The People Behind the Work

A family-owned construction company in Fullerton

Your home is personal. The way we plan, communicate, and build should reflect that.

Engineering experience. A homeowner’s perspective.

KoBolt Construction is led by founder Nelson Moreno, who holds a master’s degree in civil engineering and is a Certified Construction Manager (CCM). His background includes major projects in Los Angeles and Orange County, as well as the practical coordination of the trades that bring a building together.

That experience shapes our approach to residential work: understand the existing home, ask detailed questions, and plan how the work will be built before construction begins.

Our purpose

Help homeowners make confident decisions and create spaces that serve them well. We aim to earn your trust through careful work, clear explanations, and follow-through—not promises that a complex project will be effortless.

Safety is part of the work

We encourage every team member to speak up about unsafe conditions. Planning the work, looking after the site, and communicating concerns are part of how we protect the people involved in your project.

A team that takes pride in the details

Nelson started KoBolt to create a more personal customer experience and a workplace where people feel appreciated. Respect for our team and pride in their craft are reflected in how we approach your home.

Accountability you can see

We explain the scope, discuss changes, and keep you informed as the project develops. We treat your home with care and stand behind our work after the final walk-through.

Why Nelson started KoBolt

After years working for heavy civil contractors, Nelson wanted to build a different kind of company: a family-owned business where homeowners could speak directly with the people responsible for their project and team members could do work they were proud of.

Today, KoBolt focuses on major home remodels, additions, and ADUs. The work ranges from the structural changes behind an open living space to the tile, cabinetry, and finish details you use every day.

The same values guide projects large and small: understand the homeowner’s needs, communicate honestly, respect the property, and take responsibility for the result.
