Unfortunately, theft is one of the biggest fears of homeowners and garages are typically an easy target as they are usually less secure. Due to the nature of garages they will most likely be holding items of value so it is in your best interest to ensure that your garage is secure and one way to do this is having a quality garage door.
Side-hinged doors are a firm favourite as far as security, aesthetics and durability. You can secure them with extra locks due to the way they open and you do not have to have the whole door open when is use, potentially revealing the contents to passers-by.
Sectional garage doors are quite reliable and sturdy, offering high security and even can be electronically operated. They can be quite convenient as they roll up and out of the way along the ceiling, which keeps them out of the way when open and offer few weak points for potential burglars.
Whatever the choice, ensuring the door is make of good quality materials, has serviceable locking mechanisms and is maintained well, will reduce the chances of it being a weakness to theft. Motion sensing lights or a security system are extra security and a helpful theft deterrent.
