Ken was very helpful, knowledgeable, and honest.

Fred was a great salesman. He explained about the company, and their promise to their customers. He went through how all installers are trained and that a measuring team will come out before the installation. Broke down the pricing for us and made sure we were comfortable with every detail. He did a great job, and I look forward to working with him and Feldco in the future.

Matthew Amidon

Had Ken out from Feldco for new windows. We did the upstairs a few years ago and and now ready to do the lower level. He was prompt and professional. Did a great job explaining all our options and finding discounts where available. We look forward to having him back for siding in the near future.

Great company to work with. Matt answered all of our questions, explained everything in full detail, and made us very comfortable with our choice of Feldco. Would definitely recommend to anyone!

Great service, communication and awesome windows and siding!

Dustin Mann

Andrew was very knowledgeable about the products and made the process of picking out siding very easy. The program Feldco uses that shows a 3D image of our house with the siding we chose was very helpful to show what the house will look like. The lifetime warranty against hail damage and wind damage also put our minds at ease with choosing to go with Feldco’s product. The siding is high quality, and insulated. My wife and I are very happy with the quality and customer service offered by Feldco!
