See what customers say about us
CS Engineering is a full-service civil and structural engineering firm with a difference—and it shows. But what we’re most proud of is the trust and satisfaction our clients share about working with us.
I recently had the need to have an existing deck and roof certified as structurally sound and not impacting my house it's attached to. It was an urgency needed for a refinance I was going. Not only was Carson able to do that the same day I called him, but also was helpful in applying for a flood certificate for the property. He is not only reliable and fastidious in getting the job done, he is a man of his word. Need a structural engineer? Carson is the one you need

There is NO firm that comes close to the level of professionalism, knowledge, service, and expedience as CS Engineering. So thankful that I found Carson and CS Engineering and have recommended him to many colleagues and clients.
As a general contractor it is extremely hard to find an engineer who, to put it bluntly, can speak to you like a human being. Carson not only does that but he also answers his phone and emails in a timely fashion. He has always been available for questions, concerns and general feedback back on his designs. I cannot recommend him more.
