"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."

"Nice guys who know their stuff. Showed up right on time and didn't rush, even though there was no true "solution" to the issue at hand. If you want civil engineers, I would go with Standley."

"I hired CCD to help me permit a structure that I built (Rooftop Deck) and then had a neighbor complain about, leading to lots of trouble and compliance issues. After getting some quotes (that were often 2-3 times what I ended up paying) I found CCD. Mike told me they have never failed to permit a single unpermitted structure... and 12 months later mine is another one of their success stories. I had them draw up the plans and the city approved his blueprints without a single correction which I understand is rare in Santa Monica. I am very satisfied with everything CCD did for me & would not hesitate to hire them again."

"Jonathan responded to my request for a structural engineer within an hour. He was very professional and came to house to look at the project. Both Johnathan and Trina responded to my texts, calls and emails. Although this wasnâ t a large job, Jonathan gave me a bid and the completed project in two weeks. I wasnâ t sure who to contact, so I used Angi - Home Advisor and was connected with New Beginnings Engineering. I definitely recommend them if you need a structural engineer."

"Mr. Hoerner was great to work with. He took a lot of time with me on site to analyze the structure and discuss options with me. He also quickly answered my followup questions once he delivered the design."

"We had already had paid an architect and structural engineer to create blueprints. My plan was to contact 4 contractors to submit bids for the job. I found Goodfellas through Angie's List and they had a ton of great reviews, so I went to their website and requested a quote. In less than 24 hours they contacted me and we scheduled an appointment for the next day. I met with Danny and showed him the blueprints, and we talked about some other details that we wanted to see from the project. Danny was very patient and took a lot of time listening to my wants/needs, but also gave some great suggestions on how we could improve the look and feel of the home. After about an hour and a half, Danny provided me with a detailed quote and was on his way.
My wife and I continued to interview other contractors, but finally settled on Danny and his team. Once I let Danny know we were going to go with Goodfellas, he scheduled another appointment with us to go through the contract. This meeting was substantially longer than the first, but only because Danny is so detail oriented that he wanted to make sure that every possible piece of the project was covered in the contract. After settling all the details of the contract, we discussed start dates. Initially, Danny had promised to start about a week after the meeting, however, he called me later that night and said that they could start in a couple days.
Work started on 11/30/15. Danny was on-site the first day with his crew walking them through the various aspects of the project. I was not home at the time to meet all of them, but did get a chance to meet the Foreman, Rudy. Rudy and his team stayed well past sunset to get some concrete demo work done and were back bright and early the next morning to finish it up. By the end of the second day they had removed all the old concrete and had dug up the area where the new foundation will eventually be laid. I am very curious about how this process works and Rudy has been more than willing to take a few minutes to explain things to me.
The project is still on going, but I know Danny, Rudy and their team are going to continue to do great work.

"I have contacted Meir from t.n.l. construction and from the first meeting he show knowledge and professionalism.
Meir referred me to an architect and a structural engineer that t.n.l. works with I hired them and they also were very professional.
After the design was complete and we pull the permit i negotiated with t.n.l I got tow other quotes that not only were higher also the contractors did not show the professionalism that t.n.l showed.
We sign a contract and t.n.l started with the foundation than the rough and the final.
They ordered the long lead time items ahead of time in order not to delay the job.
Only in the last 2 weeks they demo the part that connect the addition with the existing house in order not to inconvenienced me.
The addition look beautiful and an integral part of the house.
T.N.L. were very professional and the kept the yard and the house clean.
All inspections passed the first time we call for."

"We had M & A Creative Construction tear down and replace the roof of our wood pergola and replace our termite eaten wood fence in the back yard. Mohammad did all of the work alone and in two days, eating his lunch at our patio table! He was on the property from 10:00 AM to 6:00 PM working the whole time. His work caught my eye, because he painted all of the 1x3 slats individually before he nailed them to the roof piece. On the fence, he removed the damaged 6ft panel and replaced it with the exact match from Home Depot. He also cemented its feet into the ground for added stability! When he was done with all of his work, he hauled away the old wood from the pergola and fence. He left the remainder of the paint with us for future touch ups. He was extremely professional and courteous!"
