San Diego climate is brutal on deck wood. UV intensity + dry summer + occasional marine layer = faster stain breakdown than most homeowners expect. Here's the cycle reality.
Year 0: New deck or fresh restoration
Stain looks rich, water beads on the surface, wood is protected.
Year 1-2: Beginning to gray
Stain fading visible in high-sun areas. Water still beads in some areas. Wood is still protected but starting to lose UV protection.
Year 2-3: Major gray-out
Stain mostly gone in sun-exposed areas. Water no longer beads. Wood is starting to absorb moisture again. Time for restoration.
What restoration includes
Pressure wash to remove old stain residue + surface dirt. Light sanding to open up wood grain. Apply quality stain/seal — typically 2 coats.
What it costs
Wash only: $245 typical deck. Wash + sand + stain: $895-1,500 depending on size.
Why people skip and pay later
If you skip restoration, the wood absorbs moisture year over year. Cupping, splitting, and rot start at year 5-7. Replacing deck boards: $4-8/sqft.
The math
$895 restoration every 2-3 years = $300/year average.
Skipping until replacement: $4-8/sqft × 200 sqft typical deck = $800-1,600 in board replacement plus full restoration = $2,500+.
The cheapest deck maintenance is the kind that happens every 2-3 years.
