Custom Deck Design & Construction in Vermont

Designs That Fit Your Space, Style & Budget

Start with a Deck That’s Built Just for You

A truly custom deck doesn’t start with a kit—it starts with your home, your goals, and how you want to use the space. At Alliance Deck Builders of Vermont, we create made-to-measure layouts that match your property’s shape, slope, and views. We take time to understand your vision and build to match—from size and stair locations to rail styles, privacy walls, and built-in seating. Whether you want something simple or stunning, we’ll design a deck that feels like it’s always been part of your home.

Built Right, From the First Post

What Sets Our Decks Apart

Every custom deck we build begins with a strong foundation—both in planning and materials. Vermont’s terrain and weather demand precise design: from frost-depth footings to water-resistant framing. We consider how your deck will flow with your house, yard, and lifestyle. Then we choose materials that look great and hold up year after year. With Alliance, you get more than a beautiful design—you get a structure engineered to last.

Precision Deck Planning with You in Mind

Good design is about more than looks. It’s about function, comfort, and safety. We plan your deck around how you actually use the space—grilling zones, traffic flow, furniture layout, sun exposure, and views. We’ll help you choose shapes, step locations, railing styles, and underdeck options that bring out the best in your outdoor space. If your property is sloped or limited, we’ll engineer the best way to maximize square footage and structural integrity.

Material Choices That Match Your Vision

Wood, Composite, or Hybrid—We Build It All

Our custom decks come in all materials—from classic cedar to modern composite. Prefer natural wood? We offer cedar and pressure-treated builds with hand-picked boards and protective sealing. Want low-maintenance? We’re certified installers of TimberTech, Trex, and other top composite brands. Not sure yet? We’ll walk you through the pros and cons of each and even blend materials to suit your budget and style. Every deck is finished to match your home’s architecture and outdoor use.
