About our insulation contractor team in Cerritos
Caliber Cerritos Spray Foam Insulation is an insulation contractor in Cerritos, CA. I started it in 2021 after years as a heating and air tech. We're best known for attic sealing and insulation done in a sensible order, for homeowners and some property managers in Cerritos and the cities around it.

Why a heating and air tech started insulating attics
I spent years as a heating and air tech, and most of that work put me in attics. Over and over I found good equipment working hard under insulation that was thin, crushed or missing. So in 2021 I switched trades and started Caliber Cerritos Spray Foam Insulation here in Cerritos.
What I care about most is doing things in the right order. New insulation over air leaks, damp wood or a furnace that isn't venting right just hides the trouble. I'd rather tell you what needs fixing first than sell you a job that looks nice and doesn't help.
Most of our calls come from homeowners in Cerritos and the cities around it about a drafty room, a hot upstairs or the room over the garage. Some come from property managers with commercial buildings. Whatever brought you to our home page, I want the numbers on your estimate to match the house you actually have.
What you can expect when we're in your attic
These are the things you'll notice when we work on your house. Each one comes from my years in other people's attics and from wanting the job to actually help.
Your attic seen as one system
Because I came from heating and air, I look at your attic as one system. We check the ducts and the equipment along with the insulation, since a leaky duct or a struggling unit up there changes what the right fix is.
Estimates from your own measurements
Your estimate is written from measurements taken in your own attic or crawl space, starting with how many inches of insulation are already up there. That way you can set it next to any other bid and compare the two line by line.
What we find, told first
We tell you plainly what we find before anyone talks about new insulation, even when the problem belongs to another trade. If old material is soaked or full of droppings, or a vent is buried, you'll hear about it, because covering it over only hides it.
The owner checks the work
I do the site visits and write the estimates myself, so you're never sitting across from a salesperson. Our installers do the work, and I check it before we call the job finished. That way the person who looked at your house is the one who signs off.
Licensing for insulation work in California
In California, anyone who builds or alters a structure needs a license from the state licensing board when the job needs a building permit, uses employees, or comes to $1,000 or more in labor and materials. We're fully licensed and insured.

What happens after you call us
From your first call to the final check, here's how a job goes with us. The order stays the same whether it's the attic of a house or a commercial building.

I come out and measure
I come to your home or building myself for a free estimate with no obligation. I go up into the attic or crawl space, measure what's there and look at the ducts and equipment. I also note anything that needs fixing before insulation goes in.
Your written estimate, in order
You get the estimate in writing, with each step listed in order. Before we set a start date, we check with your city about approvals and permits, since Cerritos wants Planning approval before any home improvement work begins. When a job needs a permit, we handle the paperwork and the inspection.
Installers work, I check
Our installers do the work your estimate lists, in that order, and clean up as they go. Before we call it finished, I go up and check the job myself and walk you through what was done. Satisfaction guaranteed.
