East End driveways are often the original pour, 1905 to 1935 concrete with ribbon strips and ninety years of freeze-thaw in the surface, sitting under a maple canopy a block off the Boise River Greenbelt. Shade, damp river air and irrigation iron make this hardscape a different job than a new slab in Meridian.
A lot of East End driveways are original to the house, which means 1905 to 1935 concrete: hand-poured, thin by modern standards, often two narrow ribbon strips with grass down the middle instead of a full slab. Ninety-plus years of freeze-thaw has carbonated the top surface and popped aggregate loose in patches, and much of it has been patched two or three times with newer mixes that sit at a different color. That matters before anyone pulls a trigger. On concrete that soft, a zero-degree tip or a wand held close will lift the paste and leave permanent wand stripes you can read from the sidewalk in raking light. We run a surface cleaner at moderate pressure so the water is spread evenly across every pass, and we test an out-of-the-way corner first to see what the slab will actually take.
North-facing walks and patios on the river side of the neighborhood stay damp far longer than anything up on the bench. Between the mature maple and elm canopy East End is known for and the humidity coming off the Boise River corridor, a shaded side walkway can go most of the summer without ever fully drying out. That grows a thin green-black algae film on the concrete, and on the shadiest stretches, real moss packed into the control joints and along the mortar line at the porch. Algae like that is a slip hazard well before it looks bad. We soft-wash it with a cleaning solution and dwell time rather than trying to blast it off, because pressure alone knocks the top layer loose and leaves the roots down in the pores, and it is back green in six weeks.
Two stains show up on almost every East End estimate, and neither behaves like dirt. The first is irrigation rust. Gravity-fed ditch water off the Boise River system carries iron, and a sprinkler head throwing across a driveway apron all summer paints an orange fan on it. The second is tannin ghosting from leaf drop and cottonwood, dark blotches that soaked in while wet leaves sat through winter. Here is the honest part: neither one comes out with pressure alone. Rust is a chemical stain sitting in the pore structure, not a layer on top, and you can strip that concrete to sand and the orange is still there. It needs an oxalic-based rust treatment. Tannin usually lifts most of the way with the right cleaner and dwell time, but on old porous concrete a faint shadow can stay. We tell you which of those you have before we quote, not after.
East End has a lot of masonry that predates the war: brick porch steps, brick and sandstone foundation courses, original clay pavers on side walks, and mortar joints mixed with lime rather than modern portland. Soft old brick and lime mortar are the one thing on these properties we will not put pressure on. A wand blows the mortar joints out and pulls the fired face off the brick, and once that face is gone the brick wicks water and spalls a little more every winter after. We wash historic masonry with low pressure and a cleaner, more rinse than force. Same for painted wood porch decks and old stair treads, which fuzz and splinter under a tight fan. If a walkway is already loose or a joint is failing, we show you before we start instead of washing it apart.
Pressure washing is $0.20 per square foot on driveways, patios and walkways, so a typical East End driveway plus the front walk is a straightforward number to quote off a measurement. Rust treatment and heavy moss work get called out separately, since those take chemistry and dwell time rather than more passes. Gutters and house washing are priced on their own. On timing: late June, once cottonwood fluff has finished, catches the algae while it is still thin, and a pass after the fall leaf drop keeps tannin from soaking in over winter.

It can, in the wrong hands. Concrete that old has a carbonated, softened top surface, and a narrow tip held close will cut into it and leave striping that never goes away. We use a surface cleaner at moderate pressure so force is spread over the whole pass, and we test a hidden corner first. If a slab is already spalling badly, we will tell you that washing cleans it but does not restore it.
Because it is iron, not dirt. Ditch and irrigation water in this part of Boise carries iron, and a sprinkler head hitting the driveway all summer drives it down into the pores of the concrete. Pressure removes what is sitting on the surface, and the stain is below that. It takes an oxalic-based rust treatment to pull the color out. We flag rust at the estimate so nobody is surprised by what plain washing leaves behind.
We can slow it down a lot. Shaded, damp walks near the Greenbelt grow algae because they never fully dry, and blasting it off leaves the roots in the concrete so it returns fast. We use a cleaning solution with dwell time to kill it rather than just knock it loose, which buys most homeowners a full season instead of six weeks. Trimming back whatever is holding the shade helps more than any washing does.
Yes, but not with pressure. Pre-war brick with lime mortar is soft, and a pressure wand will chew the mortar joints out and strip the hard fired face off the brick, which starts a spalling problem every winter after. We wash historic masonry with low pressure and a cleaner. If joints are already crumbling, we will point that out first so you can get them repointed before we put any water on them.
Two windows work best here. Late June, after cottonwood fluff off the river is done, gets the summer algae while it is thin and easy. Then a pass after the fall leaf drop, before the wet weather sets in, keeps leaf tannin from soaking into porous concrete over winter. If you only do one, take the fall one. Winter tannin staining is the harder of the two to remove later.
Driveways, patios and walkways are $0.20 per square foot, measured off the actual surface we are cleaning. Ribbon-strip driveways get measured as the strips, not the grass between them, which usually makes them cheaper than people expect. Rust treatment and heavy moss removal are quoted separately because they need chemistry and dwell time. Call (208) 453-6760 and we will give you a real number rather than a range.
