In most cases the answer is yes. We would still need to asses the suitability of your door as dependant on age and functionality we may advise that it is not a safe option.
If your garage door was manufactured in the last 2 years and is an up and over, sectional or side hinged mechanism then you can almost guarantee it can be made into a remote control operated door. If the door is older then we need to be careful what the manufacturer and model is as there are some doors that simply won operate properly with an electric opener. If you have a regular up and over door and it has the retractable operating gear with tracks running horizontally into the garage then you can buy any number of simple boom type electric operators. These can then be installed with little drama.
If the door is one of the canopy types then you can still achieve electric operation but will require what is known as a bow arm converter which is a metal device that fits to the back of the garage door panel and helps to simulate the twisting action required with a canopy door to
operate properly, all the way up and down.
For any sectional type garage door the addition of an electric operator is very simple, by adding a boom type operator above the door you will be able to operate this door type with ease. Of course as with any of the doors types additional headroom is required to accommodate the electric operator boom and also the motor head section at the back end. Generally to have a modern European manufactured electric operator you will need about 50 mm above the highest point of the top section of the door panel when half opened.
Please never assume that adding an electrical operator to your manually operated door that is already difficult to open or close will be the answer. For an electric operator to work correctly and safely the garage door must be balanced as near to perfect as possible in order for the
safety mechanisms to work properly. If the door is very heavy it is certainly possible to get an electric motor to hoist the door up by overriding the safety cut out but of course the safety will be non existent and the motor will be under undue stress and not last very long at all. An
electric operator is not a substitute for a badly fitted garage door.
