Custom Pergolas, Built for Colorado.

The Deck Giant team designs and builds custom pergolas throughout the south Denver metro and the foothill communities of Evergreen, Conifer, Morrison, and Golden — attached or freestanding, cedar or treated pine, traditional or modern style, covered or uncovered.

Pergolas are one of Deck Giant's main specialties — not just an afterthought bolted onto a deck build. Our team has built hundreds of pergolas of all shapes and sizes, so whatever your vision, we can bring it to life. Whether you want a shaded spot over an existing patio or a freestanding structure that anchors your whole backyard, we design and build each pergola around your specific needs.

Choose a Style

Modern or Traditional

The two styles look different and support different upgrade options.

Modern style pergola with flush beams and rafters

Two-tone stained, modern-style cedar pergola with privacy wall

MODERN STYLE

Clean, Square Look

Beams and rafters sit flush with each other with no overhang, giving a squared-off, minimal look. Modern is the only style that can take a tongue-and-groove ceiling for a fully finished underside, and it can be built with or without a roof.

Traditional style pergola with overhanging rafter tails

TRADITIONAL STYLE

Overhanging Rafter Tails

Rafters extend past the beam for a classic, layered profile. This style works great with a roof because of the additional overhang and larger coverage area, though it can't support a tongue-and-groove ceiling.

Choose a Material

Cedar or Pressure-Treated Pine

Both hold up in Colorado — the right choice depends on look, maintenance, and budget.

CEDAR

Naturally Beautiful & Weather Resistant

Pros: Naturally resists insects, moisture, and rot, and holds up well through Colorado's swings between dry heat and heavy snow. The rough-sawn texture gives a beautiful rustic look, whether left natural or stained — left unstained, it eventually fades to a silvery grey that a lot of homeowners like.

Cons: Costs more than pressure-treated pine, and it's a somewhat softer wood. Needs to be resealed or restained every few years to keep a like-new finish.

TREATED PINE

Treated for Maximum Rot Resistance

Pros: Won't rot and can last for decades, even with direct ground contact. It's the least expensive lumber option, and it's easy to paint or stain to match any color.

Cons: Boards tend to warp and bend somewhat as they dry out over time. This is usually minimal and not a structural or safety issue — more of an aesthetic one. We recommend larger lumber sizes and more top slats for additional connection points to help minimize it.

Choose Attachment Type

Attached or Freestanding

Both are engineered to hold up — the right choice depends on your layout and how you'll use the space.

ATTACHED

Attached

Connected to your home on one or more sides, using the house for partial support. A natural extension of an existing deck or patio, with a cleaner look and more usable patio space since there are no rear posts — and it avoids posts against the house that could block windows or doors.

Freestanding cedar pergola with custom red stain and cedar privacy wall

Freestanding pergola with 2" spaced top slats, privacy wall, and custom stain color

FREESTANDING

Freestanding

Fully self-supported and placed anywhere in the yard — over a fire pit, a hot tub, or a seating area away from the house. More flexible on placement, with posts and footings engineered to carry the full structure on their own.
