About Us


Thornton Paving Inc. was founded by James T. Thornton in 1946 in Marin County, CA, and we have been operating out of the same physical location ever since. We try to make customer satisfaction our main priority and have thousands of happy customers in Marin County alone. We do most of our work in Marin but we do travel to Sonoma County, San Francisco, and the East Bay.

At Thornton Paving Inc. we are a qualified full service asphalt maintenance corporation. We have the resources and experience to effectively, efficiently and economically provide various services to you. A good paving, seal-coating, or line striping job begins with a plan. Before we start, we know your job from start to finish. A thorough site inspection permits us to become familiar with the specific conditions of your property and prevents costly surprises. When you receive a written proposal from Thornton Paving Inc. you’re getting more than just a proposal; it is a plan.

We have the knowledge, procedures and resources to ensure that the job is done correctly and on schedule.
