Trusted Deck Builder for Colorado Backyards
A custom deck built for how you actually live outdoors, from cedar to composite decking.
Lionheart Designz designs and builds decks that hold up to Front Range weather.
Custom deck construction in Longmont and the surrounding Boulder County communities has to account for more than good looks. Freeze-thaw cycles, heavy spring snow loads, and intense summer sun all affect how a deck performs over time, so our team engineers every project around footing depth, ledger attachment, and material choice that actually suits our climate. We plan every backyard deck construction project around Colorado's seasons, giving your home a true outdoor living space to enjoy year-round.
As a hands-on deck builder, we start with your property, not a catalog. We look at grade, sun exposure, drainage, and how the deck will connect to your home before we ever talk materials, and we handle HOA documentation for neighborhoods across Longmont, Erie, Lafayette, and Louisville that require design approval.
Whether you want a simple ground-level platform or a multi-level custom deck with built-in seating and lighting, deck installation is planned to match your home's architecture and your household's daily routine.
Why Choose Us
A well-built deck extends your living space outdoors and gives you a durable, low-fuss place to gather. Deck construction done right also protects your investment for decades instead of years.
How We Build Your Deck
Every backyard deck construction project follows a clear sequence so you always know what happens next. Here's how a typical project moves from first conversation to finished deck.
We walk your property with you, discuss how you plan to use the space, and evaluate grade, drainage, and sun exposure before sketching layout options.
We help you compare cedar decks and composite decking options, finalize the layout, and prepare any HOA paperwork or permits your municipality requires.
Our crew handles footings, framing, decking, stairs, and railings, keeping the site clean and communicating with you throughout the build.
We walk the finished deck with you, check every detail against the original plan, and answer questions about care and long-term maintenance.
What We Offer
Choosing the right custom deck construction team matters as much as choosing the right materials. Here's what our clients across Longmont and Boulder County can expect from Lionheart Designz.
We recommend cedar and composite decking based on your sun exposure, maintenance preferences, and budget, not a one-size-fits-all default.
Our team builds every deck to handle local snow loads and temperature swings, with attention to ledger boards, footings, and fasteners that homeowners rarely see but always benefit from.
You'll know your timeline, your material choices, and your costs before construction begins, with regular updates as the project moves forward.
What We Offer
A custom deck is often the centerpiece of a larger outdoor living space. These related services from our Decks & Outdoor Living team round out the project.
Already have a deck that needs new boards, repaired framing, or a fresh surface? We restore existing structures instead of starting from scratch.
Compare Trex, TimberTech, and cedar decking options side by side to find the material that fits your style and maintenance goals.
Add shade and definition to your new deck with a custom pergola or covered patio structure built to match your home.
Finish your deck with custom railings, code-compliant stairs, or privacy screening for added comfort and safety.
Lionheart Designz builds custom decks for homeowners throughout Longmont and the surrounding Colorado communities. Wherever you're located, our team plans for the same local climate and code considerations.
