Colorado's Custom Deck Builder for Homes That Live Outside
It is a Saturday morning in Castle Pines. You step out with coffee and the boards flex, splinter, and show every hard Colorado season.
Now picture an ALTA-built deck: cool composite boards, a raised dinner level, a lower hot tub platform, step lighting, dry storage, and engineering that feels like part of the house.

Why Colorado Homeowners Choose ALTA to Build Their Deck
Most decks in Colorado fail early for predictable reasons. Many builders frame with the cheapest lumber, set footings too shallow, and the ground heaves the first hard freeze. Surface boards bake under high-altitude UV, then crack and splinter.
ALTA Outdoor Living builds the opposite way. We frame with steel and premium treated lumber that resists warping and rot. We anchor on helical piers that hold firm through freeze and thaw. We surface with capped composite engineered to shrug off altitude UV and hold its color for decades.
Every span, footing, and connection is detailed to pass Colorado inspection the first time. You get a deck that still looks new long after a kit deck would have been torn out.

Engineered for Colorado's Toughest Conditions
Front Range weather is hard on outdoor structures. Altitude drives UV intensity up. The ground freezes and thaws on repeat. Summer afternoons swing 40 degrees in a few hours. We have torn out too many decks that warped, heaved, or rotted inside a few seasons. We build so that does not happen to yours.
- Steel and Treated-Lumber Framing Fortress steel, ProWood pressure-treated, PWT, and KDAT lumber that resist warping and rot.
- Helical Pier Footings deep, ground-anchored footings that hold steady when the soil freezes.
- Capped Composite Surfaces boards from Trex, TimberTech by AZEK, Fiberon, Deckorators, and Barrette that hold color and stay splinter-free at altitude.
- Underdeck Drainage panel and gutter systems that turn the space below an elevated deck into a dry, usable room.
- Code-Ready Engineering spans, framing, and footings detailed to clear Colorado inspections the first time.

What Colorado Homeowners Say About ALTA Outdoor Living
The Complete ALTA Decking Lineup
ALTA Outdoor Living designs and builds in every major decking material and structure, each one matched to your budget, your site, and how you want to use the space.
Composite Decking
Capped composite from Trex, TimberTech by AZEK, Fiberon, Deckorators, and Barrette Outdoor Living resists fading, staining, and scratching while giving you the look of wood and a weekend back.
Premium IPE Hardwood
This dense tropical hardwood naturally resists rot, insects, and fire. It is the premium natural-wood choice for architectural homes and decks meant to last decades.
Deck Framing
We build on Fortress steel framing for spans that never warp, and on ProWood pressure-treated, PWT, and KDAT lumber where wood framing fits the project. Strong bones under the surface keep the whole deck flat and solid for the life of the build.
Footings and Foundations
We anchor most Colorado decks on helical piers, which screw deep into stable soil and resist the heaving that wrecks shallow footings every freeze. Where the site favors it, we set traditional concrete footings.
Underdeck Living Systems
We install panel-based, gutter-and-channel, and custom-fabricated underdeck systems that keep the area dry, then finish it as an outdoor living room, a storage zone, or an entertainment hub.
Deck Skirting
We close the gap between deck and ground with clean horizontal or vertical board skirting and low-maintenance composite skirting. It finishes the look, blocks pests, and keeps the under-deck tidy.
Deck styles
Deck Styles We Design and Build
Whatever your home and lot call for, ALTA Outdoor Living has built it across the Front Range. We match the structure to the view, grade, door height, and daily rhythm of the house.

- Raised Decks elevated decks that meet a second-story door or a sloped lot.
- Multi-Level Decks stepped decks for dining, lounging, and hot tub zones.
- Freestanding Decks standalone decks placed anywhere in the yard.
- Rooftop Decks usable outdoor space built over a roof, garage, or addition.
- Pool and Spa Decks slip-aware surfaces built around pools and hot tubs.
- Cantilevered Decks decks that extend past their supports for a clean, floating edge.
- Screened and Covered Decks roof, screen wall, or privacy screen options for season-long comfort.

Our Process
From First Call to Final Inspection
Most homeowners have never commissioned a custom deck. We built our process to remove every unknown.
Free Discovery Call (Day 1)
A short conversation about your space, your slope, your view, and what you want the deck to do. No pressure and no quote yet. Just a clear read on fit.
In-Home Consultation and 3D Design (Week 1)
Our specialist visits, measures the space, studies your sun, wind, and grade, and walks you through materials, styles, and railing. Then we render your deck in 3D so you see it before we build it.
Detailed Proposal and Permits (Week 1 to 2)
A full materials breakdown, transparent pricing, and a fixed timeline. We pull every permit and handle the inspection paperwork so you never chase the county.
Material Order and Fabrication (Week 2 to 4)
We order your composite or hardwood, steel or lumber framing, and footings, then stage everything for a clean, fast build.
Construction and Installation (On-Site)
Our crew sets the footings, frames the structure, lays the surface, builds the railing, and wires the lighting. Clean job site, careful around your landscaping, polite in your home.
Final Walkthrough and Inspection (Final Day)
We pass the inspection, walk you through care and warranty, and hand you a finished deck. Every ALTA Outdoor Living client gets a first-year check-in.
Take the Deck Further
A deck is the foundation. We extend it with the structures and details that make a yard feel like another wing of the house.
- Covered Roofs solid shingle roofs that keep sun and weather off the deck.
- Pergolas open or louvered overhead structures for shade and definition.
- Privacy Screens panels and screen walls that block sightlines and wind.
- Built-In Lighting step and rail lighting wired in for safe, warm evenings.
