Del Aire houses and what we find in them
Del Aire is a small unincorporated community next to Hawthorne, a short drive from our base in Lawndale. It's mostly houses, and more households here own their home than rent it, so the calls tend to come from people who plan to stay and want the place comfortable year round.
The houses we get into here are mostly single-family homes, many of them older, with a low attic you crawl through rather than walk. That shapes the job, because the careful work happens at the edges, where the roof meets the walls and coverage usually runs thinnest.
Insulation services for Del Aire homes and buildings
Spray foam insulation
Spray foam fits when your ducts run through a hot Del Aire attic, because it seals air and insulates in one coat right at the roof deck.
Attic insulation
Most hot upstairs rooms here start in the attic. We check how many inches are already up there, then even out coverage so the edges aren't left thin.
Blown-in insulation
Blown-in, loose fill blown through a hose, is usually the quickest way to top up a settled attic floor in an older house without tearing anything open.
Home insulation
When the whole house feels drafty, not just one room, we look at the attic, walls and floors together and write down the order we'd tackle them.
Insulation removal
Old insulation that's soaked, flattened or full of droppings has to come out first, because new material laid over it just keeps the problem in place.
Crawl space insulation
Cold floors in a raised Del Aire house usually trace back to the crawl space, where we insulate under the floor once any damp spots are dealt with.
Wall insulation
Some older walls here have little or nothing in them. We fill the cavities through small holes and patch them, so the room stays livable.
Air sealing services
Air sealing, closing gaps before insulating, stops the drafts around can lights, pipes and the hatch that make a hot room feel worse in summer.
Basement insulation
Basements aren't common in houses around here, but when a home or building has one, we insulate the walls once we've checked for water coming through.
Closed-cell foam insulation
Closed-cell foam, a dense foam that blocks moisture, makes sense in tight spots near damp ground or under a floor where loose fill won't stay put.
Open-cell foam insulation
Open-cell foam is lighter and softer than closed-cell, and it suits a dry attic roofline, where it seals air and cuts down on outside noise.
Commercial insulation
Property managers call us for small commercial buildings with roof decks, walls or offices that run hot, and we plan the work around your tenants.
Crawl space vapor barrier
A vapor barrier over the crawl space dirt keeps ground moisture away from the floor framing, and we lay it only after any standing water is fixed.
Vapor barrier installation
We put vapor barriers in walls, floors and ceilings where moisture could reach the framing, and we check which side they belong on before anything goes up.
Attic air sealing
Before anything gets added up top, we seal the attic floor so hot attic air stops leaking into the rooms below through gaps around wiring and ducts.
Retrofit insulation
Retrofit work adds insulation to a finished house without gutting it, which suits older Del Aire homes where tearing out walls or ceilings isn't worth it.

Working in Del Aire under Los Angeles County rules
Del Aire is unincorporated, which means Los Angeles County acts as its local government, and permits for work here come from LA County Public Works, not a city hall. Before we start, we check with the county whether your job needs one, and when it does we take care of the paperwork and the inspection, so that answer can move the start date. You can check up on us too. The Contractors State License Board licenses contractors across California, and the county's Treasurer and Tax Collector issues a County Business License to businesses in unincorporated areas whose work is on its licensed list. We're fully licensed and insured.
We're based in Lawndale, a short drive away, and we work across the South Bay, so we run the same address check in Manhattan Beach and other cities, where a different office may handle the permit. Here, the price moves with what's already in your attic and how much prep it needs before anything new goes in, and the schedule moves with the permit question and anything I find that has to be fixed first. Your written estimate spells out both, step by step.
Summer heat and older attics in Del Aire
The county's climate profile for Del Aire rates extreme heat as a bigger concern for the community than wildfire, flooding or drought, and inside a house that shows up as an attic that bakes all afternoon and a bedroom or the room over the garage that won't cool down. When the ducts run through that attic, the cooled air warms up before it reaches you and the power bill climbs. We seal the gaps first, then insulate, so the new material isn't fighting a draft.
Older attics here usually have insulation that has settled, been pushed aside by past repairs or picked up droppings, and the eave vents are sometimes buried under it. We pull out what's spoiled and keep the vents clear so the attic can still breathe.
How a Del Aire insulation job runs, step by step
Here's how it goes from your first call to the walk-through, so you know who you'll see at the house and what you'll have in hand.
Call us or send the form
Call (424) 528-1317 or send the form, and we'll get back to you to set a time for the visit. Plan to be home so I can get into the attic and crawl space.
I measure and check first
I come out myself, measure, and note anything that has to be dealt with first, like old wiring, damp spots or insulation that looks like vermiculite. Nothing gets priced until I've seen it, so the number fits your house instead of a guess.
Read your written step list
You get a written estimate that lists each step in the order we'd do it, with sealing before insulating and removal before anything new goes in. If something isn't ready yet, it says so.
We install and walk through
If you go ahead, we sort out any permit with the county, and our crew does the install with me on site. When it's done, we walk the finished job with you.
Questions about insulation in Del Aire
How much does it cost to insulate an attic in Del Aire?
We price each Del Aire attic after seeing it, because what's already up there decides most of the cost. The biggest swings are whether old, wet or dirty insulation has to be vacuumed out first, how many gaps need sealing around can lights, pipes and the hatch, and how low and tight the attic is to work in. Choosing foam over loose fill raises it too.
Do I need a permit to insulate my house in Del Aire?
The county's list of permit-free work doesn't settle it for insulation, so it should be checked for your address before work starts. That list names finish work like painting, tiling, carpeting and cabinets, and even work on it can still need separate electrical, plumbing or mechanical permits. You can ask the local office shown on the county's Building and Safety permits page, and if you hire us, that check is already part of the job.
How do I find out if my Del Aire address is unincorporated?
Look your address up in the county's Z-Net tool, found through the county's unincorporated area services site, which shows whether a property sits in an unincorporated area or inside a city, along with its zoning. Your zip code won't always tell you, because many zip codes in the county cross county and city lines. If your address turns out to be inside a city, a different office may handle the permit.
How much can an insulation contractor ask for up front in California?
Under the state board's guidance, a down payment on a home improvement job can't be more than $1,000 or 10 percent of the contract price, whichever is less. Any other payments should be written into the contract and tied to work finished or materials delivered. The board says these rules apply to every home improvement project, and insulation is home improvement.
How long do we have to stay out of the house after spray foam insulation?
The foam maker's instructions set the re-entry time, the point when it's safe for you, your kids and pets to come back in, and it changes from one product to the next. We go over that time with you before the job is booked, so you can plan a night away if you need one. With blown-in loose fill you usually don't have to leave at all.
What is the best way to keep a Del Aire house cooler in summer?
For most houses here, sealing the gaps in the attic floor and then topping up the loose fill to an even depth does the most for the money. Foam at the roofline is worth its higher cost when your ductwork runs through the attic, because it keeps that space closer to room temperature. I'll tell you which one fits after I've been up there.
