Cedar vs. Pressure-Treated Pine: Choosing Your Deck Wood

Cedar and pressure-treated pine are the two most common wood choices for decks in our area, and both can look great and last for years — but they age differently, and the right pick depends on what you value most.

Cost

Pressure-treated pine is typically 20–35% less expensive than cedar for the same square footage, which is often the deciding factor for larger deck footprints.

Rot and Insect Resistance

Cedar contains natural oils that resist rot and deter insects without chemical treatment. Pressure-treated pine is chemically treated to resist the same threats, but the protection is concentrated near the surface — deep cuts or drilled holes should be treated with sealant to protect the exposed untreated core.

Appearance

Cedar has a tighter, more consistent grain and takes semi-transparent stain beautifully, which is why it's often chosen for more visible, higher-end builds. Pressure-treated pine has a coarser grain and is more prone to knots, but performs well with solid stain that doesn't rely on showing off the grain.

Stability

Cedar tends to warp and cup less over time than pressure-treated pine, particularly in boards that see direct, intense sun exposure through a San Antonio summer.

1. Choose pressure-treated pine if budget is the top priority and you're comfortable staining every 1–2 years.
2. Choose cedar if you want a more refined look, slightly better long-term stability, and don't mind the added upfront cost.
3. Choose composite if you'd rather not think about either wood species' maintenance schedule at all.
