Southern Ridge is a current Hubble Homes Craftsman build off Nampa's south side, so the siding here is vinyl lap with stucco and stone accents, all of it under five years old. That changes the job completely. Nothing on these walls is weathered yet — what we're fighting is the sprinkler line and the shaded walls.
Walk a Southern Ridge house and the dirt sorts itself into bands you can see from the sidewalk. The bottom two to four feet — where pressurized irrigation hits the wall — carries a tan-to-rust mineral film that is not dirt at all. The north and east elevations, especially anything shaded by the neighboring house on these tight new lots, carry a thin green-black algae film that wipes off wet and comes back. The south and west walls just carry dust and pollen sitting on top of vinyl that the sun is slowly dulling. Those three things do not respond to the same chemistry or the same pressure, and a crew that treats the whole house as one wash will leave you with a clean upper story and a stained skirt. We mix and dwell differently by elevation for exactly that reason.
New landscaping means new pressurized-irrigation zones, and PI water in this part of Nampa carries silt and iron that city water does not. Sprinkler contractors aim heads for turf coverage, not for keeping overspray off the house, so on a lot this new the heads are usually still throwing onto the bottom of the siding several times a week. What that leaves is a hard mineral band, and here is the honest part: soap does not remove mineral. Soft-washing lifts the organic film and the dirt riding on it, but a set-in iron stain needs a separate acid-based mineral treatment, and even that will not always take a heavily stained stucco skirt back to new. The permanent fix is adjusting or lowering the heads that are hitting the wall. We will point out which ones they are while we work.
The lots in Southern Ridge sit close together and the trees are still saplings, so the shade on these houses comes from the neighboring structure rather than a canopy. That gives you a north or east wall that stays damp well into the morning most of the year, which is all algae needs. It shows up as a gray-green haze that people usually read as "the siding is just older on that side." It is not older, it is biological, and it is why pressure alone fails on it. Blasting algae off vinyl knocks the visible growth down while leaving the roots in the surface texture, so it returns in weeks and you have driven water behind the laps for nothing. Soft-washing at low pressure with proper dwell time kills it at the root, which is the difference between a wash that lasts a season and one that lasts a year or more.
South and west vinyl in the Treasure Valley eventually chalks — the UV breaks down the surface and leaves a fine powder that comes off on your hand. On a Southern Ridge house that is years away. If you rub the sun-side wall and your palm comes back with a light gray dust rather than the pigment of the siding, that is dust film, and it washes off. If it comes back the color of your siding, that is oxidation, and no wash restores it; that is a refinishing conversation, not a cleaning one. Same goes for timing overall: if the only thing you can see is a sprinkler band on an otherwise clean house, we would rather quote you the skirt than sell you a full wrap you do not need yet. Most houses at this age need the full house every other year and the shaded walls annually.
House washing is $0.18 per square foot as a soft-wash process, safe on vinyl, stucco, hardie and the stone accents on these Craftsman elevations — we never put a pressure wand on stucco or on siding this new. Mineral treatment for sprinkler staining is quoted separately once we see how deep it has set. Pair it with your window cleaning and we will rinse the glass with 100% pure deionized water afterward so the wash does not leave spots.

Usually not the whole house yet. On a build this new the wear is concentrated: a mineral band at the sprinkler line and an algae film on whatever wall the neighboring house shades. Those two are worth handling early. The sun-facing walls at this age are typically just dust. If that is all you have, we will tell you and quote the sections that actually need it.
Pressurized irrigation overspray. PI water here carries silt and iron, and heads aimed for turf coverage often hit the bottom two to four feet of the wall several times a week. It is a mineral deposit, not dirt, so it does not come off with soap. It needs a separate acid-based treatment, and it will come back unless those heads get adjusted.
It can, which is why we do not use it on either. Pressure forces water behind vinyl laps where it sits in the wall cavity, and on stucco it erodes the finish coat and can open hairline cracks. House washing here is a soft-wash: low pressure, with the cleaning solution and dwell time doing the work. That is what the $0.18 per square foot covers.
Because it is algae, not dirt, and most washes only remove what you can see. On these close-set lots the north and east walls stay damp into late morning, so anything left in the surface texture regrows fast. A soft-wash with proper dwell time kills it at the root instead of knocking the top off, which is what makes the difference in how long it stays clean.
Yes, and it is worth knowing that active lots nearby put stucco dust and framing grit in the air that will resettle. If your street still has building going on, mention it when you book. In some cases we will suggest waiting until the adjacent lots finish rather than washing twice, and we will be straight with you about which situation you are in.
For most homes at this age, the full exterior every other year and the shaded north or east elevation annually, since that is where algae recurs. Houses with sprinkler heads hitting the wall need the lower band addressed more often until the heads are adjusted. A Quarterly or Monthly membership covers it on a set schedule with no contract.
