Insulation Company in Redlands, CA
Blown in insulation solves a problem we see constantly in Redlands: attics with old, compressed fiberglass that stopped doing its job years ago. Homes here run the gamut from 1950s tract houses to 1920s bungalows, and most of them were built for a climate nobody thought much about when energy was cheap. Redlands summers push attic temperatures past 140°F, and that heat pushes down into living spaces all afternoon. We’re Fontana Insulation, and our crew has worked in Redlands zip codes 92373, 92374, and 92375 since 2011. Call (866) 271-1602 for a free estimate on blown in insulation or any other insulation job.
Why Redlands Homes Are Different
Redlands sits in the inland Inland Empire, where summers are long, dry, and genuinely punishing for any home that isn’t sealed tight. The heat load is the story here, not winter cold. We measure attic temperatures above 140°F routinely from June through September, and that radiant heat drives cooling bills through the roof in more ways than one. What makes Redlands tricky is the housing stock itself. The historic neighborhoods near downtown, particularly around Olive Avenue and Cajon Street, have knob-and-tube-era construction with little to no wall insulation. Those homes need a different approach than the mid-century tract homes spread across south Redlands, many of which have original attic insulation that has settled to half its intended depth. The east side of town, where new development has pushed toward the foothills, features standard batt insulation in framed walls, but attics there still absorb full sun all day with minimal shade relief.
One detail we’ve learned from years of work in north Redlands: the mature citrus trees that make the neighborhood so pleasant also drop leaves and debris that clog attic ventilation screens. Poor airflow through those screens degrades insulation faster and makes the attic even hotter. We check ventilation screens on every Redlands attic job, because a blocked screen undoes half the benefit of new insulation.
Our Main Redlands Services
Two services account for most of the calls we take from Redlands homeowners. Here’s what each one involves in this city.
Attic Insulation in Redlands
Redlands attics are where the real energy loss happens. We assess the existing material, check for settled or compressed areas, evaluate ventilation, and then recommend either a top-off or full removal and replacement. In older homes near downtown, we often find the original insulation has compacted to R-value levels far below what modern code expects. Mature tree shade on the north side changes the calculation versus full-sun exposure on the east side, so we never assume one answer fits every Redlands house. We carry fiberglass batts, blown-in material, and radiant barriers to match whatever the attic actually needs. Attic Insulation in Redlands has the full breakdown of what this job looks like here.
Spray Foam Insulation in Redlands
Spray foam earns its keep in Redlands when air-sealing matters as much as R-value. Older Redlands homes leak air through rim joists, cantilevered floors, and attic bypasses, which means cooled air escapes and hot air streams in all summer. Closed-cell foam seals those gaps and adds structural rigidity, while open-cell works well in attics and sound-sensitive walls. We install Icynene and Demilec, two of the most performance-tested spray foam brands in North America, and our crew handles the application in-house. For Redlands homes with addition remodels or cathedral ceilings, spray foam is often the only way to hit performance targets without tearing out drywall. Spray Foam Insulation in Redlands covers pricing, applications, and what to expect on installation day.

Blown In Insulation in Redlands
Blown in insulation is the most common fix we recommend for Redlands attics because it solves the core problem this climate creates: heat gain through an under-insulated ceiling. In a 1950s or 1960s tract home with original insulation, the existing material has usually settled to a fraction of its original depth, leaving large areas with almost no thermal barrier at all. We blow loose-fill material across the entire attic floor to a consistent depth, which restores the R-value in one pass and cuts the heat streaming into the house. Our Blown In Insulation service is what most Redlands homeowners end up booking after an attic assessment.
Cellulose Insulation
Signs you need it
Your attic insulation measures under six inches deep, or you can see the ceiling joists poking through the existing material.
What it costs in Redlands
Cellulose blow-in for a typical Redlands attic runs $1,500 to $3,000 depending on square footage, access, and the depth needed to hit current R-value targets.
How we do it
We air-seal the attic floor penetrations first, then blow GreenFiber cellulose to a consistent depth using a calibrated hose and density checks as we go.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic stay hot well into the evening in summer, or your monthly cooling bill has climbed noticeably over a few seasons.
What it costs in Redlands
Blown in attic insulation for a standard Redlands ranch home typically runs $1,200 to $2,800, with price moving on attic size and prep work.
How we do it
We set up protective floor covering, run the hose into the attic access, and blow material evenly across the full attic floor, including around trusses and over the top plates.
Blown In Fiberglass Insulation
Signs you need it
You want the higher R-value per inch that fiberglass offers, or you’re topping off existing fiberglass batts that have lost loft.
What it costs in Redlands
Blown in fiberglass in Redlands attics runs $1,400 to $3,200, with the final number tied to depth target and square footage.
How we do it
We blow loose-fill fiberglass using Johns Manville or Knauf material, layering it to the R-value specified in your assessment and checking depth with markers throughout the attic.
Loose Fill Insulation
Signs you need it
Your attic has uneven insulation coverage, bare patches, or areas where old material has shifted away from the eaves.
What it costs in Redlands
Loose fill insulation for a Redlands attic runs $1,300 to $2,900, with the range reflecting attic square footage and how much existing material needs removal first.
How we do it
We remove or level compromised material, seal bypasses, then blow loose fill to an even depth, checking density and coverage with a depth gauge as we finish each section.
What Blown In Insulation Costs in Redlands
| Item | Typical range in Redlands |
|---|---|
| Cellulose blow-in attic | $1,500 – $3,000 |
| Blown in attic insulation | $1,200 – $2,800 |
| Blown in fiberglass attic | $1,400 – $3,200 |
Is blown in insulation worth it for a Redlands attic?
Yes, and in Redlands the payback is faster than coastal areas because cooling season dominates. Restoring attic insulation depth cuts heat gain into the house, which means your air conditioner runs less from June through October. Most Redlands homes we assess are under-insulated enough that the improvement is noticeable the first summer.
How long does blown in insulation take in Redlands?
A typical Redlands attic takes one working day from setup to cleanup, including air-sealing and depth checks. Larger attics or homes needing old material removal first can run into a second day. Call (866) 271-1602 and we’ll give you a straight time estimate based on your attic’s square footage.

| Blown in attic insulation | $1,200 – $2,800 |
| Blown in fiberglass attic | $1,400 – $3,200 |

| Open-cell spray foam attic | $3,000 – $6,500 |
What pushes a Redlands job toward the higher end of those ranges? Attic access matters more than people expect: pull-down stairs in a tight hallway closet make material handling slower than a walk-up attic in a raised ranch. Removal of old, degraded material adds disposal cost. We quote upfront pricing on every Redlands job after an on-site assessment, so the number we give you is the number on the invoice, not a starting point.

FAQs About Insulation Company in Redlands
For most insulation-only jobs in Redlands, no permit is required. The exceptions come when the work involves structural changes, like converting an attic to living space or cutting new roof vents. We confirm current Redlands code requirements before starting any job that could trigger a permit, so you’re not left handling paperwork surprises mid-project.
In most cases we can have a crew on your Redlands property within one to two weeks of the estimate. Attic insulation and blown-in jobs usually fit into the schedule faster than full spray foam work, which requires more preparation. Call (866) 271-1602 and we’ll give you a realistic start date based on the scope.
We assess older Redlands homes case by case. Knob-and-tube wiring in the attic changes the approach, since insulation cannot be blown directly over live knob-and-tube conductors. We’ll inspect the attic, identify what’s active, and recommend a safe sequence that may include an electrician’s sign-off before we insulate. This is a common situation in the historic downtown neighborhoods, so it’s part of our standard assessment process.
If your Redlands home is uncomfortable, hot upstairs, or expensive to cool, the fix usually starts in the attic. Call Fontana Insulation at (866) 271-1602 for a free, no-obligation estimate. We’ll assess what’s there now, explain what your home actually needs, and give you a number you can plan around.

— Holly Mercer"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
