Green Home Remodeling & Renovations in Boise, Idaho
Renovations and additions are a fantastic way to enhance the beauty, functionality, and value of your home while dramatically improving its environmental performance. Whether you're looking to update an older property, create more space for your growing family, accommodate multi-generational living, or simply reduce your energy bills, green remodeling can offer numerous benefits.
At EarthCraft Construction, we bring the same commitment to sustainability, energy efficiency, and healthy materials to remodeling projects as we do to new construction. We transform existing buildings into high-performance structures with new, invigorated, ultra-useful, high-performance envelopes.
H2: Why Green Remodeling?
Energy Cost Reduction
Older homes often have minimal insulation, leaky windows, and inefficient systems. Green remodeling can reduce energy costs by 30 to 60 percent through envelope improvements and system upgrades.
Improved Comfort
Drafty rooms, cold floors, and hot spots disappear when you improve insulation, air sealing, and HVAC systems. Your home becomes consistently comfortable throughout.
Healthier Indoor Environment
Old materials may contain VOCs, formaldehyde, or other harmful substances. Green remodeling replaces these with low-toxicity materials and improves ventilation for healthier indoor air. We spend 54 years of our lives inside our homes. That indoor environment matters.
Extended Home Lifespan
Upgrading building systems, improving moisture management, and using durable materials extends your home's useful life by decades.
Increased Property Value
Energy-efficient homes command premium prices. The improvements pay for themselves in reduced operating costs and higher resale values.
Environmental Responsibility
The greenest building is often the one already standing. Remodeling existing homes reduces waste, preserves embodied energy, and avoids consuming new land.
Our Approach to Green Remodeling
Every building, client, and property is different, as are the design considerations given to each of those individual aspects. Whether it's a single-family residence or a large commercial structure, EarthCraft is committed to the efficiency and success of your project.
We start by understanding what problems need solving. Is it energy costs, comfort, space, or function? What are your goals and values? What's your budget and timeline? What's worth preserving versus replacing?
Then we develop a comprehensive plan that prioritizes improvements based on costeffectiveness and your specific needs.
Building Envelope Improvements
Insulation Upgrades
Many older homes have R-11 or less in walls, R-19 in attics. We can upgrade to R-30 or better walls and R-50 or better attics using blown cellulose, dense-pack cellulose, or spray foam. When we use spray foam, we prefer soy-based options to reduce VOCs compared to conventional spray foam insulation.
Air Sealing
Controlling air leakage can reduce energy costs by 15 to 30 percent. We seal gaps around windows, doors, penetrations, and at the foundation and attic interfaces. This seals potential leak points and provides a direct thermal barrier.
Window & Door Replacement
High-performance windows with low-E coatings and insulated doors dramatically reduce heat loss and improve comfort. We specify windows with U-factors of 0.25 or better.
Roof & Attic Improvements
Proper attic insulation and ventilation prevents ice dams, reduces cooling costs, and extends roof life.
Foundation Insulation
Adding insulation to basement or crawl space walls improves comfort and reduces heat loss through the foundation.
Systems & Mechanical Upgrades
HVAC Replacement
Modern high-efficiency heat pumps use 30 to 50 percent less energy than older systems. We right-size equipment based on your home's improved envelope performance.
Water Heating
Heat pump water heaters, tankless water heaters, or solar thermal systems reduce water heating costs by 30 to 60 percent.
Ventilation
Tighter homes require proper ventilation. We add energy recovery ventilators or heat recovery ventilators that bring in fresh air while retaining energy.
Lighting
LED lighting uses 75 percent less energy than incandescent and lasts 25 times longer. It's a simple, cost-effective upgrade.
Electrical
Upgrading electrical panels prepares your home for electric vehicle charging, solar panels, and all-electric heating and cooling.
Healthy Materials Selection
Low-VOC Paints & Finishes
Conventional paints off-gas volatile organic compounds for months. We use low-VOC or zero-VOC paints, stains, and finishes throughout. This greatly reduces VOCs compared to conventional materials.
Formaldehyde-Free Materials
Many cabinets, composite wood products, and insulation contain formaldehyde. We specify formaldehyde-free alternatives.
Natural Flooring
We prefer real wood, bamboo, cork, or natural linoleum instead of vinyl that may contain phthalates or other chemicals.
Non-Toxic Adhesives
Low-VOC construction adhesives, caulks, and sealants go throughout the project.
Moisture Management
Proper ventilation, moisture barriers, and material selection prevent mold and maintain healthy indoor air quality.
Sustainable ADU Materials
Reclaimed & Recycled Materials
Where appropriate, we incorporate reclaimed wood, recycled metal, recycled glass tile, and other materials with recycled content.
Reclaimed & Recycled Materials
Where appropriate, we incorporate reclaimed wood, recycled metal, recycled glass tile, and other materials with recycled content.
Locally Sourced Materials
Reducing transportation distances lowers embodied energy. We source locally when possible.
Durable Materials
The most sustainable material is one that lasts. We choose materials proven for longevity rather than those requiring frequent replacement.
Certified Wood Products
FSC-certified lumber ensures responsible forest management.

The Remodeling Process
Phase 1: Assessment (1 to 2 weeks)
Home energy audit (optional but recommended), identify performance issues, understand your goals and budget, and develop preliminary recommendations.
Phase 2: Design & Planning (2 to 4 weeks)
Detailed design and material selection, cost estimating, permitting if required, and scheduling.
Phase 3: Construction (varies by project)
Careful protection of existing areas, phased construction to minimize disruption, quality control throughout, then final inspections and cleanup.
Phase 4: Verification (optional)
Blower door testing to verify air sealing, infrared imaging to check insulation, and energy modeling to project savings.
How Much Does Green Remodeling Cost?
Costs vary dramatically based on project scope:
Minor bathroom remodel: $15,000 to $30,000
Major kitchen remodel: $40,000 to $80,000
Whole-home energy upgrade: $30,000 to $60,000
Addition (500 to 1,000 square feet): $125,000 to $250,000
Return on Investment
Energy upgrades have 5 to 15 year payback through utility savings. Kitchen remodels recover 60 to 80 percent of cost at resale. Bathroom remodels recover 60 to 70 percent. Additions recover 50 to 75 percent depending on market.
When coming to an estimate for a remodel, it's less about the square footage than it is about how the work is done. We offer long and short term cost-saving solutions to make your green remodel a reality. Our cost-plus transparent pricing means you know exactly where money goes. No hidden markups.

Green Remodeling Questions
Can you improve energy efficiency without major renovations?
Yes. Air sealing, attic insulation, LED lighting, and smart thermostats provide significant savings with minimal disruption.
Should I remodel or rebuild?
If the structure is sound and layout is workable, remodeling is almost always greener than demolition and rebuilding. We can help you evaluate. The greenest building is the one already standing.
Will remodeling disrupt my life?
Some, yes. We minimize disruption through careful planning, phased work, and protecting occupied areas. Many projects allow you to stay in your home.
How long does a green remodel take?
Kitchen remodels take 4 to 8 weeks. Bathroom remodels take 2 to 4 weeks. Wholehome energy upgrades take 2 to 6 weeks. Additions take 3 to 6 months.
Do I need permits for energy upgrades?
Depends on scope. Simple insulation and air sealing usually don't. HVAC replacement, electrical work, and structural changes typically do. If you would like, we can assist you through the complete approval process, including permits and local building criteria.
Can you match the style of my older home?
Absolutely. We can improve performance while preserving or matching historic character and architectural details.
Can you add passive solar to an existing home?
Some elements can be added (better insulation, strategic windows, thermal mass) but true passive solar requires orientation and design from the beginning. Remodels offer opportunities to improve performance even if perfect passive solar isn't possible.
What about using straw bale in remodels?
While whole straw bale walls are typically for new construction, we can incorporate straw bale principles and materials in some additions and major renovations. We evaluate each project individually.
