I'm thinking about buying a house that has a large window where an exterior door really should be. Assuming I can buy a french door the same width as the window, and I take the window out and cut the rough opening myself, how much would it cost to hire someone to install the doors to meet building codes/etc?

I have a set of French doors installed by the previous owners of my house. It is over a converted patio, so the floor slopes slightly (down towards the doors). The problem is that the doors will only open about 70° before they hit the floor. Are there hinges that are available that would lift the door up as it's opened? Or is there some other solution? I don't want the doors to open outside, and I don't want to have to pull out the door frame. Thanks! The floor is tiled, so I can't grind it down - wouldn't want to anyway; that would make the floor uneven. the doors are steel, so I can't trim them. I found some 'rising butt hinges' online that will solve the problem... thanks anyway.

my front door is great but on the bottom air is getting in so im sure ac is getting out. Also the french doors to my back yard...the lining in between the doors is messed up? Can I fix either of these problems with out replacing the door and french doors?

We have an indoor french door with 3 rows on small windows. Only 1 of those small windows is broken. How do I repair the window without damaging the rest of the door? How do I get the glass back into the door without breaking the rest of the glass? I don't want to have to call the window man or buy a whole new door for 1 small windoe pane if I don't have to. The french door has 15 window panes.
