Materials We Use

Quality Composite Materials, Not Cheap Substitutes

The frame under your boards matters as much as the boards themselves. As a quality-first composite deck builder in St. Louis, we only install products we would use on our own homes.

Capped Composite Decking Boards

A tough polymer shell wraps the core to resist fading, stains, mold and moisture, which helps the boards handle Missouri weather.

Strong, Properly Spaced Framing

We follow the board maker's joist spacing rules and use pressure-treated lumber or steel framing, sized to your deck height and budget.

Secure Ledger and Hardware

A correctly attached ledger board and the right connectors keep your deck safe and your manufacturer warranty intact.

Railings That Match Your Style

Choose aluminum, cable or composite railings, plus matching fascia and picture-frame borders for a finished, custom look.

Our Guarantee

Our Deck Warranty, In Plain English

We back our work with warranties that actually mean something. No fine print designed to exclude your claim.
