Unprofessional, Did not respect the contract one year warranty. Fred Kabalawi installed two garage doors for my apartment building. He attached the heavy sheet metal garage door to the hinge that is loaded with two big springs with sheet metal screws. Two months later the screws stripped off the sheet metal door and broke the hinge. As a mechanical engineer for 20 years a rule of thumb when designing a screw the thread's depth for a screw should be equal to 1 1/2 times the screw diameter, when attaching a sheet metal door to a hinge it is recommended to use bolt and nut. Fred came out to check the broken hinge and we found the screws that were supposed to be attaching the hinge to the door stripped off the door and falling on the floor. As a result to this, the hinge broke. He then told me that he would bring a new hinge to fix the garage door. After a week, I called him to see when he planned on coming but he ignored all my calls and messages. The garage door had not been fixed for two weeks so I had to hire someone else to install a new hinge. Fred did not do a good job in installing my garage door and did not respect the contract one year warranty that he signed. If you are considering on hiring him, I recommend looking for someone else.
