About

Colorado’s Leading Commercial Glazing Contractor

We specialize in the engineering, fabrication, and installation of architectural aluminum and glass systems for complex, large-scale construction projects. Our partners include general contractors, facility managers, building owners, and public-sector clients who rely on us for unmatched quality, performance, and execution.

With the largest union-trained, OSHA-certified glazier workforce in the state, we have the scalability and skillset to meet aggressive timelines and deliver lasting results even in high-demand environments.

What Sets Us Apart

Scale Without Compromise

The manpower and technical expertise to take on Colorado’s most complex glazing and facade projects — safely, efficiently, and at scale.

Full Building Lifecycle

A dual construction-and-service model that supports clients from installation through repair, renovation, and long-term performance.

Integrity & Professionalism

We do what we say, communicate clearly, and deliver consistent results that build lasting trust and repeat partnerships.

Where Others Hesitate, We Excel

Challenging sites, tight timelines, and unique designs are where Horizon shines. Our people thrive on complexity and deliver where others won’t.

Safety Is How We Get the Hard Jobs Done

Safety isn’t a checkbox at Horizon — it’s the discipline that lets us take on the work others avoid. Hospitals, occupied campuses, airports, high-rise envelopes: the projects that demand the most are exactly where a safety-first culture matters most. Everyone goes home to their family, every day. That’s the standard.

That commitment shows up in the numbers. Horizon maintains an Experience Modification Rate (EMR) of 0.71 — among the lowest in the industry — the result of proactive job-hazard analysis, rigorous training, and crews who hold each other accountable in the field. We pair the highest-quality PPE and equipment with continuous fall-prevention, rigging, and OSHA training so risk is engineered out before work ever begins.

The payoff is more than compliance. When work is done safely, it’s done right — which means it’s done on schedule and on budget. Safety protects our people, our clients’ timelines, and the trust that defines every Horizon relationship.

 Trustindex verifies that the original source of the review is Google. I spoke with Sierra today and she told me they were pretty booked out on their schedule and I wanted something done asap. So she was kind enough to give me two other company recommendations, which I thought was so cool. Top notch customer service with Ridgeline Glass, and if I ever need glass repair in Denver in the future, I will definitely be calling them back. Thank you Sierra!

 Trustindex verifies that the original source of the review is Google. Horizon did a great job in replacing a window.  We had two other companies tell us the individual window in the cluster could not be replaced, but it all needed to be replaced in its entirety. Horizon was able to match the glass and replace just the window we wanted at 1/3 the cost of the entire set.

(Large center window replace in picture).

 Trustindex verifies that the original source of the review is Google. Delivered here and the staff was great to work with. A lot of construction around the area and turns are a little tight if not paying attention when driving a semi truck & trailer.
