Fast, Reliable Attic Insulation Across Pomona
Attic insulation in Pomona usually costs between $1,800 and $4,600 for a full attic upgrade, with top-ups running $900 to $2,200 and radiant barrier installation at $1,500 to $3,000 depending on attic size. We know Pomona’s housing stock well, from the pre-war bungalows off Garey Avenue to the newer tracts near Phillips Ranch. Our crews get to most Pomona jobs same-day or next-day, and every estimate is free. Call (866) 858-4033 to get a number specific to your attic.
Phil Darnell started Brea Insulation with one goal: be the insulation contractor Pomona homeowners call when the last guy didn’t fix the real problem. We’re not a handyman service that adds insulation as a side line. Insulation is the only thing we do, and that focus shows in how we diagnose attics, match materials, and install. You get a specialist, not a generalist.
Why Pomona Homeowners Call Brea Insulation First
Our local reputation in Pomona is built on jobs where other contractors either walked away or did the bare minimum. Shallow attics in 1920s bungalows. Knob-and-tube wiring buried under old loose fill. Radiant barrier installs that actually need ventilation upgrades first. We handle all of it under one roof because we carry eight manufacturer lines including Owens Corning, Icynene, Demilec, and GreenFiber. That means the material recommendation comes from your home’s actual conditions, not from whatever is cheapest to stock.
Response time matters in Pomona’s inland heat. When attic temperatures climb past 140 degrees during a San Gabriel Valley summer, waiting two weeks for a contractor isn’t practical. We schedule Pomona jobs quickly and show up when we say we will. Phil Darnell insists on it. Homeowners from Lincoln Park to Westmont tell us the same thing: the estimate was clear, the crew knew the house type, and the temperature difference was noticeable within days.
We also understand Pomona’s split housing stock. The bungalows in 91766 and 91767 need a completely different approach than the tract homes in 91768. A 1940s home with plaster-and-lath walls and a low-pitch attic can’t take the same blown-in depth as a 1990s ranch with standard trusses. Knowing the difference before we open the attic door saves you money and prevents rework.
Radiant Barrier in Pomona
Radiant barrier in Pomona is the single most requested attic upgrade we install, because Pomona’s summers regularly push into the 90s and 100s and attic heat gain is the dominant comfort problem, not winter heat loss. A radiant barrier is a reflective material installed under the roof deck that reflects radiant heat before it can transfer into your insulation and living space. In Pomona’s climate, that can reduce attic temperatures by 20 to 30 degrees, which means less strain on your AC and noticeably cooler upstairs rooms. The Attic Insulation team at Brea Insulation installs radiant barriers in tandem with ventilation checks, because a barrier without proper airflow just traps heat.
When Radiant Barrier Makes Sense Here
If your Pomona home has ductwork running through the attic, a radiant barrier is one of the highest-impact upgrades you can make. Ducts sitting in a 150-degree attic lose a significant amount of cooled air before it reaches your rooms. Radiant barrier drops that attic air temperature enough to make your system measurably more efficient. Homes on the west-facing side of Towne Avenue or in the exposed sections of Phillips Ranch see the biggest gains.
Radiant Barrier Costs in Pomona
For Pomona attics, radiant barrier installation typically runs $1,500 to $3,000 depending on roof square footage and whether we’re also addressing ventilation. Older bungalows with low-pitch roofs and minimal attic access will be on the higher end because installers work in tight quarters. Call (866) 858-4033 and we’ll measure the attic and give you a precise number.
Attic Cleaning Services in Pomona
Attic cleaning services in Pomona are often the necessary first step before any new insulation goes in, especially in the older homes that make up so much of 91766 and 91767. Decades of dust, rodent droppings, old loose fill, and sometimes asbestos-containing vermiculite need to be removed before you can air-seal and insulate properly. We use commercial vacuums with HEPA filtration so contaminants don’t get pulled into your living space. The job costs $1,100 to $2,800 in Pomona depending on attic size, access difficulty, and what’s actually up there.
Old Loose Fill and Wiring Removal
In Pomona’s pre-war bungalows, we routinely find old loose fill hiding knob-and-tube wiring that was never meant to be buried. That combination is a fire hazard and a Title 24 failure waiting to happen. We remove the fill, assess the wiring, and coordinate re-routing before any new insulation touches the joists.
Contamination and Odor Remediation
Rodent activity in Pomona attics is common, especially in older homes near mature trees and open spaces like the ones around Ganesha Park. Droppings and urine-soaked insulation don’t just smell, they degrade indoor air quality. Our cleaning process removes contaminated material, sanitizes the decking, and preps the space for fresh insulation.

Trusted Brands We Service in Pomona
We’re factory-authorized installers for Owens Corning, Icynene, Demilec, GreenFiber, and four other manufacturers. That matters in Pomona because local homes span 100 years of construction, and no single material is right for every attic. A 1920s bungalow with a low-pitch roof and limited access needs different material than a 2000s tract home in 91768. We stock the right products for Pomona jobs and can pull from eight brand lines on short notice without waiting on a distributor. When a Pomona homeowner needs R-38 batts in a cramped rafter bay, we have them. When they need Icynene open-cell foam for an air-sealing retrofit, we have that too.
Common Attic Insulation Problems We See in Pomona Homes
- Knob-and-tube wiring buried under blown-in insulation: We find this constantly in Pomona’s 1920s-1950s housing stock. Loose fill packed around old wiring creates a fire risk and fails Title 24 inspection. The fix is removal, air-sealing, and re-routing before new insulation goes in.
- Shallow rafter bays with insufficient R-value: Pre-war bungalows in 91766 and 91767 often have rafter bays too cramped for standard blown-in depth. The result is uneven coverage and R-values far below current code. We fit batt insulation and radiant barrier instead, sized to the actual cavity.
- Radiant barrier without ventilation: Some Pomona homeowners get a radiant barrier installed by a contractor who never addressed attic ventilation. Without proper exhaust airflow, the barrier traps heat and works against you. We check ridge vents, gable vents, and soffit intake as part of every radiant barrier quote.
- No attic air-sealing before insulation: Inland SGV heat pushes hot air through top plates, can lights, and chase penetrations. Insulating over those leaks doesn’t fix the problem. We air-seal first, then insulate. That sequence is why our attic upgrades hold up through Pomona’s hottest weeks.

FAQs About Attic Insulation in Pomona
Yes. We do this on Pomona bungalows regularly, but the wiring has to be addressed before insulation goes in, because burying live knob-and-tube under loose fill or batts is a fire hazard and a Title 24 failure. Our process is to remove existing insulation, air-seal the top plates, coordinate wiring re-routing, and only then install new material. In a 1940s bungalow off Towne Avenue, our crew found knob-and-tube running through bare joists with just 2 inches of old fill. We cleared it, re-routed the wiring safely, and installed Owens Corning R-38 batts plus radiant barrier. The homeowner saw a 10-degree drop in upstairs rooms during the next heat wave. Call (866) 858-4033 and we’ll assess your wiring situation before quoting.
For most Pomona homes, the best result comes from a combination: air-sealing plus R-38 insulation plus a radiant barrier to reflect heat before it reaches the insulation. Blown-in fiberglass or cellulose handles the R-value, but it doesn’t stop radiant heat transfer the way a reflective barrier does. Given Pomona’s 90-100 degree summers and intense sun exposure, radiant barrier is the piece that makes the most noticeable difference. We’ll look at your attic, venting, and duct layout before recommending a specific setup. The estimate is free.
If you can see rodent droppings, old loose fill that’s compressed or discolored, dust caked on the decking, or you smell something musty when you open the attic hatch, cleaning comes first. In Pomona’s older homes, especially those around the tree-lined streets of Lincoln Park and Ganesha Park, rodent activity in attics is common. Installing new insulation over contaminated material locks in the problem. We’ll tell you honestly whether cleaning is required or if we can go straight to top-up and air-seal. Call (866) 858-4033 for an attic inspection.
Yes, but it requires a different method than standard blown-in. Pomona’s pre-war and mid-century bungalows in 91766 and 91767 often have rafter bays too shallow for the kind of depth you’d get in a trussed attic. We fit batts sized to the cavity and use radiant barrier plus air-sealing to compensate for the lower R-value. Cramped access means installers work on their knees or bellies, which is slower and costs a bit more, but it’s entirely doable. We’ve done dozens of these jobs in Pomona and know what fits before we start.
Most Pomona ranch homes with standard access take one full day for air-sealing and insulation installation. If we’re also doing attic cleaning and removing old material, plan for two days. Radiant barrier adds about half a day depending on roof geometry and attic height. Tight attics in old bungalows run longer because everything is slower in a 24-inch clearance. We’ll give you a firm timeline when we do the estimate, and we don’t leave the job half-finished for another schedule block.
If you’re losing cool air through your attic every summer, we should talk.
