NGI LLC

NGI Solutions operates as a licensed insulation contractor serving Norcross and the greater Gwinnett County area, including Lawrenceville and surrounding communities. The business holds a perfect 5-star rating built across 8 verified customer reviews, reflecting steady craftsmanship on both residential and light commercial projects. Their service menu spans spray foam applications, crawl space encapsulation, attic insulation upgrades, and traditional fiberglass systems. Operating hours run Monday through Saturday from 7 AM to 5 PM, allowing flexible scheduling for property owners managing occupied homes.

The team specializes in spray foam technology, delivering open-cell and closed-cell formulations that achieve superior R-value performance per inch compared to conventional batts or blown-in materials. Crawl space encapsulation ranks as a signature service, transforming damp, smelling foundations into sealed, conditioned zones that block moisture and improve indoor air quality throughout the entire home. Each project begins with a detailed assessment so homeowners understand material choices, thermal performance expectations, and realistic energy savings before any product is applied.

Customer reviews consistently highlight Daniel and his crew for methodical preparation and immaculate worksite protocols. Bryan Moran's 40x60 workshop received full spray foam treatment, the team protected all surrounding surfaces before application, and the space now maintains comfortable temperatures year-round without air conditioning. Alma A's Lawrenceville residence had attic and crawlspace insulation replaced, resolving persistent allergy problems from old fiberglass and delivering immediately noticeable temperature improvements and lower utility bills.
