Insulation Company in Highland, CA
Blown in insulation is the most common upgrade we handle in Highland, and for good reason: most homes in ZIP 92346 were built between the 1950s and 1980s with attic insulation that was barely adequate when it was installed and is badly compacted now. Highland’s summer highs routinely push past 100°F, which turns under-insulated attics into heat traps that force air conditioners to run constantly. Fountain Valley Insulation has served Highland since 2014, matching the right blown-in material to each home rather than dumping whatever is on the truck and calling it done.

Why Highland Homes Are Different
Highland sits deep in the Inland Empire, east of Los Angeles, where the diurnal temperature swing is one of the widest in Southern California. A summer day can hit 105°F and drop to the low 60s overnight. Insulation here has to handle both extremes, which is why we pay close attention to attic ventilation whenever we upgrade blown-in coverage. Poor venting in a Highland attic doesn’t just make the house hotter; it traps moisture that settles into insulation fibers, degrades R-value, and shortens the material’s useful life.
The housing stock adds another layer. Much of Highland is made up of single-story tract homes from the 1950s through the 1980s. Many still have their original R-11 or R-13 attic insulation, and garage ceilings are frequently uninsulated altogether. We regularly find insulation so compacted by dust and decades of heat cycling that it performs closer to R-5. Homes along the foothills near the Santa Ana River wash face an additional problem: dry Santa Ana winds push fine dust and debris through attic vents, which settles into loose-fill and causes it to pack unevenly. The result is hot spots and cold spots in the same house, and R-value that drops faster than homeowners expect.
One more quirk we see in Highland: a surprising number of attics still have the original blown-in rock wool from the 1960s and 1970s, often mixed with rat droppings and broken vent screens. That material has to come out before anything new goes in. Skipping removal means the new insulation just sits on top of a compacted, contaminated base, and the homeowner pays twice.
Our Main Highland Services
Blown-in insulation is the workhorse for most Highland homes, but two other services come up constantly. Here’s what each involves in this city.
Attic Insulation in Highland
Attic insulation in Highland is the single highest-impact upgrade most homeowners can make, because the attic is where heat builds first and lingers longest. Most of the attics we enter here have blown-in material that has settled to half its original depth, or bare spots where contractors from decades ago simply didn’t reach the eaves. We remove compacted material where needed, air-seal the attic floor, and install fresh coverage matched to the home’s orientation and venting. See the full breakdown at Attic Insulation in Highland.
Spray Foam Insulation in Highland
Spray foam is the right answer for specific Highland situations, not every situation. Homes with uninsulated garage ceilings, knee walls, or attics that double as storage often benefit from closed-cell foam’s air-sealing properties. It’s also worth considering if you live near the foothills and deal with dust intrusion through vents, because foam seals those gaps rather than filtering the dust. We install spray foam through Spray Foam Insulation in Highland, using Icynene and Demilec products.

Blown In Insulation in Highland
Blown in insulation in Highland is the most direct way to cut cooling costs in homes built before modern energy codes. The combination of 1950s – 1980s single-story tract houses, original R-11 or R-13 attic coverage, and summer temperatures that stay above 100°F for weeks means attics here become ovens that radiate heat into living spaces all evening. Blown-in material lets us reach every corner and wall cavity, including spots batts can’t reach, which is why we recommend it so often in ZIP 92346. See our full Blown In Insulation page for material details, or keep reading for what it costs and how we handle the work in Highland specifically.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the joists, and your cooling bill stays high even after the AC is serviced.
What it costs in Highland
Cellulose insulation in Highland typically runs $1.10 to $2.80 per square foot installed, depending on depth and whether old material must be removed first.
How we do it
We air-seal bypasses, protect vents, then blow cellulose to the target depth, checking density with a depth gauge as we go.
Blown In Fiberglass Insulation
Signs you need it
Rooms over the garage or at the far end of the house are consistently 5 – 10 degrees warmer in summer, and the attic has bare patches between joists.
What it costs in Highland
Blown in fiberglass in Highland generally costs $0.90 to $2.40 per square foot installed, with the lower end applying to open attics with easy access.
How we do it
We remove compacted or contaminated material, seal penetrations, and blow fiberglass to the R-value the home needs for Highland’s climate zone.
What Blown In Insulation Costs in Highland
| Item | Typical range in Highland |

| Blown in fiberglass (attic, open access) | $0.90 – $2.40 per sq ft |
| Cellulose insulation (attic) | $1.10 – $2.80 per sq ft |
| Removal of old, compacted insulation | $0.80 – $1.50 per sq ft |
How much does blown in insulation cost in Highland?
Most Highland homes fall between $1,800 and $4,200 for a full attic blow-in, depending on square footage and whether we remove old material first. Call (833) 390-3099 for a line-item quote; estimates are free.
Can you do blown in insulation the same day in Highland?
Yes, in most cases. A standard single-story Highland attic takes one crew four to six hours, so same-day completion is realistic when we’re not removing old insulation. We’ll confirm the timeline when we give you the estimate.

FAQs About Insulation Company in Highland
Most Highland jobs are scheduled within one week, and during fall and winter we can often get a crew out the same or next day. Emergency situations, like a ceiling that has been opened up by a leak, get priority routing. Call (833) 390-3099 and we’ll give you a real arrival window, not a vague “sometime next week.”
Most insulation retrofits in existing homes do not require a permit in Highland, but new construction and additions do. If your project falls under a building permit, your general contractor typically handles the paperwork. We’re happy to coordinate with your GC and provide the insulation specs they need for the permit file.
Yes. We remove compacted rock wool, fiberglass, and whatever else has accumulated over 40 to 70 years of Highland heat, then air-seal and install new material to current R-value recommendations. Older homes are actually where we do some of our most impactful work, because the performance difference is dramatic. Call (833) 390-3099 for a free attic inspection and estimate.

What Highland Customers Say
"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."
— Justin Chen"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Carmen Reyes"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Hector Vargas
