The customer service was the best that I have ever had. Amanda was so patient and kind dealing with my condo association that was very demanding. Feldco is the company that stands behind their word. I hope that this company recognizes her and her manager that are exceptional in their job. Thank you so very much for fantastic service.

We bought our Feldco windows in 2005 and just had some windows replaced because of broken seals and screens redone because they were old. Sil was out technician he carefully measured and came back and installed everything. Sil was friendly, knowledgeable and very professional. He did his job with care and made sure everything was cleaned up. It was a pleasure doing business with Feldco again.
