Our 25-year-old Pella patio sliding door recently failed when moisture intrusion caused the door to swell to the point that it could no longer close properly. The door had a 20-year warranty, so we understood that the warranty period had ended. However, we were disappointed to learn that replacement parts were no longer available for the door and that Pella did not offer us a customer discount that we felt was reasonable toward a replacement. We obtained a replacement quote from Pella, but the cost was substantially higher than what we ultimately paid for Illinois Energy to do the work. Illinois Energy was about half the price for a new patio sliding door. The new door was installed weeks early with excellent service and a lifetime warranty. We are very happy with our decision to go with Illinois Energy. The experience was professional, the price was approximately half of Pella's, and the lifetime warranty gives us much greater peace of mind going forward.
