Attic Insulation in Norwalk
Licensed, insured contractors providing expert attic insulation to homeowners across Norwalk and the Gateway Cities region.
Most Norwalk homes are under-insulated in the attic, leading to high cooling costs and uncomfortable summer temperatures indoors. Eco Grizzly installs blown-in fiberglass, blown-in cellulose, and batt insulation throughout Norwalk, La Mirada, Santa Fe Springs, Cerritos, Downey, Bellflower, Whittier to bring attics up to the R-38 to R-60 levels recommended for this climate zone. We also air-seal penetrations before adding insulation to maximize energy savings. Norwalk's residential neighborhoods were developed in the 1950s and 1960s. Most homes have original brick chimneys and standard fireplaces that benefit from professional maintenance after decades of service.

BeforeAttic Insulation Removal and Installation
Southern California
The existing attic insulation had settled and degraded over time, leaving large areas with minimal thermal protection. Our crew removed all old insulation down to the ceiling joists, cleaned the attic space, sealed air leaks around penetrations, and installed new blown-in insulation to current energy code requirements. The homeowner saw an immediate improvement in indoor comfort and lower utility bills.
