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.
The neighborhoods are as diverse as the old Craftsman houses of Elmwood, or the hillside mansions of the overlooking Claremont, its tree-lined streets of North Berkeley, Berkeley all have soil which is moving much more than most houseowners would like it to know. It is formed by the combination of clay-rich soil with steep hills and variable humidity, which forms strong forces under foundations that are older in the city.

The base settlement starts with the soil under a house sliding, compressing, or becoming loose because of wet and dry conditions or inadequate foundation. In Berkeley, the soils are clay-heavy and therefore during the rainy season they swell and during dry months they contract in a cycle thus straining foundations that are old. Even the cracks or the uneven floors also tend to happen in small and this is an indicator that the soil is not sustaining the building evenly anymore.
The foundation can also tilt, sink in places or come off important structural points as they settle. The replacement is required in the case when these problems extend beyond localities. A new engineered foundation replaces load distribution properly, prevents future movement and makes sure that the home will stand decades long.
The structure of commercial buildings in Berkeley has special requirements which are characterized by increased occupancy, increased loads, and strict building requirements. Once a commercial foundation starts to pass, fracture, or become unstable, business functioning and security might be impacted. The replacement of foundation makes sure that the building is still compliant, level and can be used over a long period.
