Insulation Company in Somis, CA
Somis is a quiet, agricultural pocket of Ventura County where homes sit on generous lots, many built between the 1960s and 1990s with original insulation that’s long since settled or been chewed through by roof rats drawn to the surrounding avocado and citrus orchards. We’re Thistledown Attic Insulation, and we handle attic and spray foam insulation for Somis homeowners who want a crew that shows up with a written price, lays down drop cloths, and treats the house like people live in it, because they do. Every job is backed by our 365-Day Done Right Promise. Call (341) 217-4867 and a real person answers, day or night.
Why Somis Homes Are Different
Somis sits in a transitional zone between the coastal cool of Camarillo and the hotter inland valleys, so insulation here has to handle both directions: blocking daytime heat gain during summer afternoons and holding warmth during cool marine-layer nights. The daily temperature swing is real, and a one-size-fits-all R-value guess doesn’t address it. Homes here are mostly single-family detached with wood-frame construction and stucco exteriors, often on larger rural or semi-rural lots with agricultural outbuildings. That means attics over living space, plus converted barns, workshops, and detached structures that need their own insulation strategy.
We see two recurring issues in Somis more than almost anywhere else we work. First, original fiberglass batts from the 1960s through 1990s have settled, compressed, or been torn apart by rodents. Second, roof rats love the avocado and citrus trees that surround so many Somis properties, and they find their way into attics, leaving behind damaged insulation and droppings that require full removal and re-insulation. Moisture is also a factor: cool, damp marine-layer mornings can create condensation risk in under-insulated attics, so material choice matters. We match the product to the attic, not the other way around.
Our Main Somis Services
Two jobs dominate the calls we get from Somis homeowners: attic insulation upgrades in older ranch-style houses, and spray foam for converted agricultural structures and hard-to-reach spaces. Each has its own dedicated page with local pricing and specifics.
Attic Insulation in Somis
Most Somis attics still have the original fiberglass batts installed when the house was built, and decades of settling plus rodent activity mean they’re no longer doing their job. We remove damaged material, air-seal the attic floor where it makes sense, and install fresh insulation from brands like Owens Corning, CertainTeed, and Rockwool. We check for evidence of roof rat entry and point you to what the insulation can and can’t fix. Attic Insulation in Somis covers everything about this service in detail, including what to expect during the job and what it costs.
Spray Foam Insulation in Somis
Converted barns, workshops, and additions on Somis properties often have odd angles, exposed framing, and air leaks that batts simply cannot seal. Spray foam handles those spaces by expanding into gaps and creating an air barrier, which also helps with the condensation risk during foggy marine-layer periods. We install open-cell and closed-cell foam from Icynene and Demilec, depending on the space and the moisture conditions. Spray Foam Insulation in Somis explains the difference between foam types and when each one makes sense for your structure.

FAQs About Insulation Company in Somis
Most Somis jobs are scheduled within 3 to 5 business days. Emergency situations, like a rodent-damaged attic that has exposed wiring, can often be seen same-day. Call (341) 217-4867 and a live person will give you a straight answer on timing.
Most attic insulation and air sealing work does not require a permit in unincorporated Ventura County. If your project involves spray foam in a converted structure or involves structural changes, we’ll tell you upfront whether permit coordination is needed and what that looks like. You’ll know before you sign anything.
Yes. Many Somis properties have barns, workshops, or converted ag structures, and those spaces need different insulation approaches than a standard attic. We’ll assess the structure, the moisture conditions, and how the space is used, then recommend materials that fit. That recommendation comes in writing with your price.
