Problem:
Cannot get a vehicle into the garage because the door opening is too small!

Solution:
A replacement door fitted to the inside face of the garage opening will maximise drivethrough width if your current garage door is installed inbetween the structural opening. A roller or sectional garage door is usually the best option for this purpose as they do not actually travel through the opening when operated so can give you the full structural opening width provided there is a reveal either side(a face to fit to when looking from inside your garage out) and sufficient internal headroom.
If the problem is drivethrough height then a sectional garage door usually gives you the full height of the ordering size if fitted with an electric operator. Side hinged doors obviously give you the full height as well as round the corner doors, particularly the Vertico as it requires very little internal headroom to operate.

Problem:
My garage door is very heavy to open, can I buy a remote control electric operator to help?

Solution:
No!!  Repair or replace the garage door. if the garage door is too heavy, either the springs have worn out and lost their tension or something potentially more serious is wrong such as worn parts in the rollers or the lifting arms. If they were to break during operation the result could be very serious!  A remote control electric operator is not a quick fix solution to a heavy garage door. It will help in the lifting of large garage doors especially one piece up and over doors which require a lot of initial momentum to move but all electric operators have safety systems built in to detect an obstacle when hit. If you fit an electric operator to a badly fitted or worn garage door the safety sensors have to be overriden to prevent false signals being detected by the operator and causing constant auto reverse situations. An electric operator should only be installed to a perfectly balanced garage door whatever the age and model.

Problem:
My vehicle has to be moved back every time to open and close the garage door as our door swings outwards and hits the bumper. Our short driveway means this is a constant problem.

Solution:
Replace the garage door with either a:

Click for link
a/ Sectional garage door
b/ Roller shutter garage door
c/ Round the corner garage door

All the above types of garage doors do not swing out through the opening during the opening or closing cycle which means you can stand or park right up to them and still operate without having to move.
The internal operation is also vertical and straight so if you own a high backed 4x4 vehicle it will not be a problem with closing when the vehicle is inside the garage.

Other benefits from a vertically or horizontally operating garage door include:

Better sealing properties
Better security
Usually very quiet operation
Longer life span
More versatile sizing options
