Insulation Company in Rialto, CA
Blown in insulation solves the single biggest comfort problem in Rialto: attics that hit 140°F-plus on summer afternoons and bake the living space below. Most homes here were built between the 1950s and 1980s, and their original attic batts are compressed, sagging, or disintegrated. North Tustin Insulation has served Rialto since 2011, and we match the material to your home, not the other way around. Call (877) 265-5712 for a free estimate.
Why Rialto Homes Are Different
Rialto’s housing stock tells a specific story. The older core around 92376 is mostly 1950s through 1970s single-story ranch and stucco homes, many with original R-11 attic batts or thin loose fill that was marginal when installed and has only degraded since. The 92377 neighborhoods to the north skew 1980s and 1990s, but plenty of those homes have uninsulated garages, additions with no thermal barrier, and minimal wall cavities that predate modern Title 24 requirements. It means we aren’t usually selling an upgrade from decent to premium. We’re replacing cooked-out original insulation and fixing radiant heat gain that makes a 1970s Rialto tract house brutally hot by 2 p.m.
The climate works against old insulation in a specific way. Rialto sits east of the Cajon Pass in the dry Inland Empire heat. Summer highs routinely cross 100°F, and attic temperatures push well past 140°F. Any fiberglass batt that has baked up there for 30 or 40 years has lost its loft. We routinely find original batts collapsed off the joists or matted into a dense layer that has to be vacuumed out before new material goes in. Winter nights are mild, but a proper attic R-value still keeps the furnace from cycling too often. The job here is not a generic re-insulate; it’s a rebuild of the thermal boundary based on what the home actually has.
Our Main Rialto Services
Rialto homeowners call us most often about two things: bringing an under-insulated attic up to a level that actually fights the Inland Empire heat, and sealing hard-to-reach spaces with spray foam where batts can’t do the job.
Attic Insulation in Rialto
Most Rialto attics we open have original fiberglass batts that measured R-11 or R-19 new and now perform far below that. In a 1960s ranch with a dark composition roof, that translates directly to a second story or ceiling that never cools down. We remove the old material when it’s collapsed or contaminated, air-seal the attic floor, and blow in fresh insulation at the R-value the home needs. Attic Insulation in Rialto covers the process, materials, and what it costs.
Spray Foam Insulation in Rialto
Rialto has a lot of additions and garage conversions with no insulation at all, plus older homes with awkward cavities where batts never fit right. Spray foam handles those spaces and creates an air seal that blown-in material alone cannot. It’s also the better choice for attics with HVAC equipment or ductwork running through them. Spray Foam Insulation in Rialto breaks down open-cell versus closed-cell and when each makes sense here.

Blown In Insulation in Rialto
Blown in insulation is the workhorse for Rialto attics. A 1960s home with collapsed original batts needs that failed material removed and a loose-fill layer blown in at a consistent depth, which restores the R-value the attic was supposed to have. Our technicians handle removal, air-sealing, and installation with an insulation-exclusive crew that does this every day. Our full Blown In Insulation service page covers the methods and options in detail.
Cellulose Insulation

How we do it
We remove failed material if needed, air-seal penetrations, and blow GreenFiber cellulose to the specified depth with consistent coverage.

Blown In Cellulose Insulation
Signs you need it
You want a recycled-content material that packs well into irregular attic cavities and resists airflow better than fiberglass.

How we do it
We use GreenFiber recycled cellulose and calibrate the blowing machine to the correct density for even coverage and the target depth.

What it costs in Rialto
Loose fill insulation in Rialto ranges $800 – $4,500 depending on attic size, access difficulty, and whether old material must be removed first.
How we do it
We inspect the attic, remove or top up existing material as needed, and blow loose fill to a uniform depth verified with depth markers.
What Blown In Insulation Costs in Rialto
| Item | Typical range in Rialto |
| Blown-in attic insulation (full job) | $2,500 – $4,500 |
| Blown-in cellulose (materials and labor) | $1.00 – $1.50 per square foot |
| Full attic removal and re-blow | $800 – $4,500 depending on size |
How long does blown in insulation last in Rialto?
Blown-in insulation lasts 20 – 30 years if the attic stays dry. Rialto’s heat accelerates settling in fiberglass, so a depth check every decade is worth doing to make sure the R-value hasn’t dropped.
Can you blow insulation over old batts in Rialto?
Only if the old batts are intact and dry. In most 1950s – 1970s Rialto homes, the original material is compressed or contaminated, so we remove it first. Call (877) 265-5712 for an honest assessment.

We carry and install Owens Corning, GreenFiber, Demilec, and Johns Manville products, among others, so your Rialto home gets the right material rather than whatever is in stock. Our our brands page shows the full lineup. Most materials are ready for Rialto jobs within a standard scheduling window.
