Newer home.
Higher bills. You're not imagining it.
Orange County's tract homes look great from the street. Inside the attic is a different story — minimum-code insulation from 1998, settling and degrading for 25 years. Add canyon-edge wildlife and you've got two expensive problems most homeowners don't see coming.
The "newer house" assumption that's costing you every month.
There's a belief that runs through a lot of Orange County neighborhoods — Irvine, Mission Viejo, Yorba Linda, Rancho Santa Margarita — that goes something like: my house was built in the '90s or 2000s, so the insulation is probably fine.
It's usually not.
California's Title 24 energy code requirements in 1992 were a fraction of what they are today. Tract builders in the '90s and early 2000s installed the legal minimum — which meant thin batt insulation packed loosely into an attic that was never air-sealed. Twenty-five years later, that insulation has compressed, shifted, and in many cases absorbed moisture from a roof that may have had minor leaks over the years. It's not doing much anymore.
What you feel is that your home never quite reaches the temperature on the thermostat. The upstairs bedrooms are always warmer. The AC runs longer than it should. Inland OC summers — Anaheim Hills in July, the hills above Fullerton — get brutal, and a compromised attic makes it worse than it needs to be.
The fix is straightforward but it has to be done right. We remove what's there, air-seal the attic floor, and install blown-in insulation to current R-38 to R-60 standards. Air sealing first — always. An attic full of new insulation with gaps in the ceiling plane is still an attic losing conditioned air. We don't skip that step.
- Complete insulation removal and disposal
- Attic floor air sealing before new installation
- Blown-in fiberglass and cellulose (R-38 to R-60)
- Crawlspace encapsulation and under-floor insulation
- California Title 24 compliant on every job
- Written documentation of R-value before and after
If your backyard faces a canyon, something has already checked your roofline.
A significant portion of Orange County's residential areas sit at the edge of open space — the hillsides above Laguna Niguel, the canyons behind Coto de Caza, the scrub behind Anaheim Hills and Yorba Linda. It's one of the things that makes living here feel different from the rest of Southern California. It's also why roof rats are a constant problem in those neighborhoods.
Rats don't need an invitation. They move along fence lines, up trees, across utility wires, and onto your roof. OC's Mediterranean-style architecture — the tile roofs, the wide eaves, the stucco soffits — gives them more potential entry points than almost any other housing style in the state. The gap where a clay tile sits slightly uneven. A cracked soffit panel. A vent screen that's been there since 1994 and has a corner lifted. We've inspected homes in Lake Forest and Aliso Viejo where rats had been living undisturbed for what was clearly more than one season.
The damage compounds quietly. Insulation gets shredded and matted down. Wiring gets chewed. The smell works its way into the living space slowly enough that most homeowners assume it's something else. By the time someone calls us, the cleanup is significant.
What we do is not glamorous, but it's thorough. We walk the entire perimeter — roofline, soffits, foundation, utility penetrations — and we seal everything with material rats cannot get through. Galvanized steel mesh. Hardware cloth on every vent. Professional sealant on every gap. Then we remove what they left behind and decontaminate properly. Not a spray-and-go job.
- Full perimeter inspection — roofline, tile gaps, soffits, foundation
- Galvanized steel mesh on all vents and openings
- Tile roof gap assessment and sealing
- Soffit panel repair and hardware cloth installation
- Contaminated insulation removal with Hantavirus protocols
- Attic decontamination and sanitization
- Full insulation replacement after cleanup
We give you the full picture. Then you decide.
A lot of contractors in Orange County will walk through a job quickly and hand you a number. We do something different — we document everything, explain what we found, and tell you honestly what needs to happen now and what can wait. No high-pressure close. No inflated scope.
Full Documentation
Before we do anything, we photograph and log every issue we find. You get a clear picture of what's actually in your attic — not a verbal summary.

Insulation + Exclusion, Together
Most companies do one or the other. We do both — which matters when rats already destroyed the insulation. One crew, one visit, one warranty.
