"This contractor was hired by my 67 year old mother. Contractor was very attentive at first. Paid for 1/2 the project up front. He then started missing a day here or there. Would not return phone calls. Then would just show up one day, work for a few hours thenhen disappear again. Sometimes for weeks at a time. He was to redo my brick fireplace and after the 3rd try, me guessing he had know idea what or how to do what I was wanting and instead of telling me this he just kept getting deeper into trouble. He then asked for additional money for the carpet. I have not heard from him since. A 7-10 day project has turned into 90+ days and it is still not completed. My aluminum outlets were replaced by him with Copper and the special glue that is to go on the wiring was omitted! FIRE HAZARD. He was to hang a ceiling fan and there was no ceiling fan support box installed. It would have fallen if he would have installed. Stay away from this contractor. I have had another contract try and contact him for my carpet that I paid for and he will not return that phone call either."

Earthquake Retrofitting questions, answered by experts

Projects will vary based on size and scope, but an average earthquake retrofit takes between two weeks and two months. This includes the initial evaluation and plan, bidding and contract paperwork, permitting and approval process, actual work, and final inspection. Your contractor should give you a more accurate time estimate for your specific project, and they may be able to estimate how long the permitting process will take for your area.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.

Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.
