Re: Accessory dwelling unit…read more Houmam assisted me in designing and engineering an ADU (garage conversion). My situation was unique and very complex because of Zoning and building size. Houmam made sure what I wanted to do was possible by calling the City Of Long Beach prior to even charging me for a consult or a proposal. Although, initially, everything seemed straightforward, there were quite a few bumps in the road, and it was frustrating for all parties involved. It took about eight months for final approval because of the complexities but Houmam saw the project approval through to the end and made sure even after approval, that I had all of the info needed. He continues to be available to answer questions and follow up. He was patient and understanding with all of my questions and concerns. I look forward to updating this review with a picture of the completed project once it's done. I recommend HMS without hesitation.

After pointing out the areas of concern to him, Ken offered a couple non-serious possibilities for the phenomenon, and was able to assure me there was no threat to either the structural integrity of the house or the cement slab foundation - and pretty much bottom-lined it, saying there's really nothing to worry about. I really appreciated Ken's easy-going demeanor, and sensed zero interest in him trying to sell me a repair service that wasn't needed. Ken is just an honest guy offering his experienced opinion - in no doubt, putting yet another homeowners' unwarranted concerns to rest. Would be nice If all companies sent inspectors who operated the same way as Ken.

From start to finish, the level of professionalism, expertise, and attention to detail was truly outstanding. The engineer demonstrated a deep understanding of structural integrity while also respecting the design vision for the space. He carefully evaluated the existing structure and developed precise plans to safely support the load while allowing us to achieve the open, modern kitchen we wanted. His calculations and documentation were thorough and well-organized, which made the permitting and construction process much smoother. What impressed me most was his ability to balance technical precision with practical solutions. He communicated clearly, answered all questions patiently, and ensured the plans were easy for the contractor to follow. The result was a seamless transformation--our kitchen now feels bright, spacious, and beautifully integrated with the rest of the home. If you need an engineer for structural modifications, especially for projects involving load-bearing walls, I highly recommend his services. His expertise, reliability, and commitment to quality truly set him apart.

Jeremy was informative, responsive and customer service oriented. I first called him when I noticed…read morecracks in the stucco on the outside of my house and hairline cracks on the interior drywall. He came over and did some quick measurements and was able to tell us which direction and roughly how much our foundation was settling. He explained that in our area, clay-rich soils expand and contract with the wet/dry seasons and our issue was likely due to poor drainage in our backyard that allowed water to pool and seep under the foundation prompting one side of our house's foundation to settle (sink) incrementally over the years until the tension started to cause the cracking we observed. Based on the amount that our house had settled he said we were right in the gray area between just needing to improve our drainage and monitoring for further settling, or going the more expensive route and having helical supports installed under our foundation to prevent our foundation from settling further. Jeremy was not pushing us in either direction, just presenting us the information and allowing us to make our own decision. After doing a significant amount of research on foundation settling, we looked into getting some quotes and Jeremy provided multiple contractor references. We had four contractors come out and found that they each provide free quotes that included measuring with advanced equipment to determine precisely how much the foundation has settled (only around 1-2") throughout all sides of the house. Their mapping was more detailed, but fairly consistent with what Jeremy had originally told us which provided us some level of comfort that they weren't manipulating the numbers to sell us on needing more piers. There was one contractor whose measurements came in more significant than all the others, but it was not one of the contractors that Jeremy had referenced. Even though we weren't an extreme case, for peace of mind to stop the house from having any further settling, we ended up going with a contractor that Jeremy had referenced who had proposed a middle-ground approach using a limited amount of helical supports and expanding polyurethane foam to support our problem area. We were very happy with their work and it was a solid reference from Jeremy. Jeremy did also offer to help us draw up plans and assist with permitting if we opted to go that route, but due to the smaller size of the job, we chose not to pursue that option. There is a lot to navigate with evaluating foundation issues and deciding what route to take for each individual situation. It is helpful to have a knowledgeable resource like Jeremy who helped get us started and provide some helpful guidance along the way. Thanks Jeremy. *Note - photos are of third party contractor referenced by Jeremy to give Yelpers an idea of what final work ends up looking like.
