I had a very pleasant experience with Sam from Feldco. He was very helpful and knowledgeable and well spoken. Sam put my mind at ease while I was making the decision of purchasing a new storm door. Thanks again, Sam.

Feldco did an amazing job with my windows!! The entire office from the receptionist to the installers. Everything the sales person told us about Feldco came true. We have noticed that our air conditioner is running less and the noice from the street is much less. If your looking for windows in the quad cities You need Feldco!!! Feldco is a reliable company that dose what they say they are going to do!!

Yesterday morning we had Brandon L here fixing our window. He was professional and on a mission to figure it out. Which he did! He was friendly and clearly understood how to fix windows. We cant thank him enough for his quick, knowledgeable abilities! We would definitely ask for him again if needed.

Javier was absolutely incredible! We had tons of questions and he was very patient and answered them all. He worked with us to find out what we wanted while still staying in budget. Some of the best customer service I've ever received.

I recently purchased a house with a lot of good-sized windows, which seems like a dream until the nightmare of having to update them comes along. After the sticker shock of other window companies' quotes, I discovered Feldco. Andrew came out for a quote and was prompt, friendly, very professional, and a joy to work with. He explained the process and my options very well, and most importantly, he provided a price quote for top-quality windows that was dramatically lower than I expected. I look forward to continuing to work with Andrew and everyone at Feldco.

Very detailed quote process. Austin has great customer service and explained everything clearly. He was very patient with all my questions.

We worked with Joe to furnish our previous house with new windows and were happy to get to work with him again on this house. He was great to work with both times, easily answering my many questions that came up through the process with his obvious expertise in the field. He was willing to create and change our window plan so that we were able to upgrade our home a way we felt comfortable. To top it off, he handled the distaction of my 4 year old and chaotic life with 3 boys with patience and positivity.
