A canyon-mouth town
Lyons sits where the North and South St. Vrain creeks meet at the base of two canyons — about two thousand people on red-sandstone ground between the plains and the foothills. The setting is the entire point of living here, and it is also the entire engineering brief: sloped lots, wildland-urban interface exposure, and creekside parcels that carry floodplain rules earned the hard way in September 2013, when flooding damaged 128 homes in town and left 88 substantially damaged. Some of those homes were rebuilt elevated. This is a community that builds with its terrain in mind, because it has to.
The new wildfire code — and why we like it
Lyons adopted Wildfire Resiliency Code Requirements effective July 1, 2026, and one provision lands squarely on our trade: the walking surface of a new or replacement deck must meet non-combustibility standards. Conventional untreated wood decking no longer passes; capped composite and mineral-based boards do.
We will be candid about how little this changes for us. On WUI ground we already build ember-aware by default — non-combustible surfaces, framing bays that embers cannot nest in, an underside that is not a woodpile. In Lyons that approach is now simply the code, and we think the town got it right. If you are weighing surfaces anyway, our materials comparison covers the trade-offs honestly.
Building on slope and stone
There are no big master-planned subdivisions here — Lyons is a historic quarry-town core, creekside lots, and foothills custom homes, and almost none of it is flat. A deck on sloped sandstone ground lives or dies on its footings and posts, so we treat the structural work as the project, not the preamble. Elevated decks that put you level with the view, railing systems in slim aluminum or cable that do not fence the view off, and covered outdoor space engineered for canyon-mouth wind rather than catalog conditions.
The material case, beyond the code
Even without the new requirement, this is composite country: full-strength UV at 5,300 feet, hard freeze-thaw swings off the creek bottoms, and hail. Wood on a Lyons deck signs you up for refinishing on a short cycle; composite asks for soap and water. The code and the climate point the same direction.
Repair, replacement, and the honest line
Older decks here get inspected before they get quoted. Sound framing under tired boards can take a re-deck — with a code-aligned surface — for far less than starting over. Failing ledgers, post rot, or footings never sized for the slope make a current-code replacement the honest answer, and we put it in writing either way. Our safety inspection guide shows what we look for.
Permits, licensing, and distance
The Town of Lyons Building Department runs permitting through its Community Core portal and requires a town contractor license — both ours to handle, along with any floodplain review a creekside parcel triggers. From our shop in Centennial Lyons is about fifty-five minutes, the far edge of our range and worth the drive; we regularly work down the road in Longmont and Boulder. Distance shapes scheduling, not price or the guarantee behind the work.
