The selection covers main entrances, back doors, patio doors, interior rooms, and house-to-garage entryways.

Our Door Options: Entry, Interior, and New Construction
Every home is different, and so is the right door. Explore the materials and door types we carry, then book a free consultation to compare them in person.

Solid Wood Doors
Timeless elegance and exceptional security in materials like oak and mahogany, customizable with stains or paints to match your home.

Fiberglass Doors
Durable, energy-efficient, and low-maintenance, resistant to warping, cracking, and rotting, an excellent fit for harsh, high-altitude climates.

Steel Doors with Insulated Cores
Built for strength and security. The insulated core holds heat in and cold out, and the door itself lasts.

Sliding Glass & Patio Doors
A seamless indoor-outdoor transition, ruggedly built with advanced locking mechanisms for security.

Interior Doors in Wyoming
We carry interior doors in panel and slab styles, in both solid-core and hollow-core construction. Solid-core doors cut sound between bedrooms, offices, and bathrooms. Hollow-core doors are lighter and work well for closets and utility spaces. Because we also supply cabinetry, we can match your interior door finishes and hardware to your kitchen and vanity lines so the whole house reads as one project.

New Construction Doors
Building rather than replacing? Our new construction doors arrive as pre-hung units sized to your rough openings. We coordinate directly with your builder on framing dimensions and delivery timing, and we can phase deliveries across a multi-unit build so doors arrive as each stage is ready instead of stacking up on site. See our full new construction doors lineup.
Quick Summary: WBS carries entry, interior, patio, and new construction doors in solid wood, fiberglass, steel, and composite, available through five Rocky Mountain showrooms.
Why Customers Choose Our Doors
WBS stays completely accountable for your door installation, from the first measurement through the final seal, so one local company owns the outcome.
Expert Solutions
Fifty years supplying Wyoming homes and job sites means we know how doors behave in this climate, with the right products and installation techniques.
Brands We Stand Behind

Diverse Selection
Whether you want more security, energy efficiency, curb appeal, or all three, we carry an option that fits your home, your climate, and the value you expect.
Quick Summary: WBS maintains full project accountability from the first measurement through the final seal, ensuring correct door alignment and long-term durability.


Professional Door Installation
WBS installs entry doors, interior doors, patio doors, and new construction doors across Wyoming and western South Dakota. We use factory-trained installation specialists, ensuring proper alignment to protect your home's thermal boundary and preserve your manufacturer product warranties.
What Our Installation Includes
Our installation specialists handle the full job: precise measurement, removal and haul-away of your old door, leveling and shimming the new unit, weather sealing, hardware fitting, and a final operation check. We clean the site before we leave. Learn more about our door installation service.

Installation for New Construction and Remodels
For new builds, we coordinate rough-opening dimensions and delivery windows directly with your builder. For remodels, we work around existing trim and framing, and we tell you before we start if we find anything behind the trim that needs repair first. Contractors: we take the design-to-delivery responsibility so you can stay on the build.
Serving Cody, Casper, Cheyenne, Sheridan, and Rapid City
Our installation specialists cover a two-hour radius from each of our five showrooms. That puts most of Wyoming, northern Colorado, southern Montana, and western South Dakota inside our service area. Find your nearest showroom.
Quick Summary: WBS provides full-service door installation from five showrooms, covering measurement, removal, fitting, sealing, and cleanup.

Honest Pricing on Doors, No Surprises
Door project costs are determined by five variables: material choice, glass package, sidelights or transoms, sizing, and installation complexity.
Choosing a new entryway, patio door, or interior door is an investment in your home's value, energy efficiency, and daily comfort. National franchises bury steep overhead inside bundled quotes. Big-box stores leave the installation details up to luck. WBS prices the whole job in the open. Because every entryway in Wyoming has its own dimensions, we do not give generic, one-size-fits-all estimates. You get a fully itemized quote up front that breaks down your exact material choices, hardware, and labor, with none of the add-on fees common at national big-box retailers.
The Five Factors That Drive Door Costs
1. Door material. The foundational material dictates both performance and cost.
- Solid wood (premium oak or mahogany) provides unmatched weight, security, and a classic look, at a higher investment.
- Fiberglass offers superior insulation, extreme weather resistance, and low maintenance at a mid-to-high price point.
- Steel with an insulated core is exceptionally strong and secure, and it delivers the best value per dollar of any exterior material we carry.
- Hollow-core or composite (MDF) options are cost-effective choices for interior utility and bedroom spaces.
2. Glass packages. Standard clear glass is the base. Upgrades to high-performance Low-E glass (UV protection and energy savings), tempered safety glass (impact resistance), or decorative panels add custom value and cost.
3. Sidelights and transoms. Narrow accent windows beside the door (sidelights) or an overhead glass panel (transom) create a grand entrance that floods your foyer with light, but they require extra structural framing and glass.
4. Sizing and customization. Standard sizes such as 80-inch heights are the most cost-effective because they are mass-manufactured. If your home has out-of-square or historical non-standard frames, we can custom-build a door or frame to fit your exact opening, which ensures tight seals and long-term durability.
5. Installation complexity. If our installers find hidden water damage, warped framing, or dry rot behind your existing trim, repairing the framing before hanging the new door adds hours and materials. We tell you before we proceed.

Entry Doors and Door Replacement in Cody, WY
WBS sells and installs entry doors, interior doors, and replacement doors in Cody, Wyoming, from our showroom at 1826 Sheridan Ave.
Cody sits at elevation, with hard sun exposure and real wind. That shows up in doors faster than most homeowners expect. South- and west-facing entries take UV punishment that fades and checks untreated wood. Wind-driven weather finds every gap in a poorly shimmed frame. That is why we usually steer Cody homeowners toward fiberglass for exposed entries and toward Low-E glass packages on anything with significant glazing. If you already know the door is failing, our door replacement team can measure the existing opening and quote the swap.
Our Cody showroom is open Monday through Friday, 8:00 a.m. to 5:00 p.m., or call ahead for an appointment at (307) 578-8228. Free in-home consultations cover Cody and the surrounding Park County and Big Horn Basin communities, including Powell, Meeteetse, and Clark. In-state delivery to Cody is free. Visit our Cody showroom page for directions, hours, and the rest of what we carry locally.
