Wall insulation we put in around Bell

  • Blown-in for closed walls

    Loose fill blown through a hose into walls that are already closed up, packed in so it reaches odd, hard-to-reach spaces without tearing out your drywall or plaster.

  • Batts for open, even walls

    Precut insulation fitted between the studs while a wall is open for a remodel or addition, and usually the cheaper choice when the spaces are even.

Can you insulate my walls without tearing them out?

Wall insulation in Bell fills the hollow spaces between the studs inside your walls, so rooms hold heat in winter, stay cooler in summer and let in less street noise. When the walls are already closed, we can usually blow it in through small holes instead of tearing out drywall.

Most calls start with a room that won't stay comfortable, or a landlord hearing about the cold side of a unit again. The price moves with how many walls we're doing, how they're framed, what's in them now, your siding and what your inside walls are made of, since those decide whether we blow it in or fit batts. The schedule turns mostly on whether something has to be fixed before insulation goes in. I look at all of it at the estimate and give you your price in writing.

Wall insulation and the prep around it

Whether we blow it in or fit batts depends on how your walls are built and what's in them now, so nobody gets a price from me before I've looked.

  • Look inside the walls

    We check the framing and what's in the wall now, and if cold floors are the real complaint, basement insulation may fit better.

  • Cover floors, close off the room

    We lay covers on your floors and close off the work area so dust and debris stay in the one room we're working in.

  • Seal the gaps first

    We close gaps around outlets, pipes and window trim with air sealing first, because insulation can't stop a draft blowing past it.

  • Fill every space full

    Blown-in gets packed into each space between the studs all the way up, because a loose fill settles and leaves hollow spots.

  • Finished walls get a second look

  • Licensed and insured, crew works clean

    We're licensed and insured. I want my crew working safe in your house and leaving it clean when they go. Your satisfaction, guaranteed.

  • Told straight if it isn't ready

    I'd rather tell you a job isn't ready than take your money for it, so if something has to be fixed before insulation goes in, you'll hear it from me.

Wall insulation questions we hear

How much does wall insulation cost near Bell?

Insulating walls in the Los Angeles area usually costs about $1 to $4 per square foot of wall. Where your job falls turns on the method and what's in your walls now, so I put your price in writing after I've seen them.

What is the best way to insulate walls that are already closed up?

For closed walls, blown-in is usually the right call, because it reaches odd, hard-to-reach spaces without tearing out drywall or plaster. Batts only make sense when a wall is open and the spaces between studs are even, and then they're often the cheaper way to go.

Can you insulate the walls of an older house in Bell?

Usually, yes, but older houses can hide knob and tube wiring, the original wiring in many old homes, along with lead paint outside, asbestos or moisture, and any of those can stand in the way. When I look at your walls, I'll tell you what I see and what has to be handled before insulation goes in.

How do I find out if I need a permit for wall insulation in Bell?

Call the City of Bell at (323) 588-6211, extension 2611, and they'll tell you whether your job needs a permit. You can leave it to us too, since we check with the office for your address before we start.

What happens to the holes in my walls after blown-in insulation?

We close them up when we're done. Holes drilled from inside get patched, or covered with a chair rail molding if that suits the room, and holes drilled from outside get plugged and sealed, with the water barrier behind the siding repaired so rain stays out.

What license does a wall insulation contractor need in California?

Look for the state's C-2 insulation and acoustical class, which covers installing any insulating material for temperature or sound control. Ask the contractor for their license number and check it with the state licensing board before anyone starts drilling.

Wall insulation in Bell and the cities around it

In Bell, the city's Building and Safety Division issues construction permits and inspects the work, and most homeowner projects need a combination permit. Whether your wall job needs one is the city's call, and rules aren't the same in Bell, the other cities and the county areas, so we check with the office for your address before we start and pull the permit if it's needed. California also sets some insulation standards by climate zone, so wall rules aren't the same everywhere in the state, which is one more reason we check first.

Most of what we get into around Bell is older houses with the walls closed up and little or nothing inside them, owned by families or rented out. We're based in Bell and see the same kind of houses on jobs in East Los Angeles and Walnut Park, so the work goes the same way there.
