"Sinai Construction has literally saved our home and the homes of our two neighbors from sliding off a steep cliff. After interviewing 3 other companies we chose Sinai... Our structural engineer who is a UCLA professor was very complimentary upon the completion of work... on time and budget and without any corrections needed from him."

We're not just saying that. It's true! Check out our California State License Number (457238) and you'll see that it's the oldest in structural and foundation repair.
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 things moving much quicker.
We've been repairing foundations, retrofitting homes and solving drainage problems for decades. Foundations, structural work and drainage are ALL we do, and we are exceptionally good at it.
Every one of our employees undergoes a thorough background check. Your family is safe with Sinai. When our clients leave their homes, they come home to find nothing missing, nothing out of place and a mess-free job site, as promised.
Ask around. Our satisfied clients always compliment us on our extraordinary service. It's for this reason that we are a recipient of the 2013 Angie's List Super Service Award (we've earned the award for 3 consecutive years now; we also received the Super Service Award in 2012 and 2011) and the 2014 Talk of the Town Award (we also got this award in 2012 & 2011). This is also the reason why we have an A+ rating with the Better Business Bureau.
We really do have an exceptional crew. They start on schedule and remain on schedule; they don't jump from project to project but see every project through to completion. They arrive 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. Now that's the Sinai brand of service you won't get anywhere else.
The structures we lay down last, and they stand the test of time. We guarantee it. Our clients get a 25-year, transferable warranty on all structural work. This is a big plus if you decide to sell your house.
We have absolute confidence in the quality of our work. Our field personnel are foundation, retrofitting and drainage professionals. We have rigorous internal quality checks and every project undergoes periodic checks to ensure that plans are followed to the letter. We also thoroughly evaluate completed work to ensure that it is on a par with our high standards and that the foreman abided by our strict quality guidelines.
With Sinai Construction, there are no expensive surprises because our 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?
Even in situations involving hillside properties 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.
We are one of the most affordable foundation contractors in Southern California, and we can prove it. Going line-by-line and item-by-item, compare our proposal to others you may have and you'll realize just how much value you're getting with Sinai.
When we meet to discuss our proposal, ask us to prove our claim and we'll gladly show you how you'll save more money by choosing Sinai Construction.
At Sinai Construction, we'll tell things as they are even if it's something you may not want to hear. If our report says the problem is serious, it is. If our report says the problem exists, it does. If our report says you can't do some repairs without doing some other repairs first, you can't. We don't sugarcoat things; we won't lie just so we can seem less expensive. Likewise, if your structure requires only minor work, or even no work at all, we'll tell you. You can count on it.
Yes, we might lose your business by doing this, but our strict code of ethics won't let us simply stand by while you waste good money on work you don't need or repairs that won't work or last.
Our experience and expertise are indisputable. We have a General Engineering Contractors License and a General Contractors License. We have a soils and structural engineer on our team.
We have worked on public works projects. We get called to work on extremely complex builds. When other construction professionals need a foundation contractor with extensive experience and highly specialized skills in structural and concrete work, they call us. Repairing crumbling hillside foundations, shoring up failing slopes, replacing entire perimeter sections, hand-digging 30-foot shafts in inaccessible sites — that's all in a day's work for us.
