Great experience with Midwest Construction. The bid process was easy and professional. If I were to call the office staff was quick to get me an answer or to call back. I can not say enough about the installation crew! Jim and the gang was professional and personable! Start to finish it was a great experience! THANKS

Wonderful experience from bid to installation! Great crew and professional people. Kept us informed and crew busted their butts in not exactly great weather. Couldn't recommend more!

I had a great experience with Midwest Construction recently when I purchased a new sun room from them. The installer was professional and courteous, and did an excellent and thorough job. I totally love my new sun room and would recommend this company for any work needed.

I highly recommend Midwest Construction for your construction needs. Their service is top notch as well as the quality of their products. They 100% stand behind the work that they do.

We had a great experience with Midwest Construction and plan to use them in the future. We had three windows and a door (became a patio door) replaced due to age. The quote was reduced after a second look was taken, saving us much needed money. The installers were courteous, punctual, and professional, answering any and all questions. We can't wait to have them back to replace the other four windows and siding.

Midwest Construction re-sided our home and put on new gutters. We couldn't be happier with their work. It looks like a brand new home. Everyone we worked with from sales person to installers were so nice and helpful and amazing to work with. If you're looking to update your siding and or gutter call Midwest Construction!

I am so pleased with our new sunroom/deck. The salesman was very helpful and knowledgeable and the project was done before the estimated time. The construction crew did an excellent job, very professional and did an amazing job. The electrician contractor (Action Electric) was also amazing, it was a challenge for them to run wires across a finished basement but when he was done you would never know he was even there. Again I can't express how happy we are with the whole package.

Midwest Construction is very quick to respond to questions. Lee made an extra trip to my house when I had extra questions. Brent also made sure I didn't have any problems or issues during the installation. My windows, bay window, and patio door look great!
