03 The Rare Combination
The industry makes you choose. Caston refuses.
Large contractor, or personal service. Corporate capability, or owner accessibility. Scale, or accountability. Every general contractor has been asked to pick one.
Big enough to handle the most demanding projects. Personal enough to still answer the phone.
Many of our largest competitors are owned by multinational firms whose executives have never set foot on a job site. At Caston, the person you reach has done the work, knows the project, and stands behind it.

06 What Holds It Up
Six things customers count on, in the order they matter.
01
Our People
Built by people you can count on.
Caston's reputation isn't built by a logo, a bid, or a brochure. It's built by the crews in the field, the project managers who pick up the phone, and leaders who have actually stood on the job site. When something matters, you don't get a call center. You get someone who cares as much as you do.
02
Trusted
Reputation earned. Never borrowed.
For over 70 years, Caston has earned trust one relationship at a time. Customers don't stay because of marketing. They stay because Caston consistently delivers.
03
Capable
The work others hesitate to take on.
When projects become technically demanding, when details become highly specialized, when others hesitate, Caston leans in. Not because they're fearless. Because they've learned how.
04
Accountable
The person you call owns the outcome.
Problems don't wait for committee meetings. At Caston, decisions happen close to the work. Customers don't navigate layers of bureaucracy. They reach people who know the project.
05
Committed
Partners until the job is done.
Caston doesn't disappear when challenges arise. They move toward them. Every project is approached with one philosophy: us and the customer versus the problem.
06
Built on Partnership
Everyone working toward the same goal.
When something unexpected happens, the question isn't whose fault this is. The question is how we solve it together. That's why customers keep calling.
07 In Their Words
The people whose reputation was on the line.
“The Stonegate Elementary Project has been deemed a huge success by both C.W. Driver and the Irvine Unified School District. These accolades are due in large part to Caston's excellence on the job. Your office and field stood out as one of the best Contractors. Period.”
“Caston has done a great job on this project, not only the scope of work was performed with no injuries but ahead of time. The building looks amazing. Kudos to you all.”
“Your team always performs and exceeds expectations. Dave and I never worry when we have Caston on our projects. Thank you for being a valued partner with Erickson-Hall.”
“Your firm is honest, intelligent and hard-working and it has been a real pleasure to work with everyone in your company. Thanks for a first rate experience.”
08 Safety
A safe job site isn't the one you think about. It's the one you never have to.
Every project runs on people, and every person has someone waiting for them at the end of the day. Caston has never believed a schedule is worth a shortcut.
For a general contractor, that isn't a nice-to-have. A safe subcontractor means fewer incidents, fewer delays, and fewer questions from the owner.
How We Work SafeWhen Caston is on the job, the job gets done.
Where capability and accountability exist together.
