Questions About Cost, Care, and Installation
What Homeowners Want to Know About Composite Decks
If you’re new to composite decking, you probably have a few questions—about pricing, durability, and how it compares to wood. Here are the most common answers we give clients before building begins.
Is composite decking more expensive than wood?
Upfront, yes—but it saves money long-term by eliminating staining, sealing, and repairs.
Is composite decking worth the higher upfront cost?
Yes. While it costs more initially, you’ll save on repairs, staining, and replacements over time. It’s a smart long-term investment for durability and ease.
Will composite decks get hot in the Missouri sun?
Some darker colors can retain heat, but we offer lighter finishes and vented board designs that reduce heat buildup and improve comfort.
Can composite boards be cut and shaped like wood?
Yes. We cut, shape, and install composite just like wood, allowing for custom layouts, borders, and curved edges — all with a clean, finished look.
