Deck & Fence Cleaning Jacksonville

By Jax Pressure Washing · Updated October 2026

Wood does not age gracefully in Jacksonville. Pressure-treated pine - the most common decking and fencing material in Florida - turns a dull gray within a year or two of sun exposure, and the shaded sections grow green mildew that makes boards slippery and fences look neglected. A deck or fence that was a selling point when it was new can become an eyesore you stop noticing until a guest points it out.

Jax Pressure Washing restores wood with a careful clean-and-brighten process, not a brute-force blast. Wood is soft compared to concrete, so pressure alone either leaves the gray behind or chews up the surface - there is no middle ground with a wand. We use wood-safe cleaning solutions that lift the gray weathering and kill the mildew, moderate pressure that cleans without gouging, and a brightening treatment that brings back the wood's natural warm tone.

The same approach works for the long fence lines that run along so many Jacksonville properties. A clean fence frames the whole yard, and it is often the first thing a buyer or an HOA notices. Call (904) 555-0134 for free quotes.

Deck & Fence Cleaning

What Florida Weather Does to Wood

Pressure-treated pine is built to resist rot and insects, but it has no defense against the two things that age it fastest: UV and moisture. Jacksonville gets plenty of both. UV breaks down the wood fibers at the surface, which is what turns boards that familiar silvery gray. Meanwhile the humidity feeds mildew on any board that stays damp - under railings, on the north side of fences, anywhere the sun does not reach.

The result is wood that looks old long before it is old. A three-year-old deck can look like a fifteen-year-old deck. The good news is that the gray is almost entirely surface-level. Underneath that weathered layer, the wood is usually sound - and a proper cleaning reveals it.

The process

How We Clean Decks Without Damaging Them

Wood cleaning is where technique matters most. Too much pressure gouges soft pine, leaves fuzzy splintered fibers, and etches permanent wand marks into the boards. Too little does nothing to the gray. The right approach is a process, not a pressure setting.

Our deck cleaning process

• Apply a wood-safe cleaning solution that loosens gray UV weathering, mildew, and grime
• Clean at moderate, controlled pressure - enough to rinse the solution and lifted grime, never enough to cut into the wood
• Treat stubborn mildew spots and shaded areas individually rather than cranking up the pressure
• Finish with a wood brightener that neutralizes the cleaner and restores the natural warm tone of the pine

The brightening step is what separates a real wood restoration from a simple wash. Without it, cleaned wood can look flat and washed out. With it, the grain comes back and the deck looks close to the day it was built.

Composite Decks Need Care Too

Composite decking was sold as maintenance-free, and plenty of Jacksonville homeowners have learned the hard way that it is not. Composite boards do not gray like wood, but the textured surface traps pollen, mold, and mildew just as happily - and the shady, damp corners of a composite deck can turn black-green within a couple of seasons.

Composite is actually easier to damage than most people expect. High pressure can scar the cap layer and void the manufacturer's warranty, so we clean composite at low pressure with solutions made for the material. No aggressive blasting, no heat, no harsh chemicals that break down the capping. A gentle soft wash brings composite back to its original color without the risk.

Fences: The Long Lines That Frame Your Yard

A fence is hundreds of linear feet of highly visible surface, and in Jacksonville's climate the whole thing weathers at once. Wood privacy fences go gray and grow mildew on the shaded side. The bottom boards near the soil stay damp and darken. Sprinkler heads leave mineral stripes. And because fences are so long, the transformation after a cleaning is dramatic - it is like getting a new fence for a fraction of the cost.

We clean both sides of the fence where we have access, because cleaning only your side leaves a visible line at the property edge and does nothing for the neighbor's view. If your fence backs up to a common area or an HOA-maintained space, mention it when you call - we will plan the access accordingly. Chain-link and vinyl fences get dirty too, mostly with algae film and pollen, and they clean up quickly with a soft wash.

After Cleaning: Keeping Wood Looking Good

Here is the honest part: cleaning resets the clock, but it does not stop it. Bare wood in Jacksonville will start graying again within a year if it is left unprotected. If you want the restored look to last, the next step after cleaning is sealing or staining the wood - the cleaning preps the surface perfectly for it, and stain or sealer is what actually blocks the UV that causes graying.

We do not sell staining as part of this service, and we are upfront about that: cleaning is the prep, protection is a separate job. What we can tell you is that a deck cleaned and then sealed within a few weeks will hold its color for years, while a deck that is only cleaned will need another wash sooner. Either way, an annual wash keeps mildew from taking hold and keeps the wood healthy between treatments.
