Window Cleaning Services in California
Window cleaning in California removes the hard-water spots, dust, salt film and gritty tracks that cloud glass. Fast Pro washes by hand, never with pressure, gives you a free quote first, and walks the job with you before we leave.
California window problems, and what causes them
Hard water, dust and coastal air build up on glass faster than most people expect. Here are the six problems we get called about most.
Sprinkler hard-water spots
Mineral-rich water dries into white spots on glass. Los Angeles' utility reports hard water, at about 300 mg/L as calcium carbonate at some supply plants. GT Glass says deposits are harder to remove the longer they sit.
Dust and smoke film
Dry winds and wildfire smoke leave a gritty film on glass. After heavy ash, the EPA says to avoid dry wiping and never use a leaf blower, and to use as little water as you can.
Stucco and construction dust
Viracon, a glass maker, says concrete and mortar slurry is highly alkaline and can eventually etch glass, so it needs to be washed off quickly.
Cloudy glass that will not clear
If the haze stays after the glass is clean and dry, it is usually etching. GT Glass says etching is damage in the glass, not a deposit, so harsher scrubbing will not remove it.
Dirty screens
Screens collect dust and pollen. Milgard says mild soap, water and a soft brush clean them.
Gritty tracks and weep holes
Grit packs the tracks and sills, and it slows the window. Milgard says its weep system needs regular cleaning so water can drain.
Every part of a California window
Hand washed, never pressure washed.
Exterior glass
Washed by hand and dried, out of direct sun so it does not streak.
Frames and sills
Wiped down by hand, which also keeps dirt from running back onto clean glass.
Tracks and weep holes
Grit and debris cleared by hand so windows slide and drain properly.
Window screens
Washed with mild soap, water and a soft brush, then dried before they go back.
Low-E and coated glass
Cleaned to the maker's guide. No razor blades or metal tools touch the coated surface.
Filmed and tinted windows
We ask first. Film makers say to wait 30 days after install, then use a soft cloth and no ammonia.
Window cleaning built around California water, dust and glass
California windows get hit from several directions. Hard sprinkler water leaves mineral spots, dry winds and smoke leave a film, and coastal homes collect fog residue. Many modern homes also have coated glass or film, and each one has its own cleaning rules.
Our rule is to use the gentlest method that gets the glass clean. We wash by hand, we never aim pressure at glass or seals, and we do not use razor blades on coated glass. Milgard, Pilkington, PGT, Andersen and Viracon all advise against razors and metal tools on glass.
Hard-water spots are the honest limit. We can remove many fresh spots, but etched glass will not come clean, and fog between the panes means a failed seal that cleaning cannot fix. We will tell you which one you have before we quote.
Hard water
LADWP's 2015 report lists some supply plants near 300 mg/L as calcium carbonate. Spots return until the spray is redirected.
Coated glass
Pilkington says no razor blades or steel wool on the coated surface, and prefers no squeegee on it.
Seal failure
Milgard says moisture or etching between the panes is seal failure that cannot be cleaned.
Wildfire ash
The EPA says never dry-wipe ash or use a leaf blower, and to keep ash out of storm drains.

What window cleaning can and cannot fix
Cleaning removes dirt and fresh mineral spots. A few problems need more than cleaning.
Cleaning will help
- Dust, smoke and dirt film
- Fresh sprinkler spots
- Gritty tracks and sills
- Dirty screens
Needs more than cleaning
- Etched or pitted glass
- Fog between double panes, which means a failed seal
- Scratches already in the glass
- Film that is peeling or bubbling
We will tell you which list your windows are on before we quote. Call us and describe it.
What goes into a California window cleaning quote
We quote every job by phone, because a one-story ranch and a three-story townhome are different jobs. These are the factors we weigh.
Number of windows
The count and the size of the panes set the base price.
Stories and access
Upper floors and tight access take more time and equipment.
Buildup
Years of dust and mineral spots take more time than a regular wash.
Screens and tracks
Tell us if you want screens and tracks cleaned too.

Call 813-536-7337Scheduling and coverage
Do you serve all of California?
We work across the state, including the Bay Area, Los Angeles, Orange County, the Inland Empire, San Diego, the Central Coast and the Sacramento and San Joaquin valleys. Call with your address and we will confirm coverage and the soonest opening.
How soon can you come out?
Call early in the day and we will give you the soonest slot we have. We will tell you plainly if the schedule is full.
What happens if it rains?
Light rain does not stop an exterior job. Storms and high wind do. We reschedule at no charge and let you know the same day.
Do I need to be home?
No, as long as we can reach the exterior and an outdoor spigot. Please close windows, move cars and bring in small items.
Methods and safety
Do you use razor blades on my windows?
No. Milgard, Pilkington, PGT, Andersen and Viracon all advise against razors and metal tools on window glass, and metal contact can leave marks that normal cleaning cannot remove.
Is it safe to pressure wash windows?
No. Milgard says high-pressure hoses may damage the glass, frame or insulating seal, and PGT and Andersen also say not to pressure wash windows. We wash glass by hand.
Can you clean windows after wildfire ash?
Light dust, yes. For heavy ash, the EPA says to avoid dry wiping, never use a leaf blower, use as little water as you can, and keep ash out of storm drains. Call us first and we will tell you how we would handle it.
Can you remove sprinkler hard-water spots?
Often, if they are fresh. If the glass stays cloudy after it is clean and dry, it is usually etching, and GT Glass says harsher scrubbing will not remove it. We will tell you which one you have.
Pricing, insurance and water rules
How often should I clean my windows in California?
Window makers suggest at least yearly, and PGT gives yearly as its baseline. Hard sprinkler water, dust and coastal air mean many California homes need more. We will tell you what we see.
Why do my windows get dirty so fast?
Sprinkler overspray, dust, smoke and coastal fog all leave film, and hard water leaves mineral spots that bake on in summer heat. Spots are easier to remove when they are fresh.
How much does window cleaning cost in California?
It depends on size, material, how much growth or buildup there is and how easy the site is to reach. Call for a free quote and we will explain which of those drive your price.
Do California water and runoff rules affect the job?
Wash water is the bigger rule. Cities and counties across California say wash water must not reach the street or storm drain, and we keep it out and follow local stormwater rules. Water-use rules also vary by city and supplier, so we check yours before we book and tell you if a job has to wait.
Are you licensed and insured?
Yes. Fast Pro Pressure Washing is licensed and insured. Ask for proof of insurance with your quote and we will send it.
Do you guarantee the work?
Yes. If something does not look right after the job, contact us and we come back to fix it at no charge.
