Filling the walls you already have
Wall insulation in South Whittier usually means drill and fill on an older house: we drill small holes, blow insulation into the empty spaces inside the wall and seal the holes, a method that suits uninsulated walls in a mild climate like ours.
Most people call because a bedroom stays cold on winter mornings or the back of the house won't cool off, and on older houses the walls behind those rooms are often empty. What moves the price is how many walls need filling, whether we work from outside or inside, and how you want the holes finished, while the schedule turns mostly on how many rooms we're working in and whether your job needs a permit. I'll give you the figure for your house at the estimate.
Learned on the crew first
I started out hauling bags and feeding hose on an insulation crew before I opened this business in 2013, so I know what a good fill looks like from inside the wall.
Problems fixed before walls get filled
If a wall has a leak or old damage, I'll tell you to get that fixed first, because insulation packed over a problem just hides it until it gets worse.
You know what you're paying for
Before we start, you'll know which walls we're filling, which side we're working from and how the holes get finished, so you're not guessing about what the bill covers.
How we fill a finished wall
I look first at which walls are empty and which side to work from, because that decides the rest of the job. Then our crew lead runs the install. The crew drills small holes, packs each cavity full and tight so the insulation won't settle and leave an empty band at the top, and closes the holes back up, and I check in on the work while they're there. A loose fill is the usual mistake on this job, and a full, dense one is what you're paying for. When we work from inside, we cover your floors and seal off the room so the dust stays in that room and out of the rest of the house.
Filled walls work best when the drafts around them are stopped, so we often pair this job with air sealing services, closing gaps around pipes, the attic hatch and other openings so the new fill isn't fighting moving air. If your house has a basement, basement insulation covers the walls down there, which is a different job from filling the walls upstairs.
Planning wall insulation for a South Whittier house
State energy rules cover older homes
California's Energy Code sets efficiency rules for changes to existing homes, not just new ones. When we plan your walls, we check what those rules ask of your job before the crew drills.
Licensed and fully insured
California licenses and regulates its construction contractors through a state board. We're licensed and fully insured, so the crew drilling into your walls is covered while it works on your house.

Questions about insulating existing walls
Straight answers to what South Whittier homeowners want to know before they let anyone drill into their walls.
Can you add insulation to existing walls from the outside or the inside?
Yes, either way works, and I'll tell you which fits your house at the estimate. From outside, the crew plugs and seals the holes and, where the wall has a layer that keeps water out, repairs it so rain can't get in. From inside, the holes get patched or covered with a chair rail, a strip of trim along the wall, and you pick which before we start.
How much does blown-in wall insulation cost in the Los Angeles area?
A blown-in insulation project in the Los Angeles area usually costs about $1,600 to $3,600 per job. That's the going rate around here, not our price. Your own figure comes from the estimate at your house, once I've seen how many walls need filling and which side we'll work from.
How much can an insulation contractor ask for up front in California?
Under the state licensing board's rules, a contractor on a home improvement job can ask for a down payment of no more than $1,000 or 10 percent of the total contract price, whichever is less. Any later payments have to be written into the contract and match work done or materials delivered, so check that before you sign with anyone.
Can blown-in insulation fill walls with pipes or boards inside them?
Yes, blown-in insulation can fill oddly shaped or closed-off spaces and pack in around pipes and other things inside the wall. Packed tight enough, it also slows the air that drifts around inside the wall. If a space is closed off from the hole we drilled, we drill another so that part of the wall doesn't stay empty.
What should I ask an insulation contractor before they blow insulation into my walls?
Ask how the crew makes sure your wall can take the air pressure of blown insulation, and how it repairs the holes so the fill doesn't blow back out. Clear answers to both tell you the crew has done this before. I'll go over both with you at the estimate, before anyone drills.
