While you can technically use WD-40 to lube a garage door, it is not the best option since the oil it leaves behind can attract dirt. Instead, go to the hardware store and locate a lithium- or silicone- based garage grease. You can also search for garage door lubricant online; just make sure you get one that is made with lithium or silicone.

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.

You can expect your seal to last anywhere from 1 to 5 years. Several factors affect this—material, frequency of use, and the weather. For example, seals made from high-quality rubber are built to withstand the elements and can go the distance with a little TLC. If your door sees a lot of action or faces extreme heat or cold, the seal could wear out more quickly. Regular maintenance—like cleaning and lubrication—can make your seal last longer. And while it’s rare, a professionally installed seal on a smooth floor can potentially last up to 10 years.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.
