Insulation contractor services in Cerritos, CA

Caliber Cerritos Spray Foam Insulation is an insulation contractor in Cerritos, CA, and our 16 services cover attics, walls, crawl spaces and commercial buildings. Most calls start with a hot upstairs, a drafty room or a power bill that keeps climbing, and the fix is usually sealing the leaks and getting the right amount of insulation in the right places. The price turns on the size of the space, how many inches are already up there, whether old material has to come out and whether foam or loose fill fits your house. The schedule turns on removal and any city approval your job needs first. Your written estimate lists each step in order.

  • Spray foam insulation

    Spray foam swells to fill the gaps it touches, so it insulates and seals air in one pass. It suits rooflines and odd-shaped spaces where loose fill won't stay in place.

  • Attic insulation

    Upstairs rooms running hot? We seal the attic floor first, then add insulation to an even depth, keeping it full out at the edges where coverage usually runs thin.

  • Blown-in insulation

    Blown-in insulation is loose fill blown through a hose, the usual way to top up an attic that's thin. We seal the gaps first so the new layer isn't fighting a draft.

  • Home insulation

    What does insulating a whole house involve? We go through the attic, walls and crawl space, find where the heat gets in and out, and list the work in a sensible order.

  • Insulation removal

    Old insulation that got soaked or filled with droppings has to come out, because new material laid on top just keeps the problem. We bag it, clean the attic floor and start fresh.

  • Crawl space insulation

    Cold floors over a crawl space usually mean the underside of the house is bare or the old insulation has dropped. We insulate between the floor joists so the rooms above stay warmer.

  • Wall insulation

    We insulate exterior walls in finished homes through small holes we patch afterward, and in open walls during a remodel. It's for rooms that feel drafty even with the windows shut.

  • Air sealing services

    Air sealing means closing the gaps where house air leaks into the attic or walls before any insulation goes in. It's the step that stops drafts, and the one that gets skipped most.

  • Basement insulation

    For a home or building with a basement, we insulate the walls and the rim along the top, where the house meets the foundation, so the space below holds steadier temperatures.

  • Closed-cell foam insulation

    Closed-cell foam is dense foam that blocks moisture as well as heat. We use it where water or damp air is the worry, like a crawl space or the underside of a roof deck.

    Explore service

  • Open-cell foam insulation

    Open-cell foam is the lighter, softer foam, and it fills cavities and seals air for less than closed-cell. We spray it in walls and rooflines where moisture isn't the concern.

  • Commercial insulation

    Manage an office or shop building? We insulate and air-seal commercial spaces too, with the same walkthrough, measurements and written, step-by-step estimate we give homeowners.

  • Crawl space vapor barrier

    A crawl space vapor barrier is heavy plastic sheeting laid over the dirt so ground moisture stays out of the wood above. We lap and seal the seams so it doesn't shift.

    Explore service

  • Vapor barrier installation

    Where does a vapor barrier go? It depends on the wall, ceiling or floor and how the house is built, so we look before we install one rather than adding plastic by habit.

  • Attic air sealing

    Attic air sealing is what we're best known for. We close the gaps around can lights, pipes, wires and the hatch, so the insulation on top can do its job.

  • Retrofit insulation

    Retrofit insulation means adding to a house that's already built and lived in, often an older one with thin or patchy coverage. We work around finished rooms, wiring and ductwork.

Why we look at the whole attic, not just insulation

Insulation is only part of what's in your attic, and the ducts, vents and equipment share that space. We look at all of it and tell you what we find before we talk about new material.

We check the ducts along with the insulation

Your attic usually holds more than insulation. The ducts and often the equipment live up there too, and they work as one system with it. So when I go up, I look at the ducts and the equipment along with the insulation, and I tell you plainly what I find, even when it's a problem that belongs to another trade.

Order matters just as much. New insulation over air leaks, damp wood or a furnace that isn't venting right just hides the trouble, so the fix comes first. Then we seal the air leaks and keep the eave vents clear so the attic can still breathe. I'd rather tell you what needs doing first than sell you a job that looks nice and doesn't help.

  • Estimates measured in your attic

    Your estimate is written from measurements taken in your own attic or crawl space, so the numbers match the house you actually have. Each step is listed in the order we'd do it, so you can put it next to any other bid and compare line by line.

  • No salesperson, just the owner

    The person at your door is me, not a salesperson. Because I'm the one who crawled through your attic and took the measurements, I can answer questions about the estimate and explain why one step comes before another.

  • City approvals checked before we start

    In Cerritos, the city's Planning Division has to approve a home improvement project before work begins, and Building & Safety issues the permits. Before we set a start date, we check with your city, and when a job needs a permit, we handle the paperwork and the inspection.

  • Foam only where it pays

    Foam costs more and seals air while it insulates. For most attics, sealing the gaps and topping up loose fill usually wins, unless your ductwork runs through there, and we'll tell you which one fits your house and why.

What happens after you call or send a message

Our jobs run through the same four steps, from your first call to the walkthrough at the end. Here's what you can expect, and who you'll deal with at each one.

  1. Call or send a message

    Call us at (562) 307-9067 or fill out the form on our contact page, and tell us what's going on, like a hot upstairs, cold floors or a power bill that keeps climbing. We reply within one business day to set up a visit at a time that works for you.

  2. I come out and measure

    I come out myself and go through your attic, walls or crawl space. I measure, note how many inches are already up there and take photos of what I find. Then you get a free written estimate that lists each step in the order we'd do it, with no obligation.

  3. Our installers do the work

    Once you say go and any city approval is in place, our installers come out on the day we set. They cover floors and the path to the attic before they start, then seal, clear out or insulate in the order your estimate lists.

  4. We go over the finished job

    When the installers finish, I check the work before we call it done. Then I go over it with you, show you what was sealed and how deep the new insulation sits, using photos where the space is tight, and answer anything you still want to know.

Who's behind Caliber Cerritos Spray Foam Insulation

So I switched trades and started fixing the part nobody was looking at.

We're fully licensed and insured, and we're best known for attic sealing and insulation done in a sensible order. Homeowners in Cerritos and the cities around it call us, and so do some property managers with commercial buildings. You can read more about how we work on our about page.

Questions about insulation estimates and the work

These are the questions we hear most when someone calls about an attic, a drafty room or a crawl space. The answers come from how we work and from the city's own rules.

How much does insulation cost in Cerritos, CA?

It depends on what's in your attic or crawl space, so we don't quote a price over the phone. The biggest swings come from old material that has to come out first, how many gaps need sealing and whether foam makes sense because your ductwork runs up there. Your written estimate breaks each of those out, so you can see where the money goes.

How do I get my house ready for attic insulation?

Clear a path to the attic hatch and move whatever's stored right under it, so the crew isn't carrying hoses and bags around your things. If boxes are stored up in the attic, those usually need to come down too, since we can't seal or insulate under them.

Do I have to leave the house during spray foam insulation?

Usually yes for spray foam, and the foam maker's instructions set the re-entry time, the hours before you, the kids and the pets can come back inside. We'll go over that wait with you before the job day. Blown-in insulation and air sealing usually don't send anyone out of the house.

Should old attic insulation be removed before adding new insulation?

Only when it's soaked or full of droppings, because new insulation laid on top keeps that problem in the attic. Dry, clean insulation can usually stay, and we add to it once the air leaks under it are sealed.

What hours can insulation crews work in Cerritos?

Cerritos allows construction work Monday through Friday from 7 a.m. to 6 p.m. and Saturday from 10 a.m. to 5 p.m. None is allowed on Sundays or city holidays unless the city approves otherwise in writing, so job days get booked inside those hours.

How do I compare insulation bids from different contractors?

Lay them side by side and check that each one is based on measurements taken in your house and lists the same steps, like air sealing, removal, the depth of new insulation and clear eave vents. Also check licensing, because the California Contractors State License Board requires a state license when a project needs a building permit, uses employee labor or totals $1,000 or more in labor and materials. Cerritos also requires contractors working in the city to hold a city business license.
