How Much Does Window Cleaning Cost? (2026 Guide)
As of 2026, national data puts window cleaning at $10 to $18 per window, or $150 to $900 for a full-home visit depending on how many windows you have. The two biggest price drivers are window count and number of stories. Supreme Gutter Services gives every Largo home a free phone quote instead of a flat price.
How much does window cleaning cost in 2026?
National pricing data from Housecall Pro puts window cleaning at $10 to $18 per window in 2026. For a full job, that breaks down into rough size-based ranges:
| Home size | Typical range |
|---|---|
| Small (10-15 windows) | $150 to $275 |
| Medium (20-25 windows) | $250 to $450 |
| Large (30+ windows) | $450 to $900 |
A national chart cannot see your windows. It cannot count them or check how much buildup has to come off first. That is why Supreme Gutter Services does not publish a flat local price list. Every home gets priced on its own window count, its own access, and its own buildup. Call for your free phone quote, and get a real number instead of a national guess.
What makes the price go up or down?
A few things move the price more than anything else.
Window count and number of stories. More windows means more time. That part is simple. Stories matter less with Supreme than with most crews. The water-fed pole system reaches second-story glass from the ground. There is no ladder setup time. There are no ladder safety checks between windows.
Inside and outside, or just outside. A full inside-and-out clean costs more than an exterior-only visit. The interior is cleaned by hand with a squeegee, which takes more time than the pole system alone.
Screens, tracks, and sills. Cleaning the screens and wiping down the tracks and sills adds a little time. It also keeps the whole window clean, not just the glass in the middle.
How much buildup has to come off. Hard-water mineral spots and a heavy pollen film take more work to strip than light dust. That buildup is a real factor for Largo homes. The next two sections explain why.
Why does hard water leave spots on Largo windows?
Largo's tap water is hard. Local water-quality reporting puts it at 210 mg/L, about 12.3 grains per gallon. Hard water carries dissolved minerals. Those minerals stay behind on glass as the water dries. That is what causes the cloudy spots and streaks you see on windows washed with a garden hose or plain tap water.
That is why Supreme Gutter Services finishes every job with deionized water instead. Deionized water has those minerals stripped out. It dries clean, without leaving anything behind. Think of the spot-free rinse at a car wash. It works the same way, just applied to your windows. That is the fix for Largo's hard-water spotting. A different cleaner will not solve it. A different rinse water does.
How often do Tampa Bay homes need window cleaning?
Oak and pine trees drive tree pollen across the Tampa Bay area. That season runs from December through May, one of the longest pollen seasons in the country. Windows here pick up a pollen film for roughly half the year, not just a short spring stretch like homes further north. A single spring cleaning does not cover a season that long.
Largo's housing stock adds to the picture. The median home was built in 1978. About 56 percent of the city's homes predate 1980. Older aluminum frames pit and wear over time. Rough, worn frames give hard-water spots and pollen film more to cling to. Between the long pollen season and the older frames, most homes here hold up better on a regular cleaning schedule than a once-a-year one.
What is included in a professional window cleaning?
Supreme Gutter Services cleans the outside of your windows with purified, mineral-free water on a long pole. That water comes from a reverse osmosis and deionized water system, so the pole reaches upstairs windows from the ground. That means no ladder leaning against your house. It also means no chemicals running down your siding or into your landscaping. The inside gets cleaned by hand with a professional squeegee. Screens, tracks, and sills are wiped down too, so the whole window comes out clean, not just the glass in the middle.
A professional window cleaning covers both sides of the job. The outside gets a chemical-free wash. The inside is cleaned by hand. That is what Supreme Gutter Services does on every visit, built around the local hard water and the long pollen season, not a generic routine borrowed from a drier climate.
Supreme Gutter Services also runs a gutter cleaning service, so you can book both jobs in one visit instead of two. If you want to plan for both costs at once, the gutter cleaning cost guide breaks down what that side of the job runs.
A national chart still cannot see your windows. Talk to Supreme Gutter Services and find out what your windows actually need.

FAQ
Related questions
Are professional window cleaners worth it?
For most Largo homeowners, yes. Second-story windows mean climbing a ladder, and ladder falls are one of the most common home injuries. Supreme's water-fed pole system cleans second-story glass from the ground, so there is no ladder against the house. The deionized water finish also solves Largo's hard-water spotting in a way a garden hose and a squeegee cannot.
How long does a window cleaning visit take?
It depends on how many windows you have and whether you want inside and outside done, or just the outside. More windows and a full inside-and-out clean take longer than a quick exterior-only visit. Supreme Gutter Services gives you a time estimate with your free phone quote, so you know before the crew shows up.
Can you bundle window cleaning with a gutter cleaning visit?
Yes. Supreme Gutter Services runs both gutter cleaning and window cleaning as regular services, so you can schedule both on the same visit instead of booking two different companies. Ask about combining them when you call for your quote.
