Sectional doors might be manual but in more cases than not, they are operated electrically. This means they can be operated using a switch or button, Wi Fi, or a remote control, so in some cases, you can control a sectional garage door from anywhere, depending on the option you choose. All sectional doors will be very well engineered and very reliable, whether they are manual or electric, but there are arguably more benefits available with an electric door.
If you opt for an automatic sectional door have it installed by someone who is qualified to work with electricity. Not only will this be safer, it will also be better for the longevity of the door and will ensure that it is reliable, opening and closing with a smooth and rapid motion. Manual doors are possible to install yourself but will still benefit from professional installation for the best possible fit and optimum security.
