Deck & Fence Washing

Gentle restoration for wood and composite.

Wood deck being washed, half restored to natural color

Wood grays because UV and moisture break down its surface fibers — and mildew moves in behind it. High pressure makes it worse, furring the wood and gouging soft grain.

We use gentle pressure with wood-safe cleaners and brighteners to lift the gray layer and kill growth, restoring the natural tone of the wood. Composite decking gets its own dedicated process that’s safe for the cap layer.

FAQ

Common questions

Can you prep my deck for staining?

Yes — washing plus brightening is exactly the prep stain manufacturers call for. We’ll let you know when it’s dry enough to coat.

Is this safe for composite decking like Trex?
