What Our Customers Are Saying

Russell M.

Kevin was an amazing inspector. Was quick to schedule and he was super informative. Would definitely recommend him to anyone who needs a foundation or structure inspection

Alex G.

I had the pleasure of working with Kevin during an inspection in Los Angeles. He was thorough and extremely knowledgeable. I would definitely recommend utilizing services. Thank you!

Sharon F.

I used SoCal Seismic for the Earthquake Brace + Bolt program, and I couldn't be happier. They handled all the grant paperwork and city permits, making the process stress-free and simple. Every person that I interacted with throughout the project was professional, responsive and very helpful. The crew that did the retrofit work was polite and super respectful of my home, taking the time to lay tarps and seal off the work area. There was nothing to clean up after they had finished! I'm so glad I chose them -- now I have peace of mind knowing my home is better prepared for the next big quake.

Michelle W.

YC builders are outstanding. We used them for foundation repair and the people at this company work HARD. They didn't rush anything, their customer service in person and over the phone was fantastic and at a competitive price for the quality they offer. The city inspector said they did a "really really great job"! I would certainly recommend this company. Don't cheap out with foundation work!

John R.

YC Builders did a very good job bolting my house to its foundation. They took care of all of the photos and paperwork that the EBB required me to have done to receive the $3,000.00 rebate. Their price was very reasonable and affordable. Thank you very much Lisa and Kevin for taking care of everything for me. May GOD bless you always.

Jean S.

We love working with YC! Very prompt, friendly, answered all our questions, and very knowledgable on foundation work and details! They take care of city permiting and even HPOZ (LA Historic District) permitting! If you're looking for foundation scope, big or small, definitely give them a call!

Jackie T.

Quick process to get an inspection in the home buying process. Completed foundation work in a timely manner. Responsive and professional. Highly recommend!

Vyvyan N.

YC Builders were extremely helpful in my home inspections. They were able to assist me in a short notice and were super reliable. The inspectors are very knowledgeable and will help make sure to inform you of any problems or issues regarding foundation. The rates offers were valuable and reasonable. Once you get your foundation inspected they send you a very detailed report on how to repair. I highly recommend this company if you ever need a foundation specialist.

Leo Barajas

John did a great thorough job on the inspection. On time and friendly.

Gene Chien

Kevin was fantastic. Very knowledgeable and an asset to the company. I did 2 inspections with him and would recommend his company for other home buyers looking to investigate a property prior to close.

maria limones

It was a great experience working with socal seismic. It was a quick process and detailed review at the end. Highly recommend!

Mike Naylor

I was referred to YC at SoCal Seismic by my general inspector about five years ago, and I’ve been grateful for that introduction ever since. YC and his team have worked on several of my clients’ homes — and even my aunt’s — and every experience has been solid. As a Realtor, I need partners I can trust, because I’m putting my reputation on the line with every referral. YC delivers every time. He communicates clearly, explains the issues without drama, operates with integrity, and gives honest, transparent pricing. I have extraordinary confidence referring SoCal Seismic to my clients, friends, and family. They’re truly in good hands with YC and his team.

Russell Ma

Great inspector, quick to schedule and very informative

carmen shiau

Kevin is efficient and details. Highly recommend.

Zachary Hall

Kevin was an awesome inspector, super knowledgeable and friendly. He walked me through the entire process and really made sure I understood everything through the inspection process. I would highly recommend him as your next foundation inspector!
