House Washing in Jacksonville, FL
If the north side of your house has turned dark green, or the soffits under your roofline look like someone painted them gray, that is algae and mildew doing what they always do in Northeast Florida. House washing in Jacksonville is not about blasting the dirt off. It is about knowing what is growing on your siding, choosing the right low-pressure soft wash, and making sure water does not get pushed into places it should never go.
- Soft wash only on sidingLow pressure that cleans without forcing water behind panels
- Kills algae at the rootNot just rinse it off so it comes back in three weeks
- Plants protected before we startWe wet and shield landscaping every time

Why does my Jacksonville house keep turning green?
Walk any neighborhood in Mandarin, Ortega or Riverside on a humid morning and you will see it on every other house. The north-facing walls, the spots under the big live oaks, the areas where a sprinkler clips the siding. That dark green or black film is not road grime. It is a living thing, mostly algae and mildew, and it thrives here because Jacksonville gives it everything it needs.
We get heavy rain from June through September. The air stays humid nearly year-round. Mature tree canopies in Avondale, San Marco and Fleming Island keep walls shaded and damp for hours after it rains. Add pine pollen in spring and salt air if you are anywhere near Jacksonville Beach, Atlantic Beach or Neptune Beach, and your exterior has a hard time staying clean. That is just North Florida.
The question is not whether it will come back. It will. The question is what method removes it safely and how long the clean lasts.
- North and west walls stay shaded longest and show growth first
- Under eaves and soffits where moisture collects after rain
- Near irrigation heads that clip the siding and keep it wet
- Around windows and doors where caulk traps moisture
- Coastal homes near Jax Beach and Neptune Beach get salt on top of algae
Soft washing vs pressure washing: what is right for house siding?
This matters more than most people realize. High pressure on vinyl siding, stucco, painted wood or brick can force water behind the panels, crack old mortar, strip paint and break caulk seals around windows. That water sits in the wall and causes damage you do not find until it is expensive to fix.
The right method for house washing in Jacksonville is a soft wash. That means low pressure combined with a cleaning solution that kills the algae and mildew at the root. We apply it, let it dwell, and rinse gently from the top down. The growth dies and washes away instead of just getting pushed somewhere else.
| Siding type | Method | What we watch for |
|---|---|---|
| Vinyl siding | Soft wash, top to bottom rinse | Water forcing behind joints and edges |
| Stucco smooth or textured | Very low pressure with cleaning solution | Hairline cracks that let water into the wall |
| Brick | Gentle soft wash | Old mortar that can erode |
| Painted wood or HardiePlank | Soft wash only, no pressure | Peeling paint that needs repair before washing |
| EIFS synthetic stucco | Soft wash, careful at seams | Delamination near seams if pressure is used |
| Soffits and fascia | Gentle rinse | Dirt running back onto clean walls |
If your siding has cracks, loose caulk or a window that already leaks, tell us before we start. Washing does not fix those. We will flag them and let you decide.
What does a house washing visit include?
Homeowners ask this a lot. Here is what the job looks like start to finish.
- Walk-around first. We check the siding, note cracks, look at windows and doors for loose caulk, and flag anything that might be a problem before water gets near it.
- Protect plants and outlets. Landscaping gets wetted down before we apply any cleaner. Outdoor outlets, lights and HVAC units get covered or avoided.
- Apply the soft wash solution. We wet the siding and apply a mix that targets algae and mildew. It needs a few minutes to work. Rushing this step means faster regrowth.
- Rinse from the top down. Starting at the roofline and working down means dirty water does not run over clean surfaces below.
- Soffits, fascia and the entryway. These are the spots many companies skip. We include them because they are usually the dirtiest.
- Walk-through with you. We go around together when we finish. If something did not respond the way we expected, we say so. Rust from irrigation or old stains near the garage may need separate treatment and we will tell you that before we leave.
How long does house washing in Jacksonville actually last?
Honest answer: it depends on your lot. A house on a shaded, north-facing lot in Mandarin with live oaks close to the walls and sprinklers that clip the siding might show growth again in 12 to 18 months. A house in Nocatee or Ponte Vedra on an open sunny lot with well-managed irrigation might stay clean for two to three years.
Most Jacksonville homeowners wash once a year or once every other year. Some do it before listing a home for sale. Some do it after storm season when leaves and mildew have piled up. Some do it because the HOA sent a letter. All of those are reasonable triggers.
- Shade from live oaks, magnolias or tall privacy hedges speeds regrowth
- Sprinklers hitting the siding keep it wet and feed the algae
- Proximity to water like the St. Johns River, a pond or the Intracoastal
- Salt air at Jacksonville Beach, Atlantic Beach and Neptune Beach
- A roof with algae that sheds spores down onto the walls
We will give you an honest read on your property during the quote. If it is a house that stays clean, we say so. If it needs washing every year, we say that too.

FAQ
House Washing Questions Jacksonville Homeowners Ask
Is soft washing safe for vinyl siding?
Yes, and it is what vinyl siding manufacturers actually recommend. High pressure forces water behind the panels and into the wall. Soft washing cleans at low pressure with a solution that kills the algae so it does not come straight back.
Will it remove all the green from my siding?
Most of it, yes. Dense algae on vinyl and brick comes off cleanly. Stains that have worked into old or porous paint may lighten rather than disappear completely. We tell you what to expect before we start, not after.
How long does a house wash take?
A single-story home usually takes two to three hours. A large two-story with heavy growth takes longer. We give a time estimate with the quote.
Do I need to be home when you wash the house?
Not always. We need access to the yard, an outdoor water tap and any gated areas. If you are at work, we sort out access ahead of time and send photos when we finish.
Will the cleaning solution hurt my plants?
It can if not handled properly. We wet plants down before applying any cleaner and direct rinse water away from beds. Point out anything delicate when you request the quote.
Why does my house turn green again so fast?
Shade, humidity and nearby trees are usually the cause. If your house faces north or sits under a live oak canopy in Riverside or Mandarin, expect it to need cleaning more often than a house on an open sunny lot in Nocatee.
Can you wash a house if the paint is already peeling?
We can, but we will flag it during the walk-around. Water can lift loose paint further. Some customers repair first, some wash anyway knowing that. We let you decide.
What is the difference between house washing and pressure washing?
House washing uses a soft wash method, low pressure plus cleaning solution, designed for siding. Pressure washing uses high pressure and is for hard flat surfaces like driveways and concrete. Your house needs soft wash, not pressure wash.
