Open-cell foam insulation in Lancaster CA - a house sealed and insulated in one job
Hot upstairs, drafty rooms or a big power bill? We spray open-cell foam that stops air leaks and insulates, after we plan for moisture.
Is open-cell spray foam right for your Lancaster home?
Open-cell foam insulation in Lancaster, CA is a soft foam we spray onto the underside of your roof, into walls or around the room over the garage, and at the usual thickness it blocks air as well as slowing heat. That means one job handles both the drafts and the insulation.
Most people who call us about foam have a hot upstairs, a drafty bedroom or a power bill that keeps climbing, and they've heard spray foam is the answer. Sometimes it is, but foam costs more than other insulation, and if your ducts don't run through the attic, sealing the gaps and topping up blown-in insulation, which is loose fill blown through a hose, usually gets you more for the money. When foam does make sense, the price moves with how many square feet you want covered, how thick it goes and whether old insulation has to come out first, and the schedule mostly turns on when your household can be out of the house while the foam cures. The written estimate I give you after looking at the space spells out the work, so you know what you're paying for before we start.

Open-cell spray foam in attics and walls
How we install open-cell foam insulation
Open-cell is good at stopping air, and it's softer and quieter than the denser foams, but it won't hold back moisture, so before anyone sprays I work out where moisture control will go in your roof or walls. If we're turning an existing attic into a sealed space by spraying under the roof deck, the spray foam industry's guidance says the old insulation on the attic floor should come out, so that removal goes into the plan and the price from the start. Our crew covers and masks everything that shouldn't get foam, seals the gaps around the hatch, pipes and lights, then sprays to the depth on the estimate and checks it at the edges, not just the easy middle. Some foams and some jobs call for a covering over the foam, such as a coating or drywall, called a thermal or ignition barrier, and I'll tell you up front whether yours does before we clean up and hand the space back.
Because open-cell leaves moisture to another layer, a house on a raised floor often needs that layer down below too, and a crawl space vapor barrier keeps ground moisture from working up into the framing. For shops, offices and metal buildings, our commercial insulation work uses the same foam on bigger walls and roofs, and it's where I learned this trade.
Why Lancaster homeowners call Balanced Lancaster Insulation Company for spray foam
Trained where every stage gets checked
I spent my first years on office buildings, warehouses and metal buildings, where each stage got checked before anything was closed in, and we've been in business since 2013. That matters with foam, because once it's sprayed nobody sees what's underneath it.
I see your attic before pricing
I come out for the estimate myself and look at the space before I write anything up. You hear what needs fixing first from the person whose name is on the estimate, not from a salesperson.
Licensed in California, insured too
The state licensing board counts anyone who installs insulation for temperature or sound control as an insulation contractor, and we're fully licensed and insured. Satisfaction guaranteed on every job.
On an open-cell job, what matters most is settling where moisture control goes before the foam goes on, because it's hard to undo once it's sprayed. We're based in Lancaster and work in Palmdale, Quartz Hill, Rosamond and many of the cities around them. Call (661) 952-4049 or send us your details with the area you want done, your attic type and any health concerns in the house.

What happens after you call about spray foam in Lancaster?
Call or send the form
Call (661) 952-4049 or send a message, and we get back to you to set up a visit. It helps to know which rooms bother you most and whether anyone in the house has asthma or allergies.
Walk the space with me
I look at the attic, crawl space or walls, note anything that should be fixed before foam covers it and then write up the estimate. You get the work, the order we'll do it in and the price on paper, so there are no surprises later.
Spray day with our crew
My longtime crew lead runs the job with our installers, we seal before we insulate, and I check in along the way. Temperature and humidity change how foam cures, so we look at the day's conditions before we start, and your household is already out of the house by then.
Come home and walk it
Once the foam has cured and the house has been aired out and cleaned, you come back in. I walk the finished work with you so you can see the coverage at the edges and around the hatch.
Open-cell foam questions from Lancaster homeowners
Is open-cell or closed-cell spray foam better for my home in Lancaster?
Open-cell is usually the better fit when there's room for the depth and moisture control can go in another layer, and closed-cell wins where space is tight or the foam itself has to block moisture. Typical closed-cell insulates at about R-6 per inch and open-cell at about R-3.6, R-value being how well insulation slows heat, so open-cell needs more thickness to match. If closed-cell suits your job better, I'll say so and point you to closed-cell foam.
How long do we have to stay out of the house after open-cell spray foam?
Plan on at least 24 hours away, because CPSC staff guidance tells residents to leave for at least that long. EPA guidance adds that nobody goes back in until the foam has finished curing and the house has been aired out and cleaned, so we set your re-entry time, meaning when the family and pets can come home, with you at the estimate.
Does open-cell foam insulation stop moisture?
No, open-cell foam is vapor open, so water vapor passes through it and it can't be the layer that holds moisture back. That job goes to another part of the wall or roof. Where the foam turns your attic into a sealed space, federal building guidance says that attic also needs a way to remove moisture, so we build that into the plan before we price it.
How much does open-cell spray foam insulation cost in Lancaster, CA?
Spray foam insulation in the Los Angeles area usually costs about $2 to $5 per square foot of area covered. That's the going rate around the region, not our price. Where your job lands depends on the square footage, how thick the foam goes and whether old insulation has to come out first, and I give you a Lancaster price in writing after I've seen the space.
How do I know if spray foam is safe for someone in my house with asthma?
Read the product information for the foam before you agree to it, because the same safety guidance says people with asthma, respiratory allergies, skin conditions or an earlier reaction to isocyanates, the chemicals spray foam is made from, should review it carefully. If it doesn't sit right, other insulation is a fair choice, and I'd rather tell you that at the estimate than talk you into foam.
Do California energy rules apply to insulating an existing attic in Lancaster?
Yes, the state's energy standards have a section that covers insulation added to existing attics, so a Lancaster attic retrofit falls under it. The same section covers insulation on existing heating and cooling ducts and water heaters, which matters when your ducts run through the attic we're spraying, and we go over how it applies to your house at the estimate.

Commercial insulation
If you own or manage a shop, office or metal building, the same foam can quiet the space and cut drafts on a larger scale.
Crawl space vapor barrier
Open-cell lets vapor through, so a barrier over the dirt under a raised floor keeps ground moisture from getting into the house.
