We are also happy that we can help you feel good knowing that you are working with a reputable company that stands behind its products and services.

"I hired Secure Seismic to do a retrofit of my single story ranch built in the 1970s. Though I'm in the southern Willamette Valley and a ways from Portland, Daryl came down to give me a free estimate. Secure Seismic came in below their competitors and Daryl discusssd the plan with me in depth. Based upon the quality of the reviews, I hired Secure Seismic. They scheduled out within a couple of weeks. Johny the foreman kept me on the loop while they were at my house. They completed the job within a day and left the site clean. Pieces of drywall cut for access in the garage were thoughtfully replaced and will take little effort to clean up. Thanks for great work! I already sleep a little better knowing that my house will likely be okay when the big one hits."

Sunlight Solar Energy, Inc is committed to providing our Oregon and Washington customers with the highest quality grid-tied solar electric, solar hot water, solar pool, radiant floor, and electric vehicle charging station installations for homes or business. We are proud to be a SunPower Premier Dealer and to offer SunPower components to our customers. Sunlight Solar provides a professional system design and installation experience, complete with excellent communication, and timely follow-up.

"A warning to anyone considering using Sunlight Solar Energy of Bend Oregon. I had a small system installed on my home in Colorado TWO years ago; a location they no longer service. They installed the system on my roof which was 18 years old, and not in the correct condition ( of which I was unaware) to accept panels as the roof was not well ventilated because of short cuts in the building process. The damage was obvious to every single roofing contractor that came to look at it. I could not detect the damage because the pitch of the roof is extreme. After calling several other reputable solar companies, they all made clear it is an industry standard to not install a roof older than 10 years and all companies advise homeowners to have the roof checked first before installing panels. Never once did Ryan Campbell the installer speak to me about the condition of the roof, which had many years worth of damage. His goal was to get the panels up, take my money and disappear. And disappear they did. Ryan's number disconnected, and the Colorado website page for Sunlight has one digit off so that you can't reach anyone that way either. I did however find a way to contact Paul, the president of the company, and ask for help in getting the panels de-installed and reinstalled after the roof gets replaced (on my dime) given they did not discuss the roof with me prior to install. He first agreed to help me by finding a solar company to take the panels down ( a cherry picker is required because it it so steep $$$$$$) and then refused to help at all a few days later. As someone who runs a small business, I am disgusted. I would never treat a customer this way. As a homeowner, and a professor of environmental sociology who professes the value of solar, I am enraged. This company is awful. Steer as far clear of them as you can. There are other companies deserving of your business."

Earthquake Retrofitting questions, answered by experts

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.

Hearing or feeling vibrations in your house can be unsettling, but there are a few possible causes for a vibrating noise in your wall or floor. Light bulbs and fixtures, circuit breakers, loose pipes, or faulty wiring could all cause vibrations. If you’re not sure what’s causing the vibrations, you can call a contractor to assess your home and narrow down the cause.

Some cities or states may require you to have an earthquake gas shut-off valve. Your insurance provider may also have requirements for installing this valve. Even if you don’t have to have one by law, it’s wise to have a natural gas plumber install one anyway. These devices can be lifesaving and prevent fires or explosions in the event of a gas leak.

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.

First, you can expect the project to be loud. If you have pets, you might want to take them to a friend's house during the day so they are not disturbed by any of the loud noises. In addition, you’ll need to provide the retrofit team access to areas of the house that will need to be worked on, meaning you’ll need to relocate personal items, clear clutter, and make pathways for the crew. Once the project is complete, a local building inspector will conduct a final inspection to ensure that the retrofitting is up to code.
