Insulation & Air Sealing

Air sealing is a crucial step for Bay Area homeowners looking to enhance their HVAC system's efficiency, ensuring that conditioned air stays inside while preventing unwanted drafts and moisture infiltration.


Air sealing is a crucial process that involves sealing gaps and cracks in your home’s envelope to prevent air leaks. By effectively sealing these openings, you can significantly enhance the efficiency of your HVAC system, ensuring that heated or cooled air remains inside your home where it belongs. This not only improves indoor comfort but also reduces the workload on your HVAC system, leading to lower energy costs.
When air sealing is combined with proper insulation, the benefits multiply. A well-sealed home maintains a consistent temperature, reducing the need for constant heating or cooling. This synergy not only enhances comfort but also contributes to a healthier living environment by minimizing drafts and humidity fluctuations. Investing in air sealing is a smart choice for Bay Area homeowners looking to optimize their energy efficiency and create a more sustainable home.

1

Why Insulation Matters

Poor attic insulation allows heat to escape in winter and traps excessive heat in summer—leading to discomfort and high energy bills. Upgrading your attic insulation can reduce heating and cooling costs by up to 40% and improve year-round comfort.


2

Our Proven Process

We thoroughly inspect and test your attic, then air seal leaks, seal and insulate ductwork, and install the proper insulation level tailored to your home for maximum efficiency.


3

What we Include

Our comprehensive service includes attic duct encapsulation, air sealing (including hatches, recessed lights, and major gaps), sealing vented knee walls, using cellulose insulation, and converting your attic into a conditioned space.


Wall Insulation



Wall Insulation

Unlike attics and crawl spaces, wall cavities in existing homes are harder to access since they’re located behind drywall and exterior siding. However, insufficient wall insulation can significantly impact your home’s energy efficiency and indoor comfort. At Premier Eco Builders, we upgrade wall insulation by drilling small holes between each stud and densely packing the cavities with cellulose insulation. Once installed, we use infrared imaging to ensure complete and consistent coverage throughout.

Cellulose Blown-In Insulation

Blown-in cellulose insulation is an eco-friendly material made from recycled content and treated for fire resistance. It’s an excellent choice for topping off attic insulation or dense-packing enclosed spaces like wall cavities. Dense-pack cellulose not only improves thermal performance but also offers added protection against fire, pests, and mold. Treated with boric acid, this insulation helps repel insects and rodents, making it a long-lasting and reliable solution for your home.


Crawlspace Insulation









Often overlooked, the crawl space is typically one of the coldest, dampest, and most neglected areas of a home. Many homeowners are unaware of the energy loss, cold floors, and air quality issues that can stem from an underinsulated or improperly sealed crawl space. As a critical part of a home’s building envelope, crawl spaces are a major source of air leakage and discomfort.



Unfortunately, many crawl spaces either lack insulation altogether or have the wrong type—usually outdated fiberglass batts. This outdated method not only absorbs moisture, causing it to lose effectiveness and sag, but also promotes mold growth, wood rot, and pest infestations, which can threaten the home’s structural integrity.



At Premier Eco Builders, we specialize in modern crawl space insulation solutions that create a clean, dry, and energy-efficient environment beneath your home. By properly sealing and insulating your crawl space, we help eliminate cold floors, improve indoor air quality, and reduce heating and cooling costs. Contact us today for a free inspection and discover how we can transform your crawl space into a source of comfort and efficiency.
