Back on February 3rd, I posted a question and received no replies. I am going to re-post this in hopes of a reply. My husband and I want to replace our sliding glass door. The problem is that a concrete porch was poured very close to the house. We have cedar plank siding and plan to cut around the door to get the old one out and get the new one in. Our porch makes it impossible as far as we can tell to cut into our siding at the bottom of the door. How can we remove our old door and install our new one?? Will we have to cut some concrete to do it? Any help or suggestions are greatly appreciated!
