Use a black marker to mark the new location for the side of the doorway along the interior of the existing wall.
Making garage door wider.
Install an electric overhead garage door opener with a remote control located at an accessible height for a seated person.
If you are installing a 9 wide door the opening will be 9 3 wide.
One way to do it would be to get wall extensions for the entire the garage and then cut the roof of the garage off lifting it up to the height you want it.
Skylights can provide additional day lighting as a safety factor.
Use an exterior glue if this will be an exterior door.
Frame the rough opening to 3 inches wider than the garage door size you have selected.
To make a door frame wider the do it yourself should also ensure that the planned construction does not cut into any existing electrical or heating and air conditioning equipment.
Step 1 remove the existing door from the frame by unscrewing the screws on the hinges and lifting the door away.
On the non hinge side there may be a bevel which should be removed prior to gluing additional stock.
Frame the rough opening to a height that is 1 5 taller than the door that you have selected.
You also can base the new opening size on the width of the new door you purchase for the garage.
Include motion sensor lighting with the garage door opener as well as on other lights in the garage.
If the door is 7 tall frame the opening 7 1 5.
For example eight feet tall with 4 feet wide are the best solution for one swing door.
If you are widening the door because of a new vehicle widen the door to the equivalent of two additional feet per side of vehicle.
You can start to buy materials after making the plans such as proper lumbers rails and other carpenter stuff.
You re like going to need to remove 1 4 on the hinge side prior to gluing the additional stock.
