Insulation Company in Rowland Heights, CA
Blown in insulation is the workhorse fix for Rowland Heights homes built between the 1960s and 1990s, because most of them still have original fiberglass batts that have slumped, compressed, or turned to dust in the attic heat. Summer attic temperatures here routinely pass 140°F, so cooling-season performance drives every material decision we make. Hollywood Insulation Co has served Rowland Heights since 2018, and we install all three methods: blown in, spray foam, and batt. Call (866) 605-6949 for a free estimate on any of them.
Why Rowland Heights Homes Are Different
Rowland Heights sits in the hot, dry eastern San Gabriel Valley, where summers run long and regularly push above 95°F from July through September. Winters are mild, so the job here is not heat retention. It is attic heat gain, duct insulation, and a building envelope that can actually reject the afternoon sun. That changes the material conversation completely. A homeowner in a coastal, marine-layer zip code might never need to think about a radiant barrier. In Rowland Heights, it is often the first thing we recommend.
The housing stock reinforces this. Most homes are 1960s to 1990s single family tract houses plus a band of newer hillside custom builds. The tract homes almost always started with R-11 or R-13 fiberglass batts in the attic, and forty or fifty years of thermal cycling have compressed those batts to a fraction of their rated R-value. In the hillside neighborhoods near Pathfinder Road and Fullerton Road, slab on grade homes built in the 1970s are a recurring case study for us: attic air handlers on poorly sealed platforms, original batts blackened with dust, and enough air leakage to make the cooling system work double shifts. Those are not rare finds. They are the typical finds.
Our Main Rowland Heights Services
Rowland Heights homeowners call us most about two things: bringing an under insulated attic up to spec and using spray foam to close persistent air leaks and hot spots. Here is how each one plays out locally.
Attic Insulation in Rowland Heights
Attic work in Rowland Heights usually means removing compressed, dust-caked fiberglass and replacing it with material that holds its R-value through 140°F attic summers. We see a lot of original batts in 1970s hillside homes that look thick from the hatch but measure at half their rated performance once you actually pull a sample and test it. The fix is either blown in cellulose or fiberglass, or a radiant barrier added to the roof deck, depending on how the home is framed. For the full local breakdown, see our Attic Insulation in Rowland Heights page.
Spray Foam Insulation in Rowland Heights
Spray foam earns its keep in Rowland Heights where air leakage meets real heat: around attic air handlers, recessed light fixtures, and the rim joists of hillside homes where hot outside air pressurizes the envelope. We install both Icynene open-cell and Demilec closed-cell systems, and the choice between them depends on whether the bigger problem is air movement or heat gain. The wrong foam in the wrong place wastes money. The right foam cuts cooling bills and stops hot spots for good. Details are on our Spray Foam Insulation in Rowland Heights page.

Blown In Insulation in Rowland Heights
Blown in insulation is the most common service we perform in Rowland Heights because it matches the housing stock perfectly. Most attics here were built with thin fiberglass batts laid between ceiling joists, and blown in material, either cellulose or fiberglass, fills the gaps, the corners, and the irregular cavities that batts never sealed properly. In a Rowland Heights summer, the difference is measurable: a properly filled attic keeps the ceiling surface noticeably cooler and takes real load off the air conditioner. Our Blown In Insulation service covers both material types, and we help every homeowner choose which one fits their attic.
Cellulose Insulation
Signs you need it
Your existing attic insulation is thin, uneven, or dust-caked, and upstairs rooms climb five to ten degrees hotter than downstairs by mid afternoon.
What it costs in Rowland Heights
Cellulose blown in attic coverage in Rowland Heights typically runs $1.10 to $2.10 per square foot depending on target depth and access.
How we do it
We remove or level the old material, air seal visible penetrations, then blow GreenFiber cellulose to the depth required for the R-value your home needs.
Blown In Attic Insulation
Signs you need it
You can see the ceiling joists through the existing insulation, or your attic access hatch feels hot to the touch on a summer afternoon.
What it costs in Rowland Heights
Typical blown in attic insulation projects in Rowland Heights land between $1,500 and $3,500 for a standard 1960s to 1990s tract home attic.
How we do it
We verify the existing depth, vacuum or level where needed, seal bypasses around ducts and wires, then blow new material to a consistent, measured depth across the entire attic floor.
Blown In Fiberglass Insulation
Signs you need it
Your attic has older fiberglass batts that have been flattened by storage boxes or foot traffic, creating bare spots and thin zones with little thermal resistance left.
What it costs in Rowland Heights
Blown in fiberglass runs $0.80 to $1.60 per square foot in Rowland Heights, making it the lighter and more economical option for shallow attic cavities.
How we do it
We blow loose fill fiberglass at a controlled density, using depth markers to keep the R-value uniform even in hard to reach eaves and corners.
What Blown In Insulation Costs in Rowland Heights
| Item | Typical range in Rowland Heights |
|---|---|
| Cellulose blown in, per sq ft | $1.10 – $2.10 |
| Fiberglass blown in, per sq ft | $0.80 – $1.60 |
| Standard attic, full project | $1,500 – $3,500 |
How long does blown in insulation last in Rowland Heights heat?
Cellulose and fiberglass both hold their R-value for decades as long as they stay dry, but attic heat and air movement can settle blown material over time. We install to compensate for that settlement.
Is blown in insulation enough for a Rowland Heights summer?
For most homes, yes. Blown in insulation to R-38 or R-49 in the attic plus basic air sealing is enough to stop most heat gain and even out room temperatures. Call (866) 605-6949 to talk through your attic specifically.

What Rowland Heights 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."
