Deck and Fence Pressure Washing / Soft Washing
VINYL AND COMPOSITE FENCES AND DECKS:
Decks and fences take a beating from Missouri weather -- rain, humidity, pollen, and shade create the perfect conditions for mold, algae, and green staining to build up fast. Our composite deck and fence pressure washing uses a soft wash method that removes that buildup safely from vinyl and composite surfaces without causing damage.
We evaluate every surface before we start and select the right pressure level and cleaning solution for the material. Vinyl gets a different approach than composite. Every job is performed by trained, background-checked, in-house technicians using commercial-grade equipment. We back all work with a 100% satisfaction guarantee.

WOOD FENCES AND DECKS:
Our wood cleaning service is designed to remove dirt, algae, mold, mildew, and organic buildup from wood fences and decks to improve their appearance and help maintain the surface. Please note, this is a cleaning service — we do not provide wood restoration or prep surfaces for painting or staining.
Composite Deck & Vinyl Fence Cleaning
Composite decking and vinyl fencing require gentle, material-specific cleaning to preserve their appearance and finish. These surfaces should never be pressure washed aggressively or treated like natural wood.
Castellan Pro Wash uses soft wash systems and proven detergents to remove algae, dirt, pollen, and organic buildup without etching, discoloration, or surface wear.
Why Homeowners Trust Our Deck and Fence Cleaning
Maintenance Cleaning for Wood Decks & Fences
Natural wood decks and fences are cleaned using soft washing methods only. Our process removes surface-level dirt, mold, and organic buildup while minimizing stress on wood fibers.
We do not perform wood restoration, oxidation removal, or stain preparation. Our services are limited to safe maintenance cleaning designed to preserve the existing condition of the wood.
- Low-pressure cleaning only
- No aggressive stripping or surface alteration
- Designed for maintenance, not restoration
Why Soft Washing Matters
Deck and fence materials expand and contract with changing weather conditions. Aggressive cleaning forces water and debris deeper into the surface, accelerating wear, splintering, and premature failure.
Soft washing removes organic buildup without disrupting surface integrity, making it the safest method for composite, vinyl, and maintained wood surfaces.
Castellan Pro Wash prioritizes controlled execution over short-term visual impact.
