10-15 Minute Assessment


Like most garages, yours is probably built on a concrete slab. The walls might be insulated, especially walls shared with the house.

It might contain appliances and equipment like a washing machine, water heater, or water softener. Make sure chemicals and fuels are properly sealed and stored at least 3 feet away from these.

If the door has an automatic opener, it should have two safety features: auto-reverse sensors and a manual release cord.

Steps to Assessing Your Garage


Step 1: Check the floor for spalling or cracks larger than 1/8 inch. Repair them ASAP to prevent further damage. Consider resealing the floor every 2-3 years.


Step 2: Look for cracked, buckled, or leaning walls or rafters. Check for water or water stains on the walls or ceiling. Repair leaks ASAP to prevent rot, mold, and damage to your stuff.


Step 3: Check the joints where walls meet floors and seal any gaps. If your garage is insulated, replace loose or missing insulation. At entryways, check weather stripping and door sweeps for gaps.


Step 4: Inspect the garage door and hardware for cracks, dents, or corrosion. The door should open and close smoothly. If it has an automatic opener, test the auto-reverse sensors.


Step 5: Test grounded (GFCI) outlets. Push the “test” button, plug something in to confirm there’s no power, and then press “reset.” For safety, all garage outlets should be GFCI outlets.
