Fifty years of high-altitude installs taught us the precision this climate demands.

Residential Windows
Designed to elevate your living spaces while maximizing thermal performance. Our residential windows blend style and efficiency. They boost curb appeal while advanced glass technology protects your interiors and furnishings from UV fading. That matters whether you are renovating a historic home or building a mountain retreat.
Commercial Windows
Engineered for the demands of high-traffic environments, with a blend of security, functionality, and energy savings. From thermal-break storefronts to expansive office glass, our team customizes solutions that meet strict building codes and enhance the professional feel of any commercial setting.
We also handle phased replacement for multifamily properties, coordinating hundreds of openings around residents and their schedules. Contractors work with us because we own the design, the measurements, and the delivery, so you can stay focused on the build.

Best Window Materials for Wyoming's Climate
Wyoming's temperature swings, high winds, and intense high-altitude sun make material choice critical. Here is how the options we carry compare.
Caption: Not sure which is right for you? We help you decide during a free in-home consultation.
Wyoming can hit 90 degrees in July and drop below zero in January. Every material in your wall expands and contracts through that range, and vinyl moves the most. Fiberglass expands at almost the same rate as the glass it holds, so the seal between frame and pane stays tight for decades instead of loosening into the drafts you feel around an older window. Tight seals are what you actually pay for on your heating bill.
Vinyl is still a strong, honest choice for many homes, and we install plenty of it. But if you plan to stay in your house twenty years, fiberglass is the frame we would put in our own.
For Wyoming's climate, fiberglass offers the best long-term performance and vinyl offers the best value.

From Design to Installation
Step 1
Design
Collaborate with our in-house design specialists and get free 3D renderings to visualize your window layout, styles, frame materials, and glass options, matched to your home's character and needs for natural light, privacy, and airflow. We blueprint the plan and test how it works before you commit a dollar.
Step 2
Select
Explore quality windows from brands we trust for high-altitude performance. We help you compare frame materials (like the stability of fiberglass versus the classic look of wood-clad) and glass packages tailored to your home's solar orientation and your project's priorities.
Step 3
Deliver
Our local logistics team and specialized fleet handle free in-state delivery across Wyoming. Every component arrives on-site in perfect condition and on schedule, from large units to delicate glass. No third-party freight delays. No damage in transit.
Step 4
Install
Our factory-trained crews handle the precise leveling, shimming, and sealing that draft-free performance requires. We treat your property with respect and leave a clean job site.
WBS designs, supplies, delivers, and installs every window, so there is one point of accountability.

Daniel Appel
I want to give a huge shoutout to the crew that installed my windows. They did a fantastic job from start to finish! The team was professional, courteous, and paid great attention to detail throughout the installation process.
I especially appreciated that they took the time to thoroughly clean up after the work was completed and even washed the windows, leaving everything looking spotless. It's clear they take pride in their work and care about customer satisfaction.
I highly recommend your company and crew to anyone looking for quality workmanship and outstanding service. Thank you for such a great experience!
