Older houses across East Los Angeles
East Los Angeles isn't a city of its own. It's one of the County's unincorporated areas, so on a job here we deal with County offices instead of a city hall. On the streets off Whittier Boulevard and across the rest of East LA, the houses we get called to are mostly older single-family homes set close together. A lot of them had a room added in back or over the garage years after the house went up. Attics tend to be low and tight, and the crawl space under a raised floor is often bare. The spot where an addition meets the old roof is usually where we find the gaps that leave one room hotter or draftier than the rest of the house.
We're based in Pasadena and do the same attic and crawl space work here that we do in El Monte and South Pasadena. On houses this age, I'd rather crawl the whole attic before I quote, because old wiring, a stained roof board or a buried vent changes what has to happen before any new insulation goes in.
Our services in East Los Angeles, CA
Many East LA houses went up with little in the walls and floors and were added onto over the years, so comfort changes from room to room. Our home insulation work starts with a look at the whole house, and then we take on the attic, walls and crawl space in the order that matters most for yours.
Low attics over older ceilings are full of small openings around light fixtures, pipes, wires and the hatch, and air moves through them no matter how much insulation sits on top. We seal those gaps before anything else, because that's the step that lets the rest of the job do its work.
Old insulation in these attics is often packed flat, stained from an old roof leak or full of droppings, and new material laid over it just keeps the problem. We bag it out, clean up and check the wood and wiring underneath before anything new goes in.
A raised floor over a bare crawl space is one of the main reasons for cold floors in the older houses here. We insulate under the floor and close up the openings so the rooms above stop pulling air from below.
When an attic already has some insulation that's dry and clean, topping it up with blown-in, which is loose fill sent through a hose, is usually the best value. We keep it just as deep at the edges as in the middle and keep it off the eave vents so the attic can still breathe.
Additions and garage conversions here were sometimes framed with empty walls, so that room never feels like the rest of the house. We can fill closed walls through small holes and patch them, or insulate open walls if you're already remodeling.

Call or send a request
Call (626) 345-7649 or fill out the form, and we'll set up a visit at a time you can be home. I'd like you there for the walk-through so you see what I see.
Walk the attic together
I come out myself and look at the attic, walls or crawl space with you, checking for leaks, wet spots and old wiring. You get a written estimate with the price, what gets done first and why, before you agree to anything.
Pull permits and do the work
If your job needs a permit, we pull it with the County and set up the inspection. Then our own trained crew does the sealing, removal or insulating, and we tell you ahead of time if you need to be out of the house.
Go over the finished job
When the crew wraps up, I go over the finished job with you, up in the attic if you want to look. That's when we call it done.
East Los Angeles insulation questions
Who issues insulation permits in East Los Angeles?
LA County Public Works issues building permits in East Los Angeles, because it's an unincorporated part of the County, and the department has a Building and Safety office right in East LA. The County's list names alterations, roofs, windows and mechanical systems but not insulation by name, so whether your job needs one depends on the work. We find out from the County for your address, and if a permit is needed, we pull it and handle the inspection.
Does an insulation contractor in East Los Angeles need a California license?
Usually yes, because the state's Contractors State License Board requires a license when a job needs a building permit, uses any additional workers or runs $1,000 or more in labor and materials. The contractor has to hold that license before giving you a bid, not just before starting work. We're licensed and fully insured.
When is the first inspection due on a County permit in East Los Angeles?
The County wants the first inspection requested within 12 months of getting the permit, with follow-up inspections every 6 months to keep it active. When we pull a permit for your job, we schedule the inspections so the permit doesn't lapse.
How much does insulation cost for an older house in East Los Angeles?
The price mostly comes down to whether old insulation has to come out, how much sealing the attic needs and whether you go with spray foam or loose fill. A low, tight attic takes more time to work in, and a permit or removal work can stretch the schedule. The free estimate gives you your price and the order of work in writing.
What is the best way to insulate an older attic in East Los Angeles?
For most older houses here, sealing the gaps first and then topping up with blown-in loose fill is the better buy. Spray foam costs more and seals air as it insulates, so I recommend it when the ductwork runs through the attic and belongs inside the sealed space. Either way, the old material has to be dry and clean before anything goes over it.
How long do we have to stay out of the house for insulation?
For air sealing and blown-in work, you can usually stay home, because the crew works up in the attic and keeps the mess there. Spray foam is different, since the foam maker sets a re-entry time, which is how long before people can come back inside, and you, the kids and the pets stay out until it's passed. We tell you the wait for the product we're using before the work day.
