If you open your garage manually, you don’t need sensors. If you have an automatic garage door opener, sensors are required by law. The federal law UL 325 mandates that all residential garage door openers in the U.S. must include sensors. Designed to prevent accidents and reduce the risk of entrapment, the sensors should be able to reverse the motion of the garage door within two seconds of detecting an obstruction. The sensors are there to keep you, your family, and your belongings safe from a door that might otherwise come down too hard or too fast.

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.

With the exception of small, lightweight torsion-spring garage doors, which can operate with one spring, most garage doors require two springs to work properly. Garage doors with extension springs always require two springs—if one extension spring is broken or otherwise failing, the garage door may open unevenly and could pose a hazard if the remaining spring fails.

Yes, you can pressure wash epoxy floors, but you must take precautions to avoid damaging the surface. While most epoxy floors can be cleaned with a mop, you might choose to pressure wash if the floor is stained, has ground-in dirt, or is covered with mold or mildew. To do so safely, first soak any stains or dirty areas with a gentle cleanser. Use a lower pressure setting with a gentle nozzle, such as a green, white, or black tip, or a 45-degree angled tip. Keep the spray nozzle at least 18 inches away from the floor to protect the surface. Using a surface cleaner attachment or a rotary scrubber can also help prevent overspray. Be cautious if using a power washer that heats the water, as the combination of heat and pressure may be too powerful and could damage the epoxy coating.
