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!

Between near an exact year ago and now yesterday, we've got (and will have) all windows replaced by Feldco under our professional sales rep Anthony B. He has provided attentive care to our needs and concerns, along with great package deals and costs favorable to our likes and are looking forward to our final installation coming up soon!

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!

I had Feldco install a new front door for my home. The salesman was courteous and professional. I am very pleased with how my door turned out. Would recommend.

Although it took a while for the door (3 months) to be fabricated, as we were told it would. The door was still ready about 3 weeks before we thought.
When it was ready easily scheduled an appointment. The installers showed up on time and it only took a couple of hours. Everything was cleaned up, old door gone, great experience.

I wouldRead More recommend Felco to anyone.

We lost some fascia on the peak of our house because of the recent winds. The crew was very timely in coming out and diligent to get it taken care of. There was a trip charge in this case but we believed it to be reasonable. Thank you!
