Medium Density Overlay Signs

Medium Density Overlay, commonly known as MDO, is one of the most trusted sign substrates in the industry—and for good reason. MDO panels consist of an exterior-grade plywood core bonded with a weather-resistant resin-impregnated fiber overlay on both faces. This construction produces a sign that is exceptionally smooth, dimensionally stable, and highly resistant to moisture, warping, and delamination. At Big Dog Wraps in Castle Rock, CO, we have been fabricating and installing MDO signs for businesses across the Denver metro area for nearly three decades.

Colorado's Front Range climate presents unique challenges for outdoor signage: intense UV exposure at altitude, wide temperature swings, hail, snow loads, and high winds. MDO is one of the few substrates that consistently performs under these conditions year after year. We finish every MDO sign with premium exterior paints and UV-protective clear coats, then apply digitally printed vinyl graphics using the same 3M and Avery Dennison materials we trust for our vehicle wraps. The result is a sign that looks sharp on day one and continues to perform for years.

Custom storefront signage for businesses in Castle Rock and Denver, CO
Street Presence

Storefront Signage

Your storefront sign is often the very first interaction a potential customer has with your business. It communicates who you are, what you do, and whether you are worth walking through the door. Big Dog Wraps designs and produces custom storefront signage that commands attention and builds trust from the street. Our logo and design team ensures your signage aligns perfectly with your brand identity. We handle the entire process: site survey, design consultation, structural engineering when required, city permitting guidance, fabrication, and professional installation.

Our storefront sign options include flat-mounted MDO panels, dimensional lettering on MDO backer boards, post-and-panel monument signs, hanging blade signs, and oversized fascia signs. Every sign is custom-sized to your storefront architecture and designed to comply with your local municipality’s sign code requirements. We have extensive experience navigating sign permits in Castle Rock, Douglas County, and municipalities throughout the Denver metro area, and we are happy to guide you through the approval process from start to finish.

Accessibility Matters

ADA Compliant Signs

The Americans with Disabilities Act requires specific signage standards for public-facing businesses, and non-compliance can result in costly legal action.

We stay current with ADA signage guidelines and Colorado state amendments to ensure every sign we deliver is fully compliant.

Our ADA sign offerings include room identification signs, restroom signs, exit and stairwell signs, directories, and wayfinding signage systems. We can match your existing brand colors and typography while maintaining the contrast ratios and tactile specifications required by law. Complete your business branding with custom wall wraps and floor wraps for a cohesive interior experience. For businesses completing a new build-out or renovation in Castle Rock or the Denver metro area, we offer comprehensive ADA signage packages that cover your entire facility in a single coordinated order.
