Attic Insulation
Attic Insulation built for Southern California homes
In Southern California, attic temperatures can climb well past 140°F on summer afternoons. Without enough insulation, that heat radiates straight into your living space and forces your AC to work overtime.
We remove old, compressed, or contaminated insulation, seal the air leaks that let conditioned air escape, and install new insulation to recommended R‑values. It's one of the fastest-payback upgrades you can make, and it means you may need a smaller solar system.
- Attic inspection with photos
- Recommended R‑values for California Title 24
- Rodent-proofing and sanitizing
- Same-day installation for most homes

FAQ
Attic Insulation questions
How do I know if my attic needs more insulation?
If your insulation is below the top of the ceiling joists, looks flattened or patchy, or upstairs rooms run hot, you likely need more. We'll inspect your attic and show you photos.
How long does attic insulation take?
Most homes are completed in a single day, including removal of old insulation when needed.
Should I insulate before going solar?
Often, yes. Reducing your home's energy use first can lower the size and cost of the solar system you need.
