Windows of Wisconsin

Phenomenal company to work with and very professional installation crew. Whole house replacement windows done in about 2 days even in late December. Installation was carried out in a very professional manner and any time options came up with what we would like they didn’t hesitate to ask and offer their input. Even going so far as to show us what lack of insulation we had before and explaining the newer larger openings to allow for proper foam insulation. A few pieces of siding cracked in the cold but they were quick to get replacement pieces and come back out to fix it.

Our new windows are amazing. From the sales visit to the install, impeccable! Friendly, professional, the house was cleaner after they left than when they arrived. On a scale of 1-10, I give them a 12.

Windows of Wisconsin did a great job replacing our windows! Some of the old windows were 30-40 years old and they made the place look like new again, inside and out! They have a very courteous staff , and did the work in a timely manner. They left the job sight clean. The new windows are good quality and beautiful. We would recommend Windows of Wisconsin to anyone.

We were impressed with their salesman, Marshall. No pressure. He came in, gave us an estimate and said "let me know what you decide". Other salesmen had said "sign now or this price is gone".
Marshall's price was reasonable and considerably less then others.

Luke and Nate did the install. Very professional and knowledgeable. One of our windows was cracked in shipment, so they completed the install, ordered the replacement glass and came back later to replace the broken glass.

Very good quality windows and excellent Customer Service! We would highly recommend Windows of Wisconsin.

Very cordial sales people

Excellent professional service from start to finish. The new window and patio doors look and function great!!! Highly recommend!

Working with Windows of Wisconsin was great. From the estimator, Marshall, office personnel ,Judy to the installers Dave and Rick was wonderful. The finished product turned out beautiful and we have had several compliments!

Love, love, love our new windows at the lake. We had a number of quotes, and decided the pitch from Jamie best met our needs. Emails took place throughout the covid months, keeping us informed as to when our windows were made, and scheduling the install. The install team (Luke and Travis) did a great job, added by Kyle on the second day to do a large lake-view window. Our Marvin Infinity windows make the outside truly look like you can touch it. And the bug screens keep out even the tiniest of flying critters. Love the new look. Our neighbor asked why we got bigger windows and we had to tell her that just the color changed. The new look is fantastic. Thanks Windows of Wisconsin!

Work was done on time, guys did the work efficiently, area was kept clean, had inside and out done in 2 days. Good service from salesman to the installers, so if you're in need of windows, check them out. Price is right, too!

I am very pleased with the Marvin Infinity casement windows from Windows of Wisconsin. The entire experience from the initial meetings with the sales representative to the quotation, ordering, window preparations at their shop (staining/finishing), to the install went very well. All the Windows of Wisconsin staff conducted themselves in a fair, honest, and professional manner and were a pleasure to work with. The installers were very conscientious and put quality as their top priority. Great windows, great organization, great outcome.

See our review on their website.

We met Windows of WI at a home show. There were other vendors that I stopped at, but no other vendor engaged in a conversation with me other than Marshall from Windows of Wisconsin. He answered our questions and we scheduled a consult right away. He came out and provided an estimate and gave us options. He was very honest ,and there was no pressure at all. He is very intelligent and articulate when it came to the product and offered us great advice. When we met him at the showroom, we continued to be impressed with the professionalism and the no pressure approach. We decided to order at that visit and it was the best decision we made. We had our install today. The windows are top quality. I am so happy. The installation crew was very friendly, funny, and very efficient. After they left, there was no indication they were even there. We had decided not do do a few windows...

Patrick was our salesperson. He meet with us twice. Took his time explained our different options for windows and financing. We are having our windows installed in 8-10 weeks. Very happy with the whole process for far. Looking forward to our new windows.

We are repeat customers because their company really offers the best in all categories. If you want security in having the best, this is the company for you.

My wife and I are thrilled with the windows that were installed by Windows of Wisconsin! When we moved into our 90 year old house, that is on the National Historic Registry, it was apparent that the existing windows weren’t going to cut it as they all had putty around the edge of the storm window and frame to keep out the cold. Good luck with that. Also, after replacing 5 storm windows with screens I said to my wife, while on a ladder at the second floor, “we’re done, this isn’t worth it.” I don’t need to suffer a serious injury dealing with out-of-date windows that no longer do their job. When we started looking around the different companies we heard one option was fiberglass. From that moment on we knew what we wanted, they are low maintenance and do not eventually rot. Plus on an old house like ours, they look beautiful as it is not apparent they are fiberglass; they look like...

Honest, great service!!

Loved being able to see the quality of the window we wanted in the display room before we purchased! We love that they listened to what we wanted and we got a great looking bay window for a great price! Everyone from the sales person, office staff and installation crew were friendly and professional! I would definitely recommend them!

Hands down just the most wonderful company to work with! Our salesperson Patrick was very helpful and informative. Paul and the installers did an incredible job making sure our project was even more beautiful then I could have hoped for! Thank You!!!

Great installation, great windows!

Affordable product, fast install and super friendly owner Carl.

WIndows of Wisconsin did a great job installing my new patio door and kitchen window. Very pleased with the whole process from sales to installation to follow up. They are very thorough and professional.

Quality people, quality service, quality products

love our bay window. Great install. Now I need to get another estimate on our other window. Jamie come see me again please

WOW was great to work with. We had three options for the windows and patio door. We were able to stop in the show room and see examples of all three options. All of them looked great. The install went smooth with only one small item missed. Noted the item to Carl and they are taking care of it without any questions. The real mark of a good company is how they handle a problem. Problem could not have been handled any better. Would highly recommend them to anyone who was looking at replacing windows.

I am absolutely thrilled with my new WOW windows! They look awesome, and are so easy to clean! The installation was great and the cleanup very thorough. I will recommend Windows of Wisconsin! Thanks Carl for a great product and professional job!
