Insulation Before & After in Long Beach, CA
We can describe R-values, air sealing, and thermal boundaries all day, but nothing lands like seeing the difference. In Long Beach homes, the gap between an under-insulated attic and a properly insulated one shows up on energy bills, in rooms that never quite cool down, and in that stubborn second-floor heat in August. Here are a few transformations our crew has handled across Long Beach, from Naples to Bixby Knolls. Each one started with a specific complaint and ended with a measurable fix.
Recent Transformations
Blown-In Fiberglass: 1950s Lakewood Village Attic
The problem: this Lakewood Village home still had its original 1950s batt insulation, compressed and settled to maybe R-11 in spots. The homeowner said the hallway stayed warm at midnight in July, no matter what the thermostat read. We removed the old material and blew in fresh fiberglass to a consistent depth across the whole attic plane. The result was a full R-38 ceiling with no gaps around the eaves where heat had been pouring in.
Insulation Removal After Roof Leak: Belmont Heights
The problem: a slow roof leak above a Belmont Heights bungalow had soaked the cellulose insulation into a matted, musty mess. You could smell it from the hallway. We extracted everything down to the deck, sanitized the space, and let it dry properly before any new material went in. Then we blew in fresh GreenFiber cellulose at full depth. The homeowner said the stale smell was gone within a week, and the upstairs landing finally held a steady temperature.
Attic Air Sealing and Blown-In: Bixby Knolls Two-Story
The problem: a Bixby Knolls homeowner was running the AC constantly while the upstairs bedrooms still hit 80 degrees in the afternoon. The attic inspection showed exactly what we expected: recessed lights, plumbing vents, and top plates all unsealed, with maybe six inches of settled insulation. We air-sealed every penetration we could reach, then blew Owens Corning fiberglass over the top to R-38. The upstairs rooms now cool within a half hour of the AC kicking on.
R-Value Upgrade: Los Altos Mid-Century
The problem: a Los Altos mid-century had the original loose-fill insulation from the 1960s, and it had compacted down to a thin, dusty layer. The homeowner could see daylight through gaps around the chimney chase. We topped everything off with Johns Manville blown-in fiberglass to bring the attic to a uniform R-38. The difference was immediate: the living room no longer felt drafty in winter, and the AC bills dropped noticeably that first summer.
Utility Room Sound and Heat: Bluff Park Condo
The problem: a Bluff Park condo had a utility closet sharing a wall with the bedroom, and the water heater made it feel like sleeping next to an engine. The wall cavity was completely empty. We cut the drywall, fitted Rockwool batts into the stud bays, and buttoned it back up. The homeowner told us the mechanical noise dropped to a low hum, and the bedroom no longer picked up heat from the closet.
Rodent-Damaged Attic Cleanup: North Long Beach
The problem: a North Long Beach rental had been vacant for a few months, and something had made a home in the attic. The insulation was torn, compressed, and scattered with droppings. We removed every trace of the old material, vacuumed the space, and blew in fresh CertainTeed fiberglass. The property manager said the unit rented within two weeks of the cleanup, and the new tenant has not reported a single issue.
