Drive the alleys off Kootenai and the concrete tells you the year. Hand-troweled 1950s slabs, a gravel apron at the back garage, and a black cast under every maple where honeydew has fed sooty mold for decades. Morris Hill driveways are not dirty so much as stained, and that is a different job.
Every honeydew problem on this street has a second half. The aphids in the maple and linden canopy drip sugar all summer, and what lands on the driveway feeds sooty mold. That is the flat black-green cast under the drip line, darkest where the slab stays shaded past noon. People scrub it and it is back in three weeks, because scrubbing takes off the mold and leaves the food. It is also not a pressure problem. You can hold a tight tip on a black patch for a full minute and stripe the concrete without clearing it. What clears it is a soft-wash detergent given time to dwell, then a rotary surface cleaner at moderate pressure to rinse it off evenly. Same canopy that films your glass, different fix on concrete.
Morris Hill slabs were poured roughly between 1946 and 1962, hand-troweled, no fiber, no sealer, and most have never been coated since. Sixty Idaho winters of freeze-thaw leave the cream layer on top thin and in places already popped. Point a zero-degree tip at that and you do not clean it, you cut wand marks into it and expose aggregate in stripes that never blend back. We run a surface cleaner at reduced pressure and let water volume do the work, keeping the open wand off the field of the slab except on control joints and edges. Where the top surface is already delaminating we say so before we start, because washing a failing slab speeds it up. Old concrete also cleans up lighter and blotchier than new concrete. That is the material, not the wash.
Three Bench stains do not answer to pressure, and you should know that before you pay for it. Orange rings come from iron in sprinkler and irrigation water thrown across the slab; pressure just spreads them, an oxalic-based rust treatment pulls most of it, and it comes back every season unless the head gets re-aimed. Old motor oil soaked into a bare alley garage apron thirty or forty years ago is in the pores, not on top; a degreaser with real dwell time lifts the surface of it, and a shadow usually stays. White powder along edges and cracks is efflorescence, salt migrating up from under the slab, and it returns as the concrete dries no matter how clean the wash was. We call those out at the quote.
These lots are flat, fenced and fully grown in, and the garage usually sits at the back of the lot off an alley or a gravel drive. That layout changes how we wash. Gravel next to concrete means a careless wand angle throws rock into the lawn where a mower will find it, so we work that seam from the concrete side with the fan laid over. The junipers and yews planted against the foundation in the fifties are pressed right to the siding now, so beds get soaked before we start and rinsed after, because detergent sitting on dry roots burns them. And with three or four feet between house and chain-link on the side yard, dirty water has nowhere to run, so we push it out toward the drive instead of letting it stand against the foundation.
Pressure washing is $0.20 per square foot on driveways, patios and walkways, measured off the actual slab rather than guessed from the curb. A typical Morris Hill driveway plus the front walk lands somewhere in the 600 to 900 square foot range. Memberships run monthly or quarterly with no contract, which fits this neighborhood, since the sooty mold comes back on the same schedule the aphids do. Every visit carries our 7-Day Rain Guarantee. We hold same-day and next-day slots Monday through Saturday and we are on the Bench most weeks, so a Morris Hill address rarely waits long.

Usually not on its own. That black is sooty mold growing on aphid honeydew, and it is biological, so it needs a soft-wash detergent and dwell time to kill and release it. Raw pressure will lighten it while etching the concrete around it, which is how driveways end up striped. We apply, let it sit, then rinse with a surface cleaner at moderate pressure so the whole slab comes out one shade.
Most are fine at the right pressure. The ones we flag are slabs where the smooth top layer is already flaking or popping, usually along the street edge where de-icer and plow spray hit. On those, washing pulls more of the loose surface off, and you end up with a cleaner but rougher driveway. We do a test pass in a low-visibility corner first and show you the result before committing to the whole slab.
Most of the way, usually. Those are iron deposits from irrigation water, and they need a rust treatment rather than pressure. We can typically pull them back to a faint shadow, and on lighter concrete they disappear. The important part is the cause: if the head is still throwing across the concrete every morning, the ring returns within a season. Re-aim the nozzle or add a deflector and the cleaning holds a lot longer.
Fresh spills come out well. Decades-old oil in unsealed concrete has soaked deep into the pores, and a degreaser with dwell time plus hot agitation lifts the top layer of it, not all of it. Expect meaningful lightening rather than a clean slab. If it matters cosmetically, resurfacing or an opaque coating is the honest answer, not more washing. We tell you which one you are looking at before you book anything.
Pressure washing is $0.20 per square foot and we measure the actual concrete: driveway, front walk, back patio, alley apron if you want it. No guessing from the street. A typical Morris Hill driveway and front walk together run 600 to 900 square feet. Give us your address and roughly what you want cleaned at (208) 453-6760 and you get a real number, not a range that moves once we are in the driveway.
