How can you tell your walls need insulation?
Outside walls feel warm
Put your hand on a wall that gets the afternoon sun and you can feel the heat coming through. That usually means the space behind the drywall is empty or the old fill has slumped, and your AC runs harder all summer to keep up.
One room never matches
A corner bedroom stays hotter or colder than the rest of the house no matter where you set the thermostat. Two outside walls with nothing in them is a common cause, and the longer it goes, the more you pay to cool a room that won't hold it.
Street noise comes right through
Traffic, a neighbor's music or a leaf blower sounds like it's in the room with you. Hollow walls carry sound easily, and that won't get better on its own.
Is it worth insulating the walls of my house?
Wall insulation in Hawthorne, CA fills the empty space inside the outside walls of a house that's already built, without tearing out the drywall or the siding. It slows the heat coming through sun-facing walls, keeps rooms warmer on cold nights and cuts down the noise from outside, so if your walls are hollow, it's usually worth a look.
Most people call us because a room or two runs hot, the power bill climbs every summer, or they're about to redo the siding and wonder if now's the time. The price moves with how many walls we're filling, which side we work from, how much patching the finish needs and whether tile or cabinets sit on an outside wall, and the schedule mostly turns on access and any siding work you have planned. We're based in Hawthorne and work in the cities around it, and I'll come out, look at your walls and put the price and the plan for your house in writing.
Details to note before an estimate
- Year the house was built
- Which rooms or walls to include
- Siding type and its condition
- Any plans for new siding
How we handle wall insulation
Before we drill anything, I help you pick a side. Working from inside or outside comes down to which side is easier to reach and what shape your siding is in, and if new siding is on the way, we can time the wall work with that job so you only open the house up once. On older homes I tell you up front how much wall each method opens up, so you're choosing with the whole picture. Then our crew drills small holes near the top of each cavity, blows insulation in until it's full, plugs the holes and patches them. If we find something in a wall that worries me, like signs of a leak or wiring that doesn't look right, I'll show you before we cover it, because insulation over a problem just hides it.
Filled walls still can't stop air that slips around them at outlets, pipes and the spot where the wall meets the attic, so air sealing services often go along with a wall job. If part of your house sits below ground, those walls are a different job, and our basement insulation work covers them.
Work that often goes with insulating your walls
Air sealing services
Worth adding if you still feel a draft at the baseboards or outlets, because the air finds its way around even a full wall.
Basement insulation
For the walls that sit below ground, where the fill and the method aren't the same as for the walls above.
What happens after you call about your walls?
Call or send the form
Reach us at (424) 307-8033 or through the form, and we'll set a time for me to come out. Tell us which rooms bother you and the year the house was built so I come ready.
I look at your walls
I come out myself and check the walls from inside and out, along with the siding and what's in the cavities now. You get a written estimate with the price, which side we'd work from, how much wall each method opens and anything that should be fixed first.
Our crew fills the walls
A small crew I trained covers your floors and belongings, seals the leaks we find before the insulation goes in, then drills, fills and patches each cavity. Move anything fragile off the outside walls and we'll handle the rest.
We walk the job together
I check the work before we call it done, then walk it with you. You'll see what got filled and can ask anything you like.
Questions before you book wall insulation
How do I insulate existing walls without tearing them open?
Most finished walls get filled through small holes, one near the top of each cavity, the space between two studs, with blown-in insulation, loose fill blown through a hose. We also drill above doors, above and below windows and behind cabinets on outside walls so those pockets don't stay empty. If tile covers an outside wall in a bathroom, some of it may need to come off first, and I'll tell you at the estimate.
Is it better to insulate walls from the inside or the outside?
Inside is usually easier on your house's weather layer, and outside makes the most sense when the siding is coming off anyway. Drilling from outside goes through the house wrap behind the siding, the layer that sheds water, so it has to be patched or replaced, while working inside leaves it alone. If you're re-siding, that's the best time to go from outside, because the wrap can be checked or replaced and rigid foam boards can go on before the new siding.
How much does wall insulation cost in the Los Angeles area?
Wall insulation in the Los Angeles area usually costs about $1 to $4 per square foot of wall. That's the going rate around here, not our quote, and where your house lands depends on what I see when I look at your walls and siding. I'll put your price in writing after the visit.
How long does blown-in cellulose wall insulation last?
Cellulose that's put in right can keep working well for decades. How it's installed matters as much as the material, because loose fill has to be packed tight enough that settling doesn't leave empty spots, so our crew packs each cavity full instead of just pouring it in. We're insured, and our work is satisfaction guaranteed.
What should I know before insulating the walls of an older Hawthorne home?
If your house was built before 1980, federal guidance says to be aware of lead safety rules, and which ones come into play depends on how much the work disturbs your walls. So the useful question is how much wall surface each method opens, and as I mentioned above, you'll have that answer from me before you pick one.
Who is licensed to install wall insulation in California?
California's C-2 Insulation and Acoustical contractor class covers installing any kind of insulation for temperature or sound control, and you can read what it includes on the state licensing board's page. The state also splits California into climate zones, and the standards for a home's outer shell depend on the zone, so a Hawthorne house follows the rules for its own. We're fully licensed for this work.
