DOORS & MILLWORK
Interior and exterior doors, trim, and custom millwork
MONTANA DOORS & MILLWORK EXPERTS
Western Building Center has served Montana for 80 years, and doors and millwork have been part of the business from the start: the company began in 1946 as Western Woodwork, a cabinet and millwork shop. Today our stores across Montana and Idaho carry interior and exterior doors, moulding, and millwork for homeowners and contractors.
For exterior doors, we carry Therma-Tru steel and fiberglass doors, which are durable, weatherproof, and beautiful. Whether you live in a villa, a log home, or a simple house, Therma-Tru has outside doors to match. Our interior doors come in a wide variety of styles, accessories, colors, and woods.
Western Building Center also offers an extensive selection of millwork and moulding, and some of our close partners include Orepac and Empire Building Materials. Visit your local Western Building Center to discuss your needs with our in-house experts, and ask about special orders for anything not on hand.

Doors Built for Montana Extremes
Montana temperatures swing from -30 degrees in January to 95 degrees in July, and your entry door takes every degree of that punishment. Warping, cracking, and seal failure are common with doors not made for extreme climates. Fiberglass and steel entry doors handle those swings without the upkeep of traditional wood, and Therma-Tru steel and fiberglass doors are durable and weatherproof.
Visit your local Western Building Center to talk through your door project with our in-house experts. We offer scheduled, local delivery to your jobsite, and anything not on hand can be special ordered.
From One Door to a Whole House
Whether you need a single replacement patio door for your Polson lake house or every interior door for a new home in Kalispell, our contractor desk handles special orders for builders and homeowners alike.
As a Do it Best member, Western Building Center offers special order services on more than 67,000 products, so specialty door configurations and millwork profiles are within reach. Bring your plans to any store, and our estimators can include windows, doors, and millwork in your estimate.
Millwork That Matches Montana Architecture
Montana homes range from historic Craftsman bungalows in Butte to modern mountain lodges in Whitefish, and the trim and millwork details give each style its character. Western Building Center offers an extensive selection of millwork and moulding, including baseboard, casing, and crown moulding.
For restoration projects or custom builds that need profiles we do not have in stock, we can special order through our partners. If you bring in a sample, we will work with you to find the best matching fit.

FREQUENTLY ASKED QUESTIONS
What type of entry door is best for Montana weather?
Fiberglass entry doors are the top choice for Montana homes. They resist warping, cracking, and swelling from temperature extremes better than wood, and modern fiberglass doors replicate the look of real wood grain. Steel doors are another excellent option for security and energy efficiency.
Do you offer professional door installation?
We do not offer door installation services. Our team provides expert advice on product selection and special ordering to make sure you get the right door for your project.
Can I order custom-size doors?
Yes. We special order doors in non-standard sizes, configurations, and finishes. Ask your local store for a current lead time on your order.
What brands of entry doors do you carry?
We carry Therma-Tru steel and fiberglass exterior doors, along with Masonite, Simpson, and other door brands. Visit your local store to see what is on hand and compare options.
How do I choose between fiberglass and steel entry doors?
Fiberglass doors offer better insulation and a wood-grain appearance. Steel doors are more affordable and provide superior security. Both perform well in Montana. Our team can help you compare based on your priorities.
What trim and molding profiles do you carry?
Western Building Center offers an extensive selection of millwork and moulding, including baseboard, casing, and crown. Profiles we do not have on hand are available by special order.
