How does Chula Vista's climate affect this service?
Chula Vista is San Diego County's second-largest city, split sharply between older west-side stock (55-plus years old, original underperforming insulation) and newer east-side master-plan developments (Otay Ranch, EastLake, Rancho del Rey from 1995-2015). Different scope on each side, full upgrade west, ductwork and air-sealing tightening east.. South County blown-in serves both attic top-ups in older National City and Chula Vista homes and dense-pack walls in pre-1980 stock.
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.
