Insulation Company in Redlands, CA
Blown in insulation is the fastest way to fix the two biggest comfort problems in Redlands homes: brutal attic heat gain in summer and the fine dust that Santa Ana winds push through every unsealed gap. Most of the older houses we work on in Redlands, especially the citrus-era Craftsman and Spanish Colonial homes around downtown, have either no attic insulation or a thin layer that settled decades ago. Hollywood Insulation Co has served Redlands since 2018, and we install blown in insulation, attic insulation, and spray foam using the method that actually fits your home’s construction, not whatever is easiest. Call (866) 605-6949 for a free estimate.
Why Redlands Homes Are Different
Redlands sits in the Inland Empire’s smog belt below the San Bernardino Mountains, where summer afternoons regularly push past 100°F and Santa Ana wind events can swing temperatures by 50 degrees in a day. That means insulation here has to perform two jobs at once: blocking radiant heat pouring through the roof deck, and stopping the fine desert dust and soot that wind events drive into every unsealed attic penetration. A bat of fiberglass installed in a coastal climate would handle one of those tasks. In Redlands, it has to handle both.
The housing stock makes this even more specific. The historic core in ZIP 92373, around Smiley Heights and the streets near downtown, is full of 1890s to 1920s Craftsman and Spanish Colonial homes built by the citrus boom. Many of these houses still have knob-and-tube era wall cavities, original redwood or cedar siding that has shrunk over a century of dry heat, and citrus-grove-era attic vents that let hot afternoon air pour directly into the top plate. A few blocks east, ZIP 92374 is mostly post-war and 1960s to 1980s tract housing with builder-grade R-11 batts that have sagged and compressed under decades of attic heat. Two very different building envelopes, often within a five-minute drive. A technician who only knows one insulation method will misdiagnose one of them.
Our Main Redlands Services
Redlands homeowners call us most often about two things: attic insulation for older homes that are losing conditioned air through the ceiling, and spray foam for houses where air sealing matters as much as R-value. Both have their own dedicated Redlands pages, and both start with a home inspection that looks at your actual attic, not a generic checklist.
Attic Insulation in Redlands
Older Redlands homes lose most of their conditioned air straight up through the attic, especially when the original insulation is missing, compressed, or blown thin. We inspect what is already up there, check the top plate for gaps the wind finds, and recommend the right material for your house. In a 1920s Craftsman near Smiley Heights, that might mean air sealing first and blown in cellulose second. In a 1970s tract home in ZIP 92374, it might mean pulling compressed R-11 batts and starting fresh with a higher R-value. See the full breakdown on our Attic Insulation in Redlands page.
Spray Foam Insulation in Redlands
Spray foam earns its keep in Redlands because it combines high R-value with a true air barrier, which matters when Santa Ana winds are pushing dust through every crack in your attic and exterior walls. We install both Icynene and Demilec systems, open-cell and closed-cell, and the choice depends on your roof assembly, your ductwork location, and whether moisture control is a concern. Our Spray Foam Insulation in Redlands page covers the differences, the costs, and the signs your house is a good candidate.

Blown In Insulation in Redlands
Blown in insulation is the workhorse solution for Redlands attics because it fills the irregular cavities, gaps, and odd-shaped spaces that batts leave open. In a 1920s citrus-era home where the rafters are hand-cut and the spacing is uneven, loose fill settles into every corner and creates a continuous thermal blanket that compressed batts simply cannot. In newer tract homes, blown in insulation lets us bring an under-insulated attic up to current R-value recommendations in a single day without removing the existing material. We cover the full method on our Blown In Insulation hub page; below is what matters most in Redlands.
Cellulose Insulation
Signs you need it
Your attic insulation is thin, settled, or missing entirely, and you want a dense, fire-resistant fill made from recycled paper rather than fiberglass.
What it costs in Redlands
Blown in cellulose typically runs $1.50 to $3.20 per square foot installed in Redlands attics, depending on depth and access.
How we do it
We air-seal the top plate and penetrations, then blow GreenFiber cellulose to the target depth with a high-volume machine, checking depth markers as we go.
Blown In Attic Insulation
Signs you need it
Rooms on the top floor run 10 to 15 degrees hotter than the rest of the house in summer, and your existing attic insulation looks patchy or compressed.
What it costs in Redlands
Blown in attic insulation ranges from $1.50 to $3.20 per square foot in Redlands, with attic prep and air sealing priced separately based on what we find.
How we do it
We prep the attic, seal the bypasses, and blow loose fill to the specified depth and R-value, using a gauge to verify consistent coverage across every bay.
Blown In Fiberglass Insulation
Signs you need it
You want a lightweight, non-settling loose fill option that performs well in awkward attic spaces and around irregular framing.
What it costs in Redlands
Blown in fiberglass runs $1.50 to $3.20 per square foot installed for Redlands attics, with final price set by target R-value and access.
How we do it
We install blown fiberglass from brands we carry to the specified depth, fluffing it to the manufacturer’s coverage chart so you get the R-value you paid for.
What Blown In Insulation Costs in Redlands
| Item | Typical range in Redlands |
|---|---|
| Blown in insulation (labor + material) | $1.50 – $3.20 per sq ft |
| Air sealing before blown in | $0.50 – $1.00 per sq ft |
| Attic prep and cleanup | $250 – $650 flat |
What moves the price in Redlands is access. Homes in ZIP 92373 with old citrus-era attics and narrow hatches take longer to prep, and homes with knob-and-tube wiring need careful clearance work before we blow anything. We quote the full job upfront, and you know the number before we start. Call (866) 605-6949 for an exact quote on your attic.
Is blown in insulation worth it in Redlands?
Yes, for most attics. Blown in insulation pays for itself fastest in Redlands because extreme attic heat forces HVAC systems to work harder, and a continuous loose fill layer directly reduces that load. Most homeowners notice the difference within the first full summer.
How long does blown in insulation last in Redlands?
Cellulose and fiberglass both hold up well in Redlands if the attic stays dry and the Santa Ana dust is sealed out at the source. Cellulose settles slightly over time and may need topping up after 15 to 20 years. Call (866) 605-6949 and we’ll check your depth free.
Brands We Service in Redlands
We carry eight manufacturer brands across every major insulation category, so the material is chosen for your Redlands home, not for what is on the truck. Rockwool mineral wool, CertainTeed fiberglass, Icynene and Demilec spray foam, and GreenFiber cellulose are all in our regular rotation here, with common Redlands attic materials stocked for fast turnaround.

Prices in Redlands move most on access and age. A 1920s attic with a 22-inch hatch, hand-cut rafters, and knob-and-tube wiring costs more to prep than a clean 1980s attic with a pull-down stair, because the work is slower. Every quote is itemized before we start, and the number on the quote is the number you pay.

Most insulation replacement and attic upgrades in Redlands do not require a permit because they are considered maintenance on an existing home. If you are adding spray foam to a new addition or doing work tied to a remodel with open permits, that is a different story. We will flag any permit issue during the estimate so there are no surprises.
Yes, and we have done many of them in the historic neighborhoods. Knob-and-tube wiring requires extra care in attic work because covering the wires with insulation impacts their heat dissipation, and we take that seriously. We will walk you through the options, including leaving safe clearance or coordinating with an electrician if the wiring should be addressed first.

What Redlands Customers Say
"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"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"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."
