Wood does not last forever on its own in Mobile, Alabama. The combination of Gulf Coast humidity, afternoon thunderstorms, and heat that runs from April through October gives mold, mildew, and algae exactly what they need to take over a wood fence or deck in a single season. If you live in Midtown, Spring Hill, West Mobile, or anywhere in the 36608 or 36609 zip codes, you have probably noticed a fence that started the year looking decent and ended it gray and streaked. That is not age. That is biology, and it cleans off.
Baldwin Preaux Wash handles wood fence and deck cleaning across Mobile and Baldwin County. We use low-pressure soft washing techniques on wood specifically because blasting raw wood with high-pressure water splits grain, raises fiber, and drives moisture deeper into the material. The right approach is a proper cleaning solution applied at safe pressure, given time to work, then rinsed clean. The result is wood that looks like wood again instead of something you are embarrassed to have in photos.
Why Mobile Wood Weathers So Fast
Mobile consistently ranks among the wettest cities in the continental United States. Average annual rainfall pushes 65 inches, and the humidity between May and September rarely gives wood a chance to fully dry between rain events. Add in the salt air drifting up from Mobile Bay and the Gulf, and you have conditions that accelerate biological growth on any porous surface. Cedar, pine, and treated lumber all absorb moisture. Once moisture sits in the grain, mold and algae spores have a food source and they go to work.
Neighborhoods like Midtown near Old Shell Road, the Spring Hill area around Airport Boulevard, and subdivisions out toward West Mobile along Cottage Hill Road all deal with the same issue. Large shade trees, which are a big part of what makes these neighborhoods attractive, also mean less direct sun drying out decks and fence boards. Less sun plus more moisture equals faster biological growth.
What We Actually Do on a Wood Cleaning Job
Every wood fence and deck job starts with a walkthrough. We look at what is growing, how deep the discoloration goes, whether the wood is painted, stained, or bare, and whether there are any boards that are soft or compromised. That matters because the cleaning process needs to be adjusted for the condition of the wood.
The Soft Wash Process on Wood
- Pre-wet surrounding plants, grass, and any surfaces that could be affected by cleaning solution runoff
- Apply a biodegradable cleaner formulated for organic growth on wood at low pressure
- Allow dwell time so the solution breaks down mold, mildew, algae, and embedded grime at the surface level
- Rinse thoroughly at controlled low pressure to clear the surface without raising wood grain
- Final inspection to confirm even cleaning across all boards and rails
We do not skip the dwell time. That step is what separates a clean that lasts from a rinse that looks fine for two weeks and then comes back. The cleaning chemistry kills the organism. The rinse removes it. Both steps are necessary.

Fences vs. Decks: Different Challenges
Fences and decks are both wood, but they collect different kinds of buildup and they face different risks during cleaning.
Fences
Privacy fences in Mobile neighborhoods often run along property lines where they are shaded by trees on both sides. That constant shade keeps them damp. The north-facing boards especially develop heavy green algae and black mold streaking. Picket fences in older Midtown lots are usually painted, which means cleaning has to be gentle enough not to strip paint. We adjust solution concentration and pressure accordingly. A painted fence that gets cleaned too aggressively just needs repainting sooner, which defeats the purpose.
Decks
Decks collect leaf litter, standing water in low spots, and foot traffic grime on top of normal mold growth. The horizontal surface means water sits rather than runs off, which is why deck boards often show worse discoloration than vertical fence boards in the same yard. Composite decks can also be cleaned with soft washing, though the chemistry is adjusted for the material. Wood decks that have never been sealed are especially porous and absorb growth deep into the grain, so they may need more dwell time.

Should You Seal the Wood After Cleaning?
Sealing is not something Baldwin Preaux Wash sells as a bundled upsell. Here is the honest answer: bare or lightly stained wood benefits from a water-repellent sealer after cleaning because it slows down the next round of moisture absorption and biological growth. If your deck or fence is bare wood and you want it to stay cleaner longer, sealing makes sense. If it already has a solid stain or paint in good condition, the existing coating is doing that job and you do not need to add another product on top.
What we will tell you after a cleaning job is what the wood looks like, what condition it is in, and whether it would benefit from a sealer before the next Mobile summer hits. That conversation costs you nothing. Call us at (251) 978-5503 and we can talk through your specific situation.
How Often Should Wood Be Cleaned in Mobile?
For most Mobile homeowners, once a year is the right interval for wood fencing and decks. Early spring before the worst of the humidity hits is a good time to get ahead of the season. Fall cleaning after the summer growth cycle is also popular, especially if you plan to reseal or refinish before winter. Homes with heavy tree cover or north-facing wood surfaces sometimes need cleaning twice a year. We can tell you where your property lands after the first visit.

Frequently Asked Questions
Will soft washing raise the grain on my wood deck boards?
Not when it is done correctly. High-pressure washing absolutely raises grain and can split wood fibers. Soft washing uses low pressure with a cleaning solution that does the actual work. The rinse pressure we use on wood is well below what would damage the surface. If a contractor tells you they pressure wash wood decks at full pressure, that is a red flag.
How long does a wood fence or deck cleaning take?
Most residential jobs in Mobile take between one and three hours depending on the size and condition of the wood. A standard privacy fence around a typical Spring Hill or Midtown backyard usually runs two hours or less. Larger decks or fences with heavy mold growth may take longer because we allow proper dwell time for the cleaning solution to work before rinsing.
Can you clean a painted wood fence without stripping the paint?
Yes. We adjust our cleaning solution concentration and pressure when working on painted wood. The goal is to clean the surface, not remove the existing coating. Older paint that is already peeling or flaking may show some additional loosening, which is worth discussing before the job starts so there are no surprises.
My deck has never been cleaned and has years of buildup. Is it too far gone?
Usually not, unless there is structural rot in the boards themselves. Even heavily discolored or green wood typically responds well to soft wash cleaning. We have cleaned decks in Mobile that homeowners assumed were past saving and the wood came back looking much better than expected. We are happy to take a look and give you an honest assessment before any work begins.
Do you service areas outside of Mobile proper, like Saraland or Tillman's Corner?
Yes. We run crews throughout Mobile County including Saraland, Satsuma, and Tillman's Corner regularly. We also cover the Eastern Shore in Baldwin County. If you are unsure whether we reach your address, call (251) 978-5503 and we will confirm availability quickly.
What is the difference between deck cleaning and deck refinishing or staining?
Cleaning removes biological growth, dirt, and surface discoloration from the wood. Refinishing or staining applies a new coating to the wood surface. We do the cleaning side. Once the deck is clean and dry, it is in the best possible condition for a staining or sealing contractor to do their work. Many homeowners get a professional cleaning done first specifically because stain adheres better to a clean surface.
