Deck & Fence Cleaning in Mobile, AL | Salt Air Fix

If you live anywhere near downtown Mobile, Midtown, or the Cottage Hill corridor, you already know what a wet Gulf Coast summer does to wood. Decks get slick with algae. Fence boards go gray and feel almost furry when you run a hand across them. By July, a pine or cedar fence that looked decent in March can look like it belongs behind an abandoned warehouse. That is not neglect on your part. That is Mobile, Alabama doing what it does.

Baldwin Preaux Wash handles wood fence and deck cleaning across Mobile, including Midtown, Spring Hill, Cottage Hill, West Mobile near Tillman's Corner, and the older neighborhoods around Old Shell Road and Old Dauphin Way. We use low-pressure soft-wash chemistry on wood, never a high-pressure lance that strips grain and drives water into your boards. The goal is to kill what is growing, lift the grime, and leave the wood looking like wood again, not like a pressure-washed sidewalk.

Why Wood Goes Bad So Fast in Mobile

Mobile sits at the top of Mobile Bay. The humidity rarely drops below 70 percent in summer. Salt-laden air drifts up the bay, and afternoon thunderstorms keep surfaces wet for hours. Wood soaks that up. Algae, mildew, and a green-black biofilm called Gloeocapsa magma take hold fast. Once that film coats the surface, it traps moisture underneath, which is when wood starts to break down from the inside out. You end up with gray, splintery boards that actually hold water instead of shedding it.

We see this constantly in the 36604, 36605, 36606, and 36608 zip codes. Older homes in Midtown with wrap-around porches and original wood balusters are especially vulnerable because the overhangs limit airflow and keep the wood shaded and damp. The same goes for newer privacy fences in Spring Hill or Cottage Hill subdivisions where fast-grown pine was installed to keep costs down. Fast-grown pine is thirsty wood. Without a cleaning and a sealer, it grays out in a single season.

How We Clean Wood the Right Way

High pressure on wood is a mistake. A pressure washer running 2,500 PSI or more on a deck board fuzzes the grain, raises splinters, and can blast right through a softwood board if the operator is not careful. We use a soft-wash process: low-pressure application of a biodegradable cleaning solution, dwell time to let the chemistry do the work, and a gentle rinse. No gouging, no grain damage, no streaks.

Our Wood Cleaning Process Step by Step

• Walk the structure and check for rot, loose boards, or nails that need addressing before we start
• Pre-wet surrounding plants and grass to protect them from runoff
• Apply low-concentration sodium hypochlorite and surfactant mix at low pressure
• Let the solution dwell and break down algae, mildew, and biofilm
• Rinse thoroughly at low pressure to clear all residue
• Inspect with you and note any boards that would benefit from staining or sealing after the wood dries

We do not offer staining or painting, but we work with a handful of local contractors in the Mobile area who do. Once the wood is clean and dry, it takes stain and sealant much better because there is no biofilm layer blocking penetration. Homeowners who stain over dirty wood are basically sealing the mildew in. That is money wasted.

What We Commonly Find on Mobile Decks and Fences

• Black and green algae on horizontal deck surfaces, especially shaded boards near the house
• Green mildew streaks running down fence boards from capped posts that hold standing water
• Orange rust staining near metal post bases or galvanized screws that have started to oxidize
• Tannin bleed on cedar fences, a dark brown stain that looks like rot but is just a wood acid reacting with water
• Lovebug residue baked onto surfaces after spring and fall swarms, which speeds up surface breakdown
• Pollen buildup packed into gaps between fence boards that traps moisture and feeds mold

How Often Should You Clean Wood in Mobile

For most Mobile homeowners with an unsealed wood fence or deck, once a year is the minimum. If the wood is sealed and in decent shape, once every 18 months may be fine. If you have a shaded deck that stays wet after rain, or a fence line that runs along a property edge where neighbors have overgrown shrubs or a wet drainage ditch, you may need cleaning twice a year to stay ahead of the biofilm. The worst thing you can do is wait until the wood looks nearly black. At that point you may be cleaning, but you are also revealing boards that need replacement.

A Note on Composite and Hardwood Decks

Composite decking like Trex or TimberTech needs cleaning too. It does not rot the same way pine does, but it grows algae and mildew on the surface, which makes it dangerously slick and looks terrible. We adjust our mix and pressure for composite so there is no risk of surface pitting or voiding the manufacturer warranty. Ipe, teak, and other hardwoods are similar. We treat them gently and always rinse thoroughly. If you are unsure what you have, describe it when you call and we will walk you through the right approach before we ever show up.
