What They Are

Monument signs are ground-mounted, permanent signs — the standard for identifying properties at the road and anchoring your brand at the entrance, day and night.

We fabricate monument signs from aluminum, stone veneer, brick, and acrylic — built to handle Colorado's UV exposure and freeze-thaw cycles. Single-tenant and multi-tenant configurations, illuminated and non-illuminated, designed and installed by our own Longmont team.

FAQ

Monument Sign Questions

How are monument signs installed?

Monument signs are typically mounted to a pipe that is set in a poured concrete foundation for permanence — we manage excavation, footings, and sign installation.

Can a monument sign be illuminated?

Yes. We build internally illuminated faces, push-through acrylic lettering, and monuments with an integrated electronic message center.

What materials do you build monuments from?

Aluminum and ACM, stone or brick veneer, and high-durability paints — chosen to hold up to Colorado sun, wind, and freeze-thaw.

Do you handle the permit?

Yes, in-house. Monument signs often require a site plan and setback review, and we manage the drawings and submittals for you.

How long does a monument sign take?

Typically 8-10 weeks, since foundation work and municipal permitting are involved — sometimes faster depending on your city.
