"This is THE company to use. I had an old 1907 wooden house sitting on a decaying brick foundation and needing a sister foundation installed and a complete seismic retrofit. Even during the bidding process, Brad from Alpha was extremely attentive without being assertive. I contacted four other companies although one I eliminated since they charged a fee for inspecting. Alpha was very timely with their bid and flexible when I needed help with the budget. All the way through the process, every single person at Alpha was extraordinarily good at customer relations, returned emails immediately, and stayed in constant contact throughout the entire process. Whenever there was a slight change to the original plan due to permitting or a plumbing adjustment, Alpha was very proactive and made sure everything was communicated clearly and promptly. I have really NEVER worked with a company that had such excellent communication skills. This is really one reason I selected them to do the work and, even though they may not have been the least expensive, it is worth the extra price for this reason alone. And Alpha Structural's work speaks for itself as well. Everything was done precisely and well beyond code, an unbid section of foundation was provided under the front porch without increase to the budget, and all materials used were of the highest quality. The project went on somewhat longer than estimated due to permit changes and a short weather delay but was still finished in a timely way. My home is our family's largest asset and it is a great relief to now know it is sitting on a solid foundation. The entire process from first to last was excellent and I cannot say enough good things about the way Alpha Structural handled the project. From the front office to the boots on the ground: A++"

"Ted showed up on the time and date we scheduled. He assessed my home’s foundation and determined that the level of repair needed did not require his company’s intervention. I was extremely impressed with Ted’s honesty and forthrightness. In a world where homeowners are often faced with costly repairs it was refreshing to deal with Ted and by extension Dalinghaus Construction. If in the future I have need of such services I would not hesitate to call upon Ted and Dalinghaus Construction."

"Specialty Design Coatings was very professional, reliable and did a great job in repairing the cracks in our concrete, refinishing, repainting, and resealing our stone. They worked diligently throughout the project, and continuously worked each day. Oscar, the Project Manager, was easy to communicate with and very knowledgeable. The owner also stopped by to ensure everything was going well. The results of their work was outstanding."

"Mario, with EcOrganic Landscape Services (ELOS), was brought in to resolve a difficult situation with our community irrigation system. It was a significant break in the main line underneath a concrete driveway. Previously, this main line was repaired by another company in the same spot. Once Mario analyzed the situation, he determined the root cause of the breaks and provided us with a permanent solution. He replaced the entire pipe under the concrete with a single piece, eliminating all joints under the concrete. He did it in a non-invasive way so that the driveway looks like nothing happened. Furthermore, Mario is very professional and responsible, and he stayed on top of the entire project process, communicating effectively with me and with the homeowner affected by the break. As expected, I have already rehired EOLS to help us with another landscape issue. We highly recommend Mario from EOLS for your irrigation and landscape services. He will do an excellent job for you."

Foundation Repair FAQs, answered by experts

In Orange, habits like frequent overwatering of lawns, letting sprinklers saturate soil near the foundation, and failing to clear gutters can worsen foundation settlement. Planting thirsty trees close to the home or allowing runoff to pool near the slab increases risk. Ignoring small cracks or not maintaining proper soil moisture during dry CA summers can undermine even high-quality foundation repair work over time.

Helpful?

Completing foundation repair in Orange enhances your home’s structural integrity, reducing cracks, uneven floors, and sticking doors. Improved drainage and moisture control help prevent mold and pest issues, while a stable foundation supports efficient HVAC operation and future remodeling. These upgrades not only boost day-to-day comfort but also increase property value and make your home more attractive to potential buyers.

Helpful?

In Orange, homeowners often skip thorough soil testing or neglect to address drainage issues before starting repairs. Hiring contractors without proper foundation inspection experience, failing to obtain required permits, or overlooking HOA guidelines can cause delays. Starting work during the rainy season or not documenting progress can also lead to setbacks, reducing the effectiveness of the foundation repair and increasing future risks.

Helpful?

In Orange, foundation repair can impact plumbing, especially if your home has older pipes that may shift during leveling. Watch for changes in water flow, new leaks, or slow drains. Electrical wiring and HVAC ducts near the foundation may also be affected, leading to uneven heating or flickering lights. If you notice these issues after repairs, it’s wise to schedule a foundation inspection and check related systems.

Helpful?

In Orange, unexpected costs during foundation repair often arise from addressing foundation settlement in areas with clay-rich soil, which may require advanced soil stabilization. Homeowners might also face repairs to older plumbing or electrical lines uncovered during excavation. Additional expenses can include restoring irrigation systems, repairing cracked hardscapes, and ensuring proper drainage upgrades—all of which are crucial for long-term foundation stability and compliance with local inspection requirements.
