Two days after the house wash, the late sun came around to the west side and every window looked like frosted glass. The soft wash crew had warned me. They rinse the outside of the glass as part of the job, a rinse leaves spots, and window cleaning is its own line of work. Our clean cream siding now framed eighteen windows that looked worse than before.
I started calling around the next morning, and window cleaning services prices turned out to be almost never per window. A phone quote of “$6 a window” became $408 at my front door. I ended up paying $366, for a job I had guessed would cost $108.
How many windows I thought I had
If you read the pressure washing post, you know the house: built in 1996, mostly one story, with a two-story gable over the front door. Before I called anyone I went through every room with a notepad and counted. Eighteen windows, counting the sliding patio door.
Fourteen of them are double-hung, the kind with a top half and a bottom half that slide past each other. There’s a wide picture window in the living room and a small slider over the kitchen sink. And there’s one half-round window high above the front door that nobody in this family has ever cleaned. I doubt the previous owners did either.
Eighteen felt manageable. None of the three companies I called ended up quoting that number.
Why window cleaning services prices are counted by the pane
A double-hung window has two sashes, and each sash holds its own piece of glass. To a window cleaner, that’s two panes. The kitchen slider is two panes, and so is the patio door. The picture window and the half-round count as one each. Added up, my eighteen windows became 34 panes.
Every pane also has two sides. Some companies charge per pane per side, which makes the inside and the outside separate line items. Others quote per pane with both sides included. Both are honest ways to price a job, and they produce very different totals from the same few words on the phone.
Grids change the count too. Ours have grids sealed between the two layers of glass, and the crew said those cost nothing extra because the surface they clean is smooth. Snap-in grilles that have to come out, or old windows built from many small separate panes, get counted piece by piece. A window with a dozen little panes can bill like six plain ones.
Then height. The crew I hired charges $9 a pane for anything they reach from the ground or a short stepladder, and $12 upstairs, where the extension ladder or the water-fed pole comes out. On a true two-story house that difference lands on half the glass. On ours it touched one window.
Window cleaning services prices from my three quotes
These came from one suburb in September 2026. Prices move a lot by region, so use them to see how a quote gets built rather than as a going rate.
The first was a man from our neighborhood group. On the phone he said $6 a window, and I did the math in my head: 18 times $6, or $108. When he came by to look, his $6 turned out to mean per pane, per side. Outsides only came to $204. Inside and out was $408, with screens extra. The mix-up was mine. I heard “window” and he meant “pane.”
The second was a local company that has done windows on our street for years. They price per pane with both sides included, $9 on the ground floor, which put our 34 panes at $306. The half-round added $20, because the inside needs a tall ladder in a two-story entry and the outside needs a pole.
Their written quote then added three optional lines: a full wash of all 16 screens at $4 each, track and sill cleaning at $3 a window, and hard water treatment on four panes at $10 each. With all of it, $478.
The third company only does outsides, with a water-fed pole: a long brush that sprays purified water, so the glass dries without spots and nobody climbs anything. They quoted $4.50 a pane, or $153, and pitched a plan of two exterior visits a year for $280. No inside work at all.
I booked the second company for the panes, the high window and the hard water, $366 in total. Two of them were in and out in two hours and twenty minutes, and every screen went back into the window it came out of.
Screens, tracks and hard water get priced on their own
Screens are the line people forget. The basic job at my company included pulling them, brushing off the dust and wiping the frames. A real wash with soap and water was the $4. I did that part myself on the driveway with dish soap, a soft brush and the hose. Sixteen screens took about 45 minutes, and they dried on the lawn.
Tracks are the grooves the sashes slide in, plus the sill under them, where grit and dead bugs collect. At $3 a window it’s a fair price for a gross job. I did ours with the vacuum’s crevice tool and an old toothbrush in 50 minutes, and next year I’ll pay someone.
The hard water I couldn’t have done myself. The four panes facing the side yard get hit by the lawn sprinkler every summer morning, and the minerals had baked into white rings. The fresh spots from the house wash came off with the regular cleaning. The sprinkler rings needed a separate treatment, and the crew lead did one pane first and showed me the difference before touching the rest. Four panes at $10 is the $40 on my bill.
Ask about all three before the day of the job. On my full quote they added $152 to a $326 base.
| Window on my house | How many | Panes each | Panes counted | At $9 a pane, inside and out |
|---|---|---|---|---|
| Double-hung (bedrooms, kitchen, dining room) | 14 | 2 | 28 | $252 |
| Living room picture window | 1 | 1 | 1 | $9 |
| Slider over the kitchen sink | 1 | 2 | 2 | $18 |
| Sliding patio door | 1 | 2 | 2 | $18 |
| Half-round over the front door | 1 | 1 | 1 | $9, plus $20 for the tall ladder |
| Total | 18 | 34 | $326, then $40 of hard water treatment = $366 |
Common mistakes when comparing window cleaning services prices
- Multiplying a phone price by your window count. My $108 guess and the $408 quote came from the same “$6.” Ask whether it’s per window, per pane, or per pane per side, and get the answer in writing.
- Booking the windows before the house wash. A house wash rinses the glass and leaves mineral spots behind. I scheduled the windows for the week after, and I’d keep that order.
- Paying for extras you can do in an afternoon. Screens and tracks were $112 of my $478 quote, and they’re the easy parts to keep for yourself.
Inside and out, or outside only, and how often
The outside-only plan was the cheapest per visit, and for plenty of houses it’s the right call. The outside collects pollen, rain splash and spider webs. The inside gets fingerprints and a film from cooking, and a damp cloth on a rainy afternoon takes care of most of it.
The crew lead suggested outsides twice a year, once in spring after the pollen and once in fall, with insides once a year. I settled on one full inside-and-out visit each September, right after the house wash. The ground-floor outsides I’ll do myself in spring, which I could only plan once I found a latch I didn’t know my windows had.
Whatever schedule you pick, pin it to something you already do. Mine sits on the same page as the gutters and the furnace filter in my fall cleaning checklist, and the smaller repeat jobs live on my deep cleaning schedule.

What didn’t work: a Saturday with a squeegee
Last September I decided to do it myself. I bought a $22 kit with a squeegee, a scrubber and an extension handle, mixed vinegar and water in a bucket, and started at 9 a.m.
By 4 p.m. I had finished the ground floor and hadn’t touched the high window. The west-side panes streaked as soon as the afternoon sun hit them, because the mix dried before I could squeegee it off. I bent a screen frame prying it out, and the replacement cost $18 at the hardware store. To reach the top of the kitchen window from outside, I stood on the top step of my six-foot stepladder over the flower bed.
I shouldn’t have. OSHA’s portable ladder safety card says not to use the top step or rung as a step unless the ladder was designed for it, and to keep three points of contact while you climb. I had one hand on the squeegee and the other flat on the glass.
Two months later, reaching up to shut the kitchen window for winter, I noticed two small latches at the top of the lower sash. Our double-hung windows tilt in. You slide the latches, the sash swings into the room, and you clean the outside of the glass standing on the kitchen floor. They had been doing that for 30 years and nobody had told me.
That Saturday cost me $40, seven hours and a stiff back, and the windows still looked worse than they do after the crew’s two hours and twenty minutes. The $366 paid for the one window I can’t reach, the sprinkler rings and a finish without streaks. For the easy panes I still do, New Mexico State University’s green cleaning guide has a plain vinegar-and-water mix and a trick I use each time now: wipe the inside in one direction and the outside in the other, so you can tell which side a streak is on.
Frequently asked questions
How much do window cleaning services cost for a whole house?
For our 18 windows, which came to 34 panes, my three quotes in 2026 ran from $153 for outsides only to $408 for inside and out, and $478 with every add-on. I paid $366. The pane count, the number of high windows and the extras you pick move the price more than the size of the house does.
Why do window cleaners charge per pane instead of per window?
Because one “window” can be a single piece of glass or twelve. Counting panes lets them price a double-hung window with two sashes differently from one picture window. Ask whether the per-pane price covers one side or both.
Is it worth paying for screen and track cleaning?
If you’re short on time, yes. My company charged $4 a screen and $3 a window for tracks, $112 for the whole house. I did both myself in about an hour and a half. Next time the tracks go to the crew.
The most useful ten minutes of this whole project were spent with a notepad, counting glass instead of windows. Do that before the first phone call and circle the panes you can’t reach from the floor. Every quote you get will then line up against the same number, and the “$6 a window” line won’t surprise you the way it surprised me.
