"Do not use this company. They will rip you off. The contract was for eight 300W LED 40 ft pole lights, but I caught them redhanded installing 240W. Who does that? Then, they broke my lock and broke into my sprinkler room which I saw on my video which they admitted. Then, Kolb sued me for not paying the bill which I disputed due to lost tools as result of the break-in. Who does that breaking into a customer's sprinkler room and not informing that they did. I had to catch them on my video. Not only that it took over one year to the work proposed work. TOTAL FRAUD. I will be going to court...."

"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

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.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

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.

It is not advisable to try to retrofit your home without the expertise of a professional. These projects usually require a consultation with a structural engineer and a plumber for any gas-related adjustments. Working with a professional earthquake retrofitting contractor is the best way to ensure that any structural work done to your home will help protect you and your family.

Depending on where you live, your insurance company may require you to have a seismic shut-off valve. It depends on local regulations along with the specific provider. If it’s not a requirement, many providers will offer a discount if you install an earthquake valve, which can save you 5% or more. Contact your provider to learn about potential savings for your plan.
