Who you're hiring

Troia is owner-operated. Robert Amarin is on every job. No layers of project managers, no subcontracted oversight, no middleman markup.

From the first site walk to final inspection, you deal directly with the licensed builder responsible for your project. That means faster decisions, tighter cost control, and craftsmanship we put our name behind.

"We don't manage builds from a desk. We frame it, pour it, and stand behind every wall we raise."

What we build

Three ways we put the license to work.

Accessory Dwelling Units

Garage conversions, attached and detached ADUs, and room additions, with permitting, coastal overlays, and utility tie-ins handled start to finish.

03

Structural Framing

Framing is the one trade we self-perform, and the only standalone scope we take on. As a licensed General B contractor, our own crews raise the structure your entire build depends on, square and plumb to engineered plans.

Preconstruction

Every build begins at the table.

Before a single board is cut, we sit down over the plans, aligning scope, budget, and schedule so the build runs clean from day one. It's how we protect your timeline and your investment.

We couldn't be happier with our new kitchen! Troia was professional from start to finish. Robert was thorough and transparent when explaining each step. He’s extremely intelligent and creative, suggesting ways to save money and improve on our ideas at the same time. With his connections we were able to save a ton of money on materials. The crew arrived on time every day. They kept a clean job site and finished exactly on schedule. The craftsmanship is top-notch. Highly recommend! I’ve worked with a lot of construction companies and Troia is second to none!

I reached out to several contractors and construction companies for quotes on renovating my ADU. (Most of which took forever to get back to me) A friend recommended Troia Construction, and the recommendation held up. They stood out as the most efficient by far. clear, detailed quotes. Direct, non vague communication. Timelines were solid and realistic. And the one thing I appreciated the most was how detail oriented these guys were. Their confidence came through in both their process and delivery. Highly recommended!!

The quality of their work truly stands out — everything was done with precision and care, and the final result exceeded my expectations. It’s clear they take pride in what they do and value customer satisfaction. I would highly recommend Troia Construction to anyone looking for a trustworthy and top-quality construction company.

Troia Construction was professional, communicative, and easy to work with throughout our backyard project. The quality of their work met expectations, and everything was completed efficiently, I’d recommend them if you’re looking for a reliable contractor.
