1. Pressure Treated Wood
Still the most common choice in St Louis due to the low upfront cost.
- Pros: Cheapest option, natural look, structural strength.
- Cons: Warps/cracks over time, requires annual staining, splinters.
2. Composite Decking
A blend of wood fibers and plastic. This is the new standard for "low maintenance" living.
- Pros: No rotting, no painting, consistent color.
- Cons: Can get hot in the sun, heavier than wood.
3. Cellular PVC
100% plastic (no wood fibers). The premium choice.
- Pros: Best warranty, coolest on bare feet, zero chance of rot.
- Cons: Most expensive, can squeak if not installed correctly.
Our Recommendation for St Louis
If you plan to stay in your home for 5+ years, Composite offers the best ROI. The lack of maintenance costs (stain/sealant) means it pays for itself by year 4.
