Insulation contractor services in Hawthorne, CA
D&J Hawthorne Insulation Services is an insulation contractor in Hawthorne, CA, with 16 services for hot rooms, cold floors and tired attics. The price turns on the size of the space, what's already up there and whether it has to come out first. The schedule turns on any repairs needed before we insulate. Our free on-site estimate puts your price and plan in writing.
We spray foam that seals air and insulates in one pass, which makes it a good fit when your ductwork runs through the attic.
If your upstairs stays hot all afternoon, we check what's in the attic now and bring it to an even depth, edges included.
Blown-in insulation is loose fill we blow through a hose, so it settles into corners and around framing that batts tend to miss.
We look at the whole house, from the attic and walls to the crawl space, and put insulation where you're losing the most.
When old insulation is soaked, flattened or full of droppings, we bag it and haul it out, so the new material starts clean.
Cold floors over a crawl space usually mean bare or fallen insulation underneath, and we put it back up and hold it in place.
We fill the empty wall cavities in older houses through small holes, then patch them, for rooms that feel drafty along outside walls.
Air sealing is closing the gaps where outside air gets in, around outlets, plumbing and the wall to the garage, so rooms feel less drafty.
We insulate basement walls and the band where the house sits on the foundation, for homeowners turning a chilly lower level into usable space.
Closed-cell foam is a dense foam that also blocks moisture, so we use it where dampness is a concern, like crawl spaces and basement walls.
Open-cell foam is a softer, lighter spray foam that fills odd-shaped cavities and quiets sound, a common pick for rooflines and interior walls.
For owners of shops, offices and other commercial buildings, we look over the ceilings, walls and roof decks, then insulate and seal them.
A damp crawl space can make the floors feel clammy, so we lay a plastic sheet over the dirt to keep ground moisture down.
We install vapor barriers in walls, floors and attics that need one, on the correct side so moisture doesn't get trapped in the framing.
Can lights, the attic hatch and holes around pipes let attic heat leak into your rooms, so we seal them from above before any insulation.
Retrofit insulation is adding insulation to a finished house without tearing it apart, for older homes built with little or none in the walls.

About usWhat happens after you call
Call or send the form
Call (424) 307-8033 or fill out the form and tell us what you're noticing, like a hot bedroom, cold floors or a power bill that keeps climbing. We reply to every call and message within one business day to set a time for me to come out.
I look and write it up
I come out myself and look at the attic, walls or crawl space, including how many inches are up there now. You get a written estimate with the price and the plan, and it lists anything that should be fixed first. It's free, and there's no pressure to book.
The crew does the work
On install day, a small crew I trained covers your floors and belongings, then seals the leaks before any insulation goes in. If something new turns up once the attic is open, I'll tell you what it is and what it means for the job before we go further.
We walk the job together
Before we call it done, I check the crew's work, then walk the finished job with you. You'll see what went in and where, and no question is too small, because you should understand what you paid for.
