Blown-in insulation is the workhorse of attic upgrades. We feed loose-fill fiberglass or cellulose through a hose from the truck to the attic and spread it in an even layer that fills around wires, pipes and odd framing. That leaves none of the gaps and seams that let heat through. For most Los Angeles homes with a walkable attic, it is the fastest and most cost-effective way to reach R-38 or R-49.
Fiberglass or cellulose
Loose-fill fiberglass is light, non-combustible and does not absorb moisture. Cellulose is made from recycled paper treated for fire resistance, and it is denser, which helps slow air movement. Both perform well when installed at the right depth. We will recommend one based on your attic, your ventilation and anyone in the home with sensitivities.
Depth you can check
We blow to a measured depth for your target R-value and leave depth rulers in the attic so you can see it for yourself. You get an attic card at the hatch listing the material, R-value and depth, plus before-and-after photos sent to your phone.
Over old insulation, or after removal
If your existing insulation is dry, clean and free of rodent waste, we can blow new material right on top of it. That is the most affordable route. If it is contaminated or water-damaged, we will show you photos and recommend a removal first.
Signs you could use this
- Your attic insulation is less than 6 inches deep
- Insulation is patchy, with bare drywall showing in places
- Cable, solar or HVAC work has trampled the attic floor
- You are re-roofing or replacing your AC and want the full benefit
- Summer electric bills keep climbing
