Insulation Company in Sunnyslope, CA
Blown in insulation is the most common service we handle in Sunnyslope because so many homes here still run on original mid-century attic batts that have settled, compressed, or simply never matched the Inland Empire heat. The work is different than in coastal cities: we’re not chasing warmth, we’re stopping radiant heat gain and the fine quarry dust that rides the afternoon winds through every attic vent. Hollywood Insulation Co has served Sunnyslope since 2018, and the pattern is consistent on nearly every street: homeowners are paying for cooled air that leaks straight through the ceiling. Call (866) 605-6949 if your upstairs rooms run 10 degrees hotter than downstairs.
Why Sunnyslope Homes Are Different
Sunnyslope is an unincorporated Riverside County community tucked against the Jurupa Hills, and the construction stock tells a specific story. Most homes went up between the 1950s and 1980s as mid-century tracts and rural ranchettes. Builders insulated for a different climate and a different energy market. We routinely find original R-7 to R-11 batt insulation in attics that should carry R-38 or better under today’s standards. Walls in that era were often framed without any insulation cavity fill at all.
The climate punishes that deficiency. Summer highs push past 100°F for weeks at a time, and the sun loads directly onto roof decks facing the Jurupa Hills. Strong afternoon winds carry dust from the nearby aggregate quarries into attic spaces, where it settles into insulation and stains top plates dark at every vent opening. We see 1970s and 1980s blown-in attic insulation that has compressed to half its original depth simply from years of heat cycling. A home that once had R-19 may now perform at R-9. Newer infill custom homes in Sunnyslope tend to be better insulated, but even those benefit from air sealing and upgraded attic coverage. The zip code here is 92509, and the terrain ranges from flat tract lots to hillside builds where attic access is tighter and radiant exposure is stronger.
Our Main Sunnyslope Services
Sunnyslope homeowners call us most about two things: upgrading tired attic insulation and sealing the building envelope with spray foam. Both address the same underlying problem in this area, but they go about it differently.
Attic Insulation in Sunnyslope
Attic insulation is the first thing we check in Sunnyslope because heat gain through the ceiling drives most of the cooling bill here. Older homes on streets like 55th and 56th off Limonite often still carry their original thin batt layers. We inspect depth, condition, and air leakage, then build the attic back up to current code levels with the right material for the home. One local condition matters more than any other: the quarry dust that has been filtering into attics for decades means we often recommend removing or topdressing the existing layer rather than simply adding on top. Learn more about our Attic Insulation in Sunnyslope work.
Spray Foam Insulation in Sunnyslope
Spray foam solves what batt and blown-in insulation cannot: the air leaks. In Sunnyslope, the wind-driven dust intrusion at top plates, recessed lights, and plumbing penetrations means an air seal matters as much as the R-value. Closed-cell foam also adds structural rigidity, which helps on older hillside ranchettes that have shifted over the years. We install both Icynene and Demilec systems, open-cell and closed-cell, depending on the assembly and the budget. For a full breakdown of how foam performs in this climate, see Spray Foam Insulation in Sunnyslope.

Blown In Insulation in Sunnyslope
Blown in insulation in Sunnyslope is the fastest, most cost-effective way to restore an attic that has lost its thermal performance after decades of Riverside County heat. The homes here, mostly built between the 1950s and 1980s, often still have the original batt or settled loose-fill material that once worked but has since compressed under years of 100°F attic temperatures and dust infiltration from the Jurupa Hills quarries. We blow in new material over or in place of the old, bringing the attic up to current code levels and cutting cooling costs immediately. Hollywood Insulation Co has installed Blown In Insulation throughout Sunnyslope since 2018, and we carry both fiberglass and recycled cellulose options in this trade.
Cellulose Insulation
Signs you need it
Your attic insulation looks thin, gray, and dusty, and your ceiling feels warm to the touch on summer afternoons.
What it costs in Sunnyslope
Blown-in cellulose for a typical Sunnyslope attic runs $1.20 to $2.10 per square foot installed, depending on depth and access.
How we do it
We remove or topdress the old settled material, air-seal the major penetrations, and blow GreenFiber recycled cellulose to the specified depth for R-38 or better.
Blown In Attic Insulation
Signs you need it
Rooms at the back of the house stay hot all afternoon, and you can see exposed ceiling joists through thin, uneven attic insulation.
What it costs in Sunnyslope
Blown-in attic insulation in Sunnyslope typically ranges from $1,500 to $3,200 for a 1,000 to 1,500 square foot attic, including prep and air sealing.
How we do it
We run a hose up to the attic, blow loose-fill material to a uniform depth across every bay, and check for voids around recessed lights and duct chases before we finish.
Blown In Cellulose Insulation
Signs you need it
You want better insulation but prefer a recycled-content material, or your existing fiberglass has settled and compressed to a fraction of its original depth.
What it costs in Sunnyslope
Blown-in cellulose costs $1.20 to $2.10 per square foot installed in Sunnyslope, with most attics landing between $1,800 and $2,600 total.

How long does blown in insulation last in Sunnyslope?
Blown-in fiberglass and cellulose perform well for 20 to 30 years in Sunnyslope, but our summers accelerate settling, so we recommend a depth check every 5 years. Dust from the Jurupa Hills quarries can also reduce effectiveness. Call (866) 605-6949 for a free attic inspection.

If your project involves structural changes or spray foam in new construction, permitting is handled through the county. We’ll confirm on the estimate.
Yes. Air sealing the attic top plates, recessed lights, and plumbing penetrations significantly reduces the amount of quarry and construction dust that gets pulled into your living space. Combining air sealing with fresh blown-in insulation stops both the dust and the radiant heat. Call (866) 605-6949 for an inspection.

What Sunnyslope Customers Say
"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Miguel Garcia
