Insulation Company in Berkeley, CA
Berkeley homes need insulation that handles damp marine air, steep hillside lots, and housing stock that runs from 1910 Craftsman bungalows to 1960s flat-roof mid-centuries. We’re Laurel Attic Insulation, the insulation specialist in the Relay Home Co. family, and we work across every Berkeley neighborhood with written pricing before work starts and live arrival tracking on every job.

Why Berkeley Homes Are Different
Berkeley’s fog and winter rain mean attic insulation here fights moisture as much as heat loss. Fiberglass batts that work fine in dry inland climates can sag and lose R-value when Bay moisture creeps into poorly vented attics. R-value is the number that measures how well insulation slows heat from moving through your ceiling, and in Berkeley we routinely find older homes in the Elmwood and Claremont districts running at half the R-value the California Energy Code expects for this climate zone.
Housing age changes the job, too. Pre-war homes in North Berkeley and the flats often have knob-and-tube wiring in attic cavities that must be addressed before new insulation goes in. Hillside homes near Grizzly Peak and the Berkeley Hills face wind-driven rain that makes air sealing just as important as the insulation itself. And many Berkeley neighborhoods have strict design review rules: if your home sits in a historic district, any visible exterior vent changes need a permit before work starts. We’ve done enough Berkeley attics to know which homes will trigger that conversation and which won’t.
Our Main Berkeley Services
Berkeley homeowners most often call us for two kinds of work: bringing aging attic insulation up to code, and removing old or contaminated material that’s doing more harm than good. Here’s how each one works in Berkeley.
Attic Insulation in Berkeley
Most Berkeley attics we see are under-insulated by modern standards, especially in homes built before Title 24 energy codes took attic R-values seriously. We typically blow in fiberglass or cellulose to bring attics up to R-38 or R-49, which makes a measurable difference in how stable upstairs rooms feel during Berkeley’s cool summer fog and cold winter nights. Every job starts with a written price, and we use materials from brands like Owens Corning, GreenFiber, and Knauf, matched to your attic’s existing setup. Attic Insulation in Berkeley
Spray Foam Insulation in Berkeley
Spray foam earns its keep in Berkeley homes with unvented attics, knee walls, or hillside crawlspaces where air leakage is the real comfort problem. Closed-cell foam also adds structural rigidity, which matters on steep Berkeley Hills lots where wind load is a factor. We use professional two-part foam systems from brands like Icynene and Demilec, installed by background-checked technicians with a written price before anything starts.

Insulation Removal in Berkeley
Older Berkeley homes sometimes hide insulation that’s gone bad: rodent-soiled fiberglass, settled cellulose that’s lost its loft, or vermiculite that needs professional handling. We remove the old material completely, clean the attic floor, and leave the space ready for new insulation. Removal in Berkeley often means working in tight attic access points on houses built before modern building codes, and we’re set up for that kind of work. Insulation Removal in Berkeley
