The difference between a foundation specialist and the real deal

Anybody can say they're a foundation specialist, but can they say they're one of the home foundation repair companies that have been repairing / replacing foundations, seismic retrofitting homes and solving yard drainage problems for decades. We're the foundation repair contractors that have. We're the real deal. With years of solving everything from foundation replacement problems to yard drainage issues to soft story retrofit questions, and we are exceptionally good at it. We don’t cut any corners. We don’t take any shortcuts. We do our structural concrete work once, and we do it right. That's why all our structural concrete work comes with a 25 year warranty.

Award winning service

Handpicked construction crews

We really do have an exceptional crew. And it didn't get this way by accident. Each crew member has proven themselves to be a Sinai Construction team player and dedicated to each and every construction project. How many home foundation companies have the reputation we have of starting on schedule and remaining on schedule. We don't jump from project to project but see every project through to completion. Our crew arrives on time, they're very polite and they work quietly — no cat-calls, wolf-whistles and loud music. They help with the traffic when they need to work on the street. Best of all — they do DAILY CLEAN UPS. That's the Sinai foundation repair company service you won't get anywhere else.

A firm price on all construction projects,
not a highly elastic price range

There are no price surprises with Sinai Construction Engineering Estimates. Because our seasoned  foundation repair contractors proposals contain precise pricing information. Isn't that preferable to getting a very low estimate initially then halting the project midway because costs that should have been anticipated are piling up so quickly? That will not happen with Sinai Construction Engineering.

Even in situations involving hillside property foundation estimates, where unknown variables could lead to changes in the scope of work, we still strive to give you a sense of just how much you may actually have to spend. We anticipate possible scenarios and approximate potential major expenses, so you are never caught unprepared on any construction project. If you have hillside foundation issues, you want to avoid surprises. They can be pricey.

Turnaround inspection report in 24 hours

We make things happen. That means for houses in escrow, we submit our inspection findings and proposal within 24 hours. If you're buying, that means you can decide faster. If you're selling, that means you can get the process of selling your house moving much quicker. Just one more reason our clients consider us one of the best foundation repair companies in LA.

Every earthquake retrofit project is a team effort a clients earthquake retrofit review

Daniel, Carlos and the entire Sinai construction team did great work and were very easy to work with.  Also everything was cleaned up nicely every day the crew finished work and they started work first thing in the morning every day.  I did a complete earthquake retrofit and there was a lot of behind the scenes work that needed to be done with the city, permits, photos, etc. before they could even start the work and Daniel was on top of everything from the get go.  Also, Daniel was extremely responsive in returning calls, emails and overall keeping me in the loop of entire process.  Very happy with the outcome and would highly recommend anyone looking at a construction project to give Sinai a call-great job!
