Who we are

NorCal Exterior was founded by Byron Stocum, a licensed California contractor (CSLB #1103196) who's spent his career on the North Coast. The work we take on reflects what Byron and our team care about most: doing exterior projects that add life to your home and your family. He knows how much it matters to communicate clearly through every discovery and change on a project, with documented change orders so nothing gets done without your notice.

This is the most consistent feedback we get: "Communication was stellar." "Walked me through any new discoveries." "Always left a clean work site." If you read our reviews, you'll notice those phrases come up over and over. They're the parts of the job we work hardest at.

What we focus on

Exterior work, done with the same care as the inside of the house.

Siding is our specialty, but the projects we take on rarely live in one trade. We handle the full envelope so flashing, trim, and weather barriers integrate correctly the first time.

01

Craft over speed

We can move fast when the project calls for it, but we don't cut corners on prep, flashing, or finish work to hit a faster timeline. The parts of a siding job that determine whether it lasts are the parts you don't see.

02

Communication is the work

We keep clients informed throughout every project. When something unexpected surfaces, and it always does on remodels, we walk you through what we found, what the options are, and what each one costs before we proceed.

03

Materials matched to conditions

Coastal Humboldt is a demanding environment. We help clients pick siding, fasteners, and finishes that hold up to the salt air, fog, and rain, not what's cheapest or easiest to install.

04

Local, present, accountable

We live here, our shop is on Samoa Boulevard in Arcata, and our reputation is in this town. We answer the phone after the job is done, and we show up if something needs attention.

More than siding

Exterior is the focus. The skills run deeper.

Specialty
Siding · Decks · Windows
Experience
Full-house remodels

While siding and exterior work are our specialty, our experience runs through framing, finish carpentry, electrical, & plumbing. That breadth matters when an exterior project surfaces something unexpected behind the wall, since we can handle it without adding a parade of subcontractors to your project.
