Custom Energy-Efficient Homes in Midcoast Maine
Island Carpentry has been dedicated to crafting energy-efficient and net-zero energy homes in Midcoast Maine since 2008. Our expertise lies in combining sustainable building practices with innovative design to create homes that produce as much energy as they consume. Located on Georgetown Island, we serve coastal peninsulas near Bath and Brunswick, as well as Portland and Freeport. Our team specializes in custom home construction, deep energy retrofits, and sustainable building solutions tailored to Maine's climate. We prioritize superior insulation, solar power integration, and advanced heating systems to deliver comfortable, low-maintenance living spaces. With projects like the Kelsey Brook Green Subdivision and Eco-Village One, we demonstrate our commitment to environmental stewardship and community-focused development.Our partnerships with architects and use of factory-built BrightBuilt Homes ensure precision and efficiency. Recognized for our technical expertise in super-insulated wall systems and heat recovery ventilation, we provide transparent, client-centric service from initial design to final construction. Our work has been featured in regional open houses and collaborations with the Midcoast Green Collaborative, showcasing the practicality of net-zero living. We remain dedicated to advancing energy independence while maintaining the aesthetic character of traditional Maine architecture.

Services
Net Zero Energy Homes
Our net-zero energy homes produce as much electricity as they consume through solar panels and ultra-efficient design. These homes feature R-45 wall insulation, R-58 roofs, and ductless heat pumps. We integrate heat recovery ventilation systems to maintain air quality while minimizing energy loss. Clients benefit from lower utility bills and reduced environmental impact.
Deep Energy Retrofit
We transform existing homes into energy-efficient spaces by adding 2" polyiso foam insulation, dense-packed cellulose, and air sealing. Our retrofits include upgrading rim joists and installing heat recovery ventilation systems. This service reduces heating costs by up to 50% while preserving structural integrity and historical character.
BrightBuilt Home Construction
We construct factory-built BrightBuilt Homes designed for energy efficiency and rapid assembly. These homes feature pre-insulated panels and modular components for precision. Clients receive high-performance homes with reduced construction timelines and minimized material waste.
Solar Power Integration
We install grid-tied solar electric systems with Canadian solar modules. Our designs optimize south-facing roof space for maximum energy production. Systems typically generate 7,000-9,600 kWh annually, offsetting 8,500 lbs of CO2 emissions while providing renewable energy credits.
Custom Home Design
We create custom-designed homes tailored to site conditions and client needs. Services include triple-glazed windows, slab-on-grade foundations with R-20 insulation, and pine shiplap siding. Our designs balance energy efficiency with aesthetic integration into Maine's coastal and forested landscapes.

Questions
What is a net-zero energy home?
A net-zero energy home produces as much electricity as it consumes through solar panels and ultra-efficient design, resulting in zero net energy bills.
Do you build homes outside Midcoast Maine?
While our headquarters are in Georgetown, we serve all of Midcoast Maine including Portland, Freeport, Bath, and Brunswick.
Can you retrofit existing homes?
Yes, our deep energy retrofit service upgrades existing homes with advanced insulation, air sealing, and energy recovery systems to dramatically reduce energy consumption.
What building methods do you use?
We use 2x8 wall framing with 2" foam board, dense-packed cellulose insulation, and 2x12 roof rafters with spray foam and cellulose for R-45 to R-60 insulation values.
How do your homes handle Maine winters?
Our homes use ductless mini-split heat pumps that operate efficiently down to -15°F, combined with superior insulation to maintain comfort in extreme cold.
Are financing options available?
We recommend exploring Efficiency Maine rebates and federal tax credits for energy-efficient home improvements to offset initial investment costs.
