The difference between a foundation specialist and the real deal.

soft story retrofit _ concrete pour_edited_edited.jpg

Anybody can say they're a foundation specialist, but have they been repairing foundations, retrofitting homes and solving drainage problems for decades. WE HAVE. We're the real deal. Foundations, structural work and drainage are ALL we do, and we are exceptionally good at it. We don’t cut any corners. We don’t take any shortcuts. We do it once, and we do it right.

Award winning service.

Sinai CONSTRUCTION Awards_edited.jpg

Ask around. Our satisfied clients always compliment us on our extraordinary service. It's for this reason that we are a recipient of the 2015 Angie's List Super Service Award (we've earned the award for 5 consecutive years now; we also received the Super Service Award in 2014, 2013, 2012, and 2011) and the 2014 Talk of the Town Award (we also got this award in 2012 & 2011).

Our greatest assets are our crew.

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.

A firm price. Not a highly elastic price range.

There are no expensive surprises with Sinai Construction Engineering. 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.

Fast 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.

Security and peace of mind.
