"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 welcome the opportunity to earn your trust and deliver you the best service. No job is too big or too small for our experienced team. Call today for a quote.

"This was my second project with HEXAGON CONSTRUCTION and by far the largest and most complex. (Replacing an old, clay tile roof on a three story house is no job for a rookie.) HEXAGON’s owner, Eli Vatkin, is what everyone should be looking for in a contractor. He’s knowledgeable, reasonably priced, trustworthy, responds promptly to any concerns that you have during the project, keeps you apprised of its progress, finishes on time, and generally aims to please. His contracts were straightforward and “by the book.” On top of that, he’s a genuinely nice guy. Rarely will you find all these qualities in a contractor—and I’ve been around long enough to know. "

We strive to build personal relationships with each of our customers, working with you and not just for you. Safety is always our priority and we continuously work to meet and exceed all regulated safety standards, and our work truly stands the test of time.

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"

Earthquake Retrofitting questions, answered by experts

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.

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.

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.

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.

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.
