Deck and Fence Restoration: Bringing Gray, Weathered Wood Back to Life

Gray wood is not ruined wood. In most cases it is one careful cleaning away from looking new.

Untreated wood exposed to sun and rain turns silver-gray as the surface fibers break down, and shaded sections grow green and black mildew. Both are surface-level problems, and both are fixable — if the cleaning is done correctly.

Why high pressure ruins wood

Wood is soft. Aggressive pressure carves out the softer growth rings, leaving a rippled, splintered, fuzzy surface that traps dirt worse than before and refuses to hold stain evenly. Once boards are furred, sanding is the only fix.

Our approach

• Wood-safe cleaner applied and given time to break down mildew and gray fiber
• Low pressure, wide fan, always working with the grain
• Neutralizing rinse where the cleaner requires it, so stain adheres later
• Full dry time before any coating is discussed

Composite decking

Composite does not gray, but it absolutely grows mold in the texture grooves. It is cleaned at low pressure with the appropriate solution — never scrubbed aggressively, which scratches the cap layer.

When to stain or seal

Wait for the wood to dry fully — typically 48 hours of dry weather after cleaning. Sealing damp wood traps moisture and causes the finish to peel within a season. Cleaning first is non-negotiable: stain over mildew simply seals the mildew in.
