The garage door is something that separates the interior of your garage and a way into your home from the outside world. You wouldn’t leave the car parked outside unprotected while you sleep since someone could come around and try to steal it, either with hotwiring if they know how or by just towing it away. You’d be surprised what could happen on the streets while you sleep. That being said, keeping your car safe while you’re unconscious is what a garage and hence, a garage door is for. They act as the first line of defence against intruders in your home and car thieves.
During the day, the car is going to see its most use and that’s why people sometimes leave the car right outside the garage instead of parking it in. It’s a bit cumbersome to be opening and closing the garage door every time you or someone else wants to take the car out and the garage is mostly for storing the car anyways. There are lot of other things you can put your garage to use for and often people leave a lot of things that need safekeeping since they are used occasionally but not often enough to merit being put in the house.
A lot of power tools go in the garage but that’s really just a preference of the residents. Some people use their garage as a place to start a band or to start working on DIY home projects. Spark Garage Doors are of reliable quality and are a great service to consider when you want to either repair or install a garage door in your home as well. It’s better to have one then to have a completely open area that anyone could get into when they want.
