FAQ

Outdoor Sign Questions

Do you pull the permits for outdoor signs?

Yes. In-house permitting is part of every outdoor sign project — we handle code research, drawings, and submittals so your sign is installed legally and on schedule.

How long does an outdoor sign take?

Most outdoor signs run about 1–2 weeks from approved design to installation, depending on sign type and municipal permitting.

Which outdoor signs can be illuminated?

Channel letters, cabinet signs, pylon signs, and electronic message centers can all be lit with energy-efficient LEDs so your business reads day and night.

What areas do you install in?

We design, fabricate, and install across Northern Colorado — Fort Collins to Denver, roughly a 40-mile radius of our Longmont shop.

What materials do you build with?

Aluminum, acrylic, polycarbonate, vinyl, and specialty paints — chosen for durability against Colorado sun, wind, and winter.
