Air sealing services in Compton CA - a tighter house that still gets fresh air
Hot rooms upstairs and a power bill that keeps climbing usually mean attic gaps. We find them, check safety first and seal them.
Why is my house still drafty with insulation up there?
Air sealing closes the gaps between your attic and the rooms below, around wires, pipes, light fixtures and the hatch, so the air you paid to heat or cool stays in the house. At B&K Compton Spray Foam Insulation, we do air sealing services in Compton and the cities around it, and the sealing always goes in before any new insulation.
Most people call us because the room over the garage runs hot, the floors feel cold or the power bill keeps going up, even though there's insulation in the attic. Insulation slows heat, but air slips right past it at every gap, so piling more attic insulation on a leaky ceiling rarely fixes the draft. The price mostly turns on how big your attic is, how easy it is to get into, how many openings need sealing and whether old insulation has to come out first. The schedule turns on what the safety check turns up, because old wiring or a bath fan blowing into the attic gets sorted before we seal anything. I'll walk you through what your house needs once I've seen it.
How we handle air sealing services
Before we seal anything, I look for old wiring, bath fans and gas heaters or fireplaces, because a tighter house still has to get fresh air and some of those need fixing or venting first. Once those are sorted, our crew blocks the big openings, seals the smaller gaps around pipes, wires, light fixtures and the attic hatch, and keeps the eave vents clear so the attic can still breathe. Then, if you're adding insulation, it goes in on top of a ceiling that's already sealed.
Some houses leak from more than the attic. If air is coming up from below, we can pair the sealing with basement insulation, and where ductwork or moisture is part of the picture, closed-cell foam insulation, a dense foam that also blocks moisture, seals and insulates in one pass.
Sealing with a loose-fill top-up
This suits most attics with room to work and no ductwork up there, because sealing the gaps and then adding blown-in insulation, loose fill blown through a hose, costs less than foam. It's the route I usually recommend.
Foam where the ductwork runs
Foam costs more, but it seals air while it insulates, so it earns its price when your ducts live in the attic. We'll talk through whether the extra cost makes sense for your house before you choose.
Sealing with your insulation left in place
If the insulation you have is dry and clean, we move it aside, seal underneath and put it back. If it's soaked or full of droppings, it comes out first, because fresh work over a bad layer keeps the problem.
What air sealing services look like in Compton
Permits in the city go through Compton's Building & Safety Department, and it works in person only, with no online payments or submittals. Whether an air sealing job like yours needs a permit isn't something I'll guess at, so I tell you at the estimate, and if it does, we handle the paperwork with the city or county office for you. The city also asks for a current City of Compton business license with every permit application, so plan on that if you ever file one yourself.
California's energy code guidance says a poorly installed air barrier, the layer that's supposed to stop air, lets more heat in and out of the walls than the standard math predicts. Overhead it's the same story, and we find a lot of ceilings here with decent insulation and open gaps around lights, pipes and the hatch. We see it on jobs in Lynwood and Paramount too, so we look at the gaps before we look at the inches.

Air sealing questions from Compton homeowners
What does air sealing do for my home?
Done well, air sealing saves energy, lowers your bills and helps keep moisture problems out of the attic. It works by closing the ceiling joints and the openings where pipes, wires and fixtures pass from the attic into the rooms below, so the air you heat or cool stops leaking upstairs.
Is air sealing safe in a house with gas appliances?
Yes, when combustion safety and fresh air are handled first. The federal guidance on this puts combustion safety and ventilation ahead of the sealing and calls for whole-house ventilation so the home still gets enough fresh air once it's tighter. That's why I ask about gas heaters, gas fireplaces and any unvented kerosene heaters on the first visit.
What is the best way to seal and insulate an attic?
Seal first, then insulate. The federal attic guidance has the air sealing finished before new insulation goes in, and in an existing vented attic, the openings in the attic floor get sealed first. If you're planning new insulation, book the sealing as step one so it's done once and done right.
How do I know what my attic needs before air sealing in Compton?
A check of the attic before any sealing tells you. The federal attic guide has the work area checked for knob and tube wiring, the old kind run on porcelain knobs, vermiculite insulation, roof leaks, attic flooring and bath fans vented into the attic. Any of those changes the plan, so I go over what I found before you decide anything.
How much do air sealing services cost in Compton, CA?
Your price comes from your attic, and you'll get it at the estimate. Foam costs more than sealant and blown-in fill, adding insulation on top raises the total, and fixing a bath fan or old wiring first adds to it too. A small, easy-to-reach attic with sound insulation keeps it lower.
How do I know if air sealing was done right?
Ask whether the company tests the house before and after the work. A building-performance certification standard calls for blower door tests, a fan that shows how leaky the house is, before and after air sealing. You should also see metal blocking around hot flues, covers on older can lights that aren't rated for contact, and solid blocking over big openings.
