Spray foam insulation
Foam seals air while it insulates, but it costs more. For most attics here I'd seal the gaps and top up loose fill instead, unless your ductwork runs up there, where foam usually earns its price.
B&J Pico Rivera Insulation Company is an insulation contractor working in West Whittier-Los Nietos, CA. We seal the gaps, clear out bad old insulation and add new where your attic, walls or crawl space need it.

West Whittier-Los Nietos sits right next to Pico Rivera, where we're based, and we do the same work across the line in Whittier. It's unincorporated county land, so there's no city hall here, and the county is the building office I check with before a job starts. Most houses are lived in by their owners, with a fair share of rentals mixed in, so we hear from homeowners and from landlords who want a problem found before the next tenant moves in.
Many attics we open here still have thin, packed-down insulation, and sometimes it's wet from an old roof leak or full of droppings. The price turns on how much area we're covering, whether that old material has to come out, how many gaps need sealing and whether you go with foam or loose fill. The schedule turns on the same things, plus any roof or wiring repair that should come first and any permit the county requires. I'll give you your own figure in a written estimate after I've seen the job.
I measure how many inches are already up there and photograph what I find, like wet spots, droppings and old wiring, so you see your own attic before I quote anything.
If the roof leaks or old wiring needs attention, I'll tell you to fix that first, because new insulation laid over it only hides the problem until it shows up somewhere worse.
Our crew keeps insulation full out to the edges, where it's usually thinnest, and keeps the eave vents clear so the attic can breathe and moisture doesn't build up in the framing.
Foam seals air while it insulates, but it costs more. For most attics here I'd seal the gaps and top up loose fill instead, unless your ductwork runs up there, where foam usually earns its price.
Most calls here start in the attic, where older houses often have a thin, packed-down layer. We measure what's there, deal with anything spoiled or leaking, seal the gaps and then add to it.
Blown-in insulation is loose fill blown through a hose, and it's how we top up most attics. It settles into corners and around framing that batts can't reach, and it goes in with little mess.
When the whole house feels drafty or the power bill keeps climbing, we look at the attic, walls and floors together, then tell you which one is worth doing first and why.
If old insulation is wet, matted or full of droppings, it comes out before anything new goes in, because new material over it keeps the problem. We bag it and keep the dust out of your rooms.
For raised-floor houses with cold floors, we insulate under the floor from the crawl space. We check for dampness and leaking pipes first, since insulation held against wet wood won't stay put or do much.
Older walls are often empty inside. We fill them through small holes, from outside or in, and patch them afterward, so your walls get insulated without tearing out drywall or stucco.
Air sealing means closing the gaps before insulating. Besides the attic, we find leaks around doors, plumbing runs and the room over the garage, so new insulation isn't fighting a draft.
Where a house has a basement, we insulate its walls with material that handles damp, since concrete against soil holds moisture, and we check for leaks before covering anything up.
Closed-cell foam is dense foam that blocks moisture as well as heat. It's the one we reach for where damp is the issue, like a crawl space wall or under a floor close to the ground.
Open-cell foam is lighter and softer, and it fills odd-shaped spaces and quiets noise well. It suits a roof deck or interior walls where moisture isn't the worry, and it costs less than closed-cell.
We also insulate small shops, offices and rental buildings. For landlords and property managers, we work around tenants and give you photos of what we found, so you have a record for later.
A vapor barrier is a sheet laid over the dirt in the crawl space to keep ground moisture from rising into the floor. We overlap and seal the seams so damp can't sneak up between them.
In walls and floors that see moisture, a vapor barrier has to go on the correct side of the insulation. On the wrong side it can trap water in the framing, so we check before installing.
Before we add insulation up top, we seal around can lights, the attic hatch, pipes and wire holes, because loose fill can't stop air moving through a gap and the room below stays drafty.
Retrofit insulation is adding to a house that's already finished and lived in. We work through the attic, crawl space and small wall openings, and clean up as we go so you can stay comfortable.
Send the form and we'll get back to you within one business day to set a time. I come out, look at the job and give you a written estimate with photos, free and with no obligation.
I look at the attic, crawl space and walls myself and write the estimate, so the person explaining your house to you is the one who actually saw it.
Our installers do the work and keep it tidy, since you're living there while they're up in the attic. I go over the finished job with you before we call it done.
We're fully licensed and insured, and our work is satisfaction guaranteed. Ask me anything about the estimate before you decide, because it's your house and the choice should be yours.
Here's what homeowners here ask most about permits, licenses and inspections before they hire an insulation contractor.
LA County Public Works decides, because it issues permits for unincorporated county property like this, covering alterations, repairs and replacements. Its permit list doesn't name insulation on its own, so before work starts we check with the county, and if your job calls for a permit, we handle the paperwork and the inspections.
Fixing a roof is on the list of work the county issues permits for, so check with the county before the repair starts. I'd want that leak fixed before any insulation goes in, since new material over a wet spot just hides the damage. If I find one during the estimate, I'll show you in the photos.
A contractor needs a license from the California Contractors State License Board when the job needs a building permit, uses employees, or costs $1,000 or more in labor and materials, counted across all the contracts on the project. That's worth asking about before anyone starts work on your house. We're fully licensed and insured.
The first inspection has to be requested within 12 months of the county issuing the permit, and follow-up inspections are scheduled every 6 months after that to keep the permit active. When our job needs a permit, we handle the inspections, so you're not the one keeping track of those dates.
