If the existing material is clean, dry, and even, topping it off after air sealing may be enough. If it's contaminated by rodents, wet, compacted, or producing odors, new insulation on top only traps the problem underneath — removal creates the clean baseline that makes everything after it work. The free inspection settles which situation you have, with photos.

Fiberglass is the Attic Shield most-recommended attic default: it holds its rated R-value for the life of the attic, shrugs off a one-time roof leak, and moves aside and back for future repairs without falling apart. It is not the only tool on the truck — we also install cellulose and mineral wool where the assembly calls for them, and our cellulose vs. fiberglass guide lays that decision out honestly. Spray foam is the one we advise against in residential attics — it bonds to the roof deck, hides leaks and rodent activity instead of revealing them, and turns every future inspection into a demolition job. Whatever the material, it goes in over a properly air-sealed ceiling plane at a measured, photographed depth — the combination behind the ENERGY STAR guidance of roughly 15% savings on heating and cooling.

Yes, and most homes need exactly that. The attic and the crawl space are two halves of the same pressure system: air leaks in at the bottom of the house and out at the top, dragging crawl space air — and everything in it — up through your living space on the way. Sealing one end while ignoring the other leaves half the problem in place. On a combined project the crew inspects both spaces in the same visit, photographs both, and writes one scope that covers exclusion, cleanup, vapor barrier, air sealing, and insulation as a single sequence. One crew, one timeline, one set of before-and-after photographs — and a house that finally behaves like the sealed envelope it was designed to be.

The crew runs out of Escondido and covers more than seventy cities across three counties. In San Diego County that includes San Diego itself, Carlsbad, Oceanside, Chula Vista, La Jolla, Poway, El Cajon, Encinitas, Vista, and San Marcos. Across Southwest Riverside we work Temecula, Murrieta, Menifee, and Lake Elsinore, and in South Orange County we reach San Clemente, Mission Viejo, and Laguna Niguel. Coastal homes bring salt air and moisture questions, inland homes bring heat load and rodent pressure — the inspection is the same either way: about an hour in the attic and the crawl space, photographs of what we find, and a written scope before anything is scheduled. If your city isn't listed here, call anyway; the service map keeps growing.
