How does Harbison Canyon's climate affect this service?
Harbison Canyon took heavy damage in the 2003 Cedar Fire and remains in the burn zone, ember-resistant ventilation required, Class A assembly documentation expected by insurance carriers, and freeze-protection scope routine on winter mornings. Many homes here are post-fire rebuilds with newer assemblies, but original-stock attics are settled and underperforming.. Backcountry blown-in often goes deeper than code minimum because winter heat loss is a bigger concern than summer cooling.
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.
