Insulation Company in Highgrove, CA
Blown in insulation is the most common fix we handle in Highgrove, because so many homes here were built between the 1950s and 1980s with insulation that has settled, thinned, or was barely adequate to begin with. When summer highs top 100°F and attics hit 150°F or more, an under-insulated ceiling becomes a hole in your cooling budget. Hometown Insulation Co carries eight insulation brands and installs blown in insulation, attic insulation, and spray foam, so the recommendation you get is matched to your home, not to whatever product we happen to have on the truck.

Why Highgrove Homes Are Different
Highgrove’s housing stock tells the story. This is not a tract of 2010s builds with code-minimum insulation already baked in. A large share of the homes we walk through in the 92313 ZIP code date from the Eisenhower through Reagan years, which means original fiberglass batts that have compressed over decades, or early cellulose that has settled into a thin, dusty layer. Many attics here measure R-11 or less. Current California Title 24 standards call for far more, and the gap between those two numbers is money leaving your house every summer.
The climate does not give these older homes any slack. Highgrove sits in a hot inland pocket where summer days regularly break 100°F. Attic temperatures climb past 150°F during heat waves, and that radiant heat pushes down through the ceiling all afternoon and evening. HVAC systems run nonstop, and rooms still feel uneven. We see the same pattern in older tract developments throughout 92313: minimal insulation, no radiant barrier, and cooling bills that make homeowners wince. The good news is this is a solvable problem, and it solves quickly once the right material goes in.
Our Main Highgrove Services
Two services account for most of the calls we take from Highgrove homeowners: attic insulation and spray foam. Here is what each one looks like here.
Attic Insulation in Highgrove
Attic insulation is the highest-ROI upgrade most Highgrove homeowners can make, because the heat load comes from above. We inspect what is already up there, remove or work around degraded material, and bring the attic to a level that actually resists that 150°F thermal assault. Many Highgrove attics need air sealing at the same time, since gaps around can lights, plumbing vents, and interior walls let conditioned air leak straight out. Get the full breakdown on Attic Insulation in Highgrove.
Spray Foam Insulation in Highgrove
Spray foam earns its keep in Highgrove when homeowners want air sealing and insulation in one pass. Closed-cell foam adds structural rigidity and blocks the air movement that fiberglass cannot, while open-cell foam is quieter and more forgiving in certain cavity applications. We install Icynene and Demilec spray foam, brands specified in high-performance building envelopes, not entry-level jobs. Older Highgrove homes with odd framing or tight access often benefit from foam where batts would leave gaps. See Spray Foam Insulation in Highgrove for specifics.

Blown In Insulation in Highgrove
Blown in insulation is the workhorse solution for Highgrove attics, especially in the 92313 ZIP code where older tract homes were built with a few inches of fiberglass or cellulose that has long since stopped doing its job. Our crews blow loose fill insulation across existing attic floors to bring R-values up to modern California standards without tearing out ceilings or disrupting the living space below. It is fast, it fills gaps that batts miss, and it starts paying for itself the first summer it faces a 100°F afternoon. For homeowners who want better comfort without a full renovation, Blown In Insulation is the service we recommend most often here.
Cellulose Insulation
Signs you need it
Your attic has old, settled cellulose that now looks like a thin mat instead of a fluffy layer, and upstairs rooms run noticeably hotter than the rest of the house.
What it costs in Highgrove
Blown cellulose for a typical Highgrove attic runs roughly $1.10 to $1.80 per square foot of attic floor, depending on depth and prep work.
How we do it
We prep the attic, seal bypasses, and blow GreenFiber cellulose to the target R-value using hoses run from the truck to the attic.
Blown In Attic Insulation
Signs you need it
Your home was built before 1980 and the attic still has original R-11 batts or less, leaving your air conditioner running constantly from May through October.
What it costs in Highgrove
Blown in attic insulation for a typical 1,200-square-foot Highgrove attic ranges from roughly $1,320 to $2,160, with larger or obstructed attics running higher.
How we do it
We remove or work around deteriorated old material, seal air leaks, and blow new insulation to an even depth across the entire attic floor.
What Blown In Insulation Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Blown cellulose per sq ft | $1.10 – $1.80 |
| Blown fiberglass per sq ft | $0.90 – $1.50 |
| Typical 1,200 sq ft attic | $1,320 – $2,160 |
| R-38 to R-49 upgrade (existing attic) | $1,500 – $2,800 |
Can you blow insulation over old material in Highgrove?
Yes, in most attics we blow new insulation directly over old, settled material after checking for moisture, rodent damage, and wiring issues. The old layer adds to the total R-value once the new material settles in, which keeps costs down.
How long does blown in insulation last in Highgrove’s heat?
Blown in insulation keeps performing for decades, but only if the attic stays dry and the material has not been compressed. Highgrove’s heat will not break down fiberglass or cellulose, though older homes with roof leaks need those fixed first. Call (877) 265-9918 for an attic evaluation.
Brands We Service in Highgrove
We install products from eight brands, including Icynene and Demilec spray foam, GreenFiber cellulose, and Owens Corning fiberglass. Parts for common Highgrove jobs are stocked locally, so most projects do not wait on shipping. See our brands for the full lineup.

— Daniel Lawson"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Steven Kim"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."
