Most homes in Ventura County pay between $150 and $475 for a complete residential window cleaning. The band is wide because the price tracks your window count, your home’s height, and how much mineral buildup is already on the glass, not a flat per-window rate. Aloha Window Bros quotes $150 to $400 in Thousand Oaks, $175 to $425 across most of the Conejo Valley and the city of Ventura, and $200 to $475 in Ojai and Santa Barbara. Every estimate below is our own published pricing, given free and on site, usually within 24 hours.
Key Takeaways
- Typical Ventura County range: $150 to $475 for a complete residential job (exterior glass, interior glass, screens, frames, and sills).
- Biggest price driver: window count and second-story access, not square footage.
- Coastal and well-water cities cost more because salt and mineral load take longer to remove properly.
- Hard water restoration is priced separately at $200 to $500, because it is a different job from cleaning.
- A per-window quote under $8 usually means screens, frames, and sills are not included. Ask before comparing.
What Window Cleaning Costs in Each Ventura County City
Almost every article on this topic quotes a national average and stops there. A national average is close to useless here: Ventura County contains both imported water at the soft end and well water at the hard end, plus a coastline that puts salt on glass in Oxnard that never reaches Simi Valley. Those conditions change how long a job takes, and time is what you are paying for. These are our published bands, by city:
| City | Typical full-home range | Why it sits here |
|---|---|---|
| Thousand Oaks | $150 to $400 | Our home base, shortest drive time, mostly imported water |
| Agoura Hills | $175 to $425 | Canyon dust, many corner lots with heavy sprinkler overspray |
| Newbury Park | $175 to $425 | Canyon dust plus a damp-then-dry cycle that cements dust in place |
| Westlake Village | $175 to $425 | Larger two-story homes with high window counts |
| Camarillo | $175 to $425 | Agricultural dust, Camrosa water on the harder end |
| Simi Valley | $175 to $425 | Dry heat bakes dust into glass, little marine moisture to soften it |
| Ventura | $175 to $425 | Coastal salt plus private wells in older Midtown and east Ventura |
| Oxnard | $175 to $450 | Coastal salt and agricultural dust together |
| Ojai | $200 to $475 | The hardest water in the county, roughly 17 grains per gallon |
| Santa Barbara | $200 to $475 | Larger homes, longer drive time, sustained salt exposure |
“Aloha Window Bros publishes a per city price band for all ten cities it serves in Ventura and Santa Barbara counties, ranging from $150 to $400 in Thousand Oaks to $200 to $475 in Ojai and Santa Barbara. The spread is driven by water hardness, salt exposure, and home size rather than by a flat per-window rate.”
What Actually Changes Your Price
Four variables move a quote inside those bands. In our experience they matter in roughly this order:
| Factor | Effect on price | Why |
|---|---|---|
| Window count | Largest | Each pane is a fixed unit of labor, inside and out |
| Number of stories | Large | Upper-story glass needs water-fed pole work or ladder setup |
| Mineral and salt buildup | Moderate | Etched or scaled glass takes several passes, not one |
| Accessibility | Moderate | Landscaping, steep lots, and fixed screens all add time |
Square footage is a poor predictor on its own. A 2,400 square foot ranch home with 18 windows costs less to clean than a 2,000 square foot two-story with 34 windows and a wall of glass facing the canyon. This is why we quote on site rather than over the phone: we are counting panes and looking at the glass, not looking up your home on a listing site.
Why Hard Water Cities Cost More
Water hardness is measured in grains per gallon (gpg). The U.S. Geological Survey classifies water above 180 mg/L of calcium carbonate, roughly 10.5 gpg, as very hard.
The difference across our service area is bigger than most homeowners expect. According to the Ventura County Public Works Agency, Ojai water averages about 17 grains per gallon, drawn from wells in the Ojai Valley Groundwater Basin. Westlake Village, by contrast, is served entirely with imported water that both of its utilities report at 146 mg/L of calcium carbonate, about 8.5 gpg. Ojai homeowners are cleaning up after roughly double the mineral load of Westlake Village homeowners, which is the single clearest reason the Ojai band sits $50 higher at each end.
If your glass already has visible cloudiness rather than spots, you are likely past cleaning and into restoration. That is a separate service at $200 to $500, because it involves polishing the mineral deposit out of the glass surface rather than washing something off it. Our guide to removing hard water stains from windows explains how to tell the difference before you pay for the wrong service.
What “Window Cleaning” Should Include
Price comparisons in this trade break down because two companies quoting “window cleaning” are often quoting different jobs. Every Aloha Window Bros quote is a four-in-one clean:
- Exterior glass, finished with purified water so dissolved minerals cannot re-spot as it dries.
- Interior glass, including sills and interior tracks.
- Screens, washed rather than brushed off, because a dirty screen makes clean glass look dirty within days.
- Frames and sills, wiped down so debris does not wash back onto the glass in the first rain.
That last point is where most low quotes hide. A $6 per window price that covers exterior glass only is not cheaper than a $10 per window price that covers all four, it is a different product. Our screen cleaning guide covers why screens in particular are the piece homeowners most often discover was excluded.
Annual Cost Beats Job Cost
Letting glass go a full year is usually a false economy here. Mineral deposits and salt both etch progressively, so once etching starts the fix moves from a $175 cleaning to a $200 to $500 restoration. Most Ventura County homes do well every three to four months; quarterly suits hillside homes in Santa Ana wind corridors and coastal homes taking direct salt spray. Regular service is priced at the low end of a band. Neglected glass is priced at the high end of the next band up.
How to Compare Quotes Fairly
Ask every company you call these four questions:
- Does the price include screens, frames, and sills, or exterior glass only?
- Do you use purified water on the final pass, or tap water?
- Are you insured, and can you send proof?
- Is the quote firm after an on-site look, or an estimate that changes on the day?
The purified water question matters more here than in most markets. Washing Ventura County glass with local tap water and letting it air dry deposits the same minerals you just paid to remove, which is why a cheap job can look worse than no job two weeks later.
Frequently Asked Questions
How much does window cleaning cost in Ventura County?
Most Ventura County homes pay between $150 and $475 for a complete residential window cleaning that includes exterior glass, interior glass, screens, frames, and sills. Aloha Window Bros quotes $150 to $400 in Thousand Oaks, $175 to $425 across most of the Conejo Valley and Ventura, $175 to $450 in Oxnard, and $200 to $475 in Ojai and Santa Barbara. Estimates are free and given on site.
Why is window cleaning more expensive in Ojai and Santa Barbara?
Ojai runs on local well water averaging about 17 grains per gallon, roughly double the mineral load of the imported water serving the Conejo Valley, so removing deposits takes more passes. Santa Barbara homes are typically larger, sit under sustained coastal salt exposure, and involve longer drive time. Both factors are time, and time is what the price reflects.
Is window cleaning priced per window or as a flat rate?
Aloha Window Bros quotes a flat rate for the whole job after an on-site count. Per-window pricing sounds transparent but hides the variables that actually matter: story height, screen condition, and existing mineral buildup. A firm flat quote after someone has looked at your glass is the only number that will not move on the day.
Does the price include screen cleaning?
Yes. Every Aloha Window Bros job is a four-in-one clean covering exterior glass, interior glass, screens, and frames and sills. Many quotes in this market cover exterior glass only, which is the most common reason two prices for “window cleaning” are not comparable.
What does hard water stain removal cost?
Hard water restoration runs $200 to $500, separate from a standard cleaning at $150 to $475. It is a different job: cleaning removes deposits sitting on the glass, restoration polishes deposits that have already etched into the glass surface. If your windows look cloudy rather than spotted, you likely need restoration.
How often should windows be cleaned in Ventura County?
Every three to four months suits most homes. Quarterly is better for hillside homes in Santa Ana wind corridors and coastal homes taking direct salt spray. Shaded homes with low exposure can stretch to six months. Going a full year usually costs more overall, because progressive etching moves the job from a cleaning to a restoration.
