Mr. Guy was on time for our Saturday appointment and exceeded my expectations with his thoroughness. He went under the house and reviewed my foundation, took pictures and showed them to me. I was very knowledgeable and friendly. He seemed honest when he told me my foundation did not have an cracks, but the current brackets, although stable are not up to today's code. I have an old house. When I'm ready to get the work done, I will consider them for sure. He did not charge me for the visit, which was substantial.

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.

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.
Description of Work: We had settling in a cantilevered wall in a kitchen remodel that was poorly constructed after the 1987 Whittier quake. Alpha assessed the problem, suggesting a much less expensive and invasive solution than another company.

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.

We decided not to do it but I thought they were really first class. They looked at our house and they gave us a bid. We just thought about it and decided not to do it. I really liked the person who came out. I thought he had integrity. He said you know I really wouldn't worry about it too much. Which was a little hint not that we were going to be ok but he didn't feel that we are that close to the Santa Anreas fault even though we are on beach property. I guess he was kinda indirectly saying when we told him it was a scraper - if anybody bought it they would scrape the house and build a castle- and we are in our 80's. We just didn't think that it would be worthwhile to spend that kind of money. Anyways I thought they were very honest and if we were going to do it we would use them. I think they know what they are doing. I would definitely refer them to a friend.

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.
Description of Work: Crippled/buckled wall at a small apartment building. We originally hired them to do the mandatory Earthquake retrofitting required by the City of Los Angeles for multi-family dwellings. In the meantime, while working on the plans and sign-offs from the city, I noticed a crippling/buckling wall at another property and called them immediately.

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!!

Excellently well! Sandy helped me coordinate the inspection expediently. We were on a tight timeline and she pulled some strings so we could get the inspection done in time.

They were efficient and pleasant to work with. They did the work on time, neat, no mess, and very good to work with. However, the final step is to have the city inspector come out and review the work that was done. My house has a very small crawl space and said Alpha Structural needs to come out and create better access to the crawl space before I can get a certificate of completion. I contacted Alpha and set up an appointment and that was the last I've heard from them. They missed the appointment and will not return my calls or emails. I've been calling 1-2 times every week for three months now.

I spoke with Lisa who was incredibly helpful and super efficient. They couldn't do the work I needed because they are a full service company (they do the construction as well) and I didn't need that. But she gave me a referral. Very nice and if I ever need to do a lot of work on my house I would use them.

Called and spoke to Lisa, do not really know who she is but maybe she is the owner. Asked her to get an estimate and a structural assessment on my house and her reply was "are you going to sell the house or not". When I asked her what that had to do with anything she became irate, rude, insulting and loud. She had a extremely bad attitude and even though I had already given her my phone number and address, I decided not to do business with that company. All the good reviews in here must be family, friends and completely FAKE. This company is a nightmare to even speak to, I can't imagine having to work with that woman or anyone else in there.

Hello [Member Name Removed], I apologize that you did not have a good experience when you called in. Lisa is our Customer Service rep that took your call. It is rare in the extreme (I believe that you are the first) that we have ever had someone give anything less than stellar feedback about Lisa, let alone the statements that you have made. She consistently is raved about due to the level of care she takes for each person that calls in as she goes above and beyond to set appointments for clients and help however she can. It is our company policy to obtain whether someone is buying or selling a property when talking with them as it changes the service that we provide. The reviews that we have here and on other sites are anything but fake. We work diligently to provide a service where we deliver more than our clients expect resulting in the Angie's List Super Service Award every year since 2009. If you would like to go over this with me I would be happy to discuss this with you personally to see how I can help you. Please feel free to reach out to me at 323-258-5482.

Adequate work. Untrustworthy management. Charged us 56k to do structural engineering and foundation restoration. Then told buyers for our property that we should have retrofitted at the same time we did the structural work. They told buyers it would cost another 20k. However, Charlie Rosenkranz who wrote two separate proposals for the work required on the building and who also advised the prospective buyers never recommended to us, either in writing or verbally that we should retrofit. Don't trust this company.

Response from Alpha Structural, Inc.
I never met or spoke with the woman who wrote this review. I did speak with her husband on numerous occasions, as he hired us to resolve a complex house hillside settlement issue. During one of those conversations, I said that the house could also use an earthquake retrofit, though it could get expensive because there was inadequate crawl space for men to actually get under a portion of the house and that we would have to dig tunnels under the floor of the house to increase the room to work. He bluntly told me that he didn't have unlimited resources to spend, so I did not press the issue any further or mention it again. I believe it's possible he doesn't remember that, as we had many conversations and many issues to resolve on this project. When the potential buyers asked us to come out (specifically because we were the ones who had done the work), we agreed. They specifically asked me about how much it would be to perform an earthquake retrofit. I gave them this information, but made it very clear in writing that this was 100% voluntary work. I never, ever said or even implied that the sellers should have done it but didn't. It's considered a voluntary upgrade. The buyers and their agent at that time were not at all upset with the sellers, but were very upset with the seller's agent, who they said was extremely rude and hard to work with (never met him, either). Perhaps it was that agent who told the sellers that I said they should have done the work but didn't, and that made them angry at me; I don't know. But I never said any such thing. We did all the work that we contracted for to a very good result, for the price agreed to, in a very professional manner. Charlie Rosenkranz VP Engineering Alpha Structural, Inc.

Douglas provided a structural assessment for a new home we just purchased. His attention to detail was great and comprehensive. The report was very thorough. Above all, I appreciate the honest objective opinions and recommendations so that I didn't feel like I had to go overboard on things. Was very helpful in spending time afterwards to answer follow up questions too. Excellent service.

I had been worried about some cracks in the walls in four areas of my house and I recently noticed that one of the overhead beams supporting my garage roof was warped. I was worried the overhead storage platform may be over weighted and causing damage. I set an appointment with Lisa at Alpha who was super helpful. Douglas arrived right on time and looked everything. Luckily nothing looked structural to him--just age and materials (the house was built in the 1950's). He spent the time to explain everything to me on what I was seeing and why there were cracks. He even suggested how we could straighten out the warped beam over time. It was a huge relief for me to know I did not have bigger problems.
