What Grows and Settles on Apple Valley Siding

Start with the build stage — Apple Valley is one of Meridian's original subdivisions, recorded 1973–1974 on one plat (ZIP 83646, about 80 acres). Meridian exteriors collect three separate things. On the north and east elevations, where sun never fully dries the wall, you get algae and mildew as a green-black film. Along the bottom three feet you get mud splash and irrigation overspray staining — the same canal mineral that marks the glass marks the siding, and on light-colored vinyl it reads as a permanent dingy band. Everywhere else you get the west-side farm ground along Black Cat and McDermott, which throws field dust east across these roofs every time it is disked or cut. Each needs different treatment, which is why a single pass with a pressure wand does a poor job on all three. On Apple Valley lots that water comes off the Boise Project Board of Control's pressurized line, which is why the problem shows up street-wide rather than house by house.

Soft Wash, Not Pressure — and Why That Matters Here

House washing is a chemical process, not a force one. We apply a surfactant-and-sodium-hypochlorite blend at low pressure, give it dwell time to kill the organic growth at the root, and rinse. High pressure on siding drives water up behind lap joints and into the wall assembly, strips the chalking layer off aging vinyl, and on the stucco and manufactured stone common in newer Meridian elevations it will take the finish off outright. Soft washing kills the algae rather than knocking the top off it, which is why it stays gone measurably longer. It is the single most common thing we get called about in Apple Valley.

Plants, Pets and the Irrigation Line

We pre-wet and post-rinse every bed on the wash path, tarp anything sensitive, and keep the mix off turf. Meridian yards are almost all on pressurized irrigation with the heads set close to the foundation, so we also make sure the system is not running mid-wash — a cycle firing partway through re-wets the wall and streaks it. If you know your zone schedule, tell us when we book and we will work around it. Apple Valley routes off McMillan, so getting here is not a special trip.

The Honest Limits

Soft washing removes organic growth and dirt. It will not fix oxidised vinyl, it will not remove efflorescence out of masonry, and it does not repaint anything. If your siding has chalked past the point of washing, we will say so before we start rather than after. Reflekt has been operating since April 2025, which is a shorter history than some of the companies you may be comparing us against. We would rather you knew that up front.

Doing It on One Visit

Bundling with window cleaning saves a trip charge and gets the sequence right. We will tell you honestly if you do not need the second service yet — a bundle you do not need is not a saving.
