The Boise City Canal ends its run out here at Hill Road, and on the older lots that water still arrives by gravity on a rotation. It is untreated and mineral-heavy, so one impact head aimed wrong leaves a tan film and hard white spotting across a whole slider. Then the tap water dries on top of it.
Collister is one of the few pockets in Boise where a house can get spotted by two different water sources in the same week. The Boise City Canal runs from Warm Springs Avenue clear across the old city and finishes out here at Hill Road, so the canal-side properties still hold live ditch rights and flood-deliver on a rotation. That water is untreated. Silt, algae and dissolved mineral come straight out of the ditch, and a head throwing onto the house leaves a gritty tan haze with white spots set into it. The rest of the neighborhood is on Veolia tap, and the well-fed west side of Boise tests at the hard end of the 10 to 13 grain range. Neither one rinses off on its own. Both dry into calcium. We wash with 100% pure deionized water, stripped of every mineral, so there is nothing left on the glass to dry into a spot.
Collister sits at the bottom edge of the Boise Front, and the air that drains off the foothills at night carries decomposed granite dust down over these blocks. It is pale, fine and sharp-edged, nothing like the soft plowed-field silt that dirties the west end of the valley. It settles heaviest on north-facing glass, which stays shaded and holds moisture longer, so the grit sticks there instead of blowing back off. The part worth knowing is that this dust scratches. Wiping a dry north window with a paper towel drags granite across the pane and leaves fine arcs that show up every time the low sun catches them. We flood the glass first and let the water float the grit off, then work it with soft bristle and rinse. The dirt leaves in the water, not under a cloth.
Collister is not one housing era, and treating it like one gets a quote wrong. Most of the neighborhood is 1950s through 1970s ranch: mill-finish aluminum sliders, a wide living-room picture unit, low pitch and short eaves. Those frames chalk as the finish gives out, and the powder sitting in the bottom track will print gray lines across a pane you just finished, so tracks get flushed and wiped before a squeegee touches glass. Then there are the older places along the ditch on big lots under trees that were mature before the tract blocks went in. Painted wood sash, some divided lite, storm windows still in service, glazing putty that has dried and shrunk. Those do not get handled like a vinyl slider. Less pressure, no blade as a matter of routine, and hand-drying at the sash joints. Tell us which one you have when you call and the number will be right.
The original houses out here still carry half-round hung gutter, some of it four inch, sized for a roof and a canopy that were both smaller than they are now. A half-round drains to a round outlet and a drop tube, and that outlet plugs on one wad of wet maple leaves in a way K-style never quite does. The water then backs up over the front bead and runs down the fascia instead of overflowing where you would notice it. October is when it happens, because the mature trees on the canal lots drop everything inside about three weeks. Gutter cleaning starts at $199. We hand-scoop into a bucket rather than blowing debris into the beds or the ditch, flush every downspout to confirm it actually runs, and tell you if a section is undersized or back-pitched instead of clearing it again next fall.
The lots out here run bigger than the Boise average, and that changes the work more than the house does. Plenty of these places have a shop or detached garage set well back, a long gravel drive, a board or chain-link gate, and a dog with the run of the yard. Mature maples and spruce stand close enough to the walls that a water-fed pole cannot get a clean line to the upper glass, so we reposition instead of forcing the angle. Then there is the ditch bank, which looks solid and is soft underneath. Ladder feet do not belong on it, so those elevations get worked from the lawn side or off a standoff. The one thing that genuinely helps us is knowing your irrigation day. If the rotation puts water on your yard the afternoon we are scheduled, say so when you book and we will take a morning slot instead.
Window cleaning starts at $199 and prices by pane count rather than square footage, so a long 1960s ranch with six sliders and a picture window can come in under a smaller house cut into small lites. Screens are $50 to pull, wash and reinstall, and they matter here, because grit and canal silt load the mesh until a clean window still reads gray from inside. Gutters start at $199. Pressure washing is $0.20 per square foot on drives, walks and patios. House washing is $0.18 per square foot on a soft-wash setting that suits painted lap siding and older mortar. Memberships run Monthly or Quarterly with no contract, Quarterly saves $100 per cleaning and includes a free annual screen clean, and every job carries the 7-Day Rain Guarantee.

It depends how long they have sat. Fresh mineral from ditch or tap water comes off with our normal deionized wash. Spotting that has baked through several Boise summers starts to etch into the glass surface, and etch is damage rather than dirt, so no cleaner takes it out. We test a corner and tell you which one you are looking at before we quote it. Either way, the long-term fix is aiming that head off the house.
Yes, and you can see the difference. Veolia tap dries as clean white mineral spotting. Canal water carries silt and algae along with the mineral, so it leaves a tan or greenish film with hard spots set into it, and it is always worst on the lower third of the window where the head reaches. Ditch water also loads screens much faster. Homes on a flood-delivered rotation usually want screens done more than once a year.
Quarterly suits most of the neighborhood. You are catching foothills grit off the Hill Road edge in spring and fall, dust baking on through a rainless summer, and an irrigation season that runs April into October. Quarterly saves $100 per cleaning against one-off pricing and includes the annual screen clean. Monthly is worth pricing if you have a ditch-fed system throwing onto the house or a wall of glass you look through every day.
Yes. They get cleared by hand like any gutter, but the outlets need checking specifically. A half-round drops into a round outlet and a tube, and that is the piece that plugs first. We flush each one after scooping to confirm water is actually moving through. If a run is back-pitched or the gutter is plainly undersized for the canopy above it, we will say so, because clearing it every October is treating the symptom.
Windows start at $199 and go by pane count. A single-story ranch with a picture window and five or six aluminum sliders usually lands near the low end. An older canal-side place with divided-lite sash and storm windows prices higher, because every lite gets cleaned individually and the storms come off and go back on. Count your panes, counting each slider as two, and call (208) 453-6760 for a real number.
Only the zone that actually reaches the house, and only for a day or two after we clean. That gives the RainShield finish a chance to set without mineral drying on top of it. Rain is not the problem. The 7-Day Rain Guarantee covers spotting from rain within a week of a cleaning and we come back and re-clean at no charge. Sprinkler and ditch water is the thing worth timing around, since it spots within hours.
