Insulation Company in Northridge, CA
Northridge homes need insulation that can handle triple-digit Valley summers and cool winter nights without letting your AC work itself to death. Most attics we see in Northridge were built in the 1950s and 60s with thin fiberglass batts that have settled into near-uselessness, and many post-1994-quake rebuilds cut corners on insulation to save money. We’re Laurel Attic Insulation, part of the Relay Home Co. family since 2003. Chase Whitaker leads our team, and every job starts with a written price before work begins.

Why Northridge Homes Are Different
The 1994 earthquake left a mark on Northridge you can still feel in your attic. Homes rebuilt after the quake were often put up fast, with minimal insulation to keep costs down. Twenty-plus years later, owners are paying for that shortcut every July when the AC runs nonstop and the upstairs still won’t cool below 80. We see this pattern constantly in the neighborhoods around CSUN and along Reseda Boulevard. Meanwhile, the original 1950s and 60s ranch homes that dominate Northridge still have their first-generation fiberglass batts, now compressed, dusty, and doing almost nothing. Add in the earthquake retrofit straps bolted into many Northridge attic frames, and you have a job that genuinely requires a local crew who knows what they’re looking at.
The climate punishes bad insulation fast here. Summer days over 100°F turn an under-insulated attic into an oven that radiates heat down through your ceiling all night. Winter brings the opposite problem: cool nights and warm days create condensation when insulation is installed poorly or has gaps. Northridge homeowners also deal with a mix of 1970s and 80s townhomes whose exterior walls were built with no insulation at all. Those walls leak conditioned air year-round, and fixing them is a different job than topping up attic batts.
Our Main Northridge Services
The two calls we get most from Northridge are for attic insulation that’s finally given up and spray foam for walls and crawl spaces that were never insulated to begin with. Insulation removal rounds out the roster, usually as the first step before a retrofit.
Attic Insulation in Northridge
Most Northridge attic jobs start with us measuring what’s already up there, which is often R-19 fiberglass batts from the Eisenhower administration that have compressed to half their original thickness. We replace it with blown-in or batt insulation matched to your home’s R-value needs, and we navigate around the earthquake retrofit straps that Crisscross many Northridge attic frames. Those straps make the job trickier than a standard attic, but it’s nothing a crew that works in Northridge every week hasn’t handled. Full details on Attic Insulation in Northridge.
Spray Foam Insulation in Northridge
For uninsulated exterior walls in Northridge townhomes and for sealing rim joists in ranch homes, spray foam does what batts can’t: it fills the entire cavity and seals air leaks at the same time. That matters when summer attic temps hit 140°F and your AC is fighting heat coming from every direction. We use open-cell and closed-cell foam depending on the job, and we’ll give you a straight answer about which one fits your walls and budget. Full details on Spray Foam Insulation in Northridge.
Insulation Removal in Northridge
If your attic has old, rodent-soiled, or water-damaged insulation, the first move is getting it out completely. We vacuum out the old material, clean the attic deck, and prep it for fresh insulation. In Northridge, we often pull out quake-damaged insulation that got soaked or contaminated when roof damage went unrepaired years ago. You don’t want to layer new insulation over material that’s holding moisture or pests. Full details on Insulation Removal in Northridge.
