House Washing Services in California
House washing in California removes the green algae, black mildew, dust film and mineral spots that fog, sprinklers and dry winds leave on stucco, siding, brick and wood. Fast Pro uses a low-pressure soft wash, keeps wash water out of the storm drain, gives you a free quote first, and walks the job with you before we leave.
California exterior wall problems, and what causes them
Damp coastal air, dry inland dust and hard sprinkler water all leave marks on a California house. Here are the six problems we get called about most.
Green film on shaded walls
Algae shows up first on shaded and north-facing walls, where the sun does not dry the surface. Sto, a stucco finish maker, says green growth is algae and black is mildew. A soft wash treats both at the root.
Black mildew on stucco
Porous stucco holds moisture, so mildew settles in. Sto caps pressure at 500 psi on its acrylic finishes, because higher pressure can destroy the finish.
Mineral and rust spots
Hard or iron-rich sprinkler water leaves white and orange spots on any wall the spray touches. They need a different cleaner than algae does.
White haze on stucco and brick
That powder is usually efflorescence, salt left behind as moisture moves through the wall. The Brick Industry Association says to find the moisture source, because cleaning alone will not stop it.
Dust, smoke and ash film
Dry winds and wildfire smoke leave a gritty film on walls and trim. After heavy ash, county health agencies say to wet-wipe gently, use little water, and never use a leaf blower.
Dirt splash and webs
Rain and sprinklers splash soil onto the bottom of walls, and webs collect under eaves and lights. We rinse and clear them as part of the wash.
Every wall material on a California house
One soft wash method, adjusted for each material.
Stucco
Low pressure, since high pressure can chip paint and destroy the finish. Older cement stucco gets a test spot first.
Fiber cement siding
Soft wash, following the siding maker's published limits for pressure and distance.
Redwood and cedar siding
Soft approach and mild detergent, with no wire brushes. We test a spot before the full wash.
Brick and stone veneer
Soft wash with low pressure and no acid. High pressure erodes mortar joints, so we test first.
Vinyl siding
A gentle wash and a careful rinse, so water is not pushed up behind the laps.
Painted trim, soffits and fascia
Low pressure and a test spot first, since loose paint can come off with the dirt.
House washing built around California walls and California rules
Stucco is common on California homes, and it is porous, painted and easy to damage. Redwood and cedar siding want a soft approach, and fiber cement has its own limits. So we pick the method wall by wall instead of using one setting for the whole house.
Our rule is to use the gentlest method that gets the wall clean. The cleaning solution does the work and the rinse stays gentle. That protects your paint, seals and caulk, and it lasts longer than scrubbing at growth with a nozzle.
Wash water is the other California difference. San Diego, Sacramento County and other agencies say it must not reach the storm drain. We plan each job around that, and we use cleaners suited to the surface.
Stucco limits
Sto says not to exceed 500 psi on its acrylic finishes, and to keep the nozzle several feet away.
Redwood and cedar
The California Redwood Association says to use a hose, soft approach and mild detergent, and to avoid wire brushes.
Storm drain rules
San Diego says wash water must be contained and captured. Sacramento County says the same.
Wildfire ash
County health agencies say to use little water and keep ash out of storm drains.

What goes into a California house washing quote
We quote every job by phone, because a lightly dirty ranch and a mildewed two-story are different jobs. These are the factors we weigh.
Size and stories
Square footage and the number of stories set the base price.
Wall material
Stucco, wood and stone take more care than smooth vinyl.
How much growth
Light dirt is a short job. Years of mildew take more time and solution.
Access and runoff control
Slopes, tight side yards and nearby storm drains change the setup time.

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
Is house washing the same as pressure washing?
No. House washing is a soft wash. A cleaning solution and a gentle rinse do the work, and pressure stays low. Pressure washing uses force and suits concrete.
Will it damage my stucco?
It should not. We keep pressure low. Sto says not to exceed 500 psi on its acrylic finishes, because the finish can be destroyed at higher pressure, and to keep the nozzle several feet away. We test a spot first.
Can you wash redwood or cedar siding?
Yes, gently. The California Redwood Association says to use a hose, a stiff bristle brush for stubborn grime, and mild detergent, and to avoid wire brushes and steel wool. We test a spot before the full wash.
Is it safe for my plants and pets?
We wet plants before and after, keep solution strength as low as the job allows, and tell you when it is safe for pets to go back out.
Pricing, insurance and water rules
Should I wash before I paint?
Yes. Sherwin-Williams says to rinse the surface thoroughly and let it dry before painting. Tell us your painter's date and we will plan around it.
Can you wash my house after wildfire smoke?
For light dust and smoke film, yes. For heavy ash, county health agencies say to wet-wipe gently, use as little water as possible, avoid leaf blowers, wear an N95 or P100 respirator and keep ash out of storm drains. Call us first and we will tell you how we would handle it.
How much does house washing 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.
