Silver Falls is 63 lots off Placerville Street with a wider spread of construction dates than any single-builder subdivision in Kuna. For house washing that age range matters, because siding does something over twenty years that it does not do in five.
Vinyl siding exposed to twenty summers of Idaho sun loses surface plasticiser and begins to oxidise, which shows as a faded, slightly powdery surface. Run a hand down it and you get chalk on your palm. That changes the wash completely: an aggressive approach on chalking vinyl strips pigment and leaves visibly lighter patches, and even a correct wash will remove some loose chalk and reveal an uneven colour that was hidden under uniform grime. We check for chalking first and tell you what the result will realistically look like.
This is the honest conversation that older siding needs. Washing a chalked wall makes it clean, and clean will look better but not new, and in places it may look patchier than it did under a layer of dirt. That is oxidation showing rather than a poor wash, and telling you beforehand is the difference between a satisfied customer and a disappointed one. On the newer Silver Falls streets none of this applies, which is why we walk the house rather than quoting from the address.
The older streets here have landscaping that has had time to grow in, which most of Kuna does not, so those walls carry things newer subdivisions do not: aphid honeydew dripping from overhanging canopy, which is a sticky sugar film that dust then sticks to, plus algae and mildew on shaded north elevations. Neither rinses off. Honeydew in particular has to be dissolved rather than displaced, and it is a common reason a wall feels tacky rather than merely dirty.
Older vinyl is more brittle, its fasteners have had two decades of thermal cycling, and its caulk lines have opened. High pressure on that assembly drives water behind laps that no longer seal properly and into a wall with older housewrap, and it can crack brittle panels outright. Soft washing at $0.18 per square foot is the correct method and considerably more so on old siding than new. Pressure washing at $0.20 per square foot belongs on the concrete.
Parcels run from 0.156 acres up to 0.38, more than two and a half times, inside just 63 lots. House washing prices on actual wall area at $0.18 per square foot, so a large-lot home with a wide roofline carries considerably more wall than a compact neighbour even when the houses look similar from the street. We measure on site, and on the older homes that visit includes checking the siding condition before we commit to a method.

Yes, carefully. Chalking is oxidation from twenty summers of sun, and an aggressive approach strips pigment and leaves lighter patches. Even a correct wash removes loose chalk and can reveal uneven colour that uniform grime was hiding. We check for it first and tell you what to expect.
Clean, but not new, and in places possibly patchier than it looked under the dirt. That is oxidation showing rather than a poor wash. We would rather tell you that beforehand than have you see it afterwards and feel short-changed.
Aphid honeydew, most likely, from overhanging canopy on the older Silver Falls streets. It is a sticky sugar film excreted by aphids feeding in the leaves above, and airborne dust then sticks to it. It has to be dissolved rather than displaced, so rinsing does not shift it.
The opposite. Older vinyl is more brittle, its fasteners have had two decades of thermal cycling and its caulk lines have opened, so high pressure drives water behind laps that no longer seal and can crack panels outright. Soft washing matters more on old siding, not less.
Lot and roofline width. Silver Falls parcels run 0.156 to 0.38 acres inside 63 lots, and washing prices on actual wall area at $0.18 per square foot, so a wide-roofline home on a large lot carries considerably more wall than a compact neighbour.
No, which is why we walk the house rather than quoting from the subdivision. Newer Silver Falls homes have no oxidation, no mature canopy and no honeydew, so they are a straightforward wash. The age range within these 63 lots is the widest in Kuna.
