Overview: Window Cleaners
Window cleaning is bought by the visit and judged from inside on the first sunny morning afterwards. Most crews do inside and outside glass, the frames, the sills and the tracks, and screens washed rather than knocked out and leaned against a wall. Skylights, solar panels and gutters are usually priced separately.
There are two ways to do the outside. A squeegee with detergent and a cloth, applied by somebody at the glass on a ladder, which is fast and precise. Or a water-fed pole, which sends purified water up a long brush from the ground: nothing to dry, no detergent, and the glass dries clear because the minerals that leave spots have been filtered out of the water. Pole work reaches upper floors without a ladder in your flower bed or hooked over the roof edge.
How often depends on exposure. A house on a busy road, under sprinklers, near salt air or beside construction dirties far faster than one on a quiet street. The first visit takes longer than the ones after it, because years of buildup come off once.
Listings show what each company states on its own website: what a clean covers, its hours, and what customers report publicly. The state and city lists below narrow it down.
Cost of Window Cleaning
Count the glass panes and specify which sides will be cleaned. A standard double-hung window usually has two visible panes; insulated double-pane glass does not mean two separately cleanable windows. Ask for the total after the visit minimum and any screen or track work.
| Service or scope | Planning range | What this covers |
|---|---|---|
| Exterior glass cleaning | $4.50–$7per ordinary glass pane, exterior only | Clean the accessible outside surface of one ordinary-size glass pane during a routine residential visit.A double-hung window generally has two cleanable panes. Ask how the cleaner counts your window styles and applies the minimum charge.Included scope and possible extrasScope used for this estimate: Exterior glass cleaning; Basic edge or sill wipe where listed Outside this estimate: Visit minimum if not met; Screen washing and deep tracks unless listed; Storm or divided-light assemblies; Heavy mineral or construction residue |
| Interior and exterior glass cleaning | $7–$12per ordinary glass pane, both sides | Clean the inside and outside surfaces of one ordinary-size glass pane with normal interior and exterior access.Check whether screens and detailed tracks are included. Ask about ladders, furniture access and any extra charge for neglected glass.Included scope and possible extrasScope used for this estimate: Interior and exterior glass cleaning; Basic wipe stated in the package Outside this estimate: Visit minimum if not met; Separately quoted screen washing and deep tracks; Storm or divided-light assemblies; Heavy mineral or construction residue |
| Screen washing | $2–$6per screen added to a cleaning visit | Wash serviceable standard insect screens as an add-on to an existing window-cleaning visit, with removal and replacement agreed.Do not add this charge if screen washing is already in the package. Screen repair and heavy solar screens need separate prices.Included scope and possible extrasScope used for this estimate: Removal; Washing; Reinstallation Outside this estimate: Screen repairs; New mesh; Storm-window assemblies |
| Deep track cleaning | $1–$7per standard window track set | Detail-clean accessible tracks and sills during an existing window-cleaning visit; specify the window type and buildup.Distinguish a quick sill wipe from vacuuming and scrubbing tracks. Adhesive, paint and severe buildup need inspection.Included scope and possible extrasScope used for this estimate: Track cleaning; Debris removal Outside this estimate: Hardware repair; Paint removal; Mold remediation |
Example budget
Illustration for 20 ordinary double-hung windows: $280–$480 for glass on both sides
20 windows with 2 cleanable panes each, ordinary access; screen washing and detailed tracks are added only if not bundled.
20 windows × 2 panes × $7–$12. Confirm the visit minimum and exact pane count.
What changes the price
- Number and type of cleanable glass panes, and one side versus both sides
- Height, ladder access, furniture and condition of glass
- Minimum visit charge and whether screens or deep tracks are included
Ask before you book
- How are panes counted, and does this total cover the outside only or both sides?Per-pane and per-window rates can describe different amounts of glass.
- What is the total after minimum charges, access fees, screens and track work?A low unit rate may not be the amount you pay, and bundled work should not be charged twice.
- Are mineral stains, paint or construction residue included after inspection?Routine glass washing and restoration require different work and pricing.
Check the scope
These are routine residential cleaning rates. Confirm the whole visit price; storm windows, divided lights, high access and construction residue require a specific scope.
Compare quotes wisely
Combine inside and outside cleaning in one visit and request optional screen or track detailing as separate line items.

Frequently asked questions
Water-fed pole or traditional squeegee?
Pure water through a pole is safer and better on upper floors, since nobody is standing on a ladder over a driveway, and it cleans the frames at the same time. A squeegee gives a sharper finish on reachable glass and a skilled cleaner is very fast with one. Many crews carry both. What matters more is whether they detail the edges and the sills instead of leaving drips.
How often do windows actually need cleaning?
Exposure decides it, not a calendar. Glass facing a busy road, a lawn sprinkler, salt air or a construction site needs attention several times a year. A sheltered back elevation can go far longer. Watch for the point where dirt stops rinsing off in rain and starts staying, because that is when mineral deposits begin to bond to the glass and the job gets harder.
Are screens, sills and tracks part of the price?
Put the question to them, since this is the line that separates two otherwise similar prices. A thorough visit takes screens out, washes them, and cleans the tracks and sills before the glass goes back to looking new. A cheap visit does the glass and leaves a dirty frame that drips onto it in the next rain. Get the inclusions written down, and mention any window that has not been opened in years.
Why will some marks not come off the glass?
Because they are in the glass rather than on it. Sprinkler spray, runoff from concrete and years of hard water leave mineral deposits that eventually etch the surface, and no detergent or pure water rinse reverses that. The repair is mechanical polishing by a glass specialist, or a new pane. The same goes for scratches from a previous scraper and for fine pitting from stucco or masonry work.
Who does the glass on tall buildings?
A different trade. Anything above the reach of a pole or a short ladder means rope access or a suspended platform, and those crews carry specific training, rigging inspections and insurance that a residential window cleaner does not. If a company offers to free climb a balcony rail or lean a ladder off a roof, that is the moment to say no.
