What is the Best Wood for Deck Framing?

Considerations for Choosing Deck Framing Lumber 

Building a deck is a significant investment that adds value and functionality to your home. Choosing the right type of wood for the deck framing is crucial because the frame serves as the foundation for the entire structure. The best lumber for deck framing not only supports the weight of the deck but also withstands the elements over time. For homeowners and contractors planning to embark on a decking project, understanding which wood types offer durability, strength, and cost-effectiveness is key. Here’s an insightful guide to help you select the best lumber for your deck framing.

Durability Against Elements

The primary consideration for deck framing lumber is its ability to resist moisture, decay, and pest infestation. Since most decks are exposed to the outdoors, the wood must withstand varying weather conditions, including rain, snow, and intense sun.

Strength and Stability

The lumber should have the structural integrity to support the weight of the deck, furniture, and occupants. It must also maintain its shape and size against warping or twisting over time.


While it’s tempting to choose the cheapest options available, cost-effectiveness doesn’t just mean initial expense. It also involves considering the longevity and maintenance costs associated with the lumber.

Best Types of Lumber for Deck Framing

Pressure-Treated Lumber

Pressure-treated lumber is one of the most popular choices for deck framing due to its resistance to rot, decay, and insects. Typically made from softwoods like pine, this lumber is treated with chemicals that penetrate deeply to protect against environmental factors. It’s also cost-effective, making it a great option for those on a budget. However, ensure the chemicals used are suitable for residential use and that the wood is specifically rated for ground contact, if applicable.


Cedar is a natural choice for deck framing because of its inherent resistance to moisture, decay, and insect damage. It is also less prone to warping and splitting compared to other softwoods. Cedar offers a beautiful natural color and a pleasant scent, enhancing the aesthetic of your deck design. While it is more expensive than pressure-treated lumber, its durability and natural beauty can justify the cost for many homeowners.


Similar to cedar, redwood possesses natural oils that make it resistant to moisture, decay, and insects, making it an excellent material for outdoor applications like deck framing. Redwood is also stable, holding its shape well over time, which minimizes warping and twisting. The rich color of redwood can provide a striking look for your deck, but like cedar, it comes at a higher price point.

Composite Lumber

For those looking for an alternative to traditional wood, composite lumber is a viable option. Made from a blend of wood fibers and plastics, composite materials are designed to look like wood but offer increased durability and minimal maintenance. They resist rot, warping, and insect damage. Composite lumber is ideal for the frame and can be used for the decking itself, providing a long-lasting, uniform appearance.

Tips for Installation and Maintenance

Proper Installation

Ensure that the lumber is installed properly by following best practices for spacing and securing. This prevents moisture buildup and prolongs the life of the deck frame.

Regular Maintenance

Even the best lumber for deck framing requires maintenance. Regularly check for signs of wear or damage and address these issues promptly. Treat natural wood annually with a suitable sealant to preserve its integrity and appearance.

Consult with a Professional

Always consult with a professional contractor to choose the best lumber for your specific climate and soil conditions. Their expertise can ensure that your deck is both durable and safe.
