Decks and patios in Jacksonville 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 Jacksonville 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. 42 of 42 verified providers in Jacksonville include deck washing in exterior cleaning packages. Service areas cover the Jacksonville area including Northeast Florida, St. Augustine, surrounding areas. Bundling deck washing with house or driveway washing usually saves $50–$100.
Wood decks in Jacksonville require low-pressure washing (500–1,000 PSI) to avoid raising wood grain or damaging fibers. After washing, many Jacksonville 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.

Can a wood deck be pressure washed in Jacksonville?
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 Jacksonville 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 Jacksonville?
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 Jacksonville 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 Jacksonville?
Wood decks in Jacksonville 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.
