Why Deck & Fence Cleaning Matters

Decks and fences are among the most noticeable and well-used features of any home, providing outdoor living space, privacy, and property value. Unfortunately, they are also constantly exposed to Portland's weather conditions, making them vulnerable to damage from moisture, algae, and sunlight. Without regular upkeep, wood surfaces can quickly deteriorate, leading to costly repairs or early replacement. Routine professional cleaning helps homeowners protect their investment and enjoy a more attractive outdoor space.

The Pacific Northwest's unique climate accelerates the aging process of outdoor wood. Frequent rain and damp winters create ideal conditions for moss, algae, and mildew to thrive on decks and fences. Shaded areas often become slippery and discolored, while constant moisture can promote wood rot and weaken structural integrity. During the summer, UV rays contribute to further damage by drying out the wood, causing cracks, splintering, and fading. This combination of moisture and sun exposure is especially hard on untreated or older wood surfaces.

At Pristine ProWash, we help homeowners fight back against these conditions. Our gentle, wood-safe soft washing process removes harmful organic buildup, revitalizes the wood's natural appearance, and reduces the risks of long-term damage. A clean deck and fence do more than improve your home's appearance. Regular cleaning extends the life of outdoor structures, keeps them safer to use, and ensures they remain a welcoming part of your outdoor living space for years to come.

How Pristine ProWash Does It

Every deck and fence cleaning project begins with a full inspection of your outdoor wood surfaces. We take the time to identify areas with heavy moss, algae, or mildew buildup, as well as sections showing signs of sun fading or moisture exposure. This upfront evaluation helps us tailor our approach to the condition of your deck or fence while ensuring all problem areas receive proper treatment. We also take extra steps to protect your landscaping by thoroughly soaking surrounding plants before and after the cleaning process.

Our soft washing method uses biodegradable, wood-friendly detergents that break down dirt, algae, and organic buildup without harming wood fibers or stripping protective finishes. Cleaning is completed using low-pressure rinsing equipment designed specifically for delicate wood surfaces, which prevents splintering, gouging, or water damage caused by improper high-pressure methods. The process restores natural wood tones, removes the dull gray appearance caused by oxidation, and leaves decks and fences looking refreshed and healthier.

Pristine ProWash finishes every job with a detailed rinse and optional final walkthrough to ensure results meet the highest standard. Most deck and fence cleaning projects in Portland fall between $200 and $400, depending on the size of the surface and the level of buildup. Every service includes before-and-after photo documentation, careful property care, and noticeable improvements in both appearance and lifespan of your outdoor spaces.
