"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

We offer free inspections to homeowners looking to sell or potential homebuyers. We also are opening our new office in Riverside. Call today!

"We hired Professional Foundation Repairs (Ozzy and Darin) during our home purchase after they identified foundation/leveling issues. After the work was completed the leveling showed little improvement and they told us the contract ?wasn?t specific enough.? Four years later three different foundation companies inspected the house and found multiple areas where the previous repairs are failing and large visible sections (including the entire front of the house) were never brought up to code or properly retrofitted. I contacted Ozzy and was initially told Darin would cover the corrective work (there are text messages confirming this), but the company then stopped returning calls and messages. Darin (the owner) has not returned my calls. I have inspection reports, photos of the deteriorated repairs, and our text messages documenting their agreement. Their advertised 10-year warranty proved meaningless in practice. Bottom line: poor workmanship, broken promises, and no aftercare. I canno"

They even fixed a soft spot in our wood floors and did an incredible job. Highly recommend this company!"

Earthquake Retrofitting questions, answered by experts

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.

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.

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.

An earthquake retrofit is essential for safety in an earthquake-prone area. Without proper retrofitting, your home is at risk of sliding off the foundation, shifting, or collapsing.

You may also require a retrofit if your home was built before 1980 when building codes began requiring reinforcing, bracing, and bolting for new construction. You may not be eligible for insurance to help pay for earthquake-related damages without a retrofit.

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.
