Jerick and staff at ProStruct were Champions of Customer Service! When I called needing some…read moreEngineering work (Structural Calculations), I also needed an Architect to lead the project. Jerick was able to connect me with a fantastic Architect, Carlos at Zamudio Architecture. Carlos was very detailed and transparent with his work; it was a positive reflection of the kind of people ProStruct Engineering refers. I will definitely be working with ProStruct and Zamudio Architecture on the next project because I feel I can trust their expertise and transparency.

I had a great experience with Keystone Structural Engineers. I needed a structural inspection on…read moreshort notice, and they were able to fit me in quickly. Mehdi showed up on time and did a thorough job, he checked the roof structure (my main concern) and also looked over the foundation and other key areas. I got the stamped report the next day. Overall, the service was quick, professional, and fairly priced. I'm really happy with the experience and would recommend them.

Highly recommend! I found Keystone on Yelp to look at a small crack in my outdoor foundation, and…read morethe process was seamless. Scheduling with Clair was incredibly fast--it only took about 2 minutes to set up a general inspection. Julia, my inspector, was fantastic. She was professional, knowledgeable, and very patient with all my questions. After a thorough walkthrough of both the inside and outside of my home, she explained that the foundation itself is fine--the cracks were just poorly mixed surface cement that needs repatching. She even caught two other issues during the walkthrough that I wouldn't have noticed otherwise. I really appreciate the honesty and the extra effort. Great experience!

I hired A1F1 for a small project first (removing two columns in the front of my house to make a…read morenice sit-down patio). Fast, efficient, quality work that flew with high flying colors through the City Permits Department in one pass. I was impressed by them in all the ways our project worked out and hired them again for a very consequential project. Their thoroughness impressed me and my contractor ("These guys sure are covering all the bases brilliantly", he said of them). We wanted to lift up the ceiling of our kitchen and family room. Because the previous framing work was lacking and because we recently replaced our roof and installed a solar system with increased wind exposure, A1F1 explained we needed to install a big beam with a pier in concrete under the house. They provided all the drawings and calculations documentation needed for the City to approve again at first pass. Work is now under progress, and I have been at awe on how everything is working totally like clockwork. Highly recommended!

I was looking for a structural engineer to remove a wall between my kitchen and family room, I had…read morecalled various engineers ( including one that I had worked with in the past) and they all wanted a tremendous amount of money just for a site visit to advise whether it's even possible to remove the wall.. Anthony, from A1F1, took time out of his busy schedule to come out and look for almost no cost. He was on time, professional, and extremely knowledgeable. He actually advised me about another wall bordering my kitchen, and told me I could remove that wall since it wasn't load bearing. So now, I will remove 2 walls, and have a totally open floor plan. Can't say enough about the guy. If you are looking for a structural engineer, believe me, u won't get a better value.
