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.
Alamo’s quiet residential pockets—set among rolling hills, tree-lined streets, and expansive The quiet residential neighborhoods of Alamo, which are framed by rolling hills, tree-lined roads and large estates, occur on soil that moves significantly over the course of the year. Homes in such regions as Stone Valley, Roundhill, the hillside districts of Las Trampas Ridge are located on the land of a clay nature, which swells and shrinks significantly during rainy winter and hot summer seasons. Uneven pressure Slab foundations in such areas are normally affected by swelling of soil under some regions and shrinking of soil under others.
Houses nearer to Livorno Estates, Danville Boulevard, and to flatter streets near downtown Alamo will generally settle more and over a period of time as the older soil becomes less dense or the water flow patterns changed around the estate. It can be a crack of fine size that runs along a room or a part of the floor, that starts sloping, these are just but a few indications of the soil behavior under the slab. Our crew assesses these conditions and offers repair strategy depending on the terrain of Alamo.
The soil profile of Alamo is mainly composed of expansive clay, which takes in huge quantities of water during wet seasons. The soil as it swells pushes the slab upwards, and as it dries, pushes it downwards, leaving unsupported voids below the foundation. The houses constructed on hilly slopes might also be exposed to downward movement of the soil that strain one side of the slab more than the other.
With time, such cycles cause cracks, misalignment, and uneven interior surfaces. Our crew researches on the dynamics and moisture distributions of soil and the depth of foundation on the areas that require reinforcement the most. We stabilize the weak soil areas and correct the sett of slabs which protects the Alamo homeowners against the structural wear in the long term.
Slab foundation repair is very specific and should be determined by understanding the contact between soil and structural load. The solutions that we provide to the conditions of Alamo are based on modern diagnostics and field experience.
We examine the influences of soil swelling, seasonal dampness and slopeside situations to every slab, and develop corrections based on this information.
Our reinforcements cure uneven settlement, stiffen the slab and give more even loads.
We take the walkthrough with homeowners and present the process of damage and the recovery strategy.
Sunken or uneven floors are an indicator that the slab is losing support in the particular sections. By dealing with such issues at an early stage it is possible to avert bigger structural problems.
Common symptoms include:
We determine the areas of slab which are settling and stiffen them to make them level and stable.
Surface fixes or patching done by the DIY cannot fix under slab movement. Professional repair goes to the root which is a case of soil instability, moisture disequilibrium or lack of sufficient supporting depth. In hilly regions or neighborhoods where there is a lot of clay, it needs to be reinforced with precision in order to avoid the reoccurrence of settlement.
We examine the health of the slab, find out the source of the damage and apply solutions that are meant to support it in the long term.

Yes, slab foundations can be repaired, though the method depends on the type and severity of the damage. Common issues like minor cracks, settling, or heaving are often manageable. For example, small surface cracks can be filled with epoxy or polyurethane injections to prevent moisture intrusion. More significant settling is typically addressed through slab jacking or polyurethane foam injection, which lifts the slab back into position by pumping material beneath it. For structural cracks or severe sinking, underpinning with steel piers may be necessary to transfer the load to stable soil. It is crucial to diagnose the root cause first, as soil movement or drainage problems must be resolved to prevent recurrence. For a deeper look at one specific cause, our internal article titled Can Frost Action Damage Be Repaired? provides expert guidance on this topic.
For foundation repair in Walnut Creek and Contra Costa County, the best time of year is typically late spring through early fall. During these months, the soil is drier and more stable, which allows for a more predictable and effective repair process. Warmer weather also helps concrete and other materials cure properly, ensuring a strong and lasting result. Winter rains can saturate the soil, causing expansion and movement that complicates repairs and can lead to uneven settling. While emergency work can be done year-round, scheduling during the dry season minimizes risks.
