Los Angeles Deck & Patio Pressure Washing
Decks and patios in Los Angeles face constant exposure to weather, foot traffic, and biological growth. Wood decks accumulate algae, mildew, and UV-grayed surfaces that make them look far older than they are. Composite decks develop mold and mildew in the grooves. Concrete patios stain from plant matter, food spills, and general wear. Pressure washing restores all of these surfaces — the key is matching pressure and method to the material.
Deck and patio washing in Los Angeles typically costs $100–$300 depending on surface size and type. A 200 sq ft wood deck runs $100–$175. A 400 sq ft composite deck or concrete patio runs $150–$300. 30 of 30 verified providers in Los Angeles include deck washing in exterior cleaning packages. Service areas cover the Los Angeles area including Los Angeles County, Pasadena, Southern California. Bundling deck washing with house or driveway washing usually saves $50–$100.
Wood decks in Los Angeles require low-pressure washing (500–1,000 PSI) to avoid raising wood grain or damaging fibers. After washing, many Los Angeles homeowners follow with a deck stain or sealant application — pressure washing prep is often included in staining quotes. Composite decks need even less pressure — the main goal is cleaning mold and mildew from grooves without scratching the surface. Concrete patios can handle higher pressure (2,000–3,000 PSI) for heavy stain removal.

Deck & Patio Pressure Washing FAQ — Los Angeles
How much does deck pressure washing cost in Los Angeles?
Deck washing in Los Angeles costs $100–$175 for a small wood deck (200 sq ft) and $150–$300 for a 400 sq ft deck or patio. Composite decks cost about the same as wood. Bundling with house or driveway washing usually saves $50–$100. Compare quotes from 30 providers in Los Angeles for your specific surface area and material.
Can a wood deck be pressure washed in Los Angeles?
Yes, but with caution. Wood decks should be washed at 500–1,000 PSI maximum — too much pressure raises wood grain, damages fibers, and leaves furry or splintery surfaces. Experienced Los Angeles pressure washing companies use low-pressure soft wash techniques for wood and always keep the nozzle moving. Ask your provider what PSI they use on wood decks before hiring.
Should I seal my deck after pressure washing in Los Angeles?
For wood decks, absolutely — washing opens the wood grain and is the perfect preparation for stain or sealant. Allow the wood to dry completely (24–48 hours) after washing before applying finish. Many Los Angeles pressure washing companies offer deck staining as a follow-on service, or coordinate with deck contractors. For composite decks, sealing is not necessary — cleaning is sufficient.
How often should I pressure wash my deck in Los Angeles?
Wood decks in Los Angeles should be washed and refinished every 1–2 years to maintain appearance and protect the wood. Composite decks benefit from annual cleaning to prevent mold and mildew in grooves. Concrete patios typically need washing every 1–3 years depending on exposure and use. Annual deck washing before summer entertaining season is the most popular schedule.
