"Very poor and unfair inspection. I have water coming into my house due to a contractor putting shorter gutters than what I originally had and the rain diverter is short too. I have water flowing into my house because there is nothing to take the water away. I never had any problems with my leaks in my house until this. The inspector, Robert Push, took pictures of other things other than the cause of the problem. When I pointed to him the evidence of what the cause of the issue showing the water marks streaming down from the roof in between the short gutter and short diverter, he ignored what I showed him and began to find other things to take photos of that had no relation or was even in the vicinity of the problem area to make his report look “professional”. He was hired by the contractor and was biased to what evidence I had. I even had video of that day and told him and he said nothing. The jargon in the report was constantly beating around the bush to what the problem was, saying that I should do a water test and then his conclusion was that it was wind driven rain that caused the problem. How can he make an analysis like that when he performed no tests and was at my house on a sunny day. The day I had the water come in there were no strong winds and I have video proving everything. If you are a contractor that wants to get away with some shady stuff, then these may be the people for you. But their inspection was very unprofessional, poor, and lacked integrity."

Earthquake Retrofitting questions, answered by experts

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.

Costs vary as much as timelines. The average earthquake retrofit costs between $3,500 and $8,700. However, homes on hillsides, large homes, and those with rooms over garages can cost up to $12,000 or more. Make sure to get a few estimates to compare the cost and services.

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.

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.

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.
