Get matched with top deck cleaning pros in Lizella, GA

Many composite decking manufacturers, including the popular Trex brand, offer warranties that protect against warping under specific conditions. These warranties typically last between 20 and 50 years, but they usually exclude claims related to improper installation of the product. Some manufacturer warranties only cover decks built by certified professionals.

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.

A deck doesn’t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems. 

When sourced responsibly, the most sustainable wood decking options are timber trees like redwood, pine, Douglas fir, Nootka cypress, and Western red cedar. These tree species are fast-growing with low carbon emissions. Plus, most timber woods make durable deck materials because of their resistance to rot and decay over time.
