About Herks Carpentry
We help homeowners from the South Shore through the Cape Cod make their homes work better,
look better, and last longer.
Some folks come to us with full blueprints. Others just have a rough idea and a Pinterest folder.
Either way, we’ve got you covered, and we’ll help you figure it out.
Where It All Started
Herks Carpentry was founded by Herk Costa, a guy who knows the value of hard work, and who believes construction should be personal.
He didn’t start in the trades. He started in restaurants, but the moment he stepped onto a job site, something clicked.
He spent the next decade learning the craft, mastering the details, and building relationships that still fuel the business today.
Ten years later, Herks Carpentry is one of the most trusted crews on the Cape, not because we chase every job, but because we focus on doing the right ones the right way.
“To me, building is about more than tools and materials. It’s about knowing that what we’re creating will be part of someone’s life. Part of their family, their memories, their future.” - Herk
What We Stand For
We’ve built this company on a few simple beliefs:
Respect
the home
We protect the floors, clean up daily, and leave it better than we found it.
Respect
the people
That means honest pricing, clear timelines, and no corner-cutting.
Take pride
in the work
Whether it’s a deck, a full home build, or a single bathroom, we do it with care.
Our Core Values:
We Are HERKS
These aren’t just words we stick on a wall. This is how we show up, every day, on every job.
Honesty
No games, just straight talk, fair pricing, and full transparency from start to finish.
Excellence
We don’t cut corners. Ever. Every joint, cut, and detail gets done the right way, because we actually care.
Reliability
We show up when we say we will. We stick to timelines. And we keep you in the loop the entire time.
Kindness
This one surprises people, but it matters. We treat your home, your time, and your family with respect.
Service
It’s not just about what we build, it’s about how you feel while we build it. Clean worksites, clear updates, and a crew that treats your home like their own.
