Feldco® has thousands of references available upon request. Here is a sampling from just this past year...

"Thank you. We shopped around for our windows and looked at several competing companies, including some of the very high-end brands. After careful consideration, we felt Feldco offered the best overall quality, appearance and value. When you add your incredible warranty to the mix, you put your offer over the top of all others. How better to back up the claims than with an ironclad warranty? Great idea! Once we selected Feldco, every aspect of the process went flawlessly. After 5 years, I can share that the windows look and operate as beautifully as they did on day one. Our heating and cooling bills all went down immediately. We continue to brag about the windows and the experience to anyone in the market and will do so for years to come. I’m sure you’ll receive several more referrals from us over time. Thanks again for running one of the finest customer-focused businesses I’ve ever come across."

"We are writing to let you know that we were very pleased with the professional job that your salesman did in explaining your product and services to us. His first sales visit to our home was in early July. He gave us a very detailed, technical explanation of your product. He was very knowledgeable and answered all of our questions. In essence, he did a great job. He told us about the company’s history and how they stand behind their product. He was also able to give us a list of references of other homes in our area with Feldco replacement windows. He also advised us of Feldco’s guarantee on the windows. In addition to being knowledgeable about your product he was very punctual and polite, answering all of our questions. Also, the people at your call center have been very efficient and polite when we have called. During the last couple of weeks, we also got quotes from a couple of other window companies. We were not as pleased with other competing companies products, sales presentations or prices. Today, we signed the sales contract with Feldco for the purchase of twenty-three windows. We feel that we have purchased quality windows at a fair price."

"Kudos Kudos Kudos to your salesperson and, subsequently, the installers of my new Feldco windows! My entire experience of ‘taking the leap’ was a delight from start to finish. I want to thank my sales representative for his honesty in his presentation of your product and the choice of selection available to me within my budget. There is no question that his advice and direction was absolutely on target. I am already saving money on the cost of heating my home. Your installers were professional, swift, accommodating, exceptionally clean and respectful of my home. The interior was cleand and debris from the old windows was removed, even thought 11" of snow was on the ground. You made me a believer in truth of advertising. As a senior citizen with a limited budget. I am a very happy consumer."

"I remember seeing you guys on WGN during Cubs games from way back. You’ve been around for a long time. I had a company out to estimate the windows and nobody quite knew how to handle them. Your Feldco rep called someone to get some ideas before he gave me a quote. This is the right way to take care of these. Thank you very much Feldco."

"Every Feldco contact person was helpful and knowledgeable. Each time we spoke to one of your employees we felt more at ease with our choice to use Feldco. Your company has met all of our expectations and then some. I would never hesitate to recommend Feldco. Please pass on our praise. Three cheers to everyone! Job Well done!"

"Our windows & door are just great! The young men that installed them were polite and efficient. We’ve told everyone about you. Thanks to you, our house will be warmer and quieter! Merry Christmas & Happy New Year!"

– P.W., Hammond, IN

"Your salesperson was very informative, polite and did his job very well. Your measurements person came out to our home, while the installations were in progress both days to make sure everything was right. He too was informative, polite and definitely helpful. I guess we are saving the ‘best for the last’! Your two installers that worked at our home last month absolutely amazed us. They worked non-stop. They did not stop for lunch. They did not waste time talking, and best of all their work, the end product, is absolutely flawless. Whatever these two men make as far as salary, I firmly believe they should get a raise!!! Again Feldco…thank you…I will recommend your products and your personnel to everyone/anyone who asks."

"Feldco goes over and beyond to satisfy every customer in many unique ways. They are very dedicated in standing behind their product and installation. Feldco represents what a great window, door and siding company should be."

– M.P., Schiller Park, Illinois

"Just wanted to drop you a quick letter regarding the outstanding service I received on my garage siding and windows from your company. The sales representative that came to the house was knowledgeable and helpful in explaining the different materials and windows and which would best suit our needs. The workers that installed the siding were very professional. They did an excellent job installing the materials and they left the premises as clean as when they arrived. I was also impressed with the phone calls I received prior to installation confirming the date and time and then the follow up call inquiring how I like the siding and windows and if there were any issues regarding the installation. Once again, thank you Feldco for a wonderful job and I would highly recommend your company to others."

"Hi my name is B.G. and about 2 days ago I had Feldco install 17 new replacement windows in our home. We had a crew of 4 guys out there. The main person, Mark, was the one that I mainly worked with while they were at our home, and I just wanted to give a call to say that they were extremely professional, they were extremely efficient, they answered all my questions, they did a great job putting in the new windows and I just wanted to call to say that I was really impressed with Mark and the other three guys he was working with. They all knew what they were doing and they all worked very efficiently, like I said, to get the job done in a timely manner. At the end, when they were going through how the windows worked, with my wife and I, they were extremely patient and really did a great job of explaining all the features and the details of the windows. Just wanted to let you know that, hopefully you can pass this along to them because I think they would really be happy to hear it. Thank you again."

"Feldco’s longevity shows a strong sense of consistency with which they have conducted themselves at a high level of service. Their dedication is exemplified by the integrity with which they conduct themselves."

"Feldco treats each and every customer he way they would want to be treated. The result is a customer first attitude…At every level they are focused on being the very best Window Sales and Installation Company in the United States. It is our opinion that they already are."

– C.S., Chicago, Illinois

"I just want your company to know that customer service on your products is the best. I have never had a problem or concern from my first call to the actual installation."

– P.K., Chicago, Illinois

"Your sales representative was very courteous, polite and quite knowledgeable. Your two installers were courteous and very considerate of our home. They placed numerous drop cloths wherever they were working inside. These two men worked continuously until all work and clean-up was finished. They did not take any lunch and/or coffee break, not even to sit in their truck to warm up (and the outside temperature on date of installation was at the high, maybe, 38 degrees). We most certainly will brag about our experience with Feldco to any people that mention their interest in new replacement windows. Your employees are a credit to your company."

– C.G., Chicago, Illinois

"I just wanted to let you know that the installers who put in our windows were excellent. Jack and the other young man were very courteous, hard working, professional and certainly a credit to your organization."
