Replacing a Garage door with a French Door

Hi All,
I will be replacing a garage door with a french door. My question has to do with the cement floor, there is about a 1/4" difference from one side of the opening to the other and I can also see a rise in the middle. I have never installed an exterior door before so I would welcome any advice as to how to deal with the uneven floor. Thanks in advance!


Sincerely,
Cory

The best thing to do is grind the cement and make it straight and level so that you don't have to shim the bottom of the door at all. You can do this with a little 4 1/2" grinder and a diamond wheel. It's not much fun, but it can be done. Just identify the high points with a level and start grinding. Do a little at a time, keep checking with the level so that you don't take out too much at one time.

More or less what sleeper said.

The part the door sill sits on MUST be flat and level. And sometimes the best way to level a garage floor is built a floor over it, with insulation, and staggered 2x4's that level things up. Then raise the door to match the new level.
