Insulation Company in Rialto, CA
Blown in insulation is the workhorse solution for Rialto’s aging tract homes, where attics built in the 1950s through 1980s have original insulation that’s compacted to R-3 or worse. We’re Laguna Hills Insulation, and we’ve served Rialto since 2014 with blown-in fiberglass and cellulose, attic remediation, and spray foam across both 92376 and 92377. Most Rialto jobs are full attic re-levels with air sealing, not simple top-offs. Call (866) 393-6041 for a straight answer on what your attic actually needs.
Why Rialto Homes Are Different
Rialto’s housing stock was built fast and functional for Kaiser Steel and Santa Fe railroad workers, and those houses are still here by the thousands. Single-story ranch and stucco tract homes dominate 92376, with newer two-story subdivisions clustered in the northern 92377 foothills. The older homes share a pattern we see constantly: sparse, degraded fiberglass batts, minimal attic ventilation, and unsealed top plates that let Rialto’s desert heat pour straight into the living space. Because the inland valley swings from 100°F+ summer afternoons to near-freezing winter mornings, attics in these tracts show crushed batts near the eaves from repeated HVAC tech foot traffic. A proper job here means air sealing the top plates and re-leveling insulation before any new product goes down. Rialto sits east of the Cajon Pass, and the dry heat plus occasional Santa Ana winds also degrade cheap radiant barriers quickly. Homes here need insulation that performs in extreme heat, not just mild coastal conditions.
Our Main Rialto Services
Rialto homeowners call us most about two things: re-insulating attics in those aging tract homes, and sealing the building envelope with spray foam where air leakage is the real problem.
Attic Insulation in Rialto
Attic work in Rialto almost always starts with removal. The original insulation in 1950s-to-1980s tract homes has compacted over decades, and in many cases it’s down to R-3 or less, far below current Title 24 requirements. We remove the degraded material, air seal top plates and penetrations, verify or add ventilation, then install fresh insulation leveled edge to edge. Learn more about Attic Insulation in Rialto.
Spray Foam Insulation in Rialto
For Rialto homes where air leakage is driving the energy bills, spray foam creates an air barrier and thermal barrier in one application. Closed-cell foam from Icynene or Demilec performs well in Rialto’s 100°F+ summers, where attic temperatures push past 140°F and failing duct wrap costs homeowners real money. See Spray Foam Insulation in Rialto for the full breakdown.

Blown In Insulation in Rialto
Blown in insulation is the most practical, cost-effective answer for most Rialto attics, especially in the dense 92376 tract home inventory where original fiberglass has compacted to R-3 or less and must be fully removed and replaced rather than topped off. We blow in fiberglass or cellulose across the full attic floor after air sealing, leveling it to a consistent depth so R-value holds edge to edge, including over the top plates where Rialto’s heat loads in. Because we carry multiple brands including Owens Corning, Johns Manville, and GreenFiber, the material choice is driven by your attic’s condition and your budget, not by what’s on our truck. For a deeper look at the material options, see our full Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic has old, settled fiberglass, and you want a denser, recycled-content material that blocks air movement better than standard batts.
What it costs in Rialto
Blown-in cellulose for a typical Rialto attic runs $1.50 to $3.50 per square foot installed, depending on depth and whether we’re removing old material first.
How we do it
We remove and bag any degraded existing insulation, air seal top plates and penetrations, then blow GreenFiber cellulose to the depth required for the target R-value, leveling as we go.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic run 10 – 15°F hotter than the rest of the house in summer, or your energy bills climb every August in Rialto’s inland heat.
What it costs in Rialto
Full blown-in attic jobs in Rialto typically run $3,000 to $9,000 depending on attic size, access, and whether removal and air sealing are included.
How we do it
We inspect the attic, remove failed insulation if needed, seal bypasses, confirm or upgrade ventilation, then blow Owens Corning or Johns Manville fiberglass to a uniform depth across the entire attic floor.
Blown In Fiberglass Insulation
Signs you need it
You want an economical, non-combustible attic insulation that settles less than cellulose and is easy to top off later.
What it costs in Rialto
Blown-in fiberglass in Rialto ranges $1.00 to $2.50 per square foot installed at standard depths, before any removal or air sealing work.
How we do it
We prep the attic, seal air leaks at top plates and around chases, then blow fiberglass to the manufacturer’s specified depth for the R-value you’ve chosen, raking it level to eliminate thin spots.
Blown In Cellulose Insulation
Signs you need it
You’re comparing attic bids and want a denser, recycled-content insulation that delivers better air-blocking than fiberglass in Rialto’s hot, dry climate.
What it costs in Rialto
Blown-in cellulose for Rialto attics runs $1.50 to $3.50 per square foot installed, with removal and air sealing priced separately.
How we do it
We remove old material when required, air seal the attic floor, then blow GreenFiber cellulose to full depth and level it, paying extra attention to the eaves where Rialto’s tract homes lose the most heat.
Loose Fill Insulation
Signs you need it
Your attic has uneven coverage, bare spots at the eaves, or old material crushed down from decades of foot traffic from HVAC service calls.
What it costs in Rialto
Loose fill installation in a standard Rialto attic runs $1.50 to $2.50 per square foot, with existing-material removal adding to the final number.
How we do it
We evaluate existing depth and condition, remove or top off as the attic requires, and blow the loose fill material to a consistent, verified depth so the R-value is uniform across every square foot.

Is blown in insulation worth it in Rialto’s heat?
Yes, especially in 92376 tract homes where original attic insulation has settled to R-3 or less and the attic hits 140°F in summer. A full re-level to current R-value cuts cooling costs and evens out room temperatures. Call (866) 393-6041 for an exact price on your attic.
Can you blow insulation over old material in my Rialto attic?
Sometimes, but not often here. Most 1950s-1980s Rialto homes have material too compacted or dirty to top off, so removal is required first. We’ll inspect and tell you straight whether a top-off will work or full removal is needed. Call (866) 393-6041 for a free attic evaluation.
