Dealing with foundation issues had been super stressful, especially since the vast majority of…read morecontractors and engineers have been slow to respond. PJC, on the other hand, came out promptly to test our soil to determine why our house was shifting. They were professional, thorough and provided a lengthy report in a short time. We consulted with them several times after at no additional cost and got a review letter to pull permits super quickly even though they were swamped. They are nice, knowledgeable people. Highly recommend!

UNETHICAL BUSINESS PRACTICE. BEWARE…read more I called PJC & Associates and spoke with Kelli to inquire about a pull test needed to satisfy the city for our building permit. After connecting me with her associate Jacob Allen, confirming they can get this done, Kelli said she would send a contract indicating the pricing for these services. After receiving the contract with the attached list of fees and general services, I called and spoke with Kelli to specify which fees and services would apply to us. What we requested was a minor task that would take only about 30 minutes to complete. I mentioned specifically that before I signed the contract, I needed to know what fees applied to this pull test so I have an understanding of what I would be paying. She said the total would be around $460. I then asked her if that included a report to give to the city confirming the pull test was completed. She told me yes, this would include a report that I could give to the city. I waited two days after she sent the contract to sign it, ensuring we agreed on the cost and that I was comfortable with the expense before hiring PJC & Associates. Two days after we spoke and agreed on the cost, I signed the contract. Jacob Allen came out to our property, performed the pull test on the playground anchorage, held it for 30 seconds at a 500 lb. as instructed, and it was done. He was on our property for no more than 30 minutes to conduct the pull test.  A few days later, Kelli emailed me an invoice for $1120 and said that she would send the report I needed once the invoice was paid.  After receiving this email, I called Kelli to clarify why she had sent an invoice for almost triple the amount we discussed in our initial conversation regarding the scope of work and its cost. Kelli said the significant cost change was due to my report request, to which I responded by reminding her that the report was part of the conversation since the very beginning. I reminded her that the entire reason I called to begin with to inquire about this pull test was because I needed a report to satisfy the city for our building permit. All she could say to me was, "You signed the contract."  A few days passed. I then decided to stop by the office, hoping to resolve this with the owner Patrick Conway. I met one of his associates at reception who was very kind in walking me straight to Patrick's office and introduced me. As I sat with Patrick and began to lay out the situation and how this was clearly unethical business practice, Kellie came into the office during our conversation and once again could only say, "You signed the contract." I reiterated everything to her in person as a reminder of what was discussed and she walked back to her office. After she left, Patrick and I reached an understanding. Patrick let me know that I would pay the initially discussed $460, and they would not be sending me the report." I told him that was fine. We shook hands, and I left. Kellie, then sent me an email letting me know that Patrick told her they will not be revising the invoice to reflect our initial agreement. Beginning a business relationship with a conversation that clearly outlines the scope of work and the associated cost, only to completely change the agreed-upon terms by sending an invoice for almost triple the amount, is not only unethical business practice but also corporate misconduct.  I have been doing business with many individuals and companies over the years but this one is definitely one you want to stay far away from. If I would have known the amount of $1,120 they wanted to bill me for the scope of a 30min pull test and a report, I would have said no thank you, hung up, and called one of the many other options that have integrity and understand ethical business practice. Allow me to save you some major headaches... HIRE SOMEONE ELSE!

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.

Their team is very professional, responsive, and easy to work with. The plans were well-prepared and detailed, and the city approved them with minimal corrections, which really speaks about their quality and attention to detail. One of the projects was on a hillside property, where the foundation requirements were quite intense, but their team handled it seamlessly with well-thought-out and detailed designs. See pics. They always delivered on time and maintained excellent communication throughout the process, keeping me informed at every step. I highly recommend ProStruct Engineering to anyone looking for reliable and efficient structural design services! A special mention to Lokesh, who I worked with directly -- he was very responsive, understood my needs clearly, and made sure everything was addressed on time.

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

Part one of a two part foundation project Recently we had…read moreour house foundation repaired by Groundworks out of Fairfield. One bedroom had sunk by almost 5 inches as that part of the house had been built on fill. In order to restore the house to it's proper level numerous foundation jacks and floor leveling screw jacks were required. In addition some landscaping bushes and pvc sprinkler pipes had to temporarily removed. Groundworks had informed me prior to starting work what would be required to successfully complete this project and had my full approval. The house is now level, the doors no longer swing on their own and the interior cracks between the walls and ceiling joints no longer exist. Prior to the crew leaving the yard was cleaned up and the pvc pipes replaced. Best of all Groundworks will come back annually to the next 5 years and make any necessary adjustments. The Groundworks crew that made this happen was Andrew, the site supervisor, Charlie and Allen. Their performance and daily communication was superior on all levels. This is part 2. The Groundworks Poly crew of Anthony & Brian were very fast and efficient in completing their part of the foundation repair contract which was to level our family room slab floor. Fast, yes, but Anthony did take the time to not only explain what they were going to do but also walked me through the process as they were working. I have no problem in recommending them & Groundworks to other home owners who need to have their foundation repaired.
