Serving Hollister, CA and surrounding areas. (831) 271-0020
Hollister Insulation was founded in 2025 right here in Hollister, California. We started this business because we kept hearing the same story from neighbors: high energy bills, uncomfortable rooms, and contractors who either never showed up or left without explaining what they did. We knew there was a better way.
Hollister is a real community. Most people here own their homes, plan to stay for years, and care about keeping their properties in good shape. The housing stock ranges from older homes near downtown to newer subdivisions on the east side - and every one of them has its own insulation needs. We have worked on all of them.
We are not a franchise or a call center. When you call us, you talk to someone who actually works here. We know the local housing stock, we know the climate - those hot San Benito Valley summers and cool winters - and we know the problems that come with living in this area. That local knowledge changes how we approach every job.
We serve 12 communities across Central California, from Hollister and Gilroy to Salinas and Santa Cruz. Every job gets the same attention, whether it is a single-room upgrade or a full home insulation project.
Every job starts with proper prep - protective gear, drop cloths, and a clear plan. Your home is treated with the same care we would give our own.
We tell you what we found, what we recommend, and what it will cost before we start. No surprises on your invoice when the job is done.
We follow California energy code requirements and pull permits when needed. You get documentation you can use when you sell your home.
A lot of Hollister homeowners commute. We schedule around your availability and keep you updated throughout the job so you are never left guessing.
