What needs washing off a house in Brookwood is not really dirt. green and grey film on the north and east walls that never see direct sun.
Under canopy this mature the shaded elevations barely dry out, and damp plus organic debris is what algae and mildew need. The north and east walls green up while the sunny elevations on the same house can look fine — that asymmetry is normal here and it means a whole-house wash is often not what you need. Sometimes it is two elevations, and we will quote it that way rather than charging for square footage that does not need doing.
Under mature canopy the north and east elevations barely see direct sun, so they stay damp and grow the green and grey film that owners usually assume is dirt. It is biological rather than particulate. Meanwhile the sunny elevations on the same house can look fine. That asymmetry is normal here and it means a whole-house wash is often not what you need — sometimes it is two elevations, and we will say so rather than quoting the full square footage.
Aphid honeydew misting down from the canopy leaves a tacky film that everything else sticks to, and the siding on older homes here — T1-11, hardboard, painted lap — is exactly the material a pressure washer ruins. Hardboard swells from the inside once water gets behind it and the damage shows up a season later as a soft, bubbling board. Soft-washing at $0.18 per square foot is the right call on any of it, and on genuinely old siding we will tell you honestly if washing is going to expose failing paint rather than improve it.
House washing is $0.18 per square foot on a soft-wash setting — low pressure with solution dwell doing the work, which is the right method for stucco, fiber cement, LP-style siding, painted lap and brick alike. Pressure washing at $0.20 per square foot is for flatwork only: driveways, patios and walkways, never siding. Fishing ponds and a community pool inside the neighbourhood keep the air damper than the new-build streets nearby.

Frequently not. Under canopy the north and east elevations are the problem and the sunny sides can be fine. We will walk it and quote the elevations that actually need it rather than the full square footage.
It is the safe option — that is the point of it. Soft-washing uses low pressure and lets the solution do the work, so nothing is driven behind a lap or into stucco. What is not safe is a pressure wand on siding, which forces water behind the surface where it swells hardboard and rots sheathing out of sight.
Kill it. Green and black growth on a shaded wall has a root structure in the surface, so blasting the visible layer off means it returns within weeks from what is left. The soft-wash solution treats the growth itself, which is why it stays clean for a season rather than a fortnight.
We rinse plantings before and after and keep the solution off anything sensitive. Tell us about anything you are particularly protective of at the quote — a specialty plant, a new bed, koi in a pond — and we will plan around it rather than working it out on the day.
Yes — Eagle is one of our nine Treasure Valley cities and we run it as a regular route rather than a stretch call, from the Chinden edge up into the foothills. Call or text (208) 453-6760 and we will tell you the next open slot.
Our 7-Day Rain Guarantee covers it. Rain on a clean surface is largely harmless — it is the dust it lands on that spots. If a storm genuinely undoes the work inside seven days, we come back out.
