You Know That Project You’ve Been Talking About for Years? Let’s Do It!
You’ve probably talked about this project for a while now, maybe even longer than you’d like to admit.
And if you’re here, you’re finally ready to do something about it.
Whether you're planning a new build, reworking the space you’ve outgrown, or just want things to feel right again, we’d be glad to help.
We’re a local crew serving the South Shore and Cape Cod that respects your home like it’s our own and shows up ready to work every day, without you having to chase us down.
Here's What We Do
New Construction
Building a home from the ground up is a big deal, and we don’t take that lightly. From land prep to final finishes, we handle every part of the build with care, craftsmanship, and constant communication. You’ll always know where things stand, and what’s coming next.
Thinking about a new build?
Additions
Running out of space? We’ve built everything from in-law suites and master bedrooms to home offices and second-story expansions. We’ll help you create more room without making it feel like an afterthought.
We’d love to help you plan your new space.
Remodeling
Whether you’re updating a tired kitchen, modernizing your bathroom, or reworking an entire floor, we’ll help you make it better. We handle everything: cabinetry, trim, windows, doors, roofing, siding… all with the level of detail we’d expect in our own homes.
Got a space that needs an update?
Decks & Exteriors
A good deck should feel like a natural extension of your home. A place you actually want to spend time. We build clean, solid, weather-ready outdoor spaces you’ll be proud to show off.
Let’s build the kind of deck you’ll actually use.
Design & Consulting
Not sure where to start? We’ll walk you through what’s possible, what makes the most sense for your space and budget, and what to expect next. We’ll even let you know if you’ll need an architect, engineer, or survey, and help you get it lined up.

Some of the Work We’re Proud Of
Every project is different, but our goal is always the same - to build something our clients can feel proud of.
Here’s a small sample of the homes, remodels, and additions we’ve helped bring to life.
Meet the Guy
Behind the Crew -
Hercules Costa
Herks Carpentry started with a simple mindset: do good work, treat people right, and build things that last.
Before starting the company, Herk Costa worked in restaurants, but it was on the job sites where he found his rhythm. He spent over a decade learning the craft from the ground up, then took the leap to start his own company. That was 10 years ago. Since then, he’s built a team that takes pride in doing things the right way.
For Herk, building has always meant more than wood and nails. It’s about creating spaces where families grow, memories are made, and futures take shape.
“I’d look at an empty lot and think, someday, kids will be playing in that yard. That mindset still drives everything we do.”
If you’re looking for a contractor who cares about the big picture and the little details, Herk’s your guy.
Proudly Serving the South
Shore and Cape Cod
We work with homeowners and architects from the South Shore through the Cape Cod.

Not sure if we cover your area? Just ask (we probably do).
For Architects Who
Want a Builder
That Gets It
We know how frustrating it can be when your design doesn’t get built the way you intended.
That’s why we partner with architects who care and who want their work carried out with precision, professionalism, and pride.
We follow plans. We hit deadlines. We ask the right questions early so there are no surprises later.
And we make sure your clients feel like the whole thing is under control, because it is.

Everything You’ve Been Wondering
(And a Few Things You Probably Haven’t Asked Yet)
How much will my project cost?
It depends on the size, scope, and materials, but you’ll always get a clear, personalized estimate upfront, with no surprises later. We’ll walk through options based on your budget.
What if something goes wrong during the project?
It’s construction - things come up. But here’s the difference: we don’t disappear, dodge your calls, or shift blame. We fix it. Quickly, clearly, and at our cost if it’s our mistake. That’s how we keep our reputation (and sleep at night).
Do I need to hire an architect or engineer?
Sometimes, yes. We’ll let you know right away if your project requires one, and we can recommend local pros we trust if you don’t have someone in mind.
What happens if we change our mind about something mid-project?
It happens. And we’ll walk through the options with you - what it changes, how it affects the timeline or price, and whether it’s even worth doing. No pressure. Just honest advice from people who’ve seen it all.
Can I live in the home during the work?
In many cases, yes, especially for remodels and additions. We’ll work with you to make it as comfortable and disruption-free as possible.
Can we trust your crew to be in and around our home?
100%. We don’t use random subs off Craigslist. Our crew is uniformed, professional, and respectful. Many of our clients are home during the work, some even leave us a key.
Are you licensed and insured?
Yes, fully licensed and insured in Massachusetts. We do things by the book and take safety seriously.
Do you clean up after the job?
Every day. And again at the end. We even bring in a pro cleaning crew after larger jobs so your home looks as good as it feels.
Still have questions?
Ready to Finally Get It Done Right?
Whether you’re planning something big or just kicking around ideas, we’d love to hear what you’re working on.
No pressure, no pushy sales talk. Just an honest conversation about what’s possible and what it’ll take to make it happen.
