Insulation Company in Highgrove, CA
Blown in insulation is the most common fix we handle in Highgrove, and it’s not close. The 92313 footprint is packed with mid-century ranch homes whose attic insulation has been settling for 40 or 50 years, and when summer heat pushes attic temperatures past 140°F, that thin R-11 layer stops doing much of anything. We’re Homeward Insulation Co, and insulation is all we do. If your Highgrove home runs its AC hard from June through September and upstairs rooms still feel warm by 4 p.m., call (855) 473-6516 for a free attic assessment.
Why Highgrove Homes Are Different
Highgrove sits in the hot, dry Inland Empire just east of Riverside, and the insulation problem here is almost never about keeping heat in. It’s about keeping radiant heat out. Summer attic temperatures in Highgrove routinely climb well past 140°F, and that heat doesn’t stay in the attic. It radiates down through the ceiling, forces your AC to work harder, and shows up on your August bill. Homes here were mostly built before modern Title 24 efficiency standards, so the original attic insulation was already undersized by today’s numbers before decades of settling made it worse.
The housing stock tells the same story. Highgrove is a small unincorporated Riverside County community, and most of the homes are older single-family ranch-style builds with standard vented attics. What we find when we open those attics is consistent: batts compressed to half their original thickness, bare decking where insulation has shifted, and gaps around can lights and vents that leak conditioned air straight into the attic. On especially hot stretches, our crews in Highgrove schedule attic work before dawn because working in a 140°F attic after 10 a.m. isn’t just uncomfortable, it’s unsafe. The good news is these homes respond fast to proper insulation. When you fix the attic, the whole house calms down.
Our Main Highgrove Services
Most Highgrove homeowners reach out about two things: upgrading attic insulation in an older ranch home, or sealing and insulating with spray foam in a renovation or addition. Both jobs are about managing the Inland Empire heat, but the right material differs by house.
Attic Insulation in Highgrove
Attic insulation is the biggest lever most Highgrove homeowners can pull on cooling costs. In a 1,400 to 1,800 square foot ranch built in the 1960s or 1970s, the attic is usually the single largest uninsulated surface in the house. We see attics where the original fiberglass batts are down to R-8 or worse after years of heat cycling and foot traffic from HVAC service calls. Upgrading the attic floor to R-38 or R-49 with a material matched to the home’s venting setup cuts afternoon heat transfer dramatically. Learn more about how we approach Attic Insulation in Highgrove.
Spray Foam Insulation in Highgrove
Spray foam does something fiberglass and cellulose can’t: it air-seals while it insulates. In Highgrove, that matters for homes with finished attics, bonus rooms, or ductwork running through unconditioned space. Open-cell foam on the roofline keeps heat out of the attic cavity entirely, which protects any HVAC equipment up there and stops dusty, hot air from circulating into the home. We work with both Icynene and Demilec, so the open-cell versus closed-cell decision is driven by the structure, not by what’s on the truck. See Spray Foam Insulation in Highgrove for the full picture.

Blown In Insulation in Highgrove
Blown in insulation is the workhorse solution for Highgrove’s older ranch homes. Most attics in the 92313 ZIP code were built with fiberglass batts that have settled, compressed, or been shoved aside during decades of rewiring and HVAC work. We blow in loose-fill insulation across the attic floor to build the R-value back up to Title 24 levels in a single day, and because we’re material-agnostic we choose between fiberglass and cellulose based on what your attic actually needs. Our crews know these mid-century vented attics well; we can usually tell you within minutes of opening the hatch whether you’re at R-11, R-19, or somewhere in between. The Blown In Insulation method also fills the gaps that batts leave behind, which is where most of the heat actually gets through.
Cellulose Insulation
Signs you need it
Your attic insulation looks dark, settled, or compacted, and your ceilings feel warm to the touch in the afternoon even with the AC running.
What it costs in Highgrove
Blown in cellulose for a typical Highgrove attic generally runs $1,500 to $2,800 depending on attic depth and access.
How we do it
We air-seal top plates and penetrations, then blow GreenFiber cellulose to an even R-38 or R-49 depth across the entire attic floor.
Blown In Attic Insulation
Signs you need it
Rooms at the back of the house or under a flat section of roof stay hot in summer, and you can feel heat radiating from the ceiling.
What it costs in Highgrove
Blown in attic insulation in Highgrove typically runs $1,200 to $2,500 for a standard attic, varying with square footage and target R-value.
How we do it
We check baffles and ventilation first, then blow loose-fill fiberglass or cellulose to a consistent depth, keeping eave vents clear as we go.
Blown In Fiberglass Insulation
Signs you need it
Your existing batts have gaps and voids, and you want a clean, lightweight fill that won’t hold moisture in a vented attic.
What it costs in Highgrove
Blown in fiberglass in Highgrove usually falls between $1,300 and $2,600, with final cost tied to attic square footage and depth.
How we do it
We run a hose up through the attic access, blow Owens Corning or Johns Manville loose-fill fiberglass to the specified R-value, and level it out.

Your attic has uneven insulation with bare patches, or you’re adding a room and need to top up existing loose fill quickly.
What it costs in Highgrove
Loose fill insulation for a Highgrove attic generally costs $1,200 to $2,400 depending on whether we’re topping up or starting fresh.
How we do it
We remove any wet or damaged material, check for air leaks, and blow new loose fill to a uniform depth with a calibrated hose.
What Blown In Insulation Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Cellulose attic blow-in (existing attic, R-38) | $1,500 – $2,800 |
| Fiberglass attic blow-in (existing attic, R-38) | $1,300 – $2,600 |
| Attic top-up over existing insulation | $1,200 – $2,400 |
How long does blown in insulation last in Highgrove’s heat?
Fiberglass loose fill lasts decades; cellulose settles about 20% and may need a top-up after 10 to 15 years. Highgrove’s extreme attic heat accelerates settling, so we slightly over-blow depth to compensate. Call (855) 473-6516 to have us measure your current R-value.
Is blown in insulation better than batts for old Highgrove attics?
Usually yes. Blown in fills around framing, wiring, and odd angles that batts can’t, and it’s faster to install in low-clearance ranch attics. The right choice still depends on your attic’s venting and condition, so we inspect before recommending.
Brands We Service in Highgrove

For Highgrove jobs we regularly install CertainTeed and Owens Corning fiberglass, GreenFiber cellulose, and Icynene or Demilec spray foam. See our brands for the full lineup.

FAQs About Insulation Company in Highgrove
Our crews work Highgrove attics before dawn during heat waves, usually starting by 5:30 or 6 a.m. and finishing before the attic becomes unsafe to work in. Most assessments happen within a day or two of your call, and we can often schedule the job within the same week.
Most insulation-only jobs don’t require a permit in unincorporated Riverside County, but if your project involves structural changes or spray foam on a roofline, the rules can shift. We handle the paperwork when it’s needed, and we’ll tell you upfront if your job crosses that line.
Often, yes. If the old material is dry, mold-free, and not blocking ventilation, we can blow new loose fill directly over it. If it’s wet, rodent-damaged, or packed down to nothing, removal is the better path. We’ll show you what we see before we start. Call (855) 473-6516 for a free estimate.
