Deck Cleaning in Davidson, NC

Davidson's older neighborhoods around the college and South Street feature wood decks that have lived under deep oak and poplar canopy for decades. The result is heavy tannin staining, persistent mildew on north-facing sections, and pressure-treated pine that has weathered well past silver into a darker mottled gray. Restoration starts with a sodium percarbonate brightener at the higher end of dilution (6 oz/gal), dwelled 15 minutes with brush agitation on tannin-heavy boards, then rinsed with the grain at 1,200-1,500 PSI.

Davidson's older neighborhoods around the college and South Street feature wood decks that have lived under deep oak and poplar canopy for decades. The result is heavy tannin staining, persistent mildew on north-facing sections, and pressure-treated pine that has weathered well past silver into a darker mottled gray.

Some decks in River Run and Bailey Springs show failing semi-transparent stain that traps moisture. In those cases we discuss whether to strip with a sodium hydroxide-based stripper or simply clean and re-coat over the existing finish. Composite is less common in older Davidson but increasingly seen on additions; those get the under-1,200 PSI soft-wash protocol with dilute sodium hypochlorite.

Deck Cleaning FAQs for Davidson

Local-specific answers and common service questions

Our Davidson deck has black tannin stains that won't go away. Can you remove them?
Yes. Tannin responds to oxalic-acid-based brighteners after the initial sodium percarbonate cleaning. We do a two-step on heavily stained decks: oxygen-bleach clean, rinse, then a brightener pass to neutralize the tannin and even out tone.
Should we strip the old stain or clean over it?
Depends on adhesion. If the existing stain is failing in patches, stripping is the right call before re-coating. If it is uniformly worn, a clean and re-coat over the top works fine. We assess on-site before recommending.
How often should an old wood deck be cleaned in Davidson?
Under heavy canopy, annually. The combination of tannin drop, moisture retention, and mildew pressure is more aggressive than open-yard decks elsewhere in the area.
Is it safe to pressure wash a wood deck?
With the right technique, yes. We use low-pressure soft washing for wood decks specifically to avoid damaging the wood grain. High pressure on bare wood can cause splintering and raised fibers.
How often should I clean my deck in Charlotte?
Charlotte's humidity means most wood decks benefit from annual cleaning. Composite decks can often go 18–24 months between cleanings, but annual cleaning keeps algae from taking hold.
Do you clean Trex and composite decks differently than wood?
Yes. Composite decks require lower pressure and specific cleaning solutions to avoid damaging the surface or voiding the manufacturer's warranty. We adjust our approach for every deck material.
