Does my South Gate attic need air sealing?
Attic air sealing in South Gate means closing the holes between your rooms and your attic, around light fixtures, pipes, wiring and the hatch, so the air you pay to heat or cool stops slipping upstairs and attic dust stops drifting down. It's done before any new insulation goes in.
Most calls I get start with a drafty room, an upstairs that's hot or cold when the rest of the house isn't, or a power bill that seems too big for the house. The price moves with how many big holes your attic has, how easy it is to crawl around in and whether old insulation has to come up so we can reach the gaps underneath. The schedule turns on what I find when the hatch opens, since some problems have to be fixed before sealing starts, and the estimate gives you your own figure once I've seen it.

How we handle attic air sealing
I start by looking the attic over, because a leaking roof or a bath fan blowing into the attic gets fixed before we seal anything, and a federal attic sealing guide also says to stop for live knob and tube wiring, the old cloth-covered kind on porcelain knobs, or vermiculite, a pebbly gray-brown loose fill. Then we go after the big holes first, like chases, the open shafts where pipes and ducts run, and the attic hatch, since that's where the payoff is. Narrow cracks usually get caulk and wider gaps get spray foam, but near the furnace flue we use heat-rated caulk and not foam, because foam doesn't belong against a hot pipe. Soffit and gable vents and any combustion air ducts have to stay open to do their job, so we leave them clear and clean up before anything else goes in.
Sealing comes before insulation, so the next step is often retrofit insulation over the sealed attic floor. If your ducts run through the attic, spray foam insulation can seal and insulate in one go.
Seal the gaps and top up
This suits most attics, where the ducts aren't up there and some insulation already is. For those houses I'd pick sealing plus blown-in insulation, loose fill blown through a hose, over foam, because it usually does the job for less.
Spray foam where ducts run
If your ductwork lives in the attic, foam can be worth its higher cost because it seals air while it insulates the space around those ducts. I'll tell you if your attic doesn't need it.
Old insulation out, then seal
When the old insulation was soaked or full of droppings, it comes out first, because sealing and adding over it keeps the problem in your attic. Clearing it also gives us a plain look at every gap.
How can you tell your attic is leaking air?
Drafts with the windows shut
You feel air moving near outlets, ceiling lights or the hall even with everything closed. That's usually house air trading places with attic air through gaps, and you keep paying for what slips out.
One room never matches
The room over the garage or an upstairs bedroom runs hotter or colder than the rest of the house. Open gaps overhead are often why, and turning the thermostat harder just raises the bill.
A power bill that climbs
Heating or cooling costs keep rising though nothing about how you live has changed. Air escaping into the attic is a common cause, and until it's fixed you're paying for air you never feel.
Dust lines on the ceiling
Gray streaks around light fixtures or vents, or dust that settles fast in rooms under the attic, often mean attic air is filtering through. Left alone, it keeps carrying that dust into your rooms.

Questions about sealing your attic
These are the questions I hear most about attic air sealing in South Gate. If yours isn't here, call or send the form and ask about your own house.
How do I know if my attic needs air sealing?
The surest way is to have someone look, because the signs above tell you a house might be a good candidate but not where the holes are. Up in the attic, leaks usually show as darkened insulation over gaps and open shafts around pipes and ducts. Two or three of those signs together is a good reason to have the attic checked.
How much does attic air sealing cost in the Los Angeles area?
Attic air sealing in the Los Angeles area usually costs about $350 to $2,300 per job, which is the going rate around here and not a quote from us. Where your house lands in that range comes down to what I find once I'm up there.
Is attic air sealing safe if I have a gas furnace or water heater?
It can be, but sealing can sometimes cause gas or oil appliances that vent naturally to back-draft, pulling their exhaust back into the house instead of up the flue. ENERGY STAR suggests having those appliances tested by a Home Performance Contractor before and after the sealing. Plan that test ahead of the job and let me know who's doing it so we can work around it.
Who is allowed to do attic air sealing in California?
Anyone who builds or alters a building in California has to be licensed by the Contractors State License Board when labor and materials come to $500 or more, a figure from an older board guide, so check with the board for today's amount. That guide also says contractors need the license before they bid, so it's fair to ask for it before you take a bid.
Do I need a permit for attic air sealing in South Gate?
It may, and the city's permit list doesn't settle it, so the place to ask is South Gate's Building and Safety Division at (323) 563-9549. The division typically requires permits for home repairs and alterations, and its list names re-roofing more than 100 square feet, which matters if a roof leak has to be fixed before we seal. When a job needs a permit we pull it and set up the inspections, and if we're not sure, we check with the city before work starts, or with the county office for houses in areas like Walnut Park and Florence-Graham.
How long does attic air sealing take, and do we have to leave the house?
It comes down to how big your attic is, how many large holes it has and whether a repair has to happen first, so I'll tell you what to expect once I've seen it. Caulking usually doesn't mean leaving, and if spray foam goes on any wide gaps, I'll give you the re-entry time, when it's fine to come back inside, before we start.
