Insulation Company in Ashland, CA
Thistledown Attic Insulation is the insulation company Ashland homeowners call when they want the number in writing before any work starts. Ashland’s older East Bay homes, many built between the 1920s and 1970s, tend to have thin or missing insulation and a damp, coastal-influenced climate that makes air sealing just as important as thermal protection. We install attic insulation and spray foam insulation with the same Cedarwell Care Promise on every job: shoe covers at the door, drop cloths across your hallway, and a photo of the clean-up before we leave. Call (341) 247-0222 for a free estimate.
Why Ashland Homes Are Different
Ashland sits in the cooler, fog-influenced corner of the East Bay, where mornings roll in damp from San Francisco Bay and winter temperatures stay mild but persistently moist. That means the insulation problems we see here are rarely about deep freezes. They are about cool, damp air sneaking into under-insulated attics and walls, condensing against framing, and making bedrooms feel chilly on a 55-degree foggy morning. Many Ashland homes are wood-frame bungalows, ranch-style, and split-levels from the 1920s through the 1960s with original minimal insulation, if they have any at all. Recessed can lights and older wiring are common, and both complicate retrofit work in ways a generic insulation crew misses. The homes here need vapor management and air sealing as much as they need more R-value.
Our Main Ashland Services
Most Ashland homeowners reach out to us for one of two jobs. Each has its own page with pricing, what to expect, and answers to the questions we hear most in this area.
Attic Insulation in Ashland
Attic insulation in Ashland is usually a retrofit job on a home that has some insulation, just not nearly enough. We commonly find three to four inches of settled fiberglass under rafters, which leaves the whole house feeling damp-cool all winter. Blown-in insulation from CertainTeed or GreenFiber, for instance, fills the gaps the old batts leave behind, including around can lights where we install protective dams first. In Ashland’s split-levels, the attic access is often in a hallway ceiling, and that hatch itself is a major air leak if it is not sealed and insulated. See the full scope on our Attic Insulation in Ashland page.
Spray Foam Insulation in Ashland
Spray foam in Ashland works where moisture is the main concern, because closed-cell foam from Icynene or Demilec also acts as an air and vapor barrier. That matters in this climate, where morning fog works its way through tiny gaps in rim joists and top plates and condenses inside wall cavities. Homeowners here often notice a draft and a faint musty smell in the room above the garage before they see anything else. We apply foam to the right thickness for the space, and we choose pet-safe product lines where the option exists so the dog can stay home while we work. Details are on the Spray Foam Insulation in Ashland page.

What pushes the price up in Ashland is usually access: a tight attic hatch, recessed can lights that need protective dams, or old knob-and-tube remnants that need an electrician to sign off before insulation touches the area. Every job gets a written price before any work starts, always. That number comes from a technician actually looking at your attic, not a range on the phone.

Yes, and we treat those homes with extra care. Older wiring, especially knob-and-tube remnants, needs to be evaluated before insulation touches it, and we coordinate with a licensed electrician when that is required. We will tell you exactly what we find before we recommend anything.

What Ashland Customers Say
"Spray foam in the garage and new attic insulation. Considerate, calm crew that protected the floors and kept the dust down with our little ones around. Explained it all patiently."
- Hassan Qureshi"Attic insulation. The crew laid down protection from the front door to the attic hatch and vacuumed up every bit of the old material. House holds its warmth now and there was zero mess."
- Rowena Platt"Careful and clean from start to finish. They covered the hallway, wore booties, and hauled off all the old material without leaving a speck. Respectful of the home the whole time."
