Insulation Company in Madera, CA
Madera sits flat on the San Joaquin Valley floor, where July and August highs routinely push past 108°F and attics bake well above 150°F. Most of the homes here were built between the 1950s and 1970s as modest agricultural-workforce housing, and many left the builder with barely 2 to 3 inches of settled attic fiberglass, or none at all in the walls. That combination makes attic insulation in Madera one of the highest-ROI home improvements you can make anywhere in California. We’re Woolsey Attic Insulation, and we handle two things: attic insulation and spray foam insulation. Both come with a written price before we touch anything, a live person on the phone 24/7, and a 365-day written guarantee. Call (325) 240-5411 any time.
Why Madera Homes Are Different
Madera’s older housing stock was built fast and cheap to house farm workers and packing-house employees. In the neighborhoods north and west of downtown, slab-on-grade homes from the 1950s and 60s often went up with zero wall insulation and the bare minimum in the attic. A dark-tile roof, a 150°F attic, and uninsulated 2×4 walls can push August cooling bills past $400 a month even for a small house. We see it constantly. The newer subdivisions that spread toward the Highway 99 corridor in the 1990s and 2000s used standard tract construction, but many still fall short of current Title 24 attic R-value requirements. What really sets Madera apart is the fog season. From December through February, dense tule fog rolls in and lingers, pulling attic temperatures down and introducing sustained moisture that degrades old fiberglass batts. Insulation here has to work hard in both directions: blocking brutal summer heat gain and managing winter moisture. That’s the exact thing we design every Madera job around.
Our Main Madera Services
Madera homeowners call us about two things most often. Here is what each involves here, with a link to the full page for that service.
Attic Insulation in Madera
Older Madera homes typically settled with 2 to 3 inches of loose fiberglass that has compressed, shifted, and stopped doing its job. We blow in fresh insulation on top or remove and replace it entirely, bringing the attic up to a proper R-value for the Central Valley’s heat load. On slab-on-grade homes west of downtown, we often recommend wall insulation in addition to the attic, because those 2×4 cavities were built empty. Lowering the attic temperature on a 150°F day is the single fastest way to cut cooling cost here. Read the full breakdown on our Attic Insulation in Madera page.
Spray Foam Insulation in Madera
Spray foam is a two-part liquid that expands on contact and seals gaps airtight. In Madera it matters because many older homes have open, poorly sealed attic planes that pull superheated air down into the living space all afternoon. Tule-fog winters add a second job for foam: sealing against the moisture that makes existing fiberglass damp and ineffective. We work with open-cell and closed-cell systems depending on the roof assembly, and the recommendation fits the house, not whatever happens to be on the truck. See Spray Foam Insulation in Madera for specifics.

Pricing for Insulation Company in Madera, CA
| Service | Typical range in Madera |
|---|---|
| Attic insulation, basic blow-in (small attic) | $300 – $600 |
| Attic insulation, standard blow-in (up to 1,200 sq ft attic) | $700 – $1,200 |
| Attic insulation, larger attic (1,200 – 2,000 sq ft) | $1,200 – $1,700 |

| Wall injection insulation (retrofit, older Madera homes) | $800 – $2,500 |
What pushes a Madera job higher is usually the condition of the existing attic: compressed, dusty old fiberglass that has to be removed first costs more than simply blowing fresh insulation on top. Slab-on-grade homes with no wall insulation can also add a separate wall-injection scope. Whatever the number turns out to be, you get the exact written price before any work starts, and that number does not move.

What Madera Customers Say
"Insulation job was done well. Scheduling took a little longer than I'd have liked, they were booked out a couple weeks. But once they came it was quick and the house is cozier."
- Felicia Grant"The guy didn't try to sell me on foaming the whole house. He said the attic was where I'd actually feel it and left it at that. Honest, and he was right, our bills dropped."
- Angela Ruiz"Drafty old house that never felt comfortable. After the attic and some air sealing it's a different place. On time, clean, and the quote didn't change. Wish I'd done it years ago."
