Celebrating 50 years and more!

Established in 1965, Front Range Lumber is a full-service lumberyard serving the extended metro Denver area from our locations in Lakewood and Fort Lupton. We’re a family-owned and operated business (now with the third generation coming on) which prides itself on providing excellent customer care and offering the entire range of building materials. We strive to stock a better grade or version of materials to provide a better end result for you.

John Gunzner Award

In 2014, our Founder John E. Gunzner (John Sr.) was named an Honorary Life Member by the Mountain States Lumber and Building Material Dealers Association due to his lifetime contributions to the industry, the community, and our business. This follows up his award in 1983 as the Lumberman of the Year by MSLBMDA (see more below).

After over 54 years of operation in the same location, Front Range Lumber has built numerous long-term relationships with both suppliers and customers alike. Our staff averages over 19 years of experience in the industry and welcomes the opportunity to assist you with each and every project. We offer delivery services – using our own fleet – throughout the area. Most deliveries are completed on a same or next day basis. Trade accounts are offered in order to consolidate billing and payment for contractors.

Pinnacol Assurance Circle of Safety AwardFront Range Lumber is honored to have received Pinnacol Assurance’s Circle of Safety Award in 2016, 2017 and 2019!

This very selective award is given to just a few of their customers in light of their safety record and extensive safety practices. While rules and practices are important, being safe is far more important in both our business and personal lives. We thank all of our staff for doing exactly that!

Congratulations to our very own John Gunzner Jr. He was chosen as Lumberman of the Year by the Mountain States Lumber and Building Material Dealers Association for 2016/2017!

The MSLBMDA is an organization of lumberyards and suppliers throughout CO, WY, NM, and some of Texas, AZ, UT, and NE. The award is given for exemplary work in the industry and the community. Given to people with high ethics and standard, and being a leader in personal, profession and civic life. John Jr was awarded this honor in 2016, following up on John Sr’s award in 1983.

Front Range Lumber’s commitment to quality translates into the highest quality of materials delivered to your job.

The best possible material benefits you by reducing callbacks, warranty problems, appearance complaints, waste and extra time. For example:

  • Kiln-dried after treatment (KDAT) treated lumber – weighs less and is more stable.
  • All of our redwood inventory is “B” grade or above, giving your customer what they really want – a redwood decking board that has few defects like knots and wane.
  • Our framing lumber is mostly #1 or Select Structural grade, lending itself to a better appearance.
  • We carry only the finest quality brands, like ThermaTru doors, James Hardie and Louisiana Pacific sidings, Miratec, Milgard Windows, Stanley, Simpson Strong-Tie, and more.

Front Range Lumber stocks many items generally not stocked elsewhere including fire-rated lumber and plywood, sidings, long length lumber, hardwoods, timbers, treated lumber in all sizes and lengths, microlams in all heights and Baltic Birch plywood.

Trust Front Range Lumber on your next project.

While other suppliers are available to you, Front Range Lumber Company has been here and will continue to be your best source for all your building needs. Whether you are interested in replacing a door, enlarging the bedroom, building a deck, constructing an entire new home, or a large commercial project, you will find everything from framing materials to the final coat of paint at our convenient location.

We hope to see or hear from you soon by personal visit, phone, fax or use our contact form!
