In the cold Midwest winters, having windows that are aging or have cracks not only doesn’t look great, it can cost you much more on keeping your home or business comfortable, and put more wear and tear on your HVAC system. Let Window Doctor replace your windows with high-end, double paned glass windows that are built to keep outside air outside and add beauty to your property.

We offer windows in a wide variety of styles and options for every type of home, and our windows are available in three different types of glass packs: Low-E glass, Energy Guard Low-E, and Thermo-Flect glass that is exclusive to Window Doctor.

Customer Testimonials

I love my new windows definitely will be getting the rest done

The installers showed up on time and introduced themselves. They were very nice to work with and professional. They took some verification measurements and went right to work. They had had all my old windows torn out within an hour and new ones installed and completed within 5 hours of arriving. Very impressed. They also cleaned up after the job and left the house as it was when they got here.

We asked for a quote from the Window Doctor with no intention of buying yet. The quote and value of the windows was unexpectedly better than what we anticipated and we decided to that we couldn't wait. We are happy we moved forward! The windows are great and service & timeliness was as promised. Thank you for a job well done for a great price!

We entered one of those “win a free set of window” things at the fair. Kudos to the guy who said they don’t spam you! They really don’t!Anyway, we let them come do a free consultation, thinking we weren’t going to do anything. At the end of the meeting, we decided to replace our front windows! They were professional, open and honest with us. Very straightforward. They didn’t push us to replace more than we were comfortable with either or sell a bunch of things we didn’t need. If all we wanted to do was one window, they were all for it!There were some scheduling miscommunications, but nothing major. The guys (Jeremiah squared) that did the job were great! Clean and efficient and our windows look awesome! Props to them for not minding that Bluey was on TV😂Very pleased with their professionalism and work! We will definitely be replacing the rest of our windows with them!
