LOVE ALL THESE GREAT SUGGESTIONS,! I have set up 3 appointments, but I now have a great list of resources. THANK YOU!! *** 35 year old doors to the back porch just aren’t doing the job anymore! Old glass doesn’t offer any insulation at all! Looking to replace with sliding patio door, preferably Andersen. Floored by a quote from a local company! Please share your experiences. Anyone try Renewal by Andersen? Thanks!
