When it comes to maintaining the beauty and safety of your outdoor living space, replacing deck boards is a crucial task. Over time, weather, wear, and natural aging can take a toll on your deck, especially here in the Seattle area where moisture and seasonal changes are constant. Whether you live in Kirkland, Bellevue, Bothell, or nearby communities, knowing your options and the associated costs can help you make informed decisions that protect your investment and enhance your home’s curb appeal.


What Influences Deck Board Replacement Cost?


Replacing deck boards involves several factors that influence the overall cost. Understanding these can help you budget effectively and choose the best materials and methods for your home.


Material Choice


The type of material you select for your new deck boards plays a significant role in the price. Common options include:


  • Pressure-Treated Wood: This is the most affordable and widely used option. It resists rot and insects but requires regular maintenance.

  • Cedar or Redwood: These natural woods offer better resistance to decay and a beautiful finish but come at a higher price.

  • Composite Decking: Made from recycled wood fibers and plastic, composite boards are low-maintenance and durable but cost more upfront.

  • PVC Decking: Fully synthetic, PVC decking is highly resistant to moisture and fading but is typically the most expensive option.


Labor and Installation


Labor costs vary depending on the complexity of the job and the contractor’s rates. Removing old boards, preparing the deck frame, and installing new boards require skill and time. In the Seattle area, labor rates can fluctuate, but quality workmanship ensures your deck lasts longer and looks great.


Deck Size and Accessibility


The size of your deck directly impacts the amount of material and labor needed. Larger decks require more boards and time to replace. Additionally, decks that are difficult to access or have unique designs may increase labor costs.


Additional Repairs


Sometimes, replacing deck boards reveals underlying issues such as damaged joists or supports. Addressing these problems is essential for safety but can add to the overall cost.
