How many times today have you opened or closed a door? You might not think of it every time it happens, but it probably happened many times. Doors really are underappreciated for all that they do. They provide insulation, privacy and divide your home into different areas for different purposes. While a door might seem like a simple device, there is a lot of force exerted on the hinges and fasteners every time a door swings open or closed. This is why it is so important that your doors were installed properly. A poorly attached door could come loose over time. If it isn’t installed in a square, plumb doorframe, it could scratch your floors up, or it might not seal right. This is why you don’t want to hire your neighbor’s kid to install a new door for you. Instead, you should hire a professional that has the experience to do a good job.
