Most Sunnyslope houses are custom country builds — stucco or board-and-batten on acreage, with big south and west walls facing open vineyard rows and no shade for a quarter mile. That exposure is the whole story here: the sun side chalks, the north side greens up, and the sprinkler line stains the bottom three feet.
Drive the bench and the same three or four siding types come up over and over. Stucco — usually a synthetic finish over foam or wire lath — is the most common on custom builds from the 2000s on, and its texture holds dirt the way a sponge holds water. Board-and-batten and painted cedar show up on the older farmhouses and on the newer barn-style builds. Hardie plank covers most of the last decade's houses. Straight vinyl is the exception out here rather than the rule, and when we find it it's usually on a manufactured home or a shop building. Each one takes a different amount of pressure and a different dwell time, and the wrong call on stucco chews the finish coat off in a way repainting never fully hides.
Sprinkler line is the first. Acreage lawns run big impact heads off pressurized irrigation or a well, and that water carries iron and hard minerals. After a few seasons it leaves an orange-brown band across the bottom two to four feet of every wall a head can reach, heaviest on the side facing the lawn. Second is north-side algae. North and northeast walls stay shaded and damp until late morning out here, and they green up with a thin black-green film that reads as dirt but is alive. Third is sun-side chalking, where south and west walls take unshaded afternoon light off open ground for years until the painted or vinyl surface oxidizes into a powder that comes off on your hand. Three problems on one house, and only two of them are dirt.
This is the part most quotes skip. Algae and general dust come off clean — that's exactly what a soft wash is for, and those walls look new. Sprinkler iron staining usually lightens a lot but doesn't always disappear; if it's been baking into stucco for eight or ten years, expect real improvement, not erasure, and the actual fix is redirecting the head. Chalking is the honest one. Chalk isn't dirt, it's the paint or vinyl surface itself breaking down, so we can rinse the loose layer off and the wall will look better, but the color under it is already faded and it will chalk again. That wall needs paint, not washing, and we'd rather say so on the walk-around than after we've cashed the check. Pressure fixes none of the three — more pressure only damages siding.
Soft wash means low pressure and a detergent that does the work while it dwells, then a thorough rinse. Nothing gets a pressure wand aimed at it. Before anything hits the wall we soak the landscaping, and on the bench that often means grapevines, fruit trees, or a raised bed within a few feet of the foundation, then we rinse it all again when we're done. We ask where your water comes from, because plenty of these properties run off a well and we'd rather agree on a spigot up front than find out mid-job. Long gravel drives mean a longer hose run from the truck, gates and dogs mean a call before we pull in, and detached shops and barns get quoted separately if you want them included.
House washing is $0.18 per square foot, soft-wash, and it's safe on stucco, Hardie, board-and-batten, cedar, and vinyl alike — the price doesn't change with siding type, the method does. No contract on anything. Monthly and Quarterly memberships are there if you'd rather have the house, windows, and gutters handled on a rhythm than remember to call, and every visit carries our 7-Day Rain Guarantee. We run same-day and next-day slots out on the bench the same as we do in town.

It will lighten them, often a lot, but I won't promise they vanish. That band is iron and mineral out of your irrigation or well water, and on textured stucco it soaks into the finish rather than sitting on top. Newer staining usually comes back close to clean. Ten years of it will improve and still ghost. Redirecting the head that's hitting the wall is what actually stops it.
Pressure washing does wreck it, which is why we don't do that on siding. Soft wash runs low pressure — closer to a garden hose than a pressure washer — and lets the detergent do the work while it sits. That's what lifts dirt out of stucco texture without stripping the finish coat. Same approach on Hardie, cedar, board-and-batten, and vinyl, with the dwell time adjusted for each.
Usually it's algae, sometimes with a little mildew mixed in. North and northeast walls out here stay shaded and hold morning damp well past sunrise, and that's all algae needs. It comes off completely with a soft wash. If it's coming back within a season, look at what's holding moisture against that wall — shrubs planted tight to the foundation, or a sprinkler zone overspraying the north side.
We can wash the loose chalk off and the wall will look noticeably better for a while, but that's a paint or siding problem, not a dirt problem. Chalking is the surface itself oxidizing from years of unshaded south and west sun, and it keeps chalking after the wash. If you're planning to paint anyway, wash first — it's the right prep. If you're not, know what you're buying.
Most out here do fine on once a year, which is less often than people expect. Vineyard and orchard dust dulls the walls but rinses off easily. What drives a second visit is algae on the shaded side or a sprinkler head that's been painting the same wall all summer. If the house just looks dusty and there's no green and no orange band, it can usually wait.
No, but tell us where everything is when you book. We saturate plants and beds with plain water before any detergent goes up, keep the mix off them while it dwells, and rinse everything down again afterward. Vines trained on a wall or trellis close to the siding we'll work around by hand. If a bed matters to you, point it out on the walk-around and we'll plan the rinse around it.
