Explore installationEvery active and potential entry point backed with 1/8-inch galvanized steel mesh or steel wool, sealed with silicone, foam, or stucco patch over the steel — screwed, verified, and photographed before and after.
Explore rodent proofingContaminated material out under containment with 35-HP vacuum extraction into sealed bags — a clean, documented baseline.
ExploreEPA-registered disinfectants under a CDC-informed protocol — neutralizing what rodents leave behind, at the source.
ExploreClose the ceiling-plane leaks insulation can't fix, and repair the ducts that decide where your conditioned air actually goes.
ExploreCleanup, steel exclusion, and ground-moisture control beneath the home — because the stack effect pulls crawl space air up into your living space every day.

Summer heat radiating through thin insulation. Conditioned air escaping through unsealed penetrations. Rodents following canyon edges to unprotected vents. Ground moisture rising into the air your family breathes. None of it announces itself — it shows up as a utility bill, a warm bedroom, a scratching sound at 2 a.m.
Maintained properly, the same two spaces work for you: stable temperatures, lower bills, cleaner air, and a documented history that pays off the day you sell.
The same disciplined sequence on every project — in the professional order, never skipped.
About an hour in your attic or crawl space with a camera and a ruler. You get a written three-column scope — including when the honest answer is "your attic is fine." No pressure, no expiring quote.
Remove and clean under containment, seal entry points in steel, sanitize, air seal, then restore insulation to full depth. Most projects finish in one to two days, on a timeline we put in writing.
Before, during, and after photos of every major step, completion paperwork, and a documented baseline — with the same local number answering in year one, year two, and year three.
Every ruler standing in fresh insulation, every steel-sealed entry point, every before-and-after — photographed and handed to you. Because the two spaces you never look at shouldn't be the two spaces you have to take on faith.
Fiberglass insulation from Owens Corning, CertainTeed, and Johns Manville — manufacturer warranties typically 10–25 years, behind our own workmanship guarantee.
Every installation designed to meet or exceed Title 24 for your climate zone — and savings expectations follow the published ENERGY STAR methodology, around 15%, never inflated.
C-2 Insulation and B General, bonded and insured — verify us at the CSLB in thirty seconds, and run the same check on anyone else who quotes your attic. The C-2 is legally required for this work.
Rodents chew straight through foam on its own — so every sealed point starts with 1/8-inch steel mesh or steel wool, with foam, silicone, or stucco patch finishing over the steel. The steel is never optional.
Every major step documented before, during, and after — so you never take our word for what happened above your ceiling or under your floor.
Plenty of inspections end with a documented healthy attic, delivered free — because manufactured urgency isn't a service.
No same-day-only pricing, no pressure — quotes stay valid while you think, compare, and decide. That's how trust survives.
From our Escondido headquarters across San Diego, Southwest Riverside, and South Orange Counties — every city with its own local page covering its housing eras, climate, and the attic problems we actually find there.
