SUCCESS STORIES

What Our Clients Are Saying

See why homeowners and industry professionals across Southern California trust us with their projects.

"I had an excellent experience working with Bryan, Josh, and the ProStruct Engineering team. They are responsive, knowledgeable, and committed to delivering high quality work. They expedited our project before a holiday deadline and provided a complete and well coordinated structural package. Throughout the process, Bryan communicated clearly and made sure every question and comment was addressed quickly. I truly appreciate their professionalism and reliability, and I highly recommend them for any residential structural work."

"ProStruct Engineering did more than I could have ever expected of a structural engineering firm. They responded to my somewhat panicked request to turn around a structural evaluation and submit a written summary report within 7 calendar days -- which because of the holiday really only left them 4 business days. THEY DID THE EVALUATION AND WRITTEN REPORT IN ONLY 3 CALENDER DAYS, ONE OF WHICH WAS 4TH OF JULY! I was blown away not only by this Herculean result but also by the availability of 4 or 5 senior project engineers and senior management to return my emails, phone calls and texts over the weekend. They were always available, always helpful, always had a "whatever it takes" attitude. In summary, the speed to schedule the process and sign the contract, the thoroughness of the evaluation and the speed in returning a written report, we're nothing short of amazing. And even their pricing was better than that of other companies contacted. How many ways can I say it? Ten Stars!"

"The whole team at ProStruct has been wonderful to work with! I'm an Interior Designer in the Central Valley working on a project at the coast and was happy to find someone willing to go the distance (literally) to get my project done. Communication was exceptional from day 1- each team member from Lead Engineer, to Project Managers, to Billing were quick to reply. I was able to wrap up my entire project in the time it took several other companies to initially reply to me. I'm already in the works with another project with them and will gladly recommend their services again and again."

"Irvin and the team were very easy to work with. Excellent customer service while going above and beyond. Answered all my questions and guided me through the process from start to finish. Also, the best prices out there for any projects!"

"TBH dealing with engineers often can be a headache and not always the best part of getting a project started. Many engineers see things one way and are immovable even though every project is different. I describe Pro Struct as 'Modern engineering' in the sense that with strong engineering principles, open client communication and a collaborative team can produce multiple perspectives and solutions for any project. Had a fire that damaged open web floor trusses in a high value home that scared off a handful of engineers until Pro Struct. The turnaround time was unreal. Bryan was never rude or too busy to address my concerns and listened to my ideas and I felt really involved in the process. Thanks Pro Struct and hope to continue to work with your team!"

"ProStruct performed an assessment of a structure that a neighbor built on our property to ensure proper removal. They were responsive and came out right away. They provided an evaluation report which was very helpful to ensure the removal was done properly. The report was very helpful for us and the company removing the structure to understand what needed to be done so that other damage did not occur. The engineer that was knowledgeable and pleasant to deal with as the other people in the office. I would use them again. and recommend them."

"PROSTRUCT is an easy company to work with. They are flexible and listen to their client's request and needs. The turn around time is very reasonable and I felt that I was kept in the loop at all times. The team seems to work as one unit, helping each other figure complicated builds. The price is budget friendly."

"Working with ProStruct Engineering has been such a positive experience. I've been working directly with Lokesh on a current project, and he has been very easy to reach when I have questions, and quick to respond. Having a company, and individual within that company, act as an advocate for the success of your project, in the most timely fashion possible, is both powerful, and uncommon! I recommend ProStruct for your structural engineering needs. My sincere thanks to you, Lokesh, and ProStruct!"

"We used ProStruct as our structural engineering contractor during the extensive remodeling of our home. Walls were removed, a new loft was added and our original main staircase railing was replaced. It was a lot, and they stood by us every step of the way. They were quick and responsive and everything we could have hoped for. I think we're done for now, but we would choose these people for our next project without hesitation."

"I am very pleased with the service provided by Irvin and Gary at Prostruct. Irvin responded to my call right away, answered my questions during the consultation and agreed to send a structural engineer to inspect the house I was planning to purchase with a days notice! Gary and team (engineers who performed the inspection) were thorough, taking the time to explain their findings in a clear and understandable manner. They answered all of my questions and provided me valuable insights about the work performed on the house (seller had added a new wall and taken out a section of another wall that was partly load bearing). Based on the insights they provided, I decided to not move ahead with the purchase and was glad I had hired them. Even after the inspection, Gary, Irwin and team were extremely helpful and provided excellent customer service. I highly recommend this team based on the quality and professionalism of the services I received."

"I had a great experience with ProStruct Engineering recently. I needed a structural inspection done on a property for a buyer who's closing date was less than a week away and ProStruct Engineering stepped up. After reaching out to them, they set me and the buyer up on a call with a project manager, Irvin Chua, who worked with us to understand the scope of the investigation and was able to schedule an engineer to come out next day to look at the property. The engineer, Chams, came out promptly the next day and was able to investigate the deck in question and took the time to walk his through his findings. He wasn't able to enter the crawlspace, but he later reviewed pictures and videos we sent and incorporated them into his report. He was able to speak to the stability of the deck, his assessment of the foundation, and any improvements he would suggest (redirecting the gutter water). We were on a tight timeline and both Irvin and Chams accommodated us, answering all of our questions before the report was ready and making sure we hit our timelines. Really appreciate their hard work!"

"I received great service and attention to detail. Our city was ridiculous to deal with. They sub-contact out the approvals to third party. ProStruct was patient, kind, and fast with all the changes that were needed. It was amazing how fast these got done. I also appreciated the communication and updates. I could not be happier and will definitely use them for my next project."
