What Window Cleaning Actually Costs in the Treasure Valley

Most Treasure Valley homes land between $199 and about $450 for interior and exterior window cleaning. The driver is pane count, not square footage: a 1,900-square-foot house with grid windows can carry more glass than a 2,800-square-foot one. Screens add $50. Here is the math, and how to check any quote before you book.

From $199

The starting number is $199, and pane count moves it

Window cleaning here starts at $199 for interior and exterior. That covers a real house, not a teaser rate for four windows. From there the price moves on one thing: how many panes of glass a crew has to touch. Square footage is a poor proxy. A 1,900-square-foot ranch with grid windows in every room can carry more glass than a 2,800-square-foot house built around a few large picture windows. Time on the job tracks panes, edges, and setups, so that is what the price tracks. Screens add $50 for the whole house, because they get pulled, washed, dried, and reset, which is genuine labor and not a fee. Hard water stain removal is quoted separately, since it is a different process with a different tool set. Ask any company to split its number into those three buckets before you compare it to anyone else's.

Count your own panes in ten minutes

You can count your own glass before anyone shows up and walk into every quote knowing whether it is fair. A pane is one piece of glass in one frame. A double-hung window with an upper and lower sash is two panes. A slider is two. A picture window is one, no matter how big. Divided lites, meaning the small squares in a grid or a French door, are where companies differ: some price the whole sash as one unit, some count each square. Neither approach is wrong, but you need to know which one a company uses before you set two numbers side by side. Walk the exterior and count by elevation, then walk the interior and note anything blocked by a sink, a bed, or a built-in. Add up the total, add screens, and flag any window you cannot reach from the ground. That single number is what makes quotes comparable.

Why a second story costs more, and when it barely does

Two stories add cost, but less than most people expect, and the reason is access rather than height. Ground-level glass is a squeegee, a towel, and a few steps. Upstairs glass is either a ladder set, carried and footed and leveled and moved every window or two, or a water-fed pole worked from the driveway. Ladder work is slower and it is where injuries happen, so it prices higher. Pole work from the ground is faster and safer, which is why pure water through a pole has become the standard for upper exteriors. What actually spikes a two-story quote is landscaping and grade: window wells, rock beds, a steep slope, a deck sitting under a bank of windows, or glass that can only be reached over a roof pitch. Upstairs windows above flat lawn are a modest bump. Upstairs windows above a hedge on a hillside are not.

The gap between two quotes is usually scope, not price

Before you compare numbers, make each company answer the same six questions in writing. Does the price include interiors, or exterior only? Are screens in or out, and does that mean washed or just wiped? Are tracks and sills cleaned, or does the job end at the glass and leave a wet frame and a gritty channel? Is hard water staining priced now, or will it become a change order at the door? Is the crew insured, and can they send the certificate without a phone call? Is there a minimum, and does your house clear it? A quote reading "$149 whole house" and a quote reading "$249 including screens and tracks" are not the same product. A cheaper number is not dishonest by default. It is often just narrower, and the narrowness tends to surface on job day rather than on the estimate.

A five-point test you can run on any company, including this one

One: will they give you a written number tied to a pane count instead of "call for a quote"? Two: can they name the water and method they use, and does it fit the surface they are using it on? Three: does proof of insurance arrive unprompted? Four: is there a stated policy for rain within the first week, in writing? Five: track record, and this is where Reflekt is honestly behind part of the field. We started in April 2025. There are window cleaners in this valley with a decade of route history and a review file deeper than our 115+ Google reviews, and if longevity is your top criterion, hire one of them with a clear conscience. If a published price structure, a stated method, and same-week availability matter more to you, we are the better fit. Both answers are reasonable.

How Reflekt prices and books the work

Reflekt quotes windows from $199, priced off your pane count, with screens at a flat $50 for the house. We wash with 100 percent pure deionized water and no soap, so glass dries without spots and there is no soap film left behind for dust to grab. We call that finish RainShield. Every job carries a 7-Day Rain Guarantee: if it rains within a week, we come back. Monthly and Quarterly memberships have no contract and include a free annual screen clean. Same-day and next-day slots open most weeks. If you are bundling, gutters start at $199, pressure washing runs $0.20 per square foot, and house washing is $0.18 per square foot soft-wash. Call (208) 453-6760 with a rough pane count and you will get a real number on the phone instead of a scheduled sales visit. Locally owned out of Meridian, fully insured.

How much does it cost to clean windows on a 2 story house in Boise?

Ballpark, most two-story Treasure Valley homes land between $250 and $450 for interior and exterior, with screens adding $50. The spread comes from pane count and access, not from the second story by itself. A 26-pane two-story with clear ground around it often prices under a sprawling single-story carrying 40 panes. Count your panes first and the number stops being a guess.

What counts as one pane?

One piece of glass in one frame. A double-hung window has an upper and a lower sash, so it counts as two panes. A slider is two. A picture window is one, however large it is. Divided lites, the small squares in a grid or a French door, are where companies differ: some price the sash as a single unit, some count every square. Ask which method a company uses before comparing two quotes.

Why do screens cost extra?

Because they are a separate job from the glass. Screens get pulled, tagged so they return to the right opening, washed, rinsed, dried, and reset. On a 25-window house that is close to an hour of work that has nothing to do with cleaning windows. Reflekt charges a flat $50 for the whole house rather than per screen, and membership includes a free annual screen clean. A quote that skips screens is quoting a smaller job.

Is per-pane pricing better than hourly?

For most homeowners, yes. Hourly means you carry the risk of a slow crew, a weather delay, or a hard water surprise, and you do not know the total until the truck pulls away. Per-pane sets the number before anyone arrives, and it only moves if the scope moves. Hourly can make sense on commercial buildings or restoration work, where nobody can predict the condition of the glass until they are up close.

How often should Treasure Valley windows be cleaned?

Twice a year covers most homes here: once after spring pollen and canal-season dust, once before the holidays. Houses with sprinklers hitting the glass need more. Our water is hard, and mineral spray etches if it sits long enough, which is the damage that turns a $199 cleaning into a hard water restoration quote. If overspray reaches your windows, quarterly service is cheaper than repairing the glass later.

Do you charge extra for interior cleaning?

Interior and exterior together is the standard quote starting at $199, priced on total pane count, so interiors are counted rather than surcharged. Exterior-only comes in lower because fewer panes get touched and there is no time spent moving furniture, protecting sills, or working around blinds and window treatments. Ask for both numbers when you call so you can see exactly what the inside work is costing you.
