Deck Builder in St. Louis, MO | Custom Decks | Atlas General Contracting
Custom Decks Built to Last in Missouri's Four Seasons
St. Louis weather is tough on outdoor builds — freeze-thaw cycles, humid summers, and Missouri hail demand materials and construction methods that actually hold up. Atlas General Contracting has been building decks for Missouri homeowners for over 45 years.
Professional Decks Services in the St. Louis Metro
We build decks in all three major material categories: composite (Trex, TimberTech, Azek), natural cedar, and pressure-treated. Most of our St. Louis clients are moving to composite decking because the long-term maintenance story is dramatically better in our climate — no annual sealing, no splinters, no cupping boards.
Every deck we build is engineered with proper footings (below frost line), hidden fastener systems for a clean surface, and code-compliant railings. We also build pergolas, gazebos, screen-ins, and outdoor kitchens as deck add-ons — an increasingly popular request across the St. Louis metro.
Deck permits, HOA approvals in communities like Wildwood and Chesterfield, and material selection are all handled by us. You get one price, one crew, and one timeline — typically 2-4 weeks from demo/build start to final inspection.
