What Thousand Oaks Homeowners Say About Aspen Attic Insulation Thousand Oaks
Reviews matter in Thousand Oaks because attic work is invisible until it isn’t. You can’t see the gaps that leak conditioned air into the Conejo Valley heat, and you can’t easily verify whether the insulation under your feet was installed correctly. What our customers tell us, and what we hear repeated on calls from Newbury Park to Wildwood, is that the difference comes down to knowing who’s walking through the door and what the job costs before it starts. That’s the standard we’ve held since 2002.
Recent Reviews
Our upstairs bedrooms were running 12 degrees warmer than downstairs all summer. Garrett’s crew found gaps around the can lights and a section of original blown-in that had settled to almost nothing. They air-sealed the penetrations, added Owens Corning blown-in insulation to R-38, and the temperature difference is down to about 3 degrees now. The written price matched the final bill to the penny.

I called at 9pm on a Sunday because I’d just discovered raccoons had torn through the old fiberglass batts above the garage. A live person answered, which surprised me. They sent a tech named Luis the next morning, photo and name texted to me before he arrived, just like the website said. He removed the contaminated material and installed new Johns Manville batts the same day. The 365-day written guarantee was included without me having to ask.

Three companies quoted our attic. Aspen was the only one that sent a written price before scheduling anything. The other two gave me a number over the phone and said ‘plus whatever we find.’ Garrett explained that blown-in insulation, loose fibers blown into the attic cavity to fill every gap, would work better for our low-slope roof than trying to wedge batts in. He was right. The house holds temperature noticeably better, and our gas bill dropped about 18 percent last winter.

We had spray foam insulation installed in the attic of our 1960s ranch in the Conejo Valley. The technician who did the work, his name was Marco, wore a clean uniform and showed me his photo ID at the door before he touched anything. He walked me through why Icynene open-cell made sense for our roof assembly, and he was right about the sound dampening too. You don’t hear the Santa Ana winds howling through the attic anymore.

What sold me was the Done Right Promise. I’ve had insulation work done before where the contractor vanished the second the check cleared. Garrett put it in writing that if anything fails within 365 days, covering labor and materials, they come back free. We had one small issue with a baffle that came loose six months later, and a tech was out within two days to fix it. No pushback, no invoice. That’s what the guarantee actually means.

We found Aspen through a neighbor who’d used them for an attic insulation upgrade. The difference was obvious from the first call: the person who answered could actually discuss R-values and ventilation without putting me on hold to ‘check with a manager.’ They used Rockwool batts in our attic and the result in the upstairs hallway is dramatic. The written price, the background-checked tech, the photo texted ahead of time. Everything they said would happen, happened.

Why Customers Trust Us
The reviews above share a pattern because the work follows a pattern. Every technician who walks into a Thousand Oaks home is background-checked, identity-verified, and arrives in a marked uniform with a photo ID badge at the door. The tech’s name and photo are sent to the homeowner before the visit, and if anyone else arrives, the visit is free and we make it right. That’s the Threshold Standard, and we’ve operated to it since 2002. Every job carries a written price before work starts, with no post-job surprises, and every job carries the 365-Day Done Right Promise in writing, covering labor and materials, with a free second visit if a repair fails. We stock materials from eight premium brands, Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so the right product goes in for your attic, not just whatever is on the truck. Garrett Sloane, Owner, answers for every job personally, and a live person answers the phone 24/7, no voicemail loops. If your attic is underperforming, call (805) 309-1610 for a straight answer and a written price.
