I was looking for Window replacement in Northbrook IL. I called 3 companies, Renewal by Andersen, Pella and Friendly Windows. After meeting with all 3, Friendly Windows was the best choice for my family. Salesman was super knowledgeable and helpful. Didn’t rush to to close the sale like the rest. We ended up choosing Friendly Windows and they provided us with Marvin Windows. We ended up saving an average $10,000 for a Better quality window than the competition. We just booked our order for 25 Marvin Windows. We are excited and cannot wait for the work to be done. We highly recommend Friendly Windows. You get a family owned experience. Thank you for your professionalism and treating our family with respect.
