The Highlands was built to look at the valley, so the glass here is wide, horizontal and fixed — bands of picture units across the downhill side of split-levels and daylight basements off Bogus Basin Road. None of it opens. All of it collects decomposed granite dust off the Boise Front.
The dust that lands on Highlands glass comes off the Idaho Batholith, not off a farm field. Decomposed granite is quartz and feldspar broken down into pale, sharp-edged grit, and the nightly downslope air out of Crane Creek and Hulls Gulch carries it onto north- and east-facing windows. It looks harmless — a light chalky haze — which is exactly why people wipe it with a dry paper towel and put fine scratches across a picture window they cannot replace cheaply. We flood the pane first and let the water carry the grit off before a brush ever touches it. The wash is 100% pure deionized water with no soap, which matters here more than most places: soap leaves a tacky film, and a tacky film on abrasive granite dust is a grinding paste on your next windy night.
Most of the Highlands went up between about 1960 and the mid-1980s, and the design brief was the same on nearly every lot: put the living space on the downhill side and glaze the whole wall. What that leaves us is long horizontal bands — a big fixed picture unit with narrow flanking sliders or awning vents, often in thin aluminum frame on the older houses and wood-clad or early vinyl on the eighties builds. The fixed panes do not open, so there is no cheating them from inside with a rag. They also carry the view, which means every streak shows against the valley the moment the sun drops behind the ridge. We work those bands in full passes across the whole run rather than pane by pane, so the finish matches end to end instead of showing a seam every four feet.
A daylight basement is one story from the street and three from the bottom of the yard. Stand a ladder on that lower grade and you are footing it on loose decomposed granite over a 20 to 30 percent slope, which is how people get hurt. On most Highlands houses we work the downhill elevation from the ground with a carbon-fiber water-fed pole, so nothing is leaning on the siding and nobody is standing on a slope with a squeegee. Where a pole cannot get the angle — deep soffit returns, glass tucked under a cantilevered deck — we use leveling ladder feet off a hard surface, or work from the deck itself. Driveways up here are short and steep and the streets off Bogus Basin Road are narrow, so we park once, tight to the curb, and carry in.
Two things drive the Highlands calendar. First, snowmelt: when the hill lets go in March the runoff sheets silt down the pavement and the wind puts it right back on the lower band of glass, so an early-spring cleaning often has to be redone or timed for after the melt rather than during it. Second, the inversion. Boise sits at the bottom of the bowl and the winter wood-smoke layer has a ceiling. Some weeks that ceiling is below the Highlands and you are in clear sun while the Bench is gray; other weeks it caps out above you and your windows take the same PM2.5 film everyone else gets. That is why the winter pattern here is uneven — upper streets and lower streets on the same hill do not always dirty at the same rate, and we would rather look at your actual glass than guess.
Down in the North End and along Hill Road, half the hard-water damage we see comes off gravity ditch water from the Boise City Canal — silty, untreated, mineral-heavy. Most of the Highlands sits above that canal line, so irrigation up here is pressurized municipal water from Veolia, which commonly runs 10 to 13 grains per gallon. It is cleaner than ditch water and it still spots badly, because at 100 degrees and ten percent humidity the droplet flashes dry on the glass and leaves the calcium behind. A head throwing onto a lower window band all summer will build a scale ring you can feel with a fingernail. Pure deionized water is the fix on both counts: nothing dissolved in it, so nothing is left on the pane when it dries. That is the RainShield finish — no soap, no residue, nothing for the next dust load to stick to.
Window cleaning starts at $199 and prices by pane count, which suits these houses: a Highlands split-level with four big fixed units and a few sliders often prices under a same-size Bench ranch with twenty small openings. Screens add $50. Gutters start at $199 — worth pricing here because foothills gutters fill with pine and juniper needle plus granite grit, which packs into a wet sludge rather than blowing out. Pressure washing runs $0.20 per square foot; house washing is soft-wash at $0.18. Memberships are monthly or quarterly with no contract, quarterly saves $100 a cleaning, and members get a free screen clean once a year. Every job carries a 7-Day Rain Guarantee, which is not a small thing on a hill where a March squall can put the whole slope back on your glass.

Windows start at $199 and price off pane count, not square footage. That works in your favor on a view house — a wall of four large fixed units counts as four panes, even though it is thirty feet of glass. Screens are $50 more. Give us a rough count of openings, or a photo of the downhill elevation, and we can price it over the phone at (208) 453-6760.
Yes, and usually without putting a ladder on the slope. A water-fed pole reaches roughly three stories from level ground, which covers the downhill wall on nearly every Highlands lot we have worked. If the grade is too broken to stand on at all, we work from the deck above and pole down. If we genuinely cannot reach something safely, we will tell you before we start rather than after.
No, and we will not charge you to try. A lot of Highlands glass is original 1970s and 1980s insulated units, and after forty-odd years of foothills sun the edge seal fails and moisture gets into the airspace. The tell is a haze or mineral bloom that stays put when you clean both faces, often worse at the bottom of the pane. That is a glass replacement, not a cleaning. We will point it out and leave it alone.
You can rinse the loose layer, but hose water is Veolia tap at 10 to 13 grains, so it dries into spots on top of what you just rinsed. The bigger risk is the dry wipe afterward. Decomposed granite is sharp — it is broken quartz and feldspar, not soft farm silt — and dragging a towel across it puts hairline scratches in the glass that show every time the light rakes across.
Late April into May, after the snowmelt silt has run off the streets and after the mid-April irrigation turn-on has pushed its dirtiest first water through every head. A second pass in late September clears summer sprinkler scale and any wildfire ash before the low winter sun starts raking your valley-facing glass and showing everything. Quarterly members get put on that rhythm automatically.
Yes. Gutters start at $199, and foothills gutters are their own job — pine and juniper needle plus granite grit compacts into a heavy wet sludge that will not blow out, so it gets scooped and flushed. House washing is soft-wash at $0.18 per square foot, which is the right method for the T1-11, cedar and painted lap siding common up here. Pressure washing for drives and patios is $0.20 per square foot.
