Quality Products and Quality Installation!


Our Founder Said It, We Say It, and Here is What Our Customers Have To Say About Midwest Construction!

We had 11 new windows installed and they all make quite a difference in both appearance and energy efficiency.

My husband says he can now sit in his easy chair and not feel a draft of cold air coming from outside.

We want to thank everyone who was involved in this project for their professionalism and for the quality of their work.

EcoSmart, Double, Single Casement and Awning Windows Installed: Midwest Construction’s crew installed EcoSmart Vinyl Replacement windows using the latest technology to prevent any water or air infiltration.

EcoSmart windows are custom built to fit into the existing opening.  You can change up the style of your windows, like these homeowners did. They went from Double Hung Windows to Casements and Awnings to give the home a more modern appearance.
