Building Materials & Services

We are a manufacturer, distributor & installer of “Custom-Made Solid Vinyl Welded Replacement Windows”.  We construct MIKRON windows and are manufactured under strict quality control standards from premium grade PVC extrusions.  This extremely durable material is preferred today for many consumer products due to its great strength, low maintenance and excellent weatherability – all in one attractive package!

For 17 years now, we have worked hard at building a reputation as being honest, making great products and for treating their customers well.  Each window is made to fit your present opening and can be installed by our in-house experts.  With the launch of our new website, we hope to extend our service and education about our products and the window industry.  We are also licensed, insured, bonded, and a member of the Cheyenne & Laramie Chamber of Commerce.
