Whether you need crawl space encapsulation or attic insulation upgrades, our expert team delivers long-lasting solutions tailored to your needs.

Crawl Space Insulation & Encapsulation – A Comprehensive Approach

Crawl spaces play a crucial role in your home’s overall energy efficiency, yet they are often overlooked. Since 1997, we have been perfecting our approach to crawl space insulation using advanced spray foam techniques. Our process involves a multi-step strategy that effectively seals off air leaks, prevents moisture buildup, and creates a thermal break that significantly improves indoor air quality and energy efficiency.


We begin by spraying the sill boxes, foundation walls, and even the ground itself with high-quality spray foam insulation. This method ensures a complete thermal seal, preventing cold air from seeping in and stopping warm air from escaping. Unlike traditional insulation, spray foam captures and retains thermal energy, preventing it from being absorbed by concrete or lost through air leaks.


Another critical advantage of our crawl space insulation process is radon mitigation. Radon gas, a naturally occurring radioactive gas that can seep into homes from the ground, is a serious health hazard. Our spray foam application acts as a protective barrier, reducing the risk of radon infiltration and ensuring healthier indoor air quality for you and your family.


Additionally, in basement applications, we can install stud walls and spray foam insulation to further enhance thermal performance. We also use a specialized fire-resistant coating called DC-315, which turns into ash when exposed to high heat. Once it becomes ash, there is no remaining fuel source, enhancing fire safety within your home.

Attic Insulation – A Layered Approach for Maximum Efficiency

Proper attic insulation is crucial for maintaining a consistent indoor temperature and reducing energy costs. New construction attics require specialized insulation strategies to ensure proper airflow and thermal efficiency. Our team follows a step-by-step process designed to create an air seal, regulate attic ventilation, and maximize insulation effectiveness.


First, we remove all old insulation, which may be inefficient or contaminated with dust, allergens, and pests. Once the attic is cleared, we apply 1.5 to 2 inches of spray foam insulation along the attic deck. This layer creates an airtight thermal break, sealing off air leaks and preventing heat loss.


Proper attic ventilation is essential, especially for new construction homes. Air needs to flow from the soffit vents up through the attic to prevent moisture buildup and condensation issues. By sealing off air leaks and maintaining proper ventilation pathways, we ensure your attic can breathe while still retaining maximum insulation efficiency.


After the spray foam application, we blow in 14 inches of fiberglass insulation over the foam layer. This combination of spray foam and fiberglass creates an extremely effective insulation system, maximizing both air sealing and thermal retention.


Lastly, we address the scuttle hole, the access point to your attic. Since this opening is often a major source of heat loss, we construct an inverted cooler-style cover to provide additional insulation and maintain the attic’s thermal integrity. This ensures that conditioned air stays inside your home rather than escaping through the attic hatch.
