was poured in the last 28 to 30 days, wait — fresh concrete is still curing, and pressure washing it too early can open the surface and make it more likely to absorb the next stain instead of shedding it. Efflorescence, the chalky white bloom common on new slabs and stucco right after a wet spring, is salt migrating out through moisture; pressure washing lifts it temporarily but it returns until whatever's feeding the moisture changes. And if your driveway or a stretch of it along Floating Feather Road or the river-bottom acreages is gravel or decomposed granite rather than poured concrete, there's no hard surface to wash — we clean concrete, pavers and stone, not loose rock.
Flatwork is $0.20 per square foot for driveways, patios and walkways, measured on site so the number in your hand matches what actually gets washed, not a satellite-photo guess. Given how fast this town's concrete reloads with irrigation film and ag dust, the two cleanest windows are late April through early May, right after canal turn-on but before summer heat bakes spots on, and mid-to-late October, after harvest dust and leaf drop settle but before winter inversions arrive. We run Monday through Saturday, 7am to 7pm, closed Sunday, with same-day and next-day slots most weeks.

Flatwork is $0.20 per square foot for driveways, patios and walkways. A standard two-car driveway runs close to 500-600 square feet, so roughly $100-120, with a front walk added on top. Star lots and driveways run newer and often slightly larger than the valley average, so we measure on site rather than estimating from a photo, and you see the total before we start.

Usually, yes. Paint overspray, dried mortar dust and stucco splatter from finish-out work bond to a broom finish harder than ordinary dirt, especially after a summer of sun. A flat-surface cleaner at full pressure lifts most of it. Paint overspray that's had years to cure can leave a faint shadow even after cleaning — we'll tell you honestly on site if that's likely before we start.
Not right away. Concrete needs about 28 to 30 days to cure before it can safely take pressure washing. Washing it too early can open the surface and make it more absorbent to future stains rather than less. If your driveway was poured within the last month, we'll ask the pour date and schedule around it rather than risk the surface.
That's almost always irrigation, not age. Star runs untreated canal and lateral water through pressurized sprinklers, and because lots are small, heads often sit close to the house and fire straight at it. The silt and minerals in that water dry into a tan-to-orange film on the lowest few feet of siding, stone and concrete. Pressure washing removes it; redirecting the sprinkler head keeps it from coming back.
No — there's no hard surface there for us to clean, and blasting loose rock just moves it around. That's common on older river-bottom acreage along Floating Feather Road. We wash poured concrete, pavers and natural stone. If a gravel driveway leads to a concrete apron, paver walkway or stone patio, we're glad to do those.
Late April to early May, right after canal irrigation turns on but before summer heat locks the spotting in, and mid-to-late October, after harvest dust and leaf drop but before winter inversions settle over the valley. Midsummer works too, but a driveway washed in June is usually re-filming within a week or two once daily sprinklers resume.
