View Our Doors

EXPI-DOOR® Systems Inc. was established in 1999 as an alternative to the existing door suppliers of that time. EXPI-DOOR® determined that there were many builders that wanted a higher grade of materials, quality workmanship, better customer service with more personalized attention, and long term product support.

EXPI-DOOR® operations, sales, and customer service personnel emphasize getting information quickly to the customer, and in an understandable format, to ensure questions are answered and information is complete.

Dunn Building Company

Dunn Building Company

Dunn Building Company, headquartered in Birmingham, AL has a rich history in a multitude of construction aspects from railroad, to road paving, concrete mixing, and general contracting, and they’ve been an EXPI-DOOR customer for about 15 years.

Since 1878, Dunn has maintained a reputation for consistently completing projects on schedule and within budget. Today, more than 70% of their projects are for repeat clients stemming from solid long-term relationships with subcontractors and suppliers. With Design-Build capabilities, Dunn Building Company is able to provide design, engineering, and construction services for their customers. Self-performing on concrete and pre-engineered erection services add a full dimension to their capabilities.

Dunn originally chose (and continues to use) EXPI-DOOR doors because of our ability to produce custom doors and the array of specialty hardware we offer. They prefer our preassembled doors, especially the Series 700, because the Series 700 is a higher-grade door with additional hardware options. However, when they were in need of non-standard-size doors with a removable transom panel and specialty hardware, they knew they could still turn to us for these custom doors.

We are proud to partner with a company that, from turnkey construction to very complicated specialized services for major industrial markets, prides itself on Safety, Quality, and Efficiency at the core of their deliverables. “Do It Right. Consider It Dunn.”
