Insulation Company in Sunnyslope, CA
Blown in insulation is the workhorse retrofit for Sunnyslope’s aging ranch and tract homes, most of which were built decades before Title 24 energy standards existed. We install loose fill fiberglass and cellulose in attics across 92509, correcting decades of settled, compressed, or simply missing coverage that lets triple digit summer heat pour through ceilings. If your cooling bill climbs every August while the house stays warm, call us at (866) 393-6041 for a free attic assessment.
Why Sunnyslope Homes Are Different
Sunnyslope sits in the Jurupa Valley stretch of Riverside County where summer heat routinely passes 100°F, and the older unincorporated housing stock was largely built without today’s Title 24 insulation requirements. That means attic and wall insulation here is as much about surviving August heat gain as saving energy. Homes built in the 1950s and 1960s often have R-11 fiberglass batts at best, and many have nothing left but dust and rat droppings after sixty years of settling. Attics in this part of the valley routinely bake above 140°F in summer. When HVAC ducts run through that oven, the system works twice as hard as it should, and the homeowner sees it on the bill months before they think to look up. This is not coastal work. There is no marine layer to soften the afternoon sun, and winter nights drop low enough that heat loss through a thin attic becomes a real comfort problem too. The insulation spec that works in Huntington Beach fails here by August.
Our Main Sunnyslope Services
Most Sunnyslope homeowners call us about two jobs: re-insulating an under-insulated attic, or sealing and insulating an attic with spray foam where the existing setup has failed. Both are covered below.
Attic Insulation in Sunnyslope
Older Sunnyslope attics usually need the existing material removed or topped off, then a fresh layer of blown in insulation brought up to a spec that makes sense for Riverside County heat. We check duct condition and air sealing at the same time, because a well insulated attic with leaky ducts still wastes energy. For a full breakdown of this service, see Attic Insulation in Sunnyslope.

Spray Foam Insulation in Sunnyslope
Some Sunnyslope homes, particularly those with ductwork in the attic or cathedral ceilings, benefit more from closed cell spray foam than from loose fill. Foam creates an air barrier and a thermal barrier in one application, which matters when the attic is part of the conditioned space or when air leakage is the bigger problem. We install Icynene and Demilec products for these jobs. Learn more at Spray Foam Insulation in Sunnyslope.

Blown In Insulation in Sunnyslope
Blown in insulation is the most cost effective retrofit for the majority of Sunnyslope homes, especially the mid century ranch and tract houses where the original attic insulation has settled to nothing. We install loose fill fiberglass and cellulose from Blown In Insulation across 92509, bringing attics up to a level that actually handles 140°F attic temperatures in July and August. The payoff is immediate: lower ceiling temperatures, a cooling system that cycles off now and then, and a house that holds warmth on cold winter nights.
Cellulose Insulation
Signs you need it
Your existing attic insulation is settled, dusty, or full of gaps, and you want a dense, recycled material that fills odd cavities better than fiberglass can.
What it costs in Sunnyslope
Cellulose blown in insulation in Sunnyslope typically runs $2.10 to $3.80 per square foot installed, depending on depth and attic access.
How we do it
We dense pack or loose fill GreenFiber cellulose to the target R-value, using a blower truck and hoses that let us reach every corner of a Sunnyslope attic without disturbing the living space.
Blown In Attic Insulation
Signs you need it
You can see the ceiling joists in your attic because the existing insulation is so thin, or your upstairs rooms run ten degrees hotter than the rest of the house in summer.
What it costs in Sunnyslope
Blown in attic insulation for a typical Sunnyslope ranch home falls between $1,800 and $4,200 depending on square footage and final R-value.
How we do it
We air seal the attic floor penetrations first, then blow Owens Corning or Johns Manville loose fill fiberglass to a consistent depth across the entire attic, including the hard to reach edges over the exterior walls.

| Item | Typical range in Sunnyslope |
|---|---|
| Blown in fiberglass attic insulation | $1,600 – $3,900 |
| Blown in cellulose insulation | $2.10 – $3.80 per sq ft |

Is blown in insulation worth it for older Sunnyslope homes?
Yes. Older Sunnyslope attics lose most of their original insulation within a few decades, and replacing it with blown in material is the fastest, least invasive way to cut cooling costs. Call (866) 393-6041 for a free attic inspection.
How long does blown in insulation last in a Sunnyslope attic?
Fiberglass and cellulose last 20 to 30 years if kept dry, but Sunnyslope attics get hot enough to degrade batts faster. Blown in material settles over time and may need a top off after a decade. Call (866) 393-6041 for an assessment.
