Lexington Hills went up in Eagle's mid-2000s-to-2010s wave, which means vinyl lap siding with stone or stucco accent on the front elevation. That combination stains in three predictable places: the bottom three feet from irrigation, the north and east walls from algae, and the south and west walls from sun.
Nearly every Lexington Hills elevation we've worked is vinyl lap siding on the sides and back, with a stone veneer wainscot or a stucco accent panel across the front to break up the street view. A few of the later-built lots got fiber cement on the front instead. Vinyl lap is not a sealed surface. Every course laps over the one below it with an open seam, and a pressure wand aimed upward will drive water straight up behind that lap and into the housewrap, where it has no fast way out. We don't do that. Soft-wash means low pressure and a cleaning solution that does the work chemically, then a rinse. It's the same approach on stucco accent, which will lose its texture in patches under a pressure tip and cannot be spot-repaired invisibly.
Lexington Hills runs on Eagle's untreated pressurized irrigation off the canal system, not treated culinary water. That water carries silt and dissolved mineral, and rotary and impact heads throw it against the lower two or three courses of siding several times a week from April through October. What builds up there is two different problems stacked on each other: a soil-and-organic film that washes off easily, and a hard mineral crust that has bonded to the vinyl. The soft wash takes the film off completely. The mineral scale usually lightens a great deal and sometimes clears, but on siding that's had ten-plus seasons of overspray with no washing, expect improvement rather than perfection. We'll tell you which one you're looking at before we quote, not after.
If one wall of your house looks dingy green or streaked black and the others don't, it's almost always the north side, sometimes the east. Those walls hold morning dew and stay shaded, and that's where algae and its darker cousin actually colonize the siding. It's a living organism, not deposited dirt, which is why homeowners who rent a pressure washer and blast it off are annoyed to see it return within a season. Pressure removes the visible layer and leaves the root structure in the vinyl's texture. A soft-wash solution kills it, so the wall stays clean far longer. Homes in Lexington Hills with mature trees or a close side-yard fence line on the north tend to be the worst cases on the street.
Here's the honest one. Twenty years of Idaho sun on the south and west elevations oxidizes the pigment in vinyl siding, and it leaves a fine powder on the surface. Run your palm down a sunny wall — if it comes back with a chalky white film, that's oxidation, not dirt. Washing removes the loose chalk and evens out the color, and the wall will look noticeably better and match the shaded sides again. But faded vinyl is faded, and no wash restores original color. If somebody quotes you a house wash and promises your south wall will look new, they're selling you something. Badly chalked siding wants paint or replacement; a wash buys you a cleaner, more uniform version of what you've got.
House washing runs $0.18 per square foot, soft-wash, safe on vinyl, stucco, fiber cement, brick and stone. Most Lexington Hills homes are standard two-story tract footprints, so the whole exterior is a single-visit job with no lift or specialty rig involved, and we usually have same-day or next-day slots for the neighborhood. If you'd rather not think about it, memberships run monthly or quarterly with no contract, and the 7-Day Rain Guarantee covers you if weather turns right after we finish. We're locally owned, fully insured, founded in 2025 by Hunter Stevens and Ethan Seusy, and carry 115+ Google reviews at 4.9 stars. Call (208) 453-6760 and tell us which walls are bothering you — that usually tells us the whole story.

It can, and we don't use it on vinyl. Lap siding has an open seam at every course, and an upward-angled pressure tip pushes water behind the laps into the housewrap and wall cavity, where it dries slowly. We soft-wash instead: low pressure, a cleaning solution that does the work, then a rinse. Same approach on stucco accent panels, which lose texture permanently under a pressure tip.
Because that wall stays shaded and holds dew longer, so algae actually grows there. The sunny walls dry out too fast to support it. It's a living organism rather than dirt, which is why blasting it off with pressure brings it back within a season — the visible layer goes, the root structure stays in the vinyl texture. A soft-wash solution kills it, so it stays gone much longer.
Partly to fully, depending on how long it's been building. Eagle's irrigation water is untreated and mineral-heavy, and overspray leaves both a soil film and a hard mineral scale. The film comes off completely. The scale usually lightens significantly and sometimes clears, but after a decade of overspray with no washing it may not vanish entirely. We'll look at it and tell you honestly which you have before quoting.
It will improve it, but it won't restore the color. Chalking is the vinyl's pigment oxidizing from years of sun — rub the wall and check your palm for white powder. Washing removes the loose chalk and evens the wall back out with the shaded sides, which is a real visual difference. But faded is faded. Heavily chalked siding is a paint or replacement conversation, not a washing one.
Once a year suits most homes here, ideally late spring after the pollen drops or early fall. If your north wall is heavily shaded by mature trees or a close fence line, or your irrigation heads hit the siding directly, you may want the shaded wall and lower courses done more often than the full house. Memberships are monthly or quarterly with no contract if you'd rather not track it.
We can, and we sequence it deliberately. House wash first, glass afterward — the soft-wash solution and rinse water will spot glass if it's cleaned first. Window work is done separately with 100% pure deionized water and no soap, which is what leaves the spot-free finish. Booking both in one visit is common in Lexington Hills and saves you a second trip on the schedule.
