Correct-PSI cleaning for pine, cedar, redwood, and composite decking and fencing. We lift mildew, tannin streaks, snow mold, and pollen film without shredding the wood — and prep your deck for restaining or sealing.
Flagstaff decks and fences face winter snow, monsoon mildew, and harsh UV at 6,910 feet — and the wrong pressure ruins them faster than dirt ever would.
Soft pine takes less than 600 PSI before the grain starts to fuzz. Cedar and redwood are slightly more forgiving but still soft. Composite has a different surface entirely. We dial in pressure for each board and test in a hidden spot first so we never leave wand marks on visible decking.
In shaded yards across Cheshire, Coconino Estates, Forest Highlands, and Mountain Dell, snow can sit on decks and fences for months. The result is snow mold, mildew, and algae deeply embedded in the grain. We use a wood-safe cleaning solution that kills the spores instead of just blasting them off.
Stain and sealer won't bond to dirty wood. Cleaning is the most important step in any deck restoration. We clean, let the wood dry for 48 to 72 hours, and turn your deck over to your stain crew ready to absorb.
Every deck and fence cleaning includes a wood-safe wash, full rinse, and walk-through with you afterward so we can flag any boards that need attention.
Like all pressure washing in Flagstaff, deck and fence cleaning is a seasonal service that runs April through October. The right time depends on what you're trying to fix:
It will if the PSI is wrong. Pine and cedar are soft woods, and the wrong nozzle and pressure will shred the grain and leave a fuzzy, splintered surface. We use lower pressure with a wood-safe cleaning solution that lifts dirt, mildew, and tannin streaks without chewing up the wood. We test on a hidden area first and adjust before cleaning the visible decking.
Yes. Composite decking like Trex and TimberTech is durable but the surface can be scratched or fuzzed by too much pressure. We use the lowest effective pressure plus a composite-safe detergent that breaks down pollen, mildew, and the green algae film that grows on shaded composite boards in Flagstaff. We follow the manufacturer's cleaning recommendations.
Snow mold and mildew are common on shaded fences and the underside of decks in Flagstaff, especially after long winters in places like Cheshire, Coconino Estates, and Forest Highlands where snow lingers. Our cleaning solution kills the mold spores so they don't grow back as quickly, then we rinse and let the wood fully dry before any sealing.
Yes. Stain and sealer won't bond properly to dirty or mildewed wood. Cleaning is the most important prep step. We clean the wood and let it dry for 48 to 72 hours, then your stain or sealer can be applied. We can recommend the right time for restaining based on the wood and exposure.
