I hired Cecilia and the team for a structural peer review on a residential beam and post project. They were responsive, professional, and easy to work with. Their review was clear and helpful, and they provided solid technical feedback that gave me confidence in the final design. Overall, a smooth and positive experience. I would gladly work with them again!

I really appreciate the honesty on them, I was concerned about some cracks that have developed over the last few years on my house and I called them for a foundation inspection. He explained that this arent worrysome based on their nature and in fact are pretty common on the bay area due to soil and left it up to me whether to still get a the inspection done or not. Thank you so much!
