How does Coronado's climate affect this service?
Coronado takes the strongest salt exposure in the county, the island microclimate runs cooler and damper year-round with marine humidity that migrates through every unsealed chase. Historic Victorian and Craftsman stock in the Village is 70-plus years old with original or no insulation, and Navy family rentals plus historic-preservation expectations shape almost every project.. Coastal blown-in is mostly attic top-ups in Coronado and Imperial Beach housing stock from 1970–1995.
Cellulose or fiberglass, which is better?
Cellulose has higher R per inch, better air-flow resistance, and is recycled paper treated for fire and pests. Fiberglass is non-organic, lighter, and easier in damp climates. In dry, mild San Diego the pro uses cellulose more often unless the attic has past moisture issues.
What is dense-pack?
Dense-pack is cellulose installed at 3.5 lb/cu ft into closed wall cavities through small drilled holes. The high density resists settling, plugs air leaks, and adds R-13 to R-15 to a wall that previously had nothing. The pro patches and texture before paint.
