Downtown concrete is not driveway concrete. What we wash off 8th Street, the Basque Block and Grove Plaza is sidewalk, restaurant patio and alley slab, surfaces that take gum, kitchen grease, street tree drop and winter de-icer instead of the tire marks and sprinkler rust we chase out on the Bench.
Most of what we pressure wash downtown is not a driveway. Parking here is structures and metered curb, so the horizontal concrete that actually needs cleaning is the public sidewalk in front of your door, the seating patio spilling onto 8th Street, the entry apron under the awning, and the alley slab behind the building where the dumpster and the grease barrel sit. Those four surfaces get dirty in completely different ways, and we do not run them at the same pressure or the same chemical. A retail frontage is mostly foot traffic, gum and tree drop. A restaurant patio is food, drink sugar and grease. The alley is almost always the worst surface on the property and the one nobody thinks to have cleaned until it starts to smell in July.
Downtown Boise plants street trees in wells along Main, Idaho, Capitol and 8th, and those trees are the single biggest source of sidewalk staining we see. Ornamental pear and linden drop fruit and sticky sap that foot traffic grinds into the surface until it reads as a dark blotch instead of a spot. Add birds roosting in the same trees and you get droppings that etch if they sit through a hot week. Then there is gum, genuinely the most common thing on a busy retail sidewalk, and winter de-icing salt, which leaves a chalky white haze along entries and curb cuts by March. Each of those wants a different approach. One pass of cold high pressure lifts the loose dirt and leaves all four of them sitting right there.
A lot of downtown's ground floor is brick from the early 1900s with soft lime mortar, and a fair amount of the hardscape around the Basque Block and the older blocks is brick paver or scored masonry rather than poured slab. High pressure on any of it is a mistake. Put a 3,000 PSI tip on hundred-year-old mortar and you blow the joints out; put it on the brick itself and you strip the fired face, leaving a rough chalky surface that soils faster than it did before. Those surfaces get a soft-wash approach instead: proper cleaning solution, real dwell time, low pressure, thorough rinse. It takes longer and it looks better six months later. If a bid on old brick is unusually fast and cheap, someone is planning to blast it.
These come up constantly and we would rather say it before you pay for it. Old oil that has been soaking into a slab under a delivery vehicle for years is in the concrete, not on it. We can pull the surface layer and the shadow stays, and more pressure does not change that. Rust from a metal planter, a bike rack foot or an irrigation line is a chemical problem, not a pressure problem, and needs an oxalic treatment rather than a stronger tip. And concrete that has been spalling from years of de-icing salt is not dirty, it is losing its surface, so washing it hard exposes more aggregate and looks worse than when we started. On that last one we will usually tell you to leave it alone.
Pressure washing runs $0.20 per square foot for driveways, patios and walkways, so a storefront frontage plus entry apron is a small number and a full patio plus alley is a bigger one. Give us the footprint and we will quote it straight. Downtown storm drains run toward the Boise River, so we control runoff instead of pushing grease and gum water into the nearest inlet, which matters more here than anywhere else in the valley. We schedule around your hours: early before doors open, after close, or a slow midweek block. Same-day and next-day slots open most weeks. Memberships run monthly or quarterly with no contract, plus a 7-Day Rain Guarantee.

Gum comes off, but not with a wand and cold water alone, which smears it into a gray ring. It needs heat and direct contact at close range, worked piece by piece before the general wash. On a busy retail frontage that is often the slowest part of the job, so tell us roughly how many pieces are out front when you call and we will price it honestly instead of surprising you on site.
It can, in the wrong hands. Early 1900s brick with soft lime mortar does not survive a high-pressure tip: the joints wash out and the fired face comes off the brick, leaving a surface that soils faster afterward. We soft-wash that masonry instead, with cleaning solution, dwell time, low pressure and a full rinse. Tell us the building age when you call so we bring the right setup.
Yes, and it is usually the surface that needs it most. Alley slab behind a restaurant picks up kitchen grease, dumpster leakage and grit, and grease does not respond to pressure by itself. It needs a degreaser with real dwell time and a hot rinse, or you are just moving it around. It is also where runoff control matters most, since that is a lot of organic material sitting near a storm inlet.
We control it rather than chasing it toward the nearest inlet. Downtown storm drains discharge toward the Boise River without treatment, so grease and gum water get contained, filtered or diverted to an appropriate drain depending on the job. It is more work than blasting everything at the curb, and it is a fair question to ask any contractor bidding hardscape downtown.
A restaurant patio or a busy retail frontage on 8th Street holds up best at two to four times a year. A quieter side-street entry can go once annually. Watch the entry apron under the awning as your tell: shaded concrete that never sees direct sun holds moisture and greens up first, so if that patch is darkening, the rest of the frontage is due too.
Usually, yes. We work in sections and time it around your hours, before opening, after close, or a slow midweek morning. Sidewalk and entry work can be staged so your door stays usable throughout. A full patio wash is easier before service starts, since the surface needs time to dry before furniture goes back down. Tell us your hours when you call and we will build the visit around them.
