Built for the Coast.
Built to Last.
From custom homes on the Maine shoreline to renovations in coastal Massachusetts, Coastal Custom Homes brings unmatched craftsmanship and decades of New England building expertise to every project.
New England Builders. Built Different.
Coastal Custom Homes was founded on a simple belief: that building someone's home is one of the most significant undertakings a contractor can take on — and it deserves to be done with integrity, precision, and genuine care.
Our founding owners together have built more than 1,000 homes across coastal Maine, New Hampshire, and Massachusetts. They know what it takes to build in this climate — the freeze-thaw cycles, the salt air, the strict coastal setback requirements, the exacting energy codes — and they've developed systems and partnerships that consistently produce results that hold up for generations.
We are a fully licensed and insured general contracting firm operating throughout the Seacoast and beyond. Every project is led by an experienced project manager, every subcontractor is vetted, and every build is backed by our commitment to transparent communication from groundbreaking to move-in.

Your Vision. Our Expertise.
Building a custom home on the New England coast requires more than standard construction knowledge. It demands an understanding of coastal regulations, extreme weather resilience, energy performance, and the craftsmanship to execute at a high level — every time.
We've built oceanfront shingle-style estates in southern Maine, modern coastal retreats in the New Hampshire Seacoast, and traditional New England farmhouses across the North Shore. Each one built to the exacting standards that 1,000+ homes of experience produces.
We work with your architect and interior designer, or can connect you with trusted design partners we've worked with for years. Either way, you have a single, accountable builder driving your project forward.

Respect the Old. Embrace the New.
New England homes carry character that's worth preserving. Our renovation approach starts with understanding what makes your home special — then building a plan that enhances it rather than erasing it.
We've renovated historic capes, colonial-era farmhouses, seaside cottages, and mid-century moderns. We know where to modernize, where to restore, and how to make old bones perform like new construction without losing what drew you to the home in the first place.
From full-gut kitchen and bathroom remodels to whole-home renovations that touch every system, we manage every trade and every detail with the same rigor we bring to new construction.
- Full-home renovations
- Kitchen & bath remodels
- Historic home restoration
- Energy efficiency upgrades
- Structural improvements
- Systems modernization
- Interior & exterior work
- Seasonal cottage upgrades
Add Space. Add Value.
An accessory dwelling unit or a well-designed addition is one of the smartest investments a homeowner can make — adding functional living space, increasing property value, and in many cases creating income potential.
We have extensive experience navigating the zoning and permitting requirements for ADUs and additions across Maine, New Hampshire, and Massachusetts — regulations that vary significantly by municipality, especially in coastal zones and historic districts.
Whether you're adding a connected in-law suite, a detached guest cottage, a primary bedroom addition, or a garage with a living space above, we design and build with the goal of making it feel like it was always part of the home.
- Detached ADUs & cottages
- In-law & family suites
- Garage apartments
- Primary bedroom additions
- Mudroom & entry additions
- Second-story additions
- Sunrooms & three-season spaces
- Zoning & permitting expertise
The Difference Experience Makes
A thousand homes doesn't just mean a thousand completed projects. It means a thousand problems solved, a thousand lessons learned, and a thousand families who trusted us with the most important building of their lives.
Coastal Construction Expertise
We build in one of the most demanding environments in North America. Salt air, coastal storms, frost heave, high wind loads — we've designed our building systems specifically for the New England coast. Your home will be built to last, not just built to code.
Unmatched Owner Experience
The founding partners of Coastal Custom Homes have built over 1,000 homes between them. That depth of experience shows in how we anticipate problems before they arise, how we manage complexity, and how we make decisions under pressure.
Total Transparency
Hidden costs and missed timelines are the hallmark of bad builders. We provide detailed project schedules, open-book budgets, and proactive communication so you're always in the loop — not waiting on a call that never comes.
Vetted Subcontractor Network
We've spent decades building relationships with the best tradespeople in Maine, New Hampshire, and Massachusetts. Our electrical, plumbing, HVAC, and finish trades are not random bids — they're trusted partners who share our commitment to quality.
Single Point of Accountability
You have one contact, one contract, and one team responsible for your entire project. No finger-pointing between trades. No confusion about who's responsible. We own the outcome from groundbreaking to final walkthrough.
Energy & Performance Focus
We build tight, efficient homes that perform exceptionally in New England's demanding climate. From air sealing and insulation to heat pump systems and solar-readiness, we build for the next 50 years — not just the next inspection.
Built on Trust
We built our dream home on the Maine coast with Coastal Custom Homes, and the process exceeded every expectation. They were proactive, honest about costs, and the craftsmanship is extraordinary. Five years later, the house still looks and performs like day one.
We hired Coastal Custom Homes for a full renovation of our 1890s Victorian in Newburyport. They respected the history of the house while completely modernizing the systems and layout. The team was meticulous, communicative, and genuinely cared about getting it right.
Our ADU project in Portsmouth came in on budget and on time — something everyone told us wouldn't happen. The team navigated a complicated zoning situation and delivered a beautiful detached cottage that's been rented every week since we finished it.
