Code of the west

Live each day with courage
Take pride in your work
Always finish what you start
Do what has to be done
Be tough, but fair
When you make a promise, keep it
Ride for the brand
Talk less and say more
Remember that some things aren't for sale
Know where to draw the line


"I wanted to thank you and commend you and your staff/crew for the professionalism you showed during this whole project. Many of our staff and patrons commented at how quiet and efficient you guys were while installing those boilers. So thank you!"

AJ Mock - Buffalo Senior Center
"As a specifying engineer, I have had the privilege of working with GW Mechanical for almost 20 years.  Over that time I have been consistently impressed with the competence of their workforce, their quality of workmanship and attention to detail, and their steadfast commitment to our projects and the building owners, well after construction is complete.  Qualities such as these are increasingly rare; I would endorse GW Mechanical for any commercial project."

Jak Peden Hollinger, P.E.
“GW Mechanical has been the mechanical contractor on several of our projects in Wyoming over the past 10 years. They have consistently demonstrated a high level of integrity, cooperation, knowledge and commitment to the entire team of construction and design professionals and the owner. It is refreshing to work with a firm that embraces a “walk the talk” attitude. We are glad to see them on the list of bidders for any of our projects and are confident that they will help contribute to the projects overall success”.
