The concrete in front of a Front Street storefront is not a suburban driveway. It is old, worn smooth by decades of foot traffic, and it collects three things at once: gum and spilled drink sugar off the sidewalk, oily soot drifting off Union Pacific's Nampa Yard, and tire drip from the diagonal parking.
Most of what darkens downtown concrete is not one stain, it is three stacked on each other. The first is traffic film: shoe rubber, dust and spilled soda worked into the surface right in the door swing and at the curb cut, which is why the walk is always darkest in a two-foot arc in front of the entry. The second is rail fallout. Downtown sits closer to Union Pacific's Nampa Yard than any other part of town, and the diesel soot that lands here is oily, so it grabs onto concrete instead of blowing off. The third is vehicle drip from the diagonal parking along Front Street and 1st Street South, which soaks into the apron at the curb. They come off in that order, and the drip is the one that fights back.
A lot of the concrete downtown was poured decades ago and has been walked on ever since. The cream on top, the fine layer that makes a slab look uniform, is long gone in the traffic lanes, and the aggregate sits close to the surface. Point a narrow tip at that and you carve wand stripes into it that never go away. We run a flat surface cleaner at moderate pressure so the water lands evenly, pre-treat with soap so the chemistry does the work, and give it dwell time instead of leaning on brute force. Painted brick, old mortar joints and stucco parapets get soft-washed at low pressure. A pressure washer will blow out soft lime mortar on a hundred-year-old building, and repointing costs far more than the wash ever did.
Worth knowing before you pay for it. Oil that has been soaking into porous old concrete for years is in the slab, not on it. A hot wash and a degreaser pull the top of it and lighten the spot, but a long-running drip stain where a delivery van parks will leave a shadow, and anyone promising otherwise is selling you a second visit. Rust does not come out with pressure at all, whether it is a sprinkler head throwing Nampa's hard well water across the walk or an old iron rail bleeding down the steps; that needs an oxalic rust treatment, priced separately. Concrete that is already spalling or popping aggregate gets worse under pressure, not better. If we see that on the walk-through we will say the wash is cosmetic and short-lived rather than take your money twice.
The front is what customers see; the back is what fails an inspection. Downtown's mixed-use buildings share alleys, and the pads behind the restaurant blocks carry cooking grease, dropped food and the black film that comes with both. Grease is a different job from traffic film. We dry-scrape and bag the solids first so we are not washing them into the storm drain, then hit the pad with a degreaser and hot rinse. Gum gets softened and lifted rather than blasted, because blasting a wad of gum on old concrete just spreads it into a gray halo. If your building has apartments upstairs, we work the alley early so the rinse and the noise are done before tenants are awake, and we keep water off any exterior stairwell that has to stay dry.
Driveways, patios, sidewalks and entry aprons are $0.20 per square foot. Measure the concrete you actually want washed, length times width, and that gets you close before we ever show up. Soft-washing painted brick or stucco is quoted separately since it is a lower-pressure, chemistry-first job. Timing matters more downtown than in a subdivision: we wash before you open or after you close so we are not running hoses through foot traffic and sidewalk seating. From roughly December through February we watch overnight lows and will move a job rather than leave water on concrete that is about to freeze, which is how joints get worse.

Yes, and we do it regularly. In most downtown blocks the upkeep of the walk in front of a building falls to the owner or the tenant even though the concrete sits in the right-of-way, so check your lease or with the city if you are unsure who is paying. Either way the job is the same on our end: we wash the frontage, the entry apron and the curb cut as one piece.
It will take out what is on the concrete, not what has stained into it. Traffic film, soot, gum and spilled drinks come off and the slab lightens noticeably. Deep oil, old paint drips and rust bleed are in the pores and will leave a shadow. On concrete that age you should expect it to look clean and evenly toned, not new. If it needs a rust treatment or a resurfacing conversation instead, we will tell you that on the walk-through.
It would if we used real pressure, so we do not. Soft lime mortar on a historic downtown building blows out under a pressure tip, and once a joint is open you are paying a mason instead of a washer. Brick, painted masonry and stucco get soft-washed: low pressure, the right cleaner, dwell time, gentle rinse. That is quoted separately from flatwork because it is a slower, more careful job.
Concrete is $0.20 per square foot, so a typical single-bay frontage of about twelve by twenty feet is a small job and a wide corner building with a wrap-around walk is more. Measure the length and width of the concrete you want done and multiply. Dumpster pads and grease areas are quoted on sight since degreasing takes more product and more time. Call (208) 453-6760 with your dimensions and we will price it over the phone.
That is normal for us downtown. We schedule before open or after close, and we avoid washing the walk right as foot traffic picks up around Indian Creek Plaza. Concrete is walkable as soon as the standing water is squeegeed off, usually within minutes, and fully dry within a couple of hours in summer. Tell us your hours and any event days on your block and we will build around them.
For a retail frontage, once or twice a year on the main walk and more often on a grease pad or a heavy entry. Do not let anyone talk you into quarterly concrete washing if your traffic is light, since the wash does not build up any protection and you are just paying for the same job sooner. If the door swing arc is visibly darker than the rest of the walk, it is time.
