Our Deck Staining & Sealing Process

01

Cleaning & Stripping

The deck is cleaned with a wood brightener or deck stripper to remove old stain, gray oxidation, and biological growth.

02

Sanding & Prep

Rough boards are sanded smooth, popped nails are countersunk, and any split or cracked boards are replaced.

03

Stain Application

Premium penetrating stain or solid color stain is applied by brush and roller for even, thorough coverage in all the wood grain.

04

Sealing

A UV-resistant sealer is applied as a final coat to lock in the stain and provide maximum weather protection.

Deck Staining & Sealing FAQ for San Francisco Homeowners

How often should San Francisco homeowners get deck staining & sealing?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from deck staining & sealing at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need deck staining & sealing?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How often should I stain my deck?
Penetrating stains typically last 2–3 years; solid stains can last 4–5 years. Horizontal surfaces like decking wear faster than vertical fence boards.
Should I use a solid stain or transparent stain?
Transparent and semi-transparent stains showcase wood grain and work best on newer wood in good condition. Solid stains cover grain but provide maximum protection and color — better for older or weathered wood.
Can you stain a pressure-treated deck?
Yes, but new pressure-treated wood should dry for 6–12 months before staining. We'll check moisture levels to confirm the wood is ready.
How long before I can use my deck after staining?
Light foot traffic is usually safe in 24–48 hours. We recommend waiting 72 hours before moving furniture back and a full week before heavy use.
