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.

The lifespan of garage door springs depends on the type and quality of the springs, the physical environment, and the level of use. In general, properly installed and maintained springs open and close a garage door around 10,000 times . That equates to around seven years if you open and close the door about four times a day. If you use your garage door more frequently, live in a very cold or humid environment that promotes corrosion or rust, or have a very heavy door, your springs may wear out faster and require replacing sooner.

For a garage to be included in a home's official square footage, it must qualify as livable space. This generally means it needs to be attached to the home and have permanent finishings like proper insulation, finished walls and ceilings, and adequate ventilation. To be considered livable year-round, it should also have heating and cooling. The specific legal requirements can vary by location, but if a garage is converted into a finished room meeting these criteria, it may be counted toward the total square footage.
