Custom Deck Design & Construction

Every Deck Starts with a Plan

Custom Decks Designed for Your Home

We don’t believe in one-size-fits-all. Every Alliance deck starts with a personal consultation, detailed measurements, and a design tailored to your home, your goals, and your budget. Whether you want a wraparound porch, a grilling platform, or a multi-level retreat, we’ll build something that complements your home’s style—and adds serious curb appeal.

From Idea to Blueprint

How Our Custom Deck Design Process Works

We meet at your home, walk the space, and sketch ideas together. We factor in sunlight, slope, existing structures, and local code. You'll get a clear design and a price to match—before any tools come out.

Deck Construction That’s Built to Code

After design approval, our team handles every step of construction—posts, framing, decking, stairs, and railings. We follow South Carolina’s building codes, use durable hardware and sealants, and make sure your new structure is safe, strong, and beautiful. We also take care of permitting and HOA approvals so you don’t have to.

Styles That Fit Any Space

Custom Deck Options We Offer

Your custom deck can be as simple or as detailed as you want. Add built-in benches, shade structures, planter boxes, or recessed lighting. Choose from pressure-treated wood, cedar, or composite brands like Trex and TimberTech. We’ll guide you through every option to build a space that works for the way you live.

Design That Solves Real Problems

Smart Deck Layouts for Any Lot

Uneven ground? Limited space? HOA limits? We’ve worked with every type of challenge across South Carolina. Whether you need a small elevated deck, a structure that works around existing trees, or one that hides a septic lid, our team builds solutions, not just structures. We measure twice and build once.
