How Much Does Window Cleaning Cost in Kent, WA?
Window cleaning in Kent, WA is quoted by the pane, not by the hour — $150–$450 for a one-time whole-house clean, or roughly $10–$14 a pane exterior-only and $18–$24 a pane for both sides. That is the Puget Sound / South King County regional band applied to Kent homes, not a Kent-verified rate.

Kent is King County's valley city of roughly 133,000 people, wedged between Renton to the north and Auburn to the south. Downtown Kent and Kent Station sit on the flat Green River valley floor along with Riverview and Midway, while Scenic Hill, Mill Creek, East Hill, Panther Lake, East Hill-Meridian and Lake Meridian climb the ridges on either side — hill terrain, not valley-floor flat. None of that changes the rate card, though, because window cleaning here is quoted per pane and by story count rather than by neighborhood. That is why two Kent homeowners with the same window count can be quoted very different numbers for what they both call "getting the windows done": one has every pane reachable from the ground, and the other has upper-story glass that needs a ladder or a water-fed pole. Below you'll find 2026 per-pane and whole-house pricing broken out by home size and story count, an illustrative both-sides example, the add-ons that actually move a total (screens, tracks and sills, hard-water removal, height access), Kent's 10.40% sales-tax line, the ZIPs local crews cover, and a month-by-month calendar tuned to the roughly 39 inches of rain this part of the Puget Sound lowlands gets each year. Two caveats first. The $150–$450 headline is the typical mid-size job — a small condo can land on the $100–$175 minimum service charge, and a large two-story home with 25+ panes done on both sides runs well above the band. And there is no Kent-only window-cleaning price dataset: every figure here is the Puget Sound / South King County regional band applied to Kent homes, so treat it as a planning range, not a price a contractor has committed to.

What's Included in a Standard Kent Window Cleaning Service
A standard Kent window-cleaning visit is priced per pane and scoped as exterior-only, interior-only, or both sides. Here's what a both-sides clean normally covers, and what gets quoted separately:
- Exterior glass hand-washed and squeegeed on every accessible pane
- Interior glass on those same panes when you book the both-sides scope (roughly 1.5–1.7× an exterior-only clean of the same home)
- A wipe of the frame edges and sill face as each pane is finished — full track-channel detailing is a separate add-on
- Screen removal and reinstallation so the glass can be reached; cleaning the screens themselves is a per-screen add-on (about $2–$5.50 each)
- Ladder or water-fed-pole access for any upper-story glass, billed as a height surcharge (about $3–$6.50 per upper pane, or 25–55% on base labor)
- A final daylight walk-and-check for streaks and missed spots
- Quoted separately, not included by default: track & sill detailing (about $5–$10 per window, or a flat charge near $75), hard-water and mineral-stain removal (about $40 per affected pane), skylights ($25–$45), bay or picture windows ($15–$25), French doors ($20–$40 per side), and sliders ($15–$30)
Compare Window Cleaning Companies in Kent: Pricing Models
Residential window cleaning around Kent is quoted per pane, with a floor for small jobs. These are the pricing structures you'll be offered:
| Pricing Model | Typical Price | Best For | Trade-offs |
|---|---|---|---|
| Per pane — exterior only (single side) | $10 – $14 per pane | Maintenance cleans, single-story homes, and rentals where nobody needs to be home | Interior glass stays as-is; a whole-house exterior clean typically lands around $100–$760 depending on pane count and story |
| Per pane — both sides (interior + exterior) | $18 – $24 per pane | The annual deep clean, a post-winter refresh, or a home going on the market | Runs about 1.5–1.7× an exterior-only clean and needs interior access to every room |
| Minimum service charge | $100 – $175 flat | Kent Station-area condos, townhomes, and small jobs under roughly 10 panes | A very small job pays the floor regardless of the pane math, so it's worth adding screens or track detailing to the same visit |
| Spring + fall maintenance plan — 2 visits per year | $245 – $2,400 per YEAR total for 2 both-sides visits (this is not a monthly plan) | Kent homes that pick up fir and grass pollen in spring and road grit through the wet season | You get roughly 8–15% off each visit but commit to both; quarterly service is an upsell for high-pollen or near-construction homes, not the standard cadence here |
How to Save Money on Window Cleaning in Kent
Alternate a both-sides clean with an exterior-only refresh
Exterior-only runs about $10–$14 a pane against $18–$24 a pane for both sides, and the outside glass is what collects Kent's winter grit and spring fir pollen. Book both sides once a year and an exterior refresh in between.
Take the spring + fall plan instead of one-off calls
Recurring customers typically get about 8–15% off each visit, putting a two-visit year at roughly $245–$2,400 total depending on home size. That is a two-visit annual figure, not a monthly charge.
Count your panes before you call
Quotes are built from pane count, story count and scope, so a phone estimate given without those three numbers will move once the crew arrives. Small jobs are also floored at a $100–$175 minimum, so a five-pane call-out can cost what ten would.
Pick the flat track-and-sill charge once you're past ten windows
Track and sill detailing is billed at roughly $5–$10 per window or a flat charge near $75, so the flat option wins on anything over about ten windows. Ask which method your quote used before you sign.
Aim sprinkler heads away from the glass
Hard-water and mineral-stain removal is a restoration add-on at about $40 per affected pane, and it is a different line item from routine track cleaning. Keeping irrigation off the windows through Kent's March-to-November growing season avoids it entirely.

Local Regulations & HOA Notes for Kent Window Cleaning
Three Kent and Washington specifics worth knowing before you book:
- Kent's noise rules — KCC 8.05.110: "KCC" here is the Kent City Code, a City of Kent municipal ordinance, not King County Code. Chapter 8.05 sets maximum permissible noise levels by EDNA zone, and KCC 8.05.110 then exempts residential upkeep from those decibel limits during fixed daytime hours: "Sounds originating from residential property related to temporary projects for the maintenance or repair of homes, grounds and appurtenances are exempt from the maximum permissible noise levels during the hours of 7:00 a.m. to 10:00 p.m." Both pieces apply together — the decibel limits are the standard, and the 7:00 AM – 10:00 PM window is the exemption from them, identical on weekdays, Saturdays and Sundays. Window cleaning is near-silent, so it rarely matters either way, but a water-fed-pole pump or a generator is easiest to schedule inside those hours.
- Sales tax on the invoice — 10.40% in Kent: Washington treats residential window cleaning as a taxable retail service. Kent's combined rate is 10.40% as of 2026 Q2, and it applies to the entire invoice — screens, track detailing and mineral-stain removal included. On the illustrative $384.00 pre-tax example above that is $39.94. Kent sits inside the Sound Transit RTA taxing district, so the regional transit portion is already baked into that 10.40%; a quote showing a noticeably lower rate is worth questioning.
- Water-fed poles and wash water: Crews working Kent's two-story homes often rinse with purified water through a water-fed pole and no detergent, so a standard residential clean raises no storm-drain or wash-water permitting question. If a crew proposes a chemical hard-water restoration on ground-floor glass, ask how the runoff is contained before it reaches the street.

Kent Window Cleaning Calendar
What to expect month-by-month for window cleaning in the Kent, WA climate.
| Month | Recommended Activity |
|---|---|
| January | Short grey days show every streak, so interior-only cleans are easy to book and are priced per pane like any other visit. |
| February | Reserve the spring visit now — March through May fills first on South King County crews' calendars. |
| March | Kent's growing season opens in March and the last spring frost lands around March 2, so exterior work becomes comfortable mid-month. |
| April | Fir and grass pollen start coating south- and west-facing panes across the city. |
| May | Peak season for the once-a-year both-sides clean at roughly $18–$24 a pane. |
| June | Long daylight makes this the practical month for skylights ($25–$45 each) and upper-story work on two-story homes. |
| July | Dry weeks mean sprinkler overspray, the main cause of the mineral spotting that costs about $40 per affected pane to reverse. |
| August | Valley dust and late pollen make an exterior-only touch-up worth the $10–$14 a pane between full cleans. |
| September | The best month to book the fall visit — get the glass clean before the wet season sets in. |
| October | Leaf debris packs window tracks, which is when the flat $75 track-and-sill charge earns its keep. |
| November | The growing season closes and the first fall frost arrives around November 23, in the wettest stretch of the roughly 39 inches of rain Kent gets each year — push remaining work indoors to interior glass and screens. |
| December | Slower scheduling and holiday light installs make it worth cleaning the exterior glass before decorations go up. |
What Affects Window Cleaning Cost in Kent?
Cleaning scope — exterior, interior, or both sides
The first question every quote asks. Exterior-only runs about $10–$14 a pane and both sides about $18–$24 a pane, roughly 1.5–1.7× an exterior-only clean of the same home.
Pane count
Pane count is the dominant volume driver, because the job is quoted per pane rather than per hour or per square foot. Counting your own panes before calling is the fastest route to an accurate phone number.
Story and height access
Upper-story panes add roughly $3–$6.50 each, and two- to three-story homes add about 25–55% to base labor for ladder or water-fed-pole work. If your home has a second story, this is the single most common reason a quote lands above the regional midpoint.
Window type and complexity
Not all glass prices the same: skylights run $25–$45, bay and picture windows $15–$25, French doors $20–$40 per side, and sliders $15–$30. A home with a lot of specialty glass quotes well above a plain pane count.
Add-ons — screens, tracks and sills, mineral stains
Screens run about $2–$5.50 each. Track and sill detailing is about $5–$10 per window or a flat charge near $75, while hard-water or mineral-stain removal is a separate restoration line at about $40 per affected pane — the two are not interchangeable.
Buildup level and the minimum charge
A home skipped for one to two years takes extra labor to cut stubborn Pacific Northwest buildup, and small jobs are floored at a $100–$175 minimum service charge in this market. Regular visits keep you at the low end of both.
