Wisconsin Building Supply Millwork Shop

Door & Millwork Shop

Our 25,000+ sqft millwork facility is dedicated to producing and providing the finest doors and trim to Wisconsin Builders

Finish off your projects with the finest millwork.

Our expansive Green Bay millwork facility features the best equipment and tooling available to produce and hang over 400 doors a day with an inventory over $750,000 supporting nine locations.

Pre-finishing is done in house with eight standard stain colors and two standard paint colors. Custom stain and paint matching is also available. We offer hand-rubbed gloss finish and a durable water-base formula that helps resist scratches.

All of our products are water based and environmentally friendly. We use a three-coat process that includes a stain, a sealer and a top coat. We also use the latest technology in sanding/denibber equipment. All of this happens within a climate-controlled facility that utilizes a specialized make up air system and a 4-million BTU furnace system.

Interior Millwork

Wisconsin Building Supply also offers licensed fire-rated slabs in 20, 45, 60 and 90 minute doors. We have custom machining for hinging and boring knobs and locks. We buy direct so you'll get the best price available. On large projects we can provide direct to jobsite delivery for purchases larger than 75 units. This will help you save time and money for any project.

Exterior Millwork

For exterior doors we offer Therma-Tru 25 gauge steel insulated slabs. In addition we offer Therma-Tru insulated fiberglass slabs in both textured and smooth skins with a lifetime warranty. This—combined with our ability to pre-finish in any color and provide primed wood jambs that offer six stocked aluminum clad colors—means we can create a custom look and style for any new home building or remodeling without breaking your budget. If needed, we also have licensed fire rating capabilities for our exterior doors and we have the ability to match your exterior door cladding to your garage door frames.

Size isn’t an issue for Wisconsin Building Supply; we will custom cut doors—in both height and width—to help you create the exact opening needed to finish the job.
