Why Northern California Chooses Lee One Construction.
We are based in Anderson, which means our crew is on your site faster than any contractor commuting from outside the region. Monroe Lee is personally on every job, not a dispatched employee. That matters when you are dealing with Shasta County's clay-heavy soils, seasonal drainage patterns, and a county permit office that has its own timeline. A contractor who doesn't know this terrain adds days and dollars to your project. We know the ground, and we know the process.
One call to Lee One gets you excavation, septic, trenching, drainage, and more without subcontractor coordination delays. Our 24/7 availability is real, Monroe Lee answers, not a recording. We hold CSLB #1063228 and carry 25 years of Northern California field experience into every project we accept. When something urgent comes up on your property, we are the crew that shows up.

We had Lee’s One Construction fix multiple water leaks across our large parking area. The plan was made, they followed it perfectly and left the job site clean. I highly recommend using Monroe and his boys.

Lee One Construction owner Monroe Lee picks up the phone, was great to work with and had my septic system diagnosed, fixed and up in running in less than a week. I would recommend them as they do top notch work for a reasonable price.

It was a pleasure working with Monroe’s son and staff. They were conscious knowledgeable and efficient. They showed up on time did the work and cleaned up. You couldn’t even tell where they had dug the ditch across my gravel walkway. I would recommend them highly.
