What needs washing off a house in Laguna Pointe is not really dirt. genuine algae growth on the shaded and water-facing walls, not just dirt.
River humidity plus a 43-acre lake means the shaded elevations here stay damp most of the day through spring and autumn, and damp plus organic debris is exactly what algae and mildew need. The north and water-facing walls green up in a way a dry Eagle lot never does. That growth has a root structure in the surface, so blasting the visible layer off means it returns within weeks. A soft-wash solution treats the growth itself, which is the difference between clean for a season and clean for a fortnight.
Estate elevations mix materials — stucco fields, stone wainscot, timber accents, sometimes brick — and they do not all wash the same way. Stone and its mortar joints hold grit in the texture; stucco is porous and unforgiving of pressure; timber and painted trim want the gentlest treatment of all. Soft-washing at $0.18 per square foot handles the mix with low pressure and dwell time rather than one aggressive setting applied to everything. On a house this size we walk the elevations first, because quoting square footage sight unseen would be guessing.
The consistent problem on large landscaped lots is not the whole wall — it is the bottom three feet of it. Untreated canal irrigation throwing at stone wainscot and stucco leaves a gritty tan mineral band that reads as dinginess and does not rinse off. That band frequently needs different attention than the rest of the elevation, and sometimes the honest advice is to adjust the sprinkler heads first, because otherwise you are washing the same band again next year.
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. Lots here run three-quarters of an acre to two and a half, so equipment lines reach farther from the truck than on a standard lot.

Because the visible layer came off and the root structure in the surface did not. Growth on a damp shaded wall needs a solution that kills it, not pressure that strips the top. That is the whole distinction between soft-washing and blasting.
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.
