Cold floors in older houses
Older houses around Pico Rivera often have thin, patchy or missing insulation under the floor, so the rooms over the crawl space stay cold underfoot even with the heat running.
Cold floors and drafts often come from underneath. We check the framing and moisture first, then fit insulation snug against the floor above.

At B&J Pico Rivera Insulation Company, crawl space insulation means fitting insulation to the underside of your floor in Pico Rivera, pressed tight against the air barrier that keeps your house's air apart from the space below. Done right, the rooms above stop losing heat through the floor and feel warmer underfoot.
Most calls start with something you feel, like a cold floor in a back bedroom or a draft at the baseboards, and the cause is usually under the house where nobody's looked in years. Building permits in Pico Rivera come from the city's Building Division, and its list is written around heating and cooling changes and most wiring or plumbing work, so instead of guessing, we check with the building office that covers your address before we start and handle the paperwork and inspections if your job calls for a permit.
The price moves with the size of the crawl space, how easy it is to get in, which material you choose and whether old insulation or damaged framing has to be dealt with first. The schedule turns mostly on that last part and on any permit, because repairs always come before insulation. When I come out, you get a written estimate with photos of what I found, so your number is based on your house and not a guess.
I'd rather you understand your own crawl space than take my word for it, so I walk you through what's down there in plain words before we ever talk price.
If there's a plumbing leak or old wiring under the floor, I'll tell you to fix that first, because new insulation over it just hides the problem until it's bigger.
I started this business in Pico Rivera in 2020 after years doing upkeep under rental houses, and we work in many of the cities around it, like Downey and Whittier.
Under the floor, the first thing I look at is the framing, because rot or other damage turns an insulation job into a repair job. National guidance agrees that repairs come before insulation, so if I find a problem you'll see it in the photos and we deal with it first.
We also talk about the vents before anyone touches them. Closing crawl space vents by themselves can trap moisture under the house, and national guidance warns that with a furnace or water heater down there that burns fuel and vents on its own draft, it can turn deadly. If you want a sealed crawl space, we plan the whole space first, not just the vent covers.
Once the framing is sound and the vents are settled, our installers fit the insulation snug against the underside of the floor, with no gaps, crushed spots or empty pockets, and carry it all the way to the edges where it's easy to come up short. I go over it with you before we call it done. If drafts are also coming through the walls or around pipes and doors upstairs, we can look at wall insulation or air sealing on the same visit.
Older houses around Pico Rivera often have thin, patchy or missing insulation under the floor, so the rooms over the crawl space stay cold underfoot even with the heat running.
Batts that dropped, sagged or soaked up a leak don't slow much heat, and new insulation over them keeps the problem, so we look at what should come out first.
Landlords and property managers call us when a unit sits empty, because that's the easiest time to get under the floor and find what's been covered up before the next tenant moves in.
If the heat runs long in winter, some of what you're paying for can be going straight down through a bare floor, and that's one of the first things I check.
Send the form and we'll get back to you within one business day to set a time. I'll come out, look under the house and write you a free estimate with photos, and there's no obligation.
I'm the one who comes out to look under your house and write the estimate, so the person who saw your framing is the one explaining it to you.
Once you say go, our installers do the work, and I go over the finished job with you before we call it done, so nothing is left unexplained.
We take calls seven days a week, from 7 AM to 11 PM, so you can call after work or on a weekend to set up the visit.
These photos show the kinds of floor insulation, ground covers and hatch setups we can talk through when I'm out at your house.
Here's what Pico Rivera homeowners usually ask before they let anyone under the house, from cost and materials to who can do the work.
Insulating a crawl space in the Los Angeles area usually costs about $1,700 to $7,500 per job. That's the area's going range, not our price, and where your house lands depends on the size, the material and what has to be fixed first. Your written estimate gives you your own number, and our work is satisfaction guaranteed.
Batts, spray foam or a mix all work if the insulation is pressed fully against the floor. Foam costs more and seals air as it goes on, but for most floors I'd seal the gaps and fit batts. If ducts and pipes run down there, national guidance says to insulate the crawl space walls instead, which keeps them inside the insulated part of the house.
In California, insulation work belongs to a licensed trade that the Contractors State License Board lists as insulation and acoustical contractors. Someone without a license can only take a minor job up to $1,000, and only if the work needs no permit and they have no employees. We're fully licensed and insured.
Holes in the subfloor around pipes and wires get sealed first, so the insulation isn't fighting a draft coming up through them. Any framing repairs come before that. If the dirt under your house is bare, or the ground cover is torn or missing, ground moisture and soil gases can get in, so ask me to check it on the same visit.
Yes, California's Energy Code includes efficiency requirements for changes to existing buildings, not only new ones, so insulating an older Pico Rivera house still falls under the state's rules. What applies to your job is part of what we check with the building office that covers your address before any work starts.
