"Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!"

"Mud Worx was AMAZING! Our garage is not incredibly large, but we’re on a hillside and had some super specific requirements about level surfaces for a home gym. Natalia, Frank, and the team offered a fair price, did excellent work, and communicated like professionals throughout. We wouldn’t think twice about hiring them again whenever we have more concrete work!"

"A fantastic experience from start to finish, BGL transformed our vague intentions into concrete form. We needed a soil and grass lawn converted to a rock garden with undemanding but beautiful flora. An adjacent ramp and slab needed to be replaced to correct their inclines. BGL rapidly produced a striking design and then enacted it rapidly and thoroughly. In addition to the concrete work, stone walkways were placed and a drip irrigation system was installed and integrated."

"I recently contracted with Brothers and Brothers Builders to complete renovations on two bathrooms and expansion of the master bedroom walk in closet. This was my second remodeling project having completed a home rebuild a while ago, so I have prior experience working with contractors. Working with Brother and Brother Builders was just a great experience and the finished work is outstanding. Our Project Manager was Daniel Perez who did an excellent job communicating with us on a regular basis, was immediately accessible by text, staying on top of the project, and fulfilling our visions. He is very knowledge and made several suggestions along the way that really enhanced our design. He has a “can do” attitude. Even into the project I would ask him to do little extras and he always accommodated us with a great smile. Daniel even noticed finished items he did not like and had his crew return to redo the work. He was a delight to work with. The on-site managers, Nick and Oner, were also helpful, professional, and very accommodating. In fact, the whole construction crew was great. The project was completed as per the time line and within the contracted amount, no surprises. With regards to the finished product, we could not be happier. Brother and Brother Builders really provide quality work, attention to detail, customer service, stress less remodeling, all in a timely manner. Their quality of work and professionalism is unmatched. Take it from one who has experience with remodeling projects, I highly recommend Brother and Brother Builders."

"The entrance to our house is awkward and we?ve been wanting to change the layout for many years. Matthew provided me with excellent guidance, took the time to make sure I was comfortable with everything, did very high quality work, and finished the project within budget.? It took a little longer than anticipated but this was mostly due to my crippling inability to make decisions.? Everybody that was involved in my remodel was very nice, professional, and such a pleasure to work with.? I am very pleased with the results."

Concrete Leveling FAQs, answered by experts

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.
