Spring in Boise arrives with two things that land directly on glass: cottonwood fluff off the Greenbelt corridor and a heavy tree-pollen load through April and May. Add the Boise City, New York, and Ridenbaugh canals coming back online in mid-April, and you get the messiest window month of the year — which is also, paradoxically, the worst month to clean early.
The cottonwood gallery along the Boise River Greenbelt is one of the oldest stands on the whole system, and it releases seed fluff for a few weeks from mid-May into June. Fluff sticks to anything with static or overnight moisture on it, and glass cleaned at the front of that release gets covered again within days. The practical move in Boise is to let the drop finish, then clean once, rather than paying twice for the same windows three weeks apart. Screens catch it worse than glass does — cottonwood mats into the mesh and keeps shedding onto the pane behind it every time the wind moves, which is why adding screen cleaning during this stretch, rather than skipping it to save $50, is usually the better call.
Tree pollen in the valley — heaviest off the maples, oaks, and birch that line North End and East End streets — does not sit loose on glass the way road dust does. Once it gets damp from an overnight dew or a light shower, it bonds into a yellow-green film that a garden hose smears rather than removes. That film is one of the clearer cases for pure deionized water, which lifts it and rinses without leaving soap residue for the next round of pollen to stick to. On original wood-sash windows common through the North End and East End's historic districts, that matters even more, since scrubbing a bonded film with anything abrasive risks the frame and old glazing putty around the pane, not just the glass itself.
Irrigation across the valley comes back on around mid-April, when the Boise City Canal, which runs from Warm Springs Avenue out to Collister and Hill Road, and the New York and Ridenbaugh canals feeding Southeast and Southwest Boise, recharge for the season. The first few weeks are when misaimed heads show themselves, because nobody has watched the system run since October, and that first flush is also the siltiest water of the year. Walking the yard during a cycle in late April and re-aiming anything hitting glass saves more window cleaning over the summer than any product will — Boise tap water already runs 10 to 13 grains hard, and canal water on top of that is what actually etches glass by August, not the tap alone.
Spring is the right time for gutters, because the winter's worth of needles and grit is already sitting in them and spring rain needs somewhere to go. It's also when elm samaras and maple keys, the small winged seeds that spin down through April, add a second load on top of whatever leaves overwintered in the trough. And it's the right time to catch what winter did to the house: north-facing algae under the North End and East End canopy, salt splash at the base of the siding from road brine, and anything the freeze-thaw cycle loosened on foothills-facing stucco or trim.
Windows start at $199 and price by pane count; screens are +$50 and clean free once a year on a membership. Gutters run from $199, pressure washing is $0.20 a square foot, and soft-wash house washing is $0.18. Every visit finishes with 100% pure deionized water and no soap — the RainShield finish — backed by a 7-Day Rain Guarantee. Memberships are Monthly or Quarterly with no contract; Quarterly saves $100 per cleaning and lines up naturally with Boise's spring canal turn-on and fall leaf drop.

After the Greenbelt cottonwood release finishes and the heaviest tree pollen has passed, generally mid-to-late May. Cleaning before that usually means paying for the same windows twice, since fresh fluff and pollen recoat glass within days of the drop starting.
Not always, but once pollen off North End and East End maples and lindens has been rained on and dried, it forms a bonded film rather than loose dust. That's when a hose makes it worse and pure deionized water makes the difference, especially on older wood-sash glass that shouldn't be scrubbed.
Both if the house sits under mature trees, but spring is non-negotiable in Boise because winter debris plus April's elm samaras and maple keys are already packed in, and spring rain needs the path clear.
Yes, and we'll tell you honestly that it may not stay clean long. Some customers need it done for an event, and that's a fine reason to go ahead anyway.
Generally mid-April, when the Boise City Canal and the New York and Ridenbaugh systems recharge for the season. The first few cycles are the best time to walk the yard and check where heads are actually throwing, since that first flush carries the siltiest water of the year.
Window cleaning starts at $199 and is priced by pane count. Screens are $50 more, gutters start at $199, and Quarterly membership saves $100 per cleaning with no contract.
