Deck Staining & Sealing in Corte Madera — FAQ

How often should I stain my deck in NorCal?+

Semi-transparent stain lasts 2–3 years on horizontal surfaces. Solid stain lasts 3–5 years. Decks in full sun (common in the Sacramento Valley) need more frequent maintenance.

Oil-based vs. water-based deck stain?+

Oil-based stains penetrate deeper and last longer on decks. Water-based stains are easier to clean up and lower VOC. For NorCal's hot, sunny climate, oil-based is generally the better performer on decks.

Can I stain a new deck right away?+

Pressure-treated lumber should weather for 3–6 months before staining. Cedar and redwood can be stained after 30 days of dry weather. A water bead test helps determine readiness.
