    I want to express our gratitude for Zenith Engineers Inc. prompt, professional, and outstanding…read moreservice throughout our remodeling project. From the very beginning, we were impressed with Senthil, Ryan and other members of Zenith team's level of professionalism, prompt response, architectural knowledge and effective communication.This level of service was seamless through our entire engagement with Zenith Engineers Inc., from obtaining the building permit to successfully passing all necessary inspections by the SF Building Department. No one questions their architectural work because they are so good at what they do. We had some initial concerns after reading negative reviews, but as the project progressed, it became clear that those comments were based on personal grievances, rather than valid concerns. The team at Zenith Engineers Inc. has a high level of professional ethics and integrity. Zenith's management team had explained to us early on in the project, the strict adherence to code and compliance was paramount throughout the project. If Zenith compromises to satisfy unsatisfied clients, the building will end up being non-compliant and more importantly unsafe. We truly appreciate Zenith's commitment to quality and integrity, even if it means earning a few negative reviews along the way, which seem rather unfair to them as they are simply doing their job. I am extremely satisfied with the professional and excellent work the team at Zenith Engineers Inc. provided us and will hire them in a heartbeat for all our future structural and/or seismic engineering needs. Thank you Senthil, Ryan and the Zenith engineering team for your professionalism and support. It was our best decision to work with you and experience such high standard of professionalism, work ethic, and integrity.

    After having used Zenith for multiple projects in the last few years, looks like it's finally time…read moreto look for someone else for the next one. We started using Zenith because of its responsiveness and effectiveness when it came to structural design. With them as part of our team, we were able to keep up with the City submittal and response timelines we had set. Fast forward to today, and we can't get a hold of anyone. When we do, it's always an excuse for why they didn't respond, without a resolution. We sent them the last City comments 30 days ago and have yet to get anything viable to re-submit back to the city. Given that this is a 30-unit hotel project, going with a different firm now will mean a complete re-design of the project; an absolutely painful exercise that will set us back months. Zenith knows that. So it's absolutely shameful for them to act in a way that would even suggest that our only choice is to get the entire project re-designed by another firm just to have it keep moving forward. So much for "we respond to emails within 30 minutes and always answer phone calls" as outlined on one of their online profile. Knowing how we were treated on this round of City comments and the fact that the entire company seems complacent about what they try to embody in their rhetoric, I would stay away for any future project.

    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.

    I've worked with ProStruct Engineering on a couple of my projects for full plan sets, and I…read morecouldn't be happier with the experience. 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.

    We just did a mid size project with them last month. We had them underpin one side of the house and…read morereplace a good amount of posts and repair some cracks in our foundation. Brett came out to do an assessment on our entire foundation and his finding was consistent with our own inspection report. Their recommendation is also on par and we find that Brett is quite knowledgeable about the scope of work. He is also very patient, responsive and respectful throughout the estimating project while we took a long time to decide, a lot of follow ip questions and requests. Not once that I felt rushed, pushed or disrespected. The team kept me informed on the timeline of permit, project starting time, inspection and completion, everything was transparent. They passed inspection without problemsx Our foreman is Humberto who was polite, dependable and kept me well informed on the work they performed the day of, when they finished work and provided needed before and after pictures. I also find their pricing is reasonable compared to other companies that we interviewed with the experience that far exceeds their piers. Overall I had a good experience with the crew. They are polite and really didn't interfere with our life that much while they work. I would recommend them for all foundation repair needs. Be careful because lots of foundation companies will scam you, just because you will not be able to see what they did underneath your crawl space. The last foundation company came out to fix our house they made a bunch of noise for 2 weeks, said they are done and then we hired an independent inspector and confirmed they did nothing. Spend the money on a good company. This one is probably the best one ( we interviewed 6 companies)

    My large concrete driveway pad was settling and cracking, and I commissioned Foundation Solutions…read moreto level it, and repair some of the crumbling concrete. The experience was great. Kyle initially came out to evaluate my project and give me a bid. His communication was clear, and he assured me there would be a direct line of communication between himself and the crew who would be doing the work, which was one of my priorities in choosing a contractor. His bid was a little less than another bid I got, but cost was not why I went with them. Jason and Ernie then came out to do the work, and Jason had been briefed by Kyle with the nuances of the project. Jason was careful to describe what he thought would work best, and he kept me in the loop along the way. The work came out great, and no sooner had Jason and Ernie left than Kyle was on the phone to make sure I was satisfied with the work. Start to finish there was clear communication, effective follow-through, and my expectations were met. What more do you want when hiring a contractor? I would definitely hire Foundation Solutions again.

    Golden State Seismic & Structural - Trenching for rebar and concrete that hardy frames will connect to for softstory retrofit

    Brian, Holly, and Gerardo are the best…read more When I contacted them initially two years ago, within the first 10 minutes of talking they'd recognized that our house was not a simple brace & bolt project given its soft story and referred me to a structural engineer (who himself was excellent) for review/evaluation. I begin with this because that structural engineer mentioned he'd had Brian do his own retrofitting and highly recommended him, which was the only endorsement I needed. The scope of the work was soft story retrofit (incl. excavation at the front of the garage to install a Hardy frame, adding in shear walls with bolts, shear wall with URFP ties all along the house's perimeter) as well as adding in anchors (e.g., hand dug piers, rebar, concrete) in the front and back of the house to prevent the house from further sinking. We initially applied for and got into the ESS program, which Brian/Holly guided us through (pulling permits, getting photos, contacting our engineer for letters/responses on ESS program follow-ups). As in the first time and every subsequent time, they were swift and helpful in responding. ESS, if you don't know (like I didn't), goes through FEMA and requires FEMA review and approval of your plans at each step of the way, but the whole program came to a standstill in 2025-26. We had no updates despite us and Brian/Holly repeatedly following up. We gave up on ESS in April and decided to move ahead with the retrofit. Brian was able to work us into his schedule and work began early May and work was completed in just a little over two weeks, a full week faster than I expected. The whole time Brian/Holly kept us apprised of the status, schedule, and inspections; and forwarded us all documentation and pictures as they came up. The crew was efficient and detailed and did thorough clean ups of the worksite after each day. We felt in control and informed the whole time and are confident in the result; I'd hire them again in a heartbeat.

    I'm happy to add to the positive reviews of this company. Brian is very easy responsive, and was…read morehappy to answer all my questions. He went above and beyond to guide me through the process. Jordan and his installation team were very pleasant to work with. He even checked and discovered my newly renovated room may not be supported sufficiently. I hope I won't ever need it, but the work seems solid

    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.

    I hired Groundworks to repair the cracks around my in ground pool. The pool was installed in 1999…read moreand is still looking good, but the concrete structure showed its years and had linear cracks in places and one place the concrete shifted about a quarter of inch. So I thought I would have it repaired for beautification purposes. Brian the representative that came out is a fast talker and didn't explain the process of what Groundworks would and could do to improve the cracking of the concrete floor! I certainly thought that after paying $4000.00+ dollars I would be able to see a difference in the concrete. I didn't see no difference other than some lifting on the crack by the steps of the pool. Another problem I have is their is overspray of the polymer on my privacy fence. I know it is from the polymer because it is where they sprayed by the steps and diving board. I'm certainly not happy with the outcome.The crew that came were here approximately 1 hour 33 minute. WOW 4000.00 dollars just choose wisely ask a lot of questions make sure you understand what the process is. I will not refer them Stayprayedup DP
