"The installation of our new garage door went perfectly. The team worked efficiently, cleaned up after themselves, and made sure everything looked great. They even showed me how to use the remote properly."

Garage Doors questions, answered by experts

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.

During a garage door tune-up, a pro will check and adjust your door’s components, looking for any damage and loose cables, springs, or rollers. The pro will also lubricate moving parts, like the hinges and rollers, and likely tighten some screws and bolts. They’ll also adjust the door opener’s tension and alignment to make sure it’s level. Finally, they’ll wash the door to ensure it’s clean, and test the auto-reverse mechanism to make sure it’s working as it should.

The best lubricant for garage door components such as hinges and springs is a lithium- or silicone-based lube made specifically for garage doors. You can find this online or at a hardware store for less than $10.

How long garage doors last depends on the type of doors you buy and how well you care for them. But most often, garage doors will last between 15 and 30 years, on average. You can maximize their life span by performing regular maintenance and inspections and repairing problems immediately. A more robust material, like triple-layer steel garage doors, may even last 25 to 30 years with proper care.
