Deck & Fence Cleaning in Fort Collins

Gray, furry deck boards aren't worn out. That's surface oxidation and mill glaze — it comes off, and the wood underneath is usually fine.

What a wood clean covers

The fastest way to ruin a deck is to point a pressure washer at it. Too much force tears out the soft grain between the growth rings and leaves a furred surface that soaks up water and grays again within months. We clean wood with a percarbonate solution and the lowest pressure that will do the job, then follow with a brightener that neutralizes the cleaner and pulls the natural color back up.

  • Deck boards, rails and spindles
  • Stairs and stringers
  • Cedar and pine fencing
  • Pergolas and gazebos
  • Under-deck and joist faces
  • Wood brightening step included
  • Stain and seal prep
  • Composite decking (different method)

How the job runs

  1. Photos and a fixed priceWood varies a lot. Pictures of the worst section tell us what we're dealing with.
  2. Clean at low pressurePercarbonate solution and dwell time do the lifting, not force.
  3. Brighten and neutralizeThis step restores color and brings the pH back so a stain will bond properly.
  4. Dry and hand overWood needs 48 hours before sealing. If you're staining, we'll tell you exactly when it's ready.

Questions

Can you clean it right before I stain?
Yes, and that's the ideal order. Clean, brighten, let it dry a full 48 hours, then stain. Stain applied over a dirty or high-pH surface will not bond and it will peel.
My deck is gray. Is it too far gone?
Almost never. Gray is oxidized surface fiber, usually well under a millimeter deep. Underneath it the wood is normally sound.
Do you do composite?
Yes, and it takes a different approach — composite holds a surface film that responds to a specific cleaner rather than pressure.
