What our customers are saying about us
Managing one of the largest condo complexes in Los Angeles, CAS is a company to rely on. CAS is responsive and comprehensive in dealing with both large and small-scale projects. CAS completed the resurfacing of common area walkways, while being accommodating to the residents and still completed the project on time and within budget. I highly recommend CAS to anyone who wants a company that provides the human aspect to any project.
Elvin H. - Century City, Los Angeles, CA
Jesse and CAS did a great job for us on a project involving concrete repair, painting, stucco repair and waterproofing. They're great to work with and we would definitely use them again!
William Edwards
In the years 2019 and 2020, we purchased 5 buildings in the Los Angeles area. For the remodeling, we wanted to find a general contractor to work with us on all buildings. After a long search, we found CAS. It has been a great relationship. They had done all the remodeling for our properties. We love the professionalism, expertise, communication and all in all, are very happy.
Gilad S - SoMa, San Francisco, CA
CAS installed waterproofing for an HOA. They were tenacious on any punch items and leaks reported and fixed anything that was requested of them. You can not ask more from a company. They stood behind their subs and work during and after the entire construction process. This lead to us including them on our bid list for other projects.
Mark Shear
Highly recommended. I had an outdoor stucco wall broken from top to bottom by tree roots and I contacted CAS based on previous reviews. They responded promptly to my request, asked for photos, sent someone to assess the repair needs in person and promptly sent me an estimate and proposal. Work started within a couple of days after I signed on. Work was done efficiently in a few days and looked better than it had before the wall was broken.
Patti K. - Simi Valley, CA
Jesse been on track and honest about his work. Our project was quite large with the removal or the whole upper deck loading dock and he got it done a the most reasonable price. He knows his waterproofing and more.
Bonny Tsang
I can say that I have not worked with a more honest contractor in my 20+ years in the business. CAS's team was always punctual, transparent, candid, and fair across the board on all accounts. Happily, I can now say that I have found my last contractor as I will only work with CAS and I highly recommend anyone in the Greater Los Angeles area do the same! Thank You, CAS!
To many more successful years together.

I could not be happier that we decided to use CAS for our driveway and porch. We did get a cheaper estimate from another company which I sent to CAS. As Jesse pointed out the other estimate was not complete and he was correct. We have a gigantic driveway on a hill and a septic tank under the driveway.I was so impressed with the team. First of all Danny came out 2 times to measure and was very patient with me as I kept adding and taking things from the job. The team was so great!!!
Sweet P V. - Pasadena, CA
