What Window Cleaning Costs in the Treasure Valley in 2026

The 2026 numbers, by job type

These are Reflekt Window Cleaning's own published 2026 rates, not an industry survey. Window cleaning starts at $199 and is priced by pane count. Screen cleaning adds $50 to a window job. Gutter cleaning starts at $199. Pressure washing is $0.20 per square foot. Soft-wash house washing is $0.18 per square foot. Most single-story valley homes with 20 to 30 panes land near the $199 starting point. Two-story homes in Eagle, Star, and north Meridian with 50-plus panes and grid inserts run well above it. Commercial storefronts and property-manager accounts are quoted per route rather than per address. A flat "$99 whole house" quote almost always means exteriors only, or a fast soap-and-squeegee pass that spots within a week.

Pane count sets the price, not square footage

Window cleaning is priced by pane count because labor scales with the number of pieces of glass, not the size of the house. A 3,400-square-foot home with large picture windows can have fewer panes than a 2,100-square-foot home with divided-light grids in every opening. A pane is one side of one piece of glass in a frame, so a double-hung window with an upper and lower sash is two panes per side, and interior and exterior are counted separately. Colonial and French grid inserts multiply the count fast: one 6-over-6 window is a single opening but twelve small sections to work around. Ask every company for the pane count written on the quote. Dividing the total by that number is the only honest way to compare two bids.

What pushes a Treasure Valley quote above the starting price

Six things move a window cleaning quote up in this valley, and all six are checkable before you book. Second-story glass requires ladder work or water-fed pole reach and adds time per pane. Grid and divided-light windows multiply pane count. Bonded hard water staining is a separate restoration job, not routine cleaning. Screen cleaning adds $50. New-construction homes in Kuna, Star, and south Meridian often carry stucco splatter, concrete dust, and label adhesive that has to come off before glass can be cleaned. Access matters too: landscaping beds, AC units, window wells, and steep grade under a second-story window all slow the work. Track and sill detailing is sometimes quoted separately by other companies, so ask whether it is included.

Hard water staining is the valley's most expensive add-on

Hard water staining is the most common reason a Treasure Valley quote climbs, and pressurized irrigation causes it. Most valley subdivisions irrigate with untreated canal water carrying dissolved calcium and silica. When a sprinkler head throws that water onto glass in July and it bakes dry in 95-degree heat, the mineral bonds to the surface. A routine cleaning does not remove bonded mineral. Removing it takes a separate restoration pass with abrasive compound and real time on each pane. Reflekt quotes hard water stain removal only after inspecting the glass, because six months of light film and four years of daily overspray are different jobs at different prices. The cheapest fix is upstream: re-aim the sprinkler heads hitting your windows. That costs nothing and prevents a restoration bill later.

Interior cleaning costs more per pane than exterior

Interior window cleaning costs more per pane than exterior work because of everything that is not glass. Exterior panes are open access. Interior panes mean moving furniture, handling blinds and shades, laying drop cloths, working around pets and kids, and pulling and reseating screens. On a typical valley home the interior side runs roughly 1.5 times the labor of the exterior side. That is why exterior-only service is the cheaper maintenance option, and why a common local pattern is interior-and-exterior once a year with exterior-only visits in between. Reflekt cleans exteriors with 100% pure deionized water and no soap, so there is no surfactant film left behind for valley dust to stick to, and the RainShield finish helps the glass shed the next rain. Interiors are done by hand, since you cannot flood water down an interior wall.

Frequency, memberships, and the real annual cost

The annual cost of clean windows depends on frequency more than on any single visit price. Treasure Valley glass has two hard seasons: pressurized irrigation runs roughly April through mid-October and puts mineral-bearing water on the glass, and wind off open farm ground drives fine dust into every screen. Twice a year, once in late spring after irrigation starts and once in fall after leaf drop, is the most common homeowner cadence. Reflekt offers Monthly and Quarterly memberships with no contract, which spread the cost and include a free annual screen cleaning. Quarterly is the practical choice for a home with sprinklers near the glass. All work carries a 7-Day Rain Guarantee. Reflekt is locally owned, fully insured, founded in April 2025 by Hunter Stevens and Ethan Seusy, and holds a 4.9-star average across 115+ Google reviews.

When window cleaning is not worth paying for

Some homes should not hire this out, and saying so is more useful than a sales pitch. If you have a single-story home with twelve accessible ground-floor panes, a $30 squeegee and ninety minutes gets you most of the result. If your glass is already pitted, meaning the pane looks hazy from every viewing angle because mineral has etched into the surface, no cleaning restores it and even restoration may only partially improve it. The honest answer there is glass replacement. If you list your house in three days and your sprinklers hit the windows nightly, adjust the heads before you book, or the exteriors will spot again before the photos. Exterior cleaning also stops making sense below about 32 degrees, when water freezes on the glass faster than it can be pulled off.
