Why Fort Collins Needs Experienced Fireproofing Contractors

Fort Collins and the Northern Colorado region are experiencing some of the most significant commercial construction growth in the state. The city's population has grown steadily over the past decade, and with that growth comes a surge in commercial development that demands professional fire protection services. From new office buildings and mixed-use developments downtown to large-scale industrial and institutional projects on the outskirts, Fort Collins construction sites increasingly require the same caliber of fireproofing contractors that have long served the Denver metro area.

Colorado State University is one of the largest drivers of construction activity in Fort Collins. The university's ongoing campus expansion includes new academic buildings, research laboratories, student housing, and athletic facilities — all of which require code-compliant fire protection on structural steel framing. Institutional projects like these demand experienced fireproofing contractors who understand the strict quality standards and inspection protocols required on university and public-sector work. Andrex Insulation has decades of experience on institutional and educational projects across Colorado, and we bring that same level of precision to every CSU-area project.

Beyond the university, the broader Northern Colorado corridor between Fort Collins, Loveland, Greeley, and Windsor has become one of the fastest-growing commercial construction markets in the Rocky Mountain region. The I-25 corridor connecting Denver to Fort Collins is lined with new development — office parks, medical facilities, retail centers, and distribution warehouses are rising at a pace that has outstripped the availability of qualified specialty subcontractors in the region. This is particularly true for fireproofing, which requires specialized equipment, certified crews, and deep knowledge of UL-classified assemblies and IBC fire rating requirements.

Northern Colorado has also emerged as a hub for data center construction, driven by the region's favorable climate, reliable power infrastructure, and proximity to the Denver tech corridor. Data centers require extensive fireproofing on structural steel to protect the critical infrastructure housed within, and the fire rating requirements on these facilities are often among the most stringent in commercial construction. Andrex crews have experience on data center projects and understand the unique access constraints and scheduling demands these facilities present.

Fort Collins is also home to a thriving brewing and food production industry. Craft breweries, distilleries, and food manufacturing facilities often occupy steel-framed buildings that require fire protection — and many of these businesses choose exposed structural steel as a design element, which means intumescent fireproofing coatings rather than traditional cementitious SFRM. Andrex provides both options, giving Fort Collins building owners and architects the flexibility to meet fire code requirements while preserving the industrial aesthetic that defines the city's character.

What fireproofing services does Andrex provide in Fort Collins?

We provide the full range of commercial fire protection services in Fort Collins: spray-applied fireproofing (SFRM) using BlazeShield II and Monokote products for structural steel protection, intumescent fireproofing coatings for exposed architectural steel, firestopping systems for penetrations and joints in fire-rated assemblies, and spray-applied insulation for thermal and acoustic performance. Every installation is code-compliant and self-tested with calibrated thickness gauges before third-party inspection.

How much does commercial fireproofing cost in Fort Collins?

Fireproofing costs depend on several factors including the total steel tonnage, the required fire rating (1-hour through 4-hour), the specific product specified, project accessibility, and schedule requirements. For Fort Collins projects, mobilization costs are minimal since our crews regularly work in Northern Colorado. We provide free, detailed bids based on your plans and specifications — send us your drawings and we will return a competitive quote with a clear scope of work and timeline.

What types of Fort Collins buildings require fireproofing?

Under the International Building Code adopted by the City of Fort Collins, most commercial steel-framed buildings require passive fire protection on structural members. This includes office buildings, university and institutional facilities, medical buildings, hotels, multi-story residential over commercial, data centers, warehouses, and manufacturing facilities. The specific fire rating required — 1-hour, 2-hour, 3-hour, or 4-hour — depends on the building's construction type and occupancy classification.
