Deck Cleaning
Refresh your outdoor living space by addressing dirt, organic buildup, and exterior discoloration with cleaning methods suited to your decking material.
Decks & Outdoor Living
Bring New Life to Your Outdoor Space
Your deck is an extension of your home—a place to relax, entertain, and enjoy time outdoors. With regular exposure to sunlight, rain, moisture, and surrounding vegetation, decking surfaces can develop dirt, discoloration, and organic buildup.
Professional deck cleaning helps refresh the appearance of your outdoor space while considering the material, existing finish, and condition of the surface. Wood, composite, and PVC decking each require an appropriate cleaning approach.
Decking Materials
Cleaning for Different Deck Types
Decking materials vary in durability, texture, finish, and maintenance requirements. Choosing the right cleaning method begins with understanding the surface.
Pressure-Treated Wood
Pressure-treated decking can accumulate dirt, algae, and weather-related discoloration. Cleaning should account for the wood's condition and any existing stain or sealer.
Cedar & Natural Wood
Natural wood decking can develop organic buildup and discoloration from prolonged outdoor exposure. Appropriate cleaning helps address buildup without relying on excessive pressure.
Composite Decking
Composite decking can collect dirt, pollen, and organic buildup. Cleaning methods should account for the product's surface and manufacturer recommendations.
PVC & Manufactured Decking
PVC and other manufactured decking products may have specific cleaning requirements. Surface finishes and product guidance should be considered before treatment.
Common Deck Concerns
What's Building Up on Your Deck?
Decks experience a combination of foot traffic, changing weather, moisture, and environmental exposure. These conditions can contribute to visible buildup and changes in appearance.
- Dirt and environmental grime
- Green algae and organic buildup
- Dark discoloration in shaded areas
- Mildew-related staining
- Pollen and seasonal debris
- Food and beverage staining
- Weather-related discoloration
Some discoloration may be associated with aging, UV exposure, deteriorated finishes, or changes within the decking material. Cleaning may improve appearance without reversing those conditions.
The Cleaning Approach
Care Matters When Cleaning Decks
Deck cleaning is not simply a matter of applying the highest possible water pressure. Different materials respond differently to cleaning equipment and products.
Wood decking can be damaged by excessive pressure, which may raise the grain or cause splintering. Composite and manufactured decking products may have specific requirements involving cleaning solutions, pressure, and surface finishes.
The appropriate method should account for the decking material, existing condition, manufacturer guidance, and the type of buildup being addressed.

Good to Know
Frequently Asked Questions
Have questions? Here are a few things to know before scheduling your service.
What types of decks can be cleaned?
Common decking materials include pressure-treated wood, cedar, composite, PVC, and other manufactured decking products. Each material has different cleaning requirements, so the appropriate approach depends on the surface, its condition, and manufacturer recommendations.
Can deck cleaning remove green algae?
Deck cleaning can address many types of algae-related discoloration and organic buildup. Results depend on the decking material, the extent of the growth, and the condition of the surface.
Is pressure washing safe for wooden decks?
Wood requires careful cleaning because excessive pressure can raise the grain, cause splintering, and damage weathered boards. Cleaning methods should be selected according to the wood species, condition, and existing finish.
Can cleaning restore weathered wood to its original color?
Cleaning can remove applicable surface buildup and improve the appearance of wood, but natural aging, UV exposure, and permanent discoloration may remain. Sanding, staining, and refinishing are separate services.
Can composite decking be cleaned?
Many composite decking products can be cleaned, but cleaning requirements vary by manufacturer and product. Certain chemicals, excessive pressure, or abrasive methods may affect the surface or finish.
Will deck cleaning remove old paint or stain?
Routine deck cleaning is not the same as paint stripping or stain removal. Existing coatings may be affected by cleaning, particularly when they are already deteriorating. Any stripping or refinishing work should be discussed separately.
Can you clean deck railings and stairs?
Railings, stairs, posts, and other deck features can have different materials and cleaning requirements. Mention the areas you would like addressed when requesting your quote so the scope of work can be discussed.
How often should I have my deck cleaned?
Cleaning frequency depends on the material, shade, surrounding vegetation, moisture, foot traffic, and visible buildup. Decks beneath trees or in damp areas may need more frequent attention.
Do I need to prepare my deck before cleaning?
It is helpful to discuss outdoor furniture, planters, decorations, grills, and access requirements before the appointment. South Hills Soft Wash can provide preparation instructions appropriate for your property.
