"The doctor doing the eye exam was very good, but everything else was very bad. The quality of the frames is poor, they break easily. The people helping me select the frames didn't know what they are doing, the frames they recommended for me were too wide for my face and too heavy, they could never get them to fit properly, I finally had to buy a different frame. Even after buying the new frames it took over 8 trips to get them adjusted so they fit well, the regular staff was very bad at doing adjustments, so after the first few trips I realized I had to ask for the specialist and then wait until they were available. The scratch guard that they use, which they charge extra for, doesn't work very well. They charged me for the warranty automatically without asking me if I wanted it and then, when the frames broke within a few months, the "warranty" only covered part of the cost and they tried to get me to pay more to replace the broken frame."

Earthquake Retrofitting questions, answered by experts

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.

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.

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.

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.

Ensure proper ventilation, fix leaks, and schedule regular pest inspections to protect your property.
