Our Comprehensive Insulation Services in Boston
Spray Foam Insulation: The Ultimate Performance Upgrade
Spray foam insulation is a powerful solution for creating a seamless air and moisture barrier, offering the highest R-value per inch of any common insulation material. We offer both open-cell and closed-cell options to meet the specific needs of your project.
- Ideal for Boston: Basements, crawl spaces, attics, and new construction in neighborhoods like the Seaport. Closed-cell spray foam is particularly effective in coastal areas and for preventing moisture issues in historic brick basements.
- Boston Application: In a South End brownstone, we use closed-cell spray foam on the basement walls to create a waterproof, airtight barrier, preventing moisture from the old foundation from entering the home and creating a warm, dry living space.
- Benefits: Maximum energy efficiency, superior air sealing, moisture and vapor barrier, adds structural rigidity.
Blown-In & Dense-Pack Cellulose: The Historic Home Solution
Cellulose insulation is an eco-friendly, high-performance material made from recycled paper. It is treated for fire and pest resistance and is the ideal solution for retrofitting older homes with empty wall cavities.
- Ideal for Boston: The walls of triple-deckers, Victorians, and colonial homes. It can be installed with minimal disruption, preserving original plaster and lath walls.
- Boston Application: For a triple-decker in Dorchester, we use the dense-pack technique to blow cellulose into the empty wall cavities from the exterior. This process fills every gap, creating a continuous thermal blanket that dramatically reduces drafts and energy loss without any interior demolition.
- Benefits: Excellent thermal resistance, superior sound dampening (ideal for multi-family living), eco-friendly, and minimally invasive.
Mineral Wool Insulation: For Fire Safety and Sound Control
Mineral wool (or rock wool) is a high-performance insulation material known for its exceptional fire resistance, moisture resistance, and acoustic properties. It is an excellent choice for multi-family buildings and commercial projects.
- Ideal for Boston: Multi-family buildings, condos, and commercial spaces where fire safety and sound control are paramount.
- Boston Application: In a new condo development in the North End, we use mineral wool insulation in the walls and floors between units to provide superior fire protection and to create a quiet, private living experience for residents.
- Benefits: Highly fire-resistant, excellent sound absorption, moisture resistant, and dimensionally stable.
Fiberglass Insulation: The Reliable Standard
Fiberglass insulation is a classic, reliable, and cost-effective insulation solution. Modern fiberglass products offer excellent thermal performance and are available in batts, rolls, and loose-fill forms.
- Ideal for Boston: Attics, new construction, and additions where wall cavities are open and easy to access.
- Boston Application: For a home in West Roxbury undergoing a major renovation, we install high-density fiberglass batts in the open walls and use blown-in fiberglass to create a thick, even layer of insulation in the attic.
- Benefits: Cost-effective, reliable performance, widely available, and non-combustible.
Air Sealing & Fire Blocks: The Critical First Step
No insulation project is complete without comprehensive air sealing. Air leakage is the number one source of energy loss in most homes. We use advanced techniques to find and seal every hidden gap and crack before any insulation is installed.
- Ideal for Boston: All homes, but especially older homes with years of settlement and construction quirks.
- Boston Application: Before insulating the attic of a Charlestown rowhouse, our team meticulously seals all penetrations—around plumbing stacks, electrical wires, and chimneys—to prevent warm air from leaking into the attic, the primary cause of ice dams.
- Benefits: Eliminates drafts, improves insulation performance, reduces energy bills, and prevents moisture problems.
