Compromised Garage Firewalls

Can you spot the problem in these garages? 

The garage walls serve as a fire break to slow the spread of fire from the garage to the inhabitable space of a home should a fire break out from paint or gasoline stored in the garage. But many times I see that this firewall has been compromised in one way or another. At a recent inspection, the homeowner had installed a pet door through the wall leading into the garage, which compromised the firewall. At another home, the door from the kitchen to the garage did not close on its own because its 1 spring hinge was not sufficient to close the door by itself. This, too, will compromise the firewall. So will a heating/cooling duct cut into the garage. 

Check your garage walls for your own safety. Or better yet, let Front Porch Inspections check them out for your!
