About our insulation contractor company in Gilroy

How I got into insulation
I spent years running the schedule for a busy company, lining up crews and jobs, and I learned insulation working right alongside the installers on the jobs I booked. In 2021 I started this business here in Gilroy so I could do the work and still keep each job running in the right order. That order matters to me, because insulation laid over a leak or an old wiring problem just hides it until it gets worse.
Most people call me because the upstairs runs hot, the floors are cold, or they just bought an older place and have no idea what's in the attic. Termites are a real worry around Gilroy, so I check the wood in your attic or crawl space before anything new goes over it. Property managers call us about commercial buildings too, and you can see everything we do on our home page.

What working with us is like
Your job runs in the right order
New insulation over old material that's soaked or full of droppings just keeps the problem, so we plan any repairs, removal and air sealing, which is closing the gaps around pipes, lights and the hatch, before anything new goes in. Each step happens when it should, and you'll know which one comes next.
You talk with the owner
From your first call through the estimate you're talking with me, so the person answering your questions is the one planning your job. Our installers do the work, and I check in along the way and go over the finished job with you.
You hear what we find right away
I look over your attic, crawl space or walls in person before I price anything, so the estimate fits your house and not a guess. If I find old wiring, damp spots or insulation that looks like vermiculite, I tell you then so you can plan for it.
Licensing, insurance and permits
Gilroy city business license
The City of Gilroy requires every business that works in the city to hold a city business license, even one based somewhere else. That makes it a fair thing to ask any contractor before they start on your house.
Licensed and insured
We're licensed and insured, and our work is backed by our satisfaction guarantee. If your job needs a permit, we pull it and set up the inspections with the city or county office, and we'll talk it through with you at the estimate.
