This company is the absolute best! They took on a job at my house that over two dozen other…read morecontractors had looked at and could not figure out. My garage would flood when it rained heavily. The water was seeping/bubbling up through the concrete floor. Unfortunately,I spent a total of 20K on two other contractors before hiring Alpha. The work done by the first two contractors failed completely. When Damien from Alpha Structural initially came over, I knew I was in good hands right away. He is extremely knowledgeable, experienced, and professional. I would say the same about Brian and Nadir, who were the leads on my job. Brian especially, went above and beyond. Anytime I reached out to him he responded immediately, and was on site whenever I needed him. My garage was a nightmare scenario. I contacted just about every contractor who works on this kind of thing, from LA to San Diego. Not one of them could figure it out. Not one. This went on for 2 years. Alpha Structural took on a very tough job, and did what no other company could. They completely solved my garage flooding problem with a very strategic and comprehensive plan. Do yourself a favor and use this company! Don't waste time with others. Alpha Structural won't let you down.

15 years ago I had done a full remodel and built out the upstairs bathroom to include a jetted tub…read more Recently, after using the tub (LOTS of weight), the entire side of the room began popping and creaking. I knew enough about construction and engineering to seek professional input and reached out to Alpha Structural. They were pretty booked out, however when I explained the gravity of the problem (people in a home office below the tub area), Franchesca worked her magic and got me an appointment in 2 days. Damien showed up promptly at the 9 Am start time. We walked around the property while I explained my concern, and noted several other possible issues. Damien was extremely through, asking numerious questions and providing input and advice along the way. He took the time to explain causes for the different issues and was personable, professional and extremely helpful. Luckly for me, my problems traced back to normal settling, a recent solar panel and roofing job and normal aging. It's no wonder why Alpha has so many 5 star reviews- They absolutitly deserve every one of those. I only wish other businesses were as well run, and with such amazing people like Damien and Franchesca.

Jeremy and his crew are extremely knowledgeable and thorough in their analysis. Furthermore, he explained to me in great detail with various drawings what was happening to the house, with the final conclusion that there wasn't a significant issue at the moment. His explanations were detailed and easy to understand. I would highly recommend Jeremy if you have any questions about house settling or foundation issues, and would certainly call Jeremy again if I have any further structural concerns.

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.

We immediately engaged with him to create plans. He was so easy to work with. He always kept up with the agreed upon timelines and was great at providing updates throughout the project. We were so happy with his work and professionalism that we engaged him again to help with the daunting permitting process. He ensured that this process went so smoothly. He quickly and thoroughly reviewed comments from the city, saving us lots of time and frustration. Again, he provided updates throughout. Hamid and DSE have put us at ease that this terrifying problem will be fixed properly. This has been some of the best money that we have every spent.
