"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!!"

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"Eran quickly responded to my inquiry regarding a load bearing structure of my home. He sent his structural engineer to determine if the structure was a load bearing problem. The engineer was able to determine 100% that it was not a load bearing structure. I would definitely recommend them to anyone who needs structural engineering solutions."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

"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."
