Half the driveways in West End were poured when the cottages went up, and half are infill slabs less than five years old. Those two do not take the same pressure. The old alley ribbon drives spall if you hit them hard, and the new pours are still blooming efflorescence.
Most West End blocks have both, sometimes side by side. The original cottage drives are narrow, occasionally still a two-strip ribbon with grass down the middle, and after eighty-odd Idaho freeze-thaw winters the top paste is gone in patches with aggregate showing through. Concrete like that is already shedding its surface. Run a narrow tip at full pressure across it and you cut lines into it that stay visible far longer than the dirt you took off. We drop pressure on those and run a flat surface cleaner so the water lands evenly instead of in a concentrated stripe. A spalled section will come out clean and still look mottled afterward, because that is the concrete you are seeing, not dirt we left behind. The newer infill drives next door handle a normal wash without any of that fuss.
A lot of the older West End houses park off the rear alley instead of a street driveway, and plenty of those alleys are gravel or chip seal at best. Every time you pull in you drag alley grit onto the apron, and by August that fine dust has worked into the surface and holds a gray cast a garden hose will not touch. The strip right in front of a detached garage door is usually the dirtiest square footage on the property: alley dust, oil drips, and roof runoff if the garage has no gutter. We blow and sweep the loose material off before any water goes down, because pressure washing gravel dust mostly relocates it into the yard and then back onto the wet slab. Then we clean toward the alley, not toward the house.
West End caught Boise's infill wave harder than most established neighborhoods, so there is a lot of concrete here under five years old, and new concrete brings its own mess. The chalky white film is efflorescence, salt migrating out of the slab as it cures and dries. Pressure knocks the surface bloom off and the slab looks great, but it does not stop the process, and it can return two or three more times across the first couple of years. Small orange freckles usually trace back to rebar tie wire sitting close to the surface, and those bleed again too. Mortar and stucco splatter left over from the build is a permanent win and worth removing before it hardens further. If your slab was poured inside the last twelve months, say so when you book. It gets a lighter wash than cured concrete.
Three stains show up on West End hardscape that no amount of pressure fixes. Irrigation rust, the orange fan where a sprinkler head throws iron-heavy water across concrete, is a chemical stain down in the pores and needs an oxalic treatment rather than more psi. Motor oil that sat on old porous concrete through a summer has soaked past where water reaches; degreaser and a second pass lighten it, and the honest expectation is lighter, not gone. Tannin bleed under the mature trees on the older blocks, that reddish ring where a leaf pile sat, usually lifts but can ghost on rough concrete. The one that does come off completely is the black-green organic growth on shaded north-side walks, common this close to the river and the Greenbelt. That is biological, and a soft wash takes it back to bare concrete.
Driveways, patios and walkways run $0.20 per square foot, so you can measure length times width and do the math before you ever call. We need a working outside spigot and access to the surface, which on the alley-garage blocks means gate or alley access rather than the front curb. Move the cars and the pots and we handle the rest. Monthly and Quarterly memberships are available with no contract if you would rather keep the hardscape up than rescue it once a year, and every visit carries our 7-Day Rain Guarantee. Same-day and next-day slots are often open. Reflekt is locally owned and fully insured, founded in 2025 by Hunter Stevens and Ethan Seusy, with 115+ Google reviews at 4.9 stars. Call (208) 453-6760.

Usually yes, at lower pressure. The first thing we check is whether the surface paste is already spalling or the aggregate is exposed. If it is, we drop pressure and run a flat surface cleaner so the water hits evenly instead of in a concentrated stripe. It will come out clean, but a slab that has lost surface in patches still looks mottled afterward. That is the concrete showing, not dirt we skipped.
Not with pressure alone. That orange is iron out of irrigation water bonded into the concrete pores, so blasting it just cleans the dirt around the stain and makes it stand out more. It takes an oxalic rust treatment and a thorough rinse. Mention it when you book so we bring it, and the real fix afterward is adjusting the head so it stops throwing water onto the concrete.
You can, as long as you know what you are buying. White haze on new concrete is efflorescence, salts working their way out while the slab cures. Washing removes the current bloom and it looks sharp, then it often returns once or twice more over the next year or two. Mortar splatter and construction grime from the build are permanent wins worth removing now. The efflorescence is maintenance until the slab settles.
Downhill to the storm drain, which in West End is a short trip to the Boise River. On plain concrete we clean with water and pressure and nothing goes down the gutter but dirty water. When a section needs degreaser or a rust treatment we contain and neutralize that spot rather than let it run. We also sweep grit and leaves off before starting so we are not pushing debris into the drain.
Driveways, patios and walkways are $0.20 per square foot. A narrow cottage driveway around 10 by 40 feet is 400 square feet, so $80 on that area, and the front walk adds to it. The wider infill drives run more simply because there is more slab. Measure length times width on everything you want cleaned, then call (208) 453-6760 and we will confirm on site.
No, we work alley access on these blocks regularly. It helps to tell us ahead of time so the truck stages in the right place, and to leave the gate unlocked. We also need an outside spigot we can reach. On gravel alleys we sweep the loose material off the apron first, otherwise the wash carries it right back onto the wet slab and it dries as a gray film.
