Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!

I contracted Alpha Structural to do a partial foundation replacement of my hillside property in LA. They were very responsive at the beginning in making me feel that they were the right company for the job. Their work reputation seemed good and I felt comfortable with the lead contact, Aaron, when he explained the care and detail the company applied to their work. They pointed out that plumbing had to be moved and recommended a company, Hector Gomez Construction, with whom they would coordinate to do that work. During the first part of the job, they would notify me only the day before or sometimes the morning of that they would shut off the water and/or electricity to the property in order to do their work. This proved a severe inconvenience that could have been handled much more responsibly with better planning and communication on their part. When the excavation phase began, they ripped the sewer line, causing damage and cleanup fees to be added to the budget. LA Housing then shut down the project for a few weeks because no permits had been pulled for the plumbing work, causing me to have to be in touch with the city weekly in order to coordinate inspectors' visits and paperwork. Halfway through the work, the doors in the house became inoperable. Interior doors would not close and exterior doors were hard to budge or stuck shut altogether. I notified them of this safety issue, to which they said they would respond to, but took weeks of reminding before they did anything about it. Towards the end of the work, their foundation adjustments caused over $10k damage to the interior of the building including a tile floor replacement, cracking grout in the shower, and large gaps between the windows and the walls. I told them my concerns and they said they would "work with me" to find a solution. They sent a contractor to fix these issues. When I asked repeatedly about how we could agree on payment, they told me they were not responsible for damage to the property. This was an element in the contract that when I asked about at the beginning was downplayed. If I had any idea they would cause such extensive structural damage and not pay for it, I would never have hired them. They will fix your foundation, but at great cost and inconvenience.

Excellent experience again with Alpha Structural. Charlie Rosenkranz came to see the 3-story apartment building in West Hollywood. We discussed what the soft story retrofit plans will likely include. He's knowledgeable and experienced. We appreciated his professional no-pressure approach and answering our questions. Alpha performed an exploratory investigation of the support structure, as architectural plans were not available. They engineered the plans with city approval. They then consulted with us and provided the approved THP (Tenant Habitability Plan) paperwork. Production Manager Dave Schlaich and Job Supervisor Seth Price met me before construction. Dave went over the approved plans and explained the work that would be performed, and the purpose. They both answered all my questions. Lawrence and Antonio were the main work team. They were very pleasant and answered all our questions. Both had great explanations with Lawrence being very detailed. Seth provided timely progress reports by phone and text. He answered all questions, and provided contacts for automatic shut-off gas valves and stucco work. Despite Covid-19, they scheduled and passed inspections, and completed the work in under a month. We've seen projects by other companies stuck in limbo for months with no progress, so we chose Alpha to avoid complications. They removed all debris, and left the property clean. The tenants and neighbors had no complaints. Daniel Aparicio also explained various issues. Communication with everyone, including the office staff, was excellent. We're very pleased with this experience.

This is THE company to use. I had an old 1907 wooden house sitting on a decaying brick foundation and needing a sister foundation installed and a complete seismic retrofit. Even during the bidding process, Brad from Alpha was extremely attentive without being assertive. I contacted four other companies although one I eliminated since they charged a fee for inspecting. Alpha was very timely with their bid and flexible when I needed help with the budget. All the way through the process, every single person at Alpha was extraordinarily good at customer relations, returned emails immediately, and stayed in constant contact throughout the entire process. Whenever there was a slight change to the original plan due to permitting or a plumbing adjustment, Alpha was very proactive and made sure everything was communicated clearly and promptly. I have really NEVER worked with a company that had such excellent communication skills. This is really one reason I selected them to do the work and, even though they may not have been the least expensive, it is worth the extra price for this reason alone. And Alpha Structural's work speaks for itself as well. Everything was done precisely and well beyond code, an unbid section of foundation was provided under the front porch without increase to the budget, and all materials used were of the highest quality. The project went on somewhat longer than estimated due to permit changes and a short weather delay but was still finished in a timely way. My home is our family's largest asset and it is a great relief to now know it is sitting on a solid foundation. The entire process from first to last was excellent and I cannot say enough good things about the way Alpha Structural handled the project. From the front office to the boots on the ground: A++

They were the best of the best. We interviewed other companies and they have everything in house to make a large project like this be very smooth. From pulling permits to engineers to explain the job they do everything in house which no other company could offer. From start to finish so professional and answered every question or concern along the project. Incredible crew and upon finishing the project they left it cleaned up and you wouldn't know they were there. I cant' say enough positive things about this company they are amazing.

We had excellent experience with Alpha Structural. Charlie Rosenkranz came to see the property and advice. He checked the structures all around and looked in the basement as far as possible beyond the ducts that were filling up the space and would require tunneling to get to some areas under the building. Communication was excellent. He's knowledgeable and experienced. We appreciated his professional no pressure approach and answering our questions. The front main duplex needed Seismic Retrofit; it wasn't bolted and had cripple walls. There were suspect areas in the foundations that would have to be tested when bolting, to see if the concrete is in good shape. After we agreed to their proposal have the work done we scheduled a range date. They had to submit to the city plans for a permit to do the work and wait for the permit to be issued. While doing the retrofit we found out that the foundation in the front corner was damaged and that the building has sunken and was not level at that corner. Charlie worked out the details and bid for the additional work of Partial Foundation Replacement, Posts/piers, and Jack Lift the corner to level it. He explained the details and what's involved to my satisfaction. Alpha obtained the permit for the work and proceeded. The work crew did excellent work. Jose Morales was the Project Supervisor. They completed the work at a good pace, including the delay for the additional work permit, without complications or complaints from the neighbors. The place was left clean. The work was approved in the inspection which they requested and scheduled with the city. The communication with everyone at the office was also very good. We're very pleased with the experience.

Alpha was professional and efficient in getting our earthquake retrofit done and they knew how to work with the earthquake brace+bolt program smoothly. We were very pleased with their work and would recommend them.

This is our second time using this company, both times the appraiser was fantastic, but in this instance Lisa, their Director of Customer Service seriously bent over backward to help us out with the home one of our clients is purchasing. She was amazing and pulled off the impossible, getting an appraiser out to inspect the home the following day and making certain that everything was covered. Amazing customer service, very thorough and helpful technical staff, quick turnaround on the report and just plain a great company all around. We could not have been more pleased with all that they did for us and our client.

The mark of a good company is not how they handle things when everything goes right, but how they handle things when things go wrong. I live in a 100 year old house, and old houses have surprises. On two occasions, my house gave Alpha a little more than they were expecting, and both times, they stepped up and proved why they have the reputation they do. The first time, the footing under my kitchen was undermined, and they intended to put two concrete pads in to fix it. When they realized their initial plans to fix it weren't quite sufficient, they brought out one of their in house engineers, and they built Fort Knox (in a good way) under the kitchen. The kitchen of my house is probably the most secure part of my house now. It will survive the Apocalypse. Then, they were contracted to fix the the stairs in the back of my property. The side of the stairs was separating from the stairs themselves, and Alpha was contracted to replace the wall. But when they removed it, they found the the old stairs there were just a thin layer of concrete over loose rock, which spilled out undermining them. It's something they never could have seen or known from the outside. Mark, one of the bosses of the company came out and looked at it, and had them replace the entire stairs, which now look amazing and are very safe for my children. I also can't say enough how on top of it the people were. Dieter, their supervisor, was amazing. He stopped by frequently to make sure everything was on track and up to standards. You'd hear him pulling up on his motorcycle, and if you had questions, he'd talk through everything that was going on with you. (And be very patient with you about the questions.) When there were job hiccups, he just let me know that they had it under control and was unflappable. He always told me things were going to be fine, and then took care of it. His crews were professional, considerate, hard working, and polite. If you get any of the guys I had, you're in good hands: -Oscar and Marlon did an amazing job on the kitchen underpinning, bolting, and sheerwalling my basement. -Gregorio, Jonathan, and Henry were excellent, and replaced my stairs. (And Gregorio, in particular, is an artist with cement.) Both crews made me realize how consistently good the quality of the work done by this company is. I highly recommend Alpha, especially if you work with any of these crews.

I couldn't be happier. The inspectors, Brad and Matt, were very professional. They did a drawing of the perimeter of my home. They spent a good deal of time under my house. They told me that my house is actually bolted. Some of the bolting is up to code and some is old, but bolted. I was so relieved since I got a quote from another contractor for thousands of dollars to bolt. I am so grateful to find an honest company. Thank you Alpha Structural, Inc..

Alpha Structural are class acts 100%. Dick came to my house, gave us an honest estimate under what we had expected and got us on the books promptly to begin work. The foreman, Jose, was attentive and polite throughout the work. The stars of the show, Lawrence and Antonio, blew us away with their work. They gave me regular updates and got the job done, start to finish, with utmost professionalism. Little things, like pulling in my garbage cans after collection, just really made their work ethic and politeness stand out. With their stellar reputation and amazing performance, I trust this company with any foundation work I'll hopefully not need in the future! I just wish they provided more services so that I can work with them more.

It went well. The guy was quite experienced. The coupon I bought cost $225. I haven't got a chance to talk with them yet. Just based on the inspection alone, I give them an A. I got a coupon and a pretty good deal for the price of the general inspection. I haven't got a report so I don't have a lot to say in that case. I think the inspector is experienced, quite truthful, very objective, and his explanation is based on the facts so I appreciate that. I would definitely consider them in the future.

From the first phone call I knew that choosing Alpha Structural was the right choice. Sandy went out of her way to schedule an inspection for a hillside home purchase. She was able to work her magic a squeeze us in due to our limited time frame. The inspector, Erinn, was prompt, professional, friendly, educated and thorough. He analyzed every inch of the property and delivered a written report the following day. This company was a joy to work with and will be used on all of my future purchases.

They were super professional. The inspection, work appointments and clean up all were on schedule. The only delay in finishing was due to the City inspector being a day late because of July 4 holiday, not Alpha's fault. The final inspector was really impressed with the work. They cleaned up very well, and even put concrete into the stucco gap after jacking the wall up, which was not on the original work bid. The two workers, Juan and Vicente, did a pretty amazing job, given how hot it was those days and the very tight quarters they had to work in.

Excellent! The structural engineer came out immediately for the assessment. The start date was set and everything went smoothly. Every Alpha employee is professional and friendly, prompt, knowledgeable, and responsive to emails. They show up on time, get the job done, clean up, explain everything in detail, and prices are more than reasonable! I can't begin to express how happy I am dealing with Alpha. They are refreshingly honest and don't overbid. We also had another buckling wall at another property that they handled as well. One cost $4300.00 and the other cost $5900. We are using them for our earthquake retrofitting as well at 2 other properties. Will report back when those jobs are complete.

Great customer service (ask for Lisa Hunter -- she'll make sure you get an appointment and that they understand exactly what you need done). They were able to squeeze me in next day for a CEA earthquake retrofit inspection. I was a bit nervous that it would lead to them just "finding" work needed on my house, but, instead the inspector came and told me I was good to go, that if I needed work in the future to consider them, and he signed off on my bolt/retrofit. Price was $250 for inspection; not cheap, but also not terrible, and I wanted a qualified firm so very fair to me. So nice to find an honest contracting firm, and with good service (even showed up on time). Highly recommended; I'll have them bid if I need work done in the future.

They made one mistake, they reinforced the wrong place. I was like this is wrong. You suppose to do my bathroom. It was expensive. It cost a lot more this time. They made a mistake too. Overall, they are a good company, and I would use them for the next time. The fact instead they finished in one day, the finished in three days. I have to take off from work. I was uncomfortable. Their people wasn't doing it right, and I had to supervise.

Very exact. They gave me an guarantee that my problems won't returned. That is what happened. My roof was cracked out. That humongous tree fell on my house twice. My one corner of house was devastated from it. They were able to pull it up. They were able to fix it up. Not fix up the cracks. They cracked it up when they fixed it. Everything is back, and normal. It never sank again. They advised me how to re-slope the grounds around my property. Regraded. I followed their advice, and I don't have problems anymore. I had water problems around the foundation. The grading was wrong. I fixed it all, and everything went away. Just as they told me.

We recently bought a 100+ year old Craftsman with original river rock/mortar foundation and decided to bring it up to seismic standards. We called 3 highly reputable, highly rated companies on Angie's List, all of whom recommended the same scope of work, and went with Alpha based upon their highly competitive price and recommendation by another contractor. Brad came out to do the inspection and was always available to answer questions prior to the start of the project. Was told it would be a 2 week project start to finish, 88 linear feet sister foundation with post/pier improvements. Alpha truly delivered in every aspect. We had the same crew for the duration of the project. 3 men, Abel, Margarito, and Roberto, and Steve was the project supervisor. The 3 man crew was awesome working hard daily, always on time at 7a and working despite the constant rain. No hiccups with inspections, crew cleaned up the place throughout the project and hauled all debris away after completion as well. Originally, I envisioned the project would run over price, take twice as long as promised to complete, and with multiple surprises. Virtually none of this turned out to be the case. After excavation, Steve mentioned that a water line and main gas line needed to be moved away from the perimeter in case of need for future repairs which I appreciated and took care of. Other than that, price was exactly as quoted, duration of project exactly as quoted. Would highly recommend and definitely use again if any foundation needs arose in the future.

This group is top notch, friendly and excellent. There was an issue with scheduling (for some reason they didn't get the deal I bought on the website) my wife had me call the day before the scheduled inspection (that I set up on the website) and alpha structural got back to me asap. Even though they were just notified that morning they got Dick out later that afternoon when we needed him. I was very impressed how they were able to make it right in such a short amount of time. Buying a home with potential issues (especially the foundation) is tough enough but for them making it work was a life saver. Dick our structural engineer was very knowledgeable, gave all the facts and in the end gave us piece of mind. I would definitely use them again!!
