Randolph-Robertson's low ranches carry the biggest unbroken panes on the Boise Bench — floor-to-ceiling atomic-ranch glass and corner windows with no mullions to hide a streak. Add Gowen Field's jet soot and aphid honeydew off the Bench canopy, and one missed pass shows under the first low winter sun.
Randolph-Robertson is Boise's clearest concentration of true mid-century modern design: low 3:12 to 4:12 rooflines, brick and painted lap siding, and window openings sized to show off the house instead of just letting in light. That means wide single-pane picture windows, glass corners with no vertical mullion between them, and banks of jalousie louvers on the original ranches — a different job than the small divided-lite sash we clean in the North End or the plain aluminum sliders on an ordinary Bench rambler. A six-foot picture window has nowhere for a streak to hide; the whole pane reads as one surface, so a squeegee pass that leaves a hairline on a nine-lite Craftsman window is obvious across an entire wall of an atomic ranch. We work these panes edge to edge with a single pull whenever the glass size allows it, because breaking a big MCM window into sections is exactly where seams and streaks show up.
Randolph-Robertson sits in the same Bench corridor as Depot Bench, Vista, Hillcrest and Morris Hill, which puts it under the Boise Airport and Gowen Field flight path — jet soot lands here that the foothills neighborhoods never see. Traffic film off Vista Avenue and Fairview adds a greasy haze on street-facing glass, and the mature street trees that have grown up over these low rooflines carry the same aphid populations that mist honeydew onto the North End: a sticky film that plain hose water won't budge. Winter is worse on low glass than tall glass. December through February inversions trap wood smoke and particulate low in the valley bowl, and because these ranch picture windows sit close to grade instead of two stories up, they catch more of that settled film than an upper-story window would. It only shows once the low winter sun rakes sideways across a six-foot pane — which is usually the moment a homeowner calls.
Most of the Boise Bench runs on Veolia Water Idaho, blended from Boise River surface water and more than eighty deep wells, and the well-fed side of that supply commonly tests harder than the water downtown — often 10 to 13 grains per gallon. Run that through a sprinkler head onto a big single-pane window and it flash-dries into a spotted mineral film before anyone notices the overspray. On a divided-lite sash the spotting hides in eight small panes; on an atomic ranch's floor-to-ceiling glass it reads as one continuous water-stained sheet. We clean with 100% pure deionized water and no soap, so there's no mineral left in the rinse to dry into a spot and no soap film to attract the next layer of dust. That matters more here than almost anywhere else on the Bench, because these homes were built to be looked through, not just at.
The low 3:12 to 4:12 rooflines and short eaves that define Randolph-Robertson's ranches are actually easier on a ladder than the steep, two-story bungalows in the North End or East End — most of this glass and gutter line sits within normal ladder reach instead of requiring extension work over a porch roof. The trade-off is the glass itself: corner windows with no frame between two panes need to be worked as a single continuous line so the seam doesn't show, and original jalousie louvers have to be cleaned slat by slat rather than in one squeegee pull. Aluminum sliders on the additions and later remodels get a standard interior-and-track clean plus a screen pull, since screens on these older aluminum frames tend to hold more grit than newer vinyl track systems. We carry both approaches to the same appointment, because most Randolph-Robertson houses have some mix of original MCM glass and later aluminum replacement units.
A house with this much unbroken glass shows dust faster than one with small divided lites, which is why quarterly or monthly service makes more sense here than a once-a-year clean. Quarterly membership saves $100 per cleaning compared to booking one-off visits, there's no contract, and every visit includes a free annual screen clean for the jalousies and sliders that collect Bench grit. If wind or a late sprinkler cycle undoes the work before you've had a chance to enjoy it, the 7-Day Rain Guarantee covers a return visit at no charge. We book same-day and next-day slots across the Bench, and because Randolph-Robertson sits close to our regular Central Bench and Vista routes, scheduling around a specific low-sun afternoon — when streaks on these picture windows are most visible — is usually easy.

Because the glass itself is bigger. A typical mid-century picture window here runs floor-to-ceiling in one unbroken pane, so a squeegee seam or a missed corner reads across the whole wall instead of hiding inside a small pane. We clean these edge to edge in as few passes as the glass size allows, which is the main reason streaks are less likely to show once we're done.
Yes. Original jalousie louvers on unrenovated Randolph-Robertson ranches get cleaned slat by slat by hand, since a squeegee can't work the angled glass the way it works a flat pane. It takes longer per window than a standard slider, and we account for that in the estimate rather than rushing it.
It's part of our regular Central Bench and Vista service area, so same-day and next-day slots are usually open. Quarterly members get first pick of scheduling, which matters most during spring irrigation turn-on and fall leaf-drop, when the whole Bench calls at once.
We run 100% pure deionized water with no soap. There's no mineral content left to dry into a spot the way Boise's 10-13 grain tap water does, which is the main reason it works on large single-pane glass without leaving the streaked, water-stained look sprinkler overspray causes.
Yes, one visit covers the whole house. We price by pane count across window and screen glass regardless of frame type, so the mix of original picture windows, corner glass, and later aluminum sliders common on Randolph-Robertson remodels gets quoted together, not as separate jobs.
It does. Homes on this stretch of the Bench pick up more jet soot and traffic film than foothills neighborhoods further from Gowen Field, and it shows fastest on street-facing glass. Most Randolph-Robertson customers land on quarterly service rather than an annual clean once they see how fast that film returns.
