Deck Builders in Broomfield, CO — Composite Decks, Pergolas & Patio Covers
Looking for a deck contractor in Broomfield? We design and build composite decks, pergolas and patio covers — engineered for Colorado snow load, permitted through the City and County of Broomfield, and submitted for HOA review before a board is ordered.
Quick Answer: Who Builds Decks in Broomfield, CO?
Northern Lights Exteriors has been building decks in Broomfield since 2001.
We are a Class C General Contractor — not a deck-only outfit — which
matters more on a deck than on almost any other exterior job, because a deck ledger bolts
directly through your siding and into the structure of the house. When that connection is wrong,
the problem is not the deck. It is water in the wall. We can open the siding, correct the
flashing, and close it back up under one licensed contractor.
We build composite decks (Trex®, TimberTech®, Deckorators®), plus
pergolas and patio covers
— across Broomfield 80020, 80021 and 80023, including Anthem, Broadlands, Interlocken,
McKay Landing, Willow Run and Wildgrass. We also handle deck repair, deck restoration
and full deck replacement when an existing structure is worth saving — and we
will tell you honestly when it is not.

Your Price, Decided With You — Not a Surprise Quoted Price Later
The worst part of most deck projects is the gap. You spend an hour describing what you want, someone measures, everyone leaves — and days later a number lands that you either swallow or argue with. If it comes in high, you start over. We took the gap out.
① Watch the price move while you decide
On the first visit we walk your foundation, structure, decking and finish options together on software we built ourselves. Change the framing, change the boards, change the railing — the price updates in front of you, in real time. You are not waiting days to find out what your decisions cost.
② Build to your number, in the same sitting
Tell us what you want to spend and we work toward it while we are standing on the site with you, instead of mailing a proposal that misses by twenty percent and starting again. Every option is priced as you consider it, so the budget conversation happens with you rather than to you.
③ Find out what you can actually live without
When every change is priced the moment you make it, the trade-offs get obvious fast. Most people end up cutting one thing they were sure they wanted, and protecting one thing they had not realized mattered to them. That only happens when you can see it.
④ This is our own technology
Not a catalog and not an off-the-shelf calculator. We built it because deck pricing genuinely is complicated — footings, framing, spans, rail systems and finishes all move the number differently — and we would rather show you why than ask you to trust a lump sum. You leave the first appointment with the scope of work in hand.
⑤ And no, this is not a high-pressure close
Worth saying plainly, because real-time pricing on a first appointment is exactly what high-pressure home-improvement sales looks like — so the suspicion is fair. We are not doing that. Nobody is going to sit in your kitchen for ninety minutes waiting for a signature, and there is no discount that expires when we walk out the door. This is education: what the options are, what each one costs, and which ones are genuinely worth it on your build. You end up with a project moving at a price you understood from the start — and you decide on your own time.

Building a Deck That Survives a Colorado Winter
Most deck failures on the Front Range are not decking failures. The boards are usually the last
thing to go. What fails is the structure underneath and the connection to the house — and
those are the two things a homeowner cannot see once the deck is finished.
Snow load is a real number, not a vibe
A Broomfield deck has to carry accumulated snow, not just people and furniture. That drives joist
size and spacing, beam sizing and post placement. A deck framed to the minimum for a patio-furniture
load will feel fine in July and sag by March. Wet spring snow is the heaviest load most Front Range
decks ever see, and it arrives after the freeze-thaw cycle has already worked on every connection.
Footings below the frost line
Colorado ground freezes and heaves. Footings that do not reach below frost depth lift, and a deck
that lifts pulls at the ledger, racks the railing, and opens gaps at the house. Doing this correctly
is invisible on the finished deck and is the single biggest difference between a deck that is level
in fifteen years and one that is not.
The ledger and flashing detail
The ledger board bolts through the siding into the rim joist of the house. Done properly it is
flashed so water sheds out and away. Done poorly it is a shelf that holds water against your
sheathing. This is the failure that rots framing behind a wall for years without a visible sign, and
it is exactly where being a general contractor rather than a deck-only builder
changes the outcome — we can open the wall, fix what is behind it, and re-side it.
Which Composite Decking Line Is Right for Your Broomfield Deck?
We install three composite lines, and they are not interchangeable. The right one depends on how
much sun the deck takes, how it drains, and the look you are after.
| Line | Best for | What stands out |
|---|---|---|
| Trex® | The widely recognized choice, broad color range | Capped composite with strong fade and stain resistance, a deep color palette, and the best-known warranty in the category — an easy one to resell if you move. |
| TimberTech® | Premium look, and PVC where you want the top tier | Offers both capped composite and capped PVC. The PVC lines are lighter, exceptionally resistant to moisture and UV, and carry the most realistic woodgrain visuals we install. |
| Deckorators® | Wet, shaded or freeze-thaw exposed decks | Mineral-based composite with very low water absorption and excellent traction — a strong fit for decks that stay damp, sit in shade, or take repeated Colorado freeze-thaw. |
What all three give you
- No staining or sealing cycle — wash it and use it. That is the whole
point, and it is why composite dominates new decks on the Front Range. - Color that holds at altitude — capped surfaces are built for exactly
the high-UV exposure Broomfield gets. - Hidden fastener systems — a clean surface with no screw heads.
- Long manufacturer warranties — typically decades on fade and stain,
backed by our 5-year installation warranty on the workmanship underneath.
We bring samples so you can see color in your own light before anything is ordered —
boards look different on a north-facing deck than they do in a showroom. Compare the lines in more

Pergolas, Patio Covers and Shade in Broomfield
A deck in Broomfield without shade gets used far less than people expect. The sun is intense at
altitude and afternoon exposure on a west-facing deck can make it unusable in exactly the months you
built it for. We design and build the shade structures alongside the deck, not as an afterthought:
- Pergolas — open or louvered, freestanding or attached, sized so the
shade actually lands on the seating area at the hour you use it rather than at noon. - Patio covers — solid roofs for full sun and weather protection, letting
a deck get used in a spring rain or a light snow. - Attached structures — anything fastened to the house is the same
flashing problem as a deck ledger, and gets detailed the same careful way. - Railing and lighting integration — planned with the structure so wiring
is not surface-run afterwards.
An attached pergola or patio cover usually needs its own permit and, in Broomfield’s
covenant-controlled communities, its own architectural review. We handle both. See our
patio cover and covered porch page for
more on structures.
Deck Repair, Restoration and Replacement in Broomfield
Not every tired deck needs to be torn out. What matters is which part is tired.
Worth restoring
- The frame is sound and the boards are not. This is the best case — new
decking and railing on a solid, correctly-footed structure is a fraction of a rebuild, and it is a
common way to put a new composite surface on a deck without starting over. - Surface grime only — boards that look tired but are structurally sound and come back with a proper clean.
- Localised damage — a few bad boards, a failed section of railing, a
loose post connection.
Worth replacing
- Footings have heaved or were never below frost depth. Everything above a
moving foundation keeps moving; you cannot repair your way out of it. - The ledger connection is wrong and there is rot behind it. This is a safety
issue, not a cosmetic one. - Rot in the framing rather than the surface — soft posts at grade, wet
joist ends at the house. - The deck no longer fits how you use the yard. Sometimes the honest answer is
that the structure is fine and the layout is the problem.
We inspect and tell you which one you are actually in, including when the answer is the cheaper
one. A restoration we quote as a restoration is a smaller job than a rebuild, and we would rather do
the right one than the bigger one.
Our Broomfield Deck Build Process
- On-site design conversation — How you actually use the space, where the
sun lands in the afternoon, sight lines, grade, and where the door and the yard want the deck to be. - Material and railing selection — Composite line and color, railing style, lighting, and whether shade needs to be part of the plan.
- HOA architectural review — Prepared and submitted before anything is
ordered, because Anthem, Broadlands, Wildgrass, McKay Landing and Willow Run generally require it. - Permit through the City and County of Broomfield — Broomfield is its own
city and county, so this does not route through Boulder, Adams or Jefferson County. - Footings, frame and ledger — Below frost depth, sized for snow load,
with the ledger flashed properly into the wall assembly. - Decking, railing and finish work — Then final inspection, clean-up, and
your 5-year installation warranty documented and handed over.
