TL;DR

Pressure-washing PSI must match the surface (concrete 3000, wood 1200). Pre-treat with detergent before pressure washing. California gutters need cleaning twice a year, more if you have oaks or pines. Stainless micro-mesh gutter guards last 20+ years. Re-stain decks every 2 years.

California's marine air, oak leaves, pine needles, and Santa Ana winds create a unique exterior maintenance schedule. Skip these for a year and you start losing curb appeal.

Pressure Washing — PSI by Surface

The mistake amateurs make: same pressure on every surface. The right approach:

  • Concrete (driveway, patio) — 2,500-3,000 PSI, 25° tip
  • Wood (deck, fence) — 1,200-1,500 PSI, 40° tip, work with the grain
  • Vinyl siding — 1,500 PSI max, 40° tip
  • Stucco — 1,500 PSI, soft wash with detergent first

Wood at 3,000 PSI etches the wood. Stucco at 3,000 PSI strips the finish.

Pre-Treat Before Pressure Washing

The pressure does not actually do most of the cleaning — the detergent does. Pre-treat with Krud Kutter, let it sit 5-10 minutes, then pressure wash.

Gutter Cleaning — Twice a Year, Minimum

California schedule:

  • Late spring (after spring blooms drop) — clear bloom debris before summer fire season
  • Late fall (after leaves drop) — clear leaves before winter rains

Homes with oaks or pines may need cleaning 3-4 times a year.

Gutter Guards — Worth the Money on Tree-Lined Lots

Stainless steel micro-mesh gutter guards keep oak leaves and pine needles out while letting water flow. Foam guards collapse, plastic guards crack in UV — only stainless mesh lasts 20+ years.

Graffiti Removal — Speed Matters

Graffiti is much easier to remove in the first 48 hours. After a week, it has cured into the surface and may need pressure washing + degreaser + repainting.
