Replacement windows

By: on October 04th, 2023 Rating: 5

Happy with our windows so far; we will see what this winter brings. Our salesman, Mike, was awesome. Answered all of our questions we had and followed up with us after the install. The installer laid plastic down inside and outside, cleaned up the mess after the install. We will be recommending to others in town.

We have used Feldco since 1993 or there abouts. We have never had a problem with the product.
Ken is our sale representative now and he is FANTASTIC. Couldn't ask for a better rep.

I called to have my window replaced because it had gas inside. This window was put in twenty one years ago. They are guaranteed for life. Everyone was so kind and helpful. They came today and the two gentleman were so professional. I love my windows and I am so glad we chose Feldco.

Great product and professional staff!

By: on September 25th, 2023 Rating: 5

Back in 2017 we had Feldco replace one window in our home that had broken. They did a great job and the product quality was fantastic. So, now in 2023 when it was time to replace ALL of our windows we called them again. Windows were installed about 4 or 5 weeks after we ordered them. The sales rep who came to our home was very helpful, and theRead More installers worked nonstop for almost 6 hours to get everything done (it even rained on them on and off all day and the never stopped!). They cleaned up after themselves and when they left I couldn't even tell that they had been there, other than the beautiful new windows I was looking at! I highly recommend Feldco!

The process to set up a time for an estimate was easy. Matt was here on time and was really efficient. He walked me through being a first time window buyer, making sure I understood all that he was explaining. Matt was extremely helpful with me when I was deciding on what windows and giving me a budget friendly total. Looking forward to the install andRead More new, efficient windows!

Repairs to 5 year old siding.

By: on August 11th, 2023 Rating: 5

I had some storm damage that required the electricians to remove some of my siding in such a way it was not reparable by them or me. I called Feldco and explained my situation and they had someone out to fix my siding within a couple weeks. I found out from the technician, my particular color of siding was discontinued but he managed to not only findRead More a coil of material to make the repair but also found the caulking in the matching color. The repair is not even noticeable from prior to the damage. I am very happy with the technician Dave who arrived right within the service window and finished promptly and made sure to clean up all the scraps afterwards. Excellent job Feldco!

Outstanding Salesperson

By: on February 13th, 2023 Rating: 5

A week prior to my appointment with Jonathan Rendon, I had an extremely poor experience with a competitor. I warned him of this perception before we met. Then when we did meet I had to kick him out half way thru our discussion because my furnace went out and I had to focus on that problem, He left promptly without any hesitation and that spokeRead More volumes to me about his character and the company. I had him back a week later. The conversation was focused, he took the measurements and offered me an affordable quote which I signed for a new patio door and first floor windows..I would recommend him in a heartbeat to my neighbors and friends that are also looking for similar home improvement projects. Train all your sales staff to act in such a manner and you will do plenty of business in Elk Grove Village.

I just want to say how well I was taken care of by Feldco .This is the second house I have bought windows for from Feldco, The windows I bought for the second house had a problem after a year of installation with air leaks, I called Feldco and they came out within two days, saw the problem and decided the fix would be to replace allRead More the windows. When Bernie and Dave came they spent a lot of time putting them in and explaining what they were doing to fix the problem. They were outstanding workers Feldco should be very proud of them.

Dean from Menasha completed a walk through and did a great job explaining the windows we needed. Nothing hidden behind the scenes when he showed us the cost and what to expect. It was a great presentation and was why we decided to go with your windows. Highly recommend him!
