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 of Berkeley, from the iconic Campanile at UC Berkeley to the Berkeley Marina, with their Craftsman houses by Elmwood up to the Northbrae bungalows, have a long architectural tradition. However, old houses are especially susceptible to the foundation movement due to age, the nature of soil and hilly landscape of the area. The soil in the area is rich in clay, which swells whenever it gets wet and shrinks whenever it gets dry and it slowly moves structures constructed decades ago on thin foundations. Fine cracks in the plaster walls, unhappy floors, or recalcitrant windows, are likely indicators of this gradual but consistent creep of the walls below the surface.
The foundation repair and stabilization services offered by us are specific to both the historic and modern homes of Berkeley. We tighten aging foundations, support sinking foundations, and provide permanent stability to them- but without altering the look or charm of your property with precision-engineered push pier systems. Our solutions are a combination of knowledge in engineering and respect to the unique architecture of Berkeley, regardless of whether your house is located close to Tilden Park or downtown.
Berkeley is as eclectic in her soils as in her architecture. Most of the neighborhoods are constructed on huge amounts of clay that are extremely sensitive to the variations in moisture and the others are constructed on hilly lots where the ground erosion and gravity progressively take the land down the hill. All these coupled with years of natural settling, means that foundation instability is a frequent problem – especially in older houses.
We carry out elaborate soil and structural analyses prior to the commencement of any project. Through becoming aware of the areas of weakness and establishment of the depth of stable soil, we will guarantee that all push pier installations are deep and long-lasting. It ends up producing a foundation that can support the complicated soil behavior of the city of Berkeley over the generations to come.
The concept of push piers is that the weight of your home on the unstable surface piers can be assigned to deeper strata that are underneath and can reach deep strata that are load bearing. The solution can even reverse years of movement, especially in Berkeley where movement is necessitated by the difficult terrain.
Push piers reinforce the foundation at its lowest levels to extend the life of your structure and maintain the comfort and safety of your house.
In case you are noticing cracks, sloping floors, or space around door and windows, then the point is not to panic, it is to take action. The problems in the foundation that have caused issues in the past will be less costly and easier to fix as long as earlier they have been addressed.
Our foundation stabilization process will start with the thorough inspection process that will be followed by the elaborated plan of the quantity of piers required, their locations and approximate cost of repair. We maintain a level of communication with you throughout the process and make sure that you know what to expect at each stage. Using the push pier technology, the homeowners are able to no longer worry about the constant settlement and begin to think about the security and comfort of their homes.
We’re here to help! Swiftly addressing these concerns is key. Our experts will promptly inspect and repair your foundation, ensuring the lasting strength and safety of your home. Reach out without hesitation for reliable assistance.
