Garage doors serve many functions and over time they can start to wear out. Some parts can be replaced, but if the doors are old and not working properly, it is often better to replace the doors and the hardware at the same time.
If the garage doors are not working at all, you may find that you cannot fix them and installing replacement doors is the best option. The hardware and the door have to be in good working order or the doors can bind or jam when you try and open or close them.
Sometimes the door opener is the problem, so it is important to have that checked if you are having problems with the doors before buying new garage doors and replacing them completely.
Old garage doors often have seals that start to deteriorate over time. Once the seals are old and dried out, air can get in and out around the door frames. If your garage is heated and air conditioned, this can affect the energy bill for your home. Have a technician inspect the door and seals to determine if they can be repaired or if the door needs updating. A replacement garage door is not cheap, but if it saves you money in the long run, it might be work spending the money to replace.
Updated Door Style
The look of your home from the street is important. If the door on your garage is old, has dents and dings in it, or just looks out of place for your home, you might want to replace it simply to update the look of the home. The garage door may not be terribly old, but if you change the look of the home, the garage should probably match the house. New windows, doors, and paint can make the house look great, but don't forget to include the garage in the rehab so it doesn't bring down the look of the home.
Hiring a Professional
If you are going to replace the garage doors on your garage, it is a good idea to call a professional to deal with the garage door installation. There are some parts of the installation that require the installer to use special tools and have a good working knowledge of how the door works. Often, adjustments are required when the door is installed so that it works properly. Most door companies will offer installation when you buy a new door, so ask them about installation options when you start shopping for your new door.
