Measuring Door Size
Most often when you are doing a door installation Buffalo Grove project, you want to purchase a door that is the exact same size as your old one. Window Door Pro advises you on how to measure the door.
If you increase the size of the opening, you will have to frame the entire opening and it will take much longer to complete the task.
To figure out the size of door you need, measure the width and height of your door, then round up to the nearest whole inch. This will be the size of your door. You may also want to measure from the back of the interior trim to the back of the exterior trim—this is called jamb depth—to know how wide your jambs are.
Once you have measured the interior opening of your doorway, you should measure the exterior opening from the bottom of the sill to the top of its trim. This is to make sure that you don’t leave a gap from a difference in molding after the door installation Buffalo Grove process.
