They came out for a foundation repair, before the repair they came for an inspection that was free. This is infact an excellent company to work with. The work was done on time and our foundation is now solid and I would highly recommend.
We had an unpermitted sunroom that was improperly supported. Darren was very professional, knowledgeable, and responsive. Ignacio did the work for the project, and he is extremely good at what he does and a very hard worker. I am very happy that at least one of our walls is properly supported by a concrete foundation and our sunroom is properly supported from below.
We got multiple estimates for foundation repair, and this company stood out because they actually took time to educate us on the problem. No pressure, no scare tactics, just straightforward advice and quality work. The repairs were completed faster than expected.
I was nervous buying an older home because of potential foundation issues. Their inspection was incredibly thorough; they used a laser level to document everything and provided a detailed, honest report with no pressure to upsell. It confirmed the house was solid and made me a confident homeowner.
I contacted them for a second opinion after another contractor gave me an extremely expensive estimate. They performed a full foundation inspection and recommended a much more reasonable solution. I’m very happy with both the service and the results.

We hired them for foundation repair after noticing cracks running across our interior walls. The crew arrived on time every day and kept the work area organized. The cracks have stopped spreading and the floors feel level again.
Had these guys over at my mom's for a crawl space repair. Cordination was top notch and they mad sure to excute and complete the job as agreed.
They repaired cracks in my foundation quickly and ensured everything was stable and secure before leaving. The staff was friendly, punctual, and very detail-oriented. I would definitely use their services again.
With its old district such as the Mountain View, Vine Hill and the quaint shopping streets around Downtown Main Street, including landmarks like the John Muir National Historic Site and Martinez Marina, Martinez is characterized by old homes, old apartment houses and ancient commercial buildings. Most of these buildings were constructed at a time when seismic design was nowhere as developed as it is today and the ground floors are open, there are even carports and loose lower levels that can be hazardous during the occurrence of strong earthquakes. The city is perched alongside the influences of active faults and the Contra Costa rolling hills; therefore, the soft-story forms are to be taken into consideration.
Certified soft story retrofitting provides a secure protection option to the owners of the property of Martinez who are willing to maintain the character of their structures, as well as to enhance the structural security. Retrofitting minimizes risk of collapses and improves the performance of buildings through engineered measures that strengthen the lower levels, upgrade load paths and reinforce the weak points. These additions contribute towards making older buildings safe, stable, and ready to withstand the earthquake-like activity prevalent in Northern California.
Retrofitting does not just mean a structural enhancement but rather a life-saving process that would make sure that buildings will stand firmly during an occurrence of a seismic force. Older buildings with open and lower floors fall quite fast and people have to have little time to react. Ground floor reinforcement will help to minimize the danger of the unexpected structural collapse of the building and secure the occupants and emergency workers.
An effective retrofit enhances vertical and lateral load paths and the building can accept and transfer the energy of earthquakes safely. This helps a lot in minimizing the chances of injuries and enables residents to stay put during moderate shaking. Retrofitting is not only a mandatory measure that property owners in Martinez have to complete, but it is also an essential move towards the idea of community safety.
The reason why soft-story buildings do not work is that the lower-story cannot withstand horizontal forces created during an earthquake.
These failures are caused by scientific reasons, as follows:
Through the knowledge of the reasons of these failures, owners can realize the importance of strengthening the lower level in time before the next seismic event. This strengthening is done to make the building act more predictably and shake it harder.
We use retrofit strategy which is long-term performance-oriented and has adequate engineering practices which offer reliable strengthening. The methods and techniques used include installation of steel frame moment frame, reinforcement of the building through increased bracing and shear walls that enable the building to shift in case of any seismic activity without collapsing. These are solutions that are chosen according to the age of the building, its layout and materials which offer maximum protection.
As a technique to adjust the structural balance, reinforcement of the lower level decreases the danger of catastrophic damages. This not only protects the building but also assists the owners to preserve value in their property, prevent expensive emergency repairs and meet changing seismic requirements in the entire Contra Costa County.
