    A Bit About Us

    For over 40 years, Joel Smallwood has been dedicated to delivering insulation excellence.

    Our story began in 1980 when Joel started in the industry, learning the business from installation to estimating at the respected Gearhart Insulation. This hands-on experience became the foundation of our uncompromising commitment to quality.

    After purchasing Gearhart Insulation to preserve its legacy, Joel launched NCI in 2008. Today, NCI is the culmination of four decades of continuous expertise and dedication.

    We don’t just insulate buildings; we apply generational knowledge to ensure the highest quality products and applications, guaranteeing the comfort and energy efficiency that protects your family’s investment for the future.
