We were on a time constraint which was appreciated. I was sent an inspector by the name of Golan who was knowledgeable , thorough and professional. He came and did the inspection and did a great job of explaining the result of the inspection to me where I could understand it. I would definitely recommend Sunshine Foundation but I would especially recommend Golan to anybody due to his knowledge and efficiency. I was very happy with the inspection and would recommend them to anyone.

Adam visited my property and spent almost an hour mapping out the entire floorplan and created a detailed plan of attack - all free of charge!!! He carefully measured whether the floor was uneven using a laser, took numerous photos of the areas of concern in the crawl space (wearing a full hazmat suit, goggles, and a high-end face mask), and patiently answered all of my questions. I had another vendor visit the property, and he only spent 3 minutes poking his head around - he did not even enter the crawl space! Therefore, it was an easy choice to go with Sunshine. I felt comfortable enough with Adam to ask him to visit my parents' home for a possible retrofit. Unfortunately, this structure does not have a crawl space / cripple walls and thus is not able to be retrofitted. I feel very comfortable in recommending Adam for other projects, and I look forward to engaging with Sunshine again soon. Thank you, Adam!!

    Mark and Matt have visited my home for inspection twice now over the last few years. The…read moreprofessionalism and pride of ownership was clear from the moment they arrived, fashionably early I may add (being on time, an understandable challenge amongst LA contractors). We live in a 70 yr house on a hillside with amazing mountain views; but often besieged by the paranoia of being on a hill. Mark allayed fears both times, answered questions to explain the subtle phenomenon that concerned me every so often, & confirmed everything was normal. Inspections were thorough & no unnecessary work suggested. Often, homeowners aren't knowledgeable about civil and construction work. Speaking to these gentlemen is like speaking to professors who'll tell you clearly if you don't need work; and what you may need 15 years from now. We ended up being advised that nothing was needed to be done. The most remarkable example of integrity.

    Foundation Repair LA literally saved our house. Last year we found out that a wood-eating fungus…read morecalled Meruliporia 'poria' incrassata was growing into the side of our house. We first had a mold abatement company come and they revealed that the fungus had grown into the framing and had completely rotted out large areas on the side of our house. They told us that the job was too big and recommended Foundation Repair LA. When Matt from Foundation Repair LA came over to give us an estimate, my wife and I were immediately impressed by his thorough knowledge of this particular fungus and his ability to patiently explain the problem to us. The proposal he created was quite extensive and costly, but he explained that in order to prevent this fungus from coming back, they needed to completely remove it at the source and all of the contaminated soil. We got a couple of quotes that were less costly and chose another contractor to do the abatement, but we learned our lesson the hard way when after a month or so the fungus started growing back in the soil and the house framing. That's when we called Matt back and told him that we were hoping he would give it a chance. He immediately came over and looked at the work that had been done, giving us a less expensive quote to complete the job properly. Matt was very thorough and his team was professional. They kept in constant communication to update us on what they were finding and their progress. It's now been over six months since they completed the work and the fungus is gone. This was a scary experience and I am so grateful to Foundation Repair LA for saving our house!

Shay came by and immediately saw the issues. He helped me understand my options and provided the expertise I needed to get the foundation fixed, even offering to supervise the repair if it was done by another contractor. Nina prepared a quote that I submitted to the original builder. Shay offered advice throughout the negotiations and was always quick to respond to questions. The foundation was eventually repaired. It was a pleasure working with Shay and Nina throughout a stressful process. It was reassuring knowing I could turn to a trustworthy expert who had my back. I highly recommend Fidelity Green to anyone considering a foundation project. Thank you, Shay and Nina!

I had to wait another 2 days until they obtain for me an emergency repair permit (their structural engineer is professional and very productive as well!) They showed up 7am Monday morning with equipment and tools that I never seen in my entire life, they work is clean and organized and Pini the field manager was extremely helpful in answering and explaining few questions that I had. Repair (and building and safety inspection) was completed in 3.5 days, and today, they cleaned up and packed their giant trailer and left my property repaired and clean. Their cost was fair compared to another estimate that I received. It was truly a great experience. Thank you for a great job.

Some contractors only walked around the exterior of my home, while others took a quick look underneath. Jon, the field representative from Sunshine Foundation Repairs was different from the moment he arrived. He was on time, friendly, professional, and immediately went into the crawl space to perform a thorough inspection. I was impressed that I received a detailed proposal the very same day. The biggest reason I chose Sunshine Builders was the quality of Jon's inspection. He was the only contractor who identified sagging floor joists in my living room, which likely explained the squeaking floors I had been hearing. He documented the issue with photos and recommended the appropriate repairs, giving me confidence that he was looking out for the long-term integrity of my home--not just trying to sell a standard retrofit. Throughout the entire process, Jon kept me informed every step of the way, from permitting and plan check to scheduling the installation. Communication was excellent, and I always knew what to expect. On inspection day, everything went smoothly. The contractor arrived prepared with all the required paperwork, met with the City inspector, and ensured the inspection was completed without any issues. Jon made an outstanding first impression and represented Sunshine Foundation Repairs exceptionally well. His thorough inspection, attention to detail, clear communication, and guidance throughout the entire process are the reasons why I chose Sunshine Foundation Repairs I would highly recommend them. The proposal bid was right where my budget was.

The crew arrived early in the morning and got started right away. Everyone was in sync and worked efficiently, completing the job faster than I expected. They also left the crawl space clean and removed all debris and trash. I'm very happy with their service and would definitely recommend them.
