Fast, Reliable Attic Insulation Across Highgrove
Highgrove’s summer heat pushes attic temperatures past 140°F, and if your home was built between the 1950s and 1980s, there’s a good chance the insulation up there is doing almost nothing. We’re Orange County Insulation, and we only do insulation. No roofing, no HVAC, no remodeling. That means when we show up to a Highgrove home, we’re not guessing at the problem, we’re fixing it with the right material the first time. Call (877) 680-3557 for a free estimate and we’ll tell you exactly what your attic needs and why.
Why Orange County Insulation Is Highgrove’s Preferred Attic Insulation Company
We’ve worked in enough Highgrove ranch homes to know the construction patterns here. These houses went up fast in the postwar building boom, and attic insulation was often an afterthought, a thin layer of fiberglass or nothing at all. Homeowners call us after years of fighting rooms that never cool down, and we find compressors running constantly while hot air pours through the ceiling. Our team is led by Noel Carrasco, and every estimate and every job gets his direct attention. We don’t send a salesperson to high-pressure you into spray foam. We send someone who can explain why cellulose makes sense for one attic and closed-cell Demilec makes sense for another. Highgrove homeowners get straight answers about what’s actually wrong up there.
Attic Insulation Removal in Highgrove
Attic Insulation Removal in Highgrove is more than pulling out old batts and hauling them to the truck. It’s the first real fix for homes that still carry original insulation from the Eisenhower and Reagan eras, material that’s been compressed, chewed through by rodents, and saturated with decades of wind-driven dust. In a 1962 ranch off Cypress Avenue, we found the original fiberglass batts compressed to R-7 and dust streaks along the top plate from decades of Santa Ana winds. We air-sealed every penetration with foam, installed a radiant barrier, and blew in Owens Corning fiberglass to R-38, dropping the attic temperature by 25°F on a 105°F day. That’s what removal actually accomplishes. It clears the deck so the real work can happen.
When Removal Makes Sense
If your insulation is original, it’s done. Fiberglass loses its loft and settles, dropping from R-30 or R-19 down to R-7 or less. Rodent activity and water intrusion from old roof penetrations also ruin otherwise decent material. Removal is the only chance to inspect the top plates, wire penetrations, and can lights for the gaps that let Santa Ana dust pour in.
What Removal Costs in Highgrove
Full removal on a typical 1,200 to 1,800 square foot Highgrove ranch runs $600 to $1,400 depending on depth, contamination, and how much is up there. That includes cleanup and prep for new material. Leaving failed insulation in place while you add more on top just buries the problem and keeps the dust channels open.
Insulation Contractors in Highgrove
Hiring Insulation Contractors in Highgrove means choosing between general contractors who sub it out and a company that does nothing else. We’re the latter. Our crews install batts, blown-in, and spray foam every week, and they know what happens to each material in an Inland Empire attic in August. A generalist might offer you the one product their supplier stocks. We stock and install from eight brands: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. The right material for your home, not the easiest one for us to install.
Retrofit Expertise on Older Ranches
Highgrove’s housing stock is almost all single-story ranch and tract homes from the 1950s through the 1980s. Retrofitting these attics means working around older framing, narrow eaves, and original can lights that may not be IC-rated. We solve that with proper baffles before blowing in any material, so airflow from soffit vents doesn’t get buried.
New Builds and Light Commercial
Builders and remodelers in the Inland Empire call us because we can supply open-cell Icynene for interior walls and closed-cell Demilec for unvented attics without switching subs. One crew, one point of contact, no coordination mess.
Trusted Brands We Service in Highgrove
We don’t have a single brand we’re married to. Our Attic Insulation team works with Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber because Highgrove attics aren’t all the same shape. A ranch with a vented attic and good soffit airflow might get GreenFiber cellulose blown to R-38. A home with no attic at all, just a flat roof with a cavity, might need closed-cell Demilec to hit performance without eating headroom. Rockwool makes sense when the homeowner wants fire resistance along a shared property line, which matters in denser parts of Highgrove. We stock the materials we install, which means we’re not waiting on a distributor when your attic is already opened up.
Common Attic Insulation Problems We See in Highgrove Homes
- Compressed or missing original batts from the 1950s-1970s. R-values on these houses routinely measure R-7 to R-11 when the code at the time called for R-19 or better. The material has flattened under its own weight and the hot attic air just walks through it.
- Wind-driven dust infiltration during Santa Ana events. Unsealed top plates and recessed lights pull fine dust through the attic floor into the living space. We see gray streaks along the framing that mark exactly where the air has been moving for sixty years.
- Inadequate attic ventilation. Hot air stacks up in the attic and bakes the underside of the roof deck, degrading whatever insulation remains and making the air conditioner work hard all afternoon. Radiant barrier and baffle work fixes this, but only if the old material is removed or redistributed first.
- Builder-grade insulation in 1980s tract homes. These houses got the minimum legal thickness and often no air sealing at all. The insulation is thin, the gaps are everywhere, and the homeowner is paying to cool the attic.
Pricing for Attic Insulation in Highgrove, CA
A typical blown-in attic insulation job for a 1,400 square foot Highgrove ranch runs $1,800 to $3,200.

FAQs About Attic Insulation in Highgrove
Air sealing matters more than insulation in Highgrove because the Santa Ana winds push air through every gap in your attic floor, carrying fine dust and hot air into the house. Adding R-38 on top of a leaky ceiling is like putting on a heavier coat but leaving the zipper open. Sealing top plates, wire holes, and can lights with foam stops the airflow, and then the insulation does its actual job. Call (877) 680-3557 for a complete attic inspection and quote.
We recommend R-38 as a minimum for vented attics in Highgrove, which usually means about 12 to 14 inches of blown-in fiberglass or cellulose. Some newer homes and unvented attics with closed-cell spray foam can achieve effective performance with less depth because the foam also acts as an air barrier.
If your house predates 1990 and the attic has never been touched, you likely have original insulation. Look for thin, dark, flattened batts between the joists, often with a brown paper backing. If the material looks compacted and dusty and measures under six inches, it’s performing below R-19 and should come out.
Yes. Insulation removal is one of our core services, and we do it on almost every older Highgrove home we upgrade. We vacuum out the old material, then the crew seals every penetration and installs baffles before blowing in fresh material. The whole job on a typical ranch takes one day.
We install Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That breadth lets us match the material to the attic, not the homeowner to whatever we have on hand. For a dusty, windy Highgrove attic, that often means GreenFiber cellulose for its air-blocking density, or Demilec closed-cell where the attic is unvented.
