Alta Outdoor Living Explains Why Sedalia, CO's Dry, High-Altitude Climate Creates Specific Cracking Risks for Composite Decks That Most Property Owners Do Not Expect
Sedalia, CO — Alta Outdoor Living, a family-owned outdoor construction company with over 30 years in business, more than 1,000 projects completed, and a portfolio of award-winning designs, is releasing guidance to help Sedalia, CO property owners understand how dry climate conditions affect composite decks and what product selection, installation details, and framing decisions protect against the deterioration that high-altitude thermal cycling drives over time. Composite decking is one of the most durable options available, but durability in one climate does not automatically transfer to another, and the dry conditions that define Sedalia, CO create a specific set of stressors that property owners need to understand.
Dry, High-Altitude Climates Stress Composite Decking Differently Than Humid Ones
Most composite deck problems discussed in the industry center on moisture and humidity. Sedalia, CO presents the opposite challenge. In a dry, high-altitude environment, composite decking boards face significant temperature swings between daytime highs and nighttime lows, particularly through the transitional seasons. These thermal swings cause boards to expand and contract repeatedly in a short time frame. Without proper installation gaps that account for this movement, boards push against one another and develop surface stress that leads to cracking, buckling, or surface delamination over time.
UV intensity at elevation compounds the problem by degrading the protective outer layer of composite boards faster than at lower altitudes, reducing the material’s ability to manage thermal movement as effectively as it did when new.
Two Cracking Patterns Are Most Common in Sedalia, CO Conditions
Surface crazing appears as a network of fine cracks across the board face and typically results from prolonged UV exposure breaking down the cap layer of the composite board. Once that protective layer is compromised, the board’s core material is exposed to the same dry conditions and temperature cycling that caused the surface damage, and deterioration accelerates from that point forward.
End cracking is the second common pattern and occurs when boards are not cut and installed with adequate end gap allowances. In a dry climate where thermal contraction during cold nights is significant, boards installed without sufficient end clearance develop tension at the cut ends that the material cannot accommodate without cracking. This is an installation detail that matters enormously in the Sedalia, CO environment and one that Alta Outdoor Living addresses as a standard part of every composite deck build.
Product Selection Within the Composite Category Has Real Consequences Here
Alta Outdoor Living works with composite decking from Trex, TimberTech by Azek, Fiberon, Barrette Outdoor Living, and Deckorators, and advises that not all composite products perform equally in a dry climate. Fully capped composite products, where a protective polymer shell completely encases the board core, offer significantly stronger UV and moisture resistance than partially capped or uncapped alternatives. In a high-UV environment like Sedalia, CO, the difference in cap quality between product lines translates directly into how long the board surface retains its protective integrity against the thermal cycling and sun exposure the local climate delivers consistently.
Alta Outdoor Living incorporates 3D deck modeling into every design consultation so that property owners can review the full scope of their deck system, including material selection and board layout, before construction begins. Permit acquisition and full foundation installation using helical piers or traditional concrete footings are handled as part of every build.
The Substructure Affects How Well Surface Boards Handle Thermal Movement
A framing system that maintains its dimensional stability through temperature swings supports the composite surface above it more consistently, reducing the board movement that contributes to joint and surface stress over time. Alta Outdoor Living builds with wood framing, steel framing from Fortress Building Products, and pressure treated LVL options including PWT lumber and KDAT lumber, providing a range of framing systems suited to the structural demands of Sedalia, CO builds.
What Alta Outdoor Living Backs Every Project With
Alta Outdoor Living provides a 5-year workmanship warranty and material warranties of up to 50 years on every composite deck project. Financing is available for qualifying projects and free estimates are the starting point for every new build, deck remodeling, deck addition, or resurfacing project.
