I contacted the engineering group at MKM and was put in contact with Nick Stuart. Nick came out and did a site visit and then worked with a designer to work on a voluntary repair plan to better support my foundation and wall. The experience while working with him was great. He was very responsive, kept to a schedule and came in at the budgeted amount forecasted for the work. He even did above and beyond items, dropping copy of plans off to me while I was at the permit office! I would absolutely recommend them in the future and plan to work with them again on a second unit in the upcoming months. They are extremely professional, have a great work ethic and do a great job!

Working with Irvin at Prostruct Engineering was a breath of fresh air. After purchasing a new home…read moreand enduring my first winter, I was incredibly nervous to find significant water in my crawl space and cracks along the raised foundation. I initially signed a contract with Prostruct, but after Irvin reviewed my photos, he demonstrated a level of integrity that is rare to find. Instead of taking the job, he honestly informed me that my specific issues fell outside their scope. He took the time to explain what I was seeing, referred me to a geotechnical engineer who could actually solve the problem, and issued me a full refund. I greatly appreciated his transparency and professional guidance. I highly recommend Prostruct Engineering to anyone looking for an honest assessment--they clearly prioritize the customer's needs over their own bottom line.

DO NOT USE THIS COMPANY -- terrible communication and shady tactics…read more I reached out to ProStruct Engineering for a simple onsite structural evaluation at my home in Danville. They sent a 10-page contract and demanded the full $1,100 upfront the same day, before any work was even scheduled. After I signed and inquired, I asked the project manager multiple times for a firm date when the engineer could come out for the survey. Instead of giving a straightforward answer, they used clear delay tactics and kept putting me off with vague responses. When I finally decided to cancel before any site visit or report was started, their own contract (Section 5.5) clearly states I should only owe a $500 "setup fee." Yet they are now treating it as if I owe the entire $1,100. This is a classic "pay us everything first, then we'll drag our feet" operation with a heavily one-sided contract designed to trap customers. Save yourself the stress, the risk of a lien on your house, and the endless runaround. There are plenty of other licensed structural engineers in the Bay Area who actually communicate and don't play games with scheduling. Would not recommend. Proceed with extreme caution.

I hired SF Bay Engineering for seismic retrofit plans under the Earthquake Brace and Bolt program…read more I was told architectural drawings were required before they could proceed, so I hired and paid an architect to prepare them. After multiple back and forth and with SF Bay Engineering admitting they aren't familiar with the requirements, they terminated the contract. They refunded their engineering fee, but the architectural cost remained my responsibility. I brought the matter to small claims court, and the court ruled that because I retained the plans, reimbursement was not warranted. I recommend future clients clarify in writing how architectural costs will be handled if SF Bay Engineering terminates the contract. Happy to provide additional details upon request
