    One corner of the crawl space retrofit.

    This could be a daunting process especially since it is not something most home owners know anything about, but Jony was good at keeping me up to date on each step of the process. It takes longer than one would think with permits and approvals, but he was on top of it and got back to me when things were ready to proceed to the next step. The work was done quickly and seemingly with efficiency. I would certainly recommend him for any retrofit projects.

    Earthquake retrofit and EBB process went great with JM Building. Jony made the process seamless answering all my questions and concerns. The crew were awesome during construction arriving on-time, putting in a full day and cleaning up afterwards. I highly recommend this team if you are in the market for foundation work. If you are looking to go through the EBB program, this company is a good fit. Prices are fair and they are great to deal with.

    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.

    Let me begin by saying I dreaded having my long, narrow, crumbling driveway redone. However, it…read morebecame a hazard. My first contact was with Matt and from the first meeting, he was informative, professional, on time, and personable. If I had any questions, he was quick to respond. The demo team and construction team were friendly, experienced, and knowledgeable. The men were easy to have around. Miguel oversaw the whole driveway project and he was also easy to approach and answered all of my questions thoughtfully. Cesar, who came to work on the driveway everyday, was also a gem. If I could give you more stars, I would. Thank you for a project done to perfection. Foundation Repair LA also did our seismic retrofit. Cesar, Magdaleno, and Cesar were outstanding. They had the project completed on schedule and were also easy to have around. Matt also set up this project for us and it was very easy to complete. It took two days. The cost of both projects was within reason and they gave me a discount because of having both projects done one right after the other. The whole team made for a positive experience. Taylor in the business office was also responsive and friendly. Thanks to everyone at Foundation Repair LA. for making a dreaded project easy to get through. My new driveway looks great, by the way.

    Sunshine Foundation did our inspection during escrow, and after we purchased the house, I had a few…read moreother companies come out for second opinions. Truthfully, no one came close to the knowledge, honesty, and thoroughness of Solomon and the Sunshine team. What stood out most was that they never tried to oversell me. They were straightforward about what needed to be done and what didn't. The dirt removal ended up taking about twice as long as originally estimated (not their fault - there was was just way more dirt than was viable), but they still did not hit me with a change order. Finding a contractor that is honest, communicative, and actually sticks to their word feels almost impossible, but Sunshine did exactly that. I also asked them to move the start date up by two weeks because of our move-in timeline, which was a huge ask. Ram, the owner, personally made sure it happened and clearly moved things around to make it work. Ram and Solomon were available throughout the entire process, from start to finish, and they even had their crew working overtime to help us hit our target completion date. They truly went above and beyond. Sunshine did an amazing job removing a massive amount of dirt and reinforcing our raised foundation. I will be doing seismic retrofitting with them in the near future. I could not recommend this team more.

    I never imagined our seismic retrofit project could go so well or I wouldn't have procrastinated so…read morelong to get it done. My husband and I knew we should get earthquake insurance but the cost blew our minds but when we heard that you can get a 25% discount if you complete the retrofit, we explored what it would entail. Well the EBB subsidy which came out to $3,000 was a huge motivator. Selection: To select a company to work with I went overboard reading reviews, not just looking at ratings- Yelp, Google, Angi, Houzz. Plus, I always look at Next Door because our city is finicky so I wanted to see which companies had delivered excellent experiences for homeowners in our city and lastly I look at Reddit. I invited 3 highly rated companies with excellent track records to provide quotes based on the work required. Out if the 3, two came, went into our crawl space and provided a detailed breakdown of the necessary work and cost with photos. The third company provided a quote over Yelp without coming in person to do a visual inspection. So they were eliminated from consideration. The remaining two which included Sunshine were excellent and after putting together a side by side comparison of the work and costs along with their answers to some initial and follow up questions from my husband ( who was a 35 yr construction industry executive), we selected Sunshine and specifically Adam who was the lead that came to our house and who provided detailed and technical responses that instilled so much confidence. EBB approval: Well from there, it was like we had a retrofit concierge with Diana guiding me through every step which is necessary because there are things that need to be done on the EBB website to ensure compliance to receive approval and given Sunshine's vast experience, they have it down to a science which eliminates a ton of confusion I am sure I would have had to face without them. The retrofit work: The team was on time, had detailed instructions, and worked diligently the entire time they were here and they provided photos of their work. And a bonus was I didn't have any clean up to do afterwards. I need to note that out of an abundance of caution Adam ( who is also a licensed electrician) came back out to take care of a wire that looked suspicious but was probably not an issue. If he had not mentioned it, we would not have known City inspection and approval: A breeze! The gentleman that dealt with the city came by after to give us the good news and it was apparent he was trusted by the city inspector. Retrofit completion certificate Diana expeditiously provided the certificate i needed to provide my insurance broker to get quotes after instructing me on how to complete the final EBB steps Success! We now have earthquake insurance and saved 25% off the premium. Side note: get your quote from GeoVera and not the Earthquake Authority. our quote for better coverage by a more highly rated company saved $1,500 in annual premiums So, for a project that seemingly would have been a bear, it was probably the easiest construction like project and process I could have imagined that gives us added confidence in protecting our home. Do it and include Sunshine in your short list. you will be happy you did.
