Boise concrete takes a beating no other valley city's does: decomposed granite grit washing down out of Hulls Gulch, aphid honeydew dripping off North End maples, and untreated Boise City Canal water spotting everything it touches. We clean driveways, patios and walkways with flat-surface equipment and a deionized final rinse.
Four dirt sources stack up inside a five-mile radius here. Off the Boise Front, nightly downslope drainage out of Hulls Gulch, Crane Creek and the Military Reserve carries pale decomposed-granite grit onto driveways in the Highlands, Boise Heights and Warm Springs Mesa. It is sharp and fine, and it grinds down into the pores instead of sitting on top. Under the North End and East End canopy, silver maple and linden aphids mist honeydew onto walkways all summer; that sugar film feeds black sooty mold, and October's leaf load leaves tannin stains that look like spilled tea. On the Bench, jet soot off Boise Airport and Gowen Field settles on top of Fairview and Vista traffic film. December through February, inversion soot and ACHD road brine glaze the whole apron.
Boise is laced with live gravity irrigation. The Boise City Canal runs from Warm Springs Avenue across the old city out to Collister and Hill Road. The New York and Ridenbaugh cut the south rim and feed pressurized systems through Southeast Boise and Columbia Village. That water is untreated: silty, algae-carrying, mineral-heavy. One impact head aimed a foot off leaves a gritty tan band across a patio plus hard white spotting, and in the newer subdivisions it arrives with enough throw to hit a second story. Municipal water isn't much gentler. Hardness commonly runs 10 to 13 grains per gallon, and the well-fed West Bench and Southwest Boise zones usually test harder than downtown. Both leave mineral crust a garden hose only re-wets. We finish with 100% pure deionized water, no soap, so nothing is left to dry into a spot.
A flat-surface cleaner does most of the work. It's an enclosed rotary head that overlaps its own passes, so you don't get zebra striping down the middle of a driveway. Pressure gets matched to the slab, not the other way around. A 1990s West Valley driveway or a Barber Valley broom finish takes full pressure. A 1920s North End sidewalk already showing exposed aggregate, or the porch steps on a Craftsman bungalow, gets stepped down and worked slower. We stay off Table Rock sandstone caps and retaining walls at pressure entirely, because that stone is soft and blasting it costs you the face. Same rule for lime mortar on Harrison Boulevard-era brick and for polymeric sand in newer paver joints, which blows out at the wrong tip and angle.
Three things get mistaken for dirt, and none of them are. Efflorescence, the white bloom on a patio or foundation wall, is salt migrating out with moisture from below. It rinses off and comes right back within weeks. Fix the drainage or the sprinkler hitting that wall first. Spalling and flaking on a Bench driveway is freeze-thaw damage in concrete that has already lost its surface; pressure takes more of it off, it does not clean it. And plain gray is often just a sixty-year-old slab that carbonated and lost its color, with nothing on it at all. Rust from ditch-water iron or a bleeding sprinkler head won't move with pressure either; that needs a separate oxalic treatment. If your driveway is one of these, we'll say so and you keep your money.
Flatwork is $0.20 per square foot for driveways, patios and walkways, measured, not guessed from the curb. You get the number before we unroll a hose. We're out Monday through Saturday, 7am to 7pm, closed Sunday, with same-day and next-day slots most weeks. Reflekt is locally owned and fully insured, started in 2025 by Hunter Stevens and Ethan Seusy, and we hold a 4.9-star average across 115+ Google reviews.

Flatwork is $0.20 per square foot, so a standard two-car driveway around 600 square feet runs about $120, and a front walk adds whatever it measures. Patios price the same way. We measure on site rather than quoting off a satellite photo, and you have the number before any work starts. Call (208) 453-6760 for a same-day or next-day slot.
Two windows work best. Late April into May, after the mid-April irrigation turn-on has pushed the season's dirtiest first water through every head and the elm samaras and maple keys have finished dropping. Or late October into November, once the North End and Bench canopy has dumped its leaf load and before tannin sets over winter. Summer is fine, but at 95 degrees and ten percent humidity everything flash-dries, so we work smaller sections.
That's algae and sooty mold, and under a mature North End or East End canopy it's completely normal. Shade keeps the surface damp, and honeydew dripping off the maples and lindens feeds it. It's also the most slippery thing on your property in January, which is the real reason to deal with it. Pressure removes it, but if the branches and the sprinkler stay the same, expect it back in a season or two.
The tan silt band comes off. The hard white mineral spotting usually does too, though heavy build-up on a patio hit by the same head for several summers can take a second pass. Rust-orange staining from iron in ditch water won't move with pressure alone and needs a separate oxalic treatment. The lasting fix is aiming the head; two degrees of adjustment saves the slab and the glass above it.
On concrete, yes, with pressure matched to the slab. A 1920s North End or Warm Springs sidewalk gets far less than a 2005 Harris Ranch patio. On other materials, not always. We won't put pressure on Table Rock sandstone steps or retaining walls, soft historic brick, or the lime mortar common on Harrison Boulevard-era houses, because it takes the face off the material and there's no putting it back.
Yes, and it's the natural pairing, because flatwork throws splash onto glass and light fiber cement. Window cleaning is our main work. We rinse with 100% pure deionized water and no soap, which dries without spots and leaves the RainShield finish. Siding is quoted from a walk-through instead of the flat square-foot rate, since a painted 1915 bungalow and a Barber Valley fiber cement wall aren't the same job.
