Open-cell spray foam fills the walls and roof framing of an unfinished attic, with a window and exposed ducts.

Is open-cell spray foam right for my attic in East Los Angeles?

Open-cell foam insulation is a soft spray foam our crew applies in place in East Los Angeles attics and walls, where it expands into the gaps, stops air moving through them and insulates in the same pass.

Usually it starts with an upstairs that stays hot into the night, a room over the garage nobody wants to sleep in, or a power bill that climbs every summer. The price moves with how much area we spray and how thick, whether flattened or soaked old material has to come out first through insulation removal, and whether the roof needs repairs before foam goes under it. The schedule turns on those same repairs, any permit your address needs and the hours the house has to air out afterward. At the estimate, you get a written list of what your job needs and what has to come first, so you see the whole order before you decide.

How we install open-cell foam insulation

First we check the roof, because leaks and worn roofing need fixing before foam goes under it, and foam can hide a slow leak until it shows up in the framing. If the old insulation up there is flattened, soaked or full of droppings, we take it out, since new material over a problem only hides it. Then our crew covers what shouldn't get foam, sprays the open-cell to the depth we agreed on, trims anything that overfills and cleans up before we leave.

Open-cell suits jobs where stopping air and quieting a room matter more than holding back moisture, so if your trouble is damp, I'll say it isn't the right pick. Under the house, a crawl space vapor barrier usually does more for moisture than any foam would. We also spray open-cell in shops and offices as part of our commercial insulation work, where it's often there to cut noise between rooms.

Open-cell in walls and between floors

This suits a bedroom on a busy street, the room over the garage or a wall that's already open for a remodel, because the soft foam fills every gap and dulls the sound coming through. It isn't the pick for a wall that gets damp.

Sealing the gaps and topping up loose fill

Foam costs more because it seals air while it insulates, and in a lot of attics, attic air sealing around the lights, pipes and hatch, then topping up blown-in insulation, the loose fill blown through a hose, is the better buy. I'll recommend it when it fits, unless your ductwork runs through the attic.

Open-cell foam insulation permits in East Los Angeles

In East Los Angeles, building permits come from LA County Public Works, which runs an East Los Angeles Building and Safety Office at 4801 E. 3rd St., with service and intake at (323) 881-7030. The county's permit list names alterations, repairs, replacements and mechanical systems but not insulation by name, so whether your foam job needs one is a question for that office. Before anything else, we check which office covers your address, because some homes nearby fall under a city's own building department instead of the county, and when a job calls for a permit, we take care of that step with them before work starts.

A lot of the houses we see here are older, with low attics, ducts running overhead and gaps around the hatch and pipes that nobody ever closed. We do the same work in Montebello, Monterey Park and the other cities around East Los Angeles.

Questions about open-cell foam in East Los Angeles

How much does spray foam insulation cost in the Los Angeles area?

Spray foam insulation in the Los Angeles area usually costs about $2 to $5 per square foot installed. That's the going rate around here, not a quote, and where your job lands depends on how much area we cover, how thick the foam goes and what has to be fixed or taken out first.

How do I choose between open-cell and closed-cell spray foam?

Pick closed-cell where moisture is the worry and open-cell where blocking air at a lower price is the goal. Closed-cell insulates more per inch, is rigid and nearly blocks water vapor, while open-cell stops air but lets vapor pass through. Closed-cell foam insulation costs more to install because it takes more material.

How do I know if my attic should be sealed with spray foam under the roof?

Sealing the attic so it becomes part of the house's cooled and heated space is worth considering when it holds ductwork or equipment, or will become living space. A roof that's hard to vent or a ceiling that's hard to seal points the same way. Any attic sealed like this needs a way to remove moisture, so that has to be part of the plan from the start.

Does my roof need work before spray foam insulation goes in?

Often it does. The shingles or roof membrane should be inspected first, with any leaks fixed and damage repaired, and if the roof is at or near the end of its life, replacing it first is worth considering. That's why the roof's age is one of the first things I ask about, since it can change the whole budget.

Is spray foam safe if someone in my house has asthma or allergies?

People with asthma, respiratory allergies, skin conditions or a past reaction to isocyanates, a chemical used in spray foam, should go over the product information carefully and may want to consider another kind of insulation. Tell me at the estimate so we can look at the product details together before anything is chosen.

How long before my family and pets can go back inside after spray foam?

Some foam makers recommend waiting 24 hours after professional spraying before anyone returns, though the time can vary by product. You can ask us for the maker's ventilation and re-entry times, meaning when you can come back, for the exact product on your job, and plan your time away around them.

What license does a spray foam insulation contractor need in California?

California's C-2 insulation and acoustical classification covers contractors who install any insulation for heat or sound control, and that includes spray foam. Ask whoever you hire which license they hold before work starts.
