Eagle gets spring from two directions at once. Cottonwood comes up off the Boise River corridor along the south edge of town, and fine decomposed-granite silt washes down out of the foothills with every spring storm. Homes built for foothill views have the most glass pointed straight at the second one.
North of Floating Feather and Beacon Light, in Spring Valley, Dry Creek Ranch, and the foothills estates toward Willow Creek, the ground climbs into sagebrush and decomposed granite. That grit is pale, sharp, and mica-flecked, and afternoon northwest wind pushes it down onto long gravel drives and straight at the large north and east elevations that make a foothill home worth buying. Big uninterrupted view panes show a haze that smaller windows hide in their framing, which is why homeowners up here often notice spring dirt earlier than neighbors a few miles south in the valley floor subdivisions.
Properties toward Eagle Island State Park and Mace River Ranch take the same cottonwood release Garden City and Boise get off the same river gallery, usually running from mid-May into June. The rule is the same everywhere along that corridor: let the drop finish before cleaning, or plan on doing it twice, since fresh fluff mats into screens and keeps shedding onto the glass behind them. Homes further north, out of the corridor and up toward the foothills, can generally clean earlier without that problem.
Eagle lots run larger than the valley average, and nearly every subdivision waters off untreated canal and river water moved through the New Dry Creek Ditch Company and the Farmers Union Canal. More acreage means more zones, longer run times, and more chances a head is throwing at the house unnoticed. Eagle's tap water already runs close to 14 grains hard, among the hardest in the valley, so canal overspray on top of that is what actually etches glass by midsummer. Spring start-up is the one time of year the whole system gets watched, and it's worth walking every zone before summer bakes the mineral on.
Spring storms move that same decomposed-granite grit down off the foothills and onto the lower portions of siding, stucco, and fencing, not just the glass above. It rinses off readily with a soft-wash at $0.18 per square foot, and getting it before summer heat sets it into stucco texture and stone-veneer joints is easier than after. Older Eagle Hills homes under mature canopy from the 1960s through the 1980s deal with less of this grit than the newer foothills tracts, since the trees break the wind before it reaches the wall.
Windows start at $199 by pane count, screens are +$50, gutters from $199, pressure washing $0.20 a square foot, and soft-wash house washing $0.18 — the same rate whether the siding is stucco, EIFS, cultured stone, or vinyl. Every visit finishes with 100% pure deionized water and no soap, so nothing is left behind to spot on Eagle's hard water. Memberships are Monthly or Quarterly with no contract; Quarterly saves $100 per cleaning and includes a free annual screen clean, backed by a 7-Day Rain Guarantee.

After the cottonwood release finishes if you're near the river corridor, generally by mid-to-late June. Further north toward the foothills, once the spring storms settle and stop pushing granite grit down onto the glass.
Large view panes north of Floating Feather and Beacon Light catch wind-driven decomposed-granite silt off the bench, and big uninterrupted glass shows haze that smaller framed windows visually hide.
Window pricing follows pane count rather than lot size, starting at $199. Gutters start at $199 and scale with the roofline, and house washing is $0.18 per square foot regardless of siding type.
Yes, and on acreage it matters more. Eagle's canal-fed irrigation and roughly 14-grain tap water mean more zones and more opportunity for a misaimed head to spray the house all summer unnoticed.
Fall is better for preventing algae. Spring is better for clearing winter runoff silt and the season's first granite grit off the lower walls before summer sun bakes it into the stucco.
Yes, including horse and vineyard parcels out toward Willow Creek and Pearl Road. Well water or city water doesn't change the wash — the granitic grit packed into stucco and stone joints is the same problem either way.
