Hot upstairs rooms and a climbing power bill usually mean air is slipping through. Open-cell foam seals those gaps while it insulates.
Open-cell foam insulation in Lubbock is a soft spray foam we put into walls and along rooflines, and it seals air leaks and insulates in the same coat, so rooms that ran hot or drafty stop fighting the rest of the house.
Most calls I get about foam start with the room over the garage that never cools off, or a power bill that keeps going up while the house still feels drafty. Usually that's air moving through gaps nobody sealed, and foam is one good way to stop it, though not the only one. We're Airlock Lubbock Spray Foam Insulation, based in Lubbock and working in the cities around it. Satisfaction guaranteed on every job.
What moves the price is how many square feet need foam, how thick it goes, whether the walls are open studs or finished drywall, and whether old insulation has to come out first. The schedule turns on how much repair comes before we spray, when your household can be away, and whether the city wants a permit for your job. I look at the space in person, go over what I see, and send you a written estimate with your own number.
You'll talk with me before anyone sprays anything, and you'll see me again at the end.
I started as a helper on an insulation crew around Lubbock and have run this business since 2021, so I'm the one who climbs into the attic or checks the wall. I talk through what I find while I'm standing there, including anything I'd fix before foam goes in.
After the visit I send a written estimate, so you can read it over and ask me the same question twice if you need to. When you're ready, we set a day that gives your household time to plan around being away.
We're licensed and insured. Our own crew does the work, and when they're done I walk the finished job with you so you can see what we did.
First I explain where open-cell makes sense in your house and where closed-cell foam, the dense kind that blocks moisture, would do better, and I'll tell you if foam isn't worth it at all. Foam costs more than loose fill, so when the attic floor just needs its gaps closed and a top-up of blown-in, the loose fill we blow through a hose, that usually wins, unless your ductwork runs up there and the roofline is where the seal belongs. I also ask about health concerns in the household before we settle on foam, because that can change the answer. Then we deal with what's underneath, pulling old insulation that's soaked or full of droppings and pointing out a roof leak or old wiring, because I'd rather you fix it than have us bury it under foam.
Open-cell lets moisture vapor pass through it, so it isn't what I'd put against damp ground, and under a house with a crawl space a crawl space vapor barrier is often the better first job. The same foam goes into shops, offices and other buildings, and our commercial insulation work covers those.
The part people worry about is the day itself, so here's how it runs from the time you leave until you're home.
Everyone who lives there, kids and pets too, needs to be out while we spray, so we pick the day together and give you time to book a place to stay. I'll tell you the re-entry time, when it's safe to come back, for the foam we're using.
Our crew masks floors, windows and fixtures and sets up ventilation before any foam goes on, because overspray is hard to get off. Anything we found at the estimate gets handled before this point.
We spray to the depth we agreed on and keep the edges as full as the middle, since thin edges are where most foam jobs fall short. Then we trim anything standing proud of the studs so drywall goes back flat.
We keep the space ventilated, sweep up and haul off the trimmings and masking. That way the house is ready for you when the re-entry time is up.
Send the form and we'll get back to you within one business day to set a time for me to come out. The on-site estimate is free and there's no pressure to book, so I'll look at the space, go over what I see and then send the written estimate for you to think over.
(806) 370-4846For framed walls, guidance written for hot, dry climates rates open-cell as the preferred choice because its insulation level is typically enough there. That same guidance says those walls must not have a vapor retarder on the inside, a layer that blocks moisture, so I check what's behind your drywall first. Closed-cell rates about R-6 an inch against open-cell's R-3.6, where R-value is how well insulation slows heat, and it stops moisture vapor, so I save it for spots where those matter more.
Consumer safety guidance says everyone living there should be out for at least 24 hours during spray foam work, so plan a place to stay for at least that long. If anyone has a history of asthma, respiratory allergies, skin conditions or a past reaction to isocyanates, a chemical family used in spray foam, that guidance says to read the product information carefully and consider other insulation if needed. That's why I ask about health at the estimate.
Across the US, open-cell spray foam for a standard 3.5-inch wall cavity usually costs about $1 to $2.50 per square foot. That's what the market charges for walls nationally, not our price, and the things I named up top decide where your house lands. Your own number comes in the written estimate after I've seen the space.
The City of Lubbock requires a permit before code-regulated building work starts, and it counts any interior change to an existing home as remodeling, but the list it gives names structural, electrical, plumbing and mechanical work, not insulation. So I won't guess whether your job needs one. When it does, we get the permit from the city where the house sits and take care of the paperwork, and if we aren't sure, we call that city's building office and ask before we start. You can ask too, since the city's Building Inspections office takes questions about specific work at 806-775-2087 or 806-775-3155.
The city also says building contractors and remodelers don't need a Texas state license, but they do have to register with that same office and show proof of commercial general liability insurance or a compliance bond, so registration is a fair thing to ask any contractor about. We do the same foam work in Wolfforth, Slaton, Levelland, Plainview, Littlefield and Brownfield, and the calls there sound a lot like Lubbock's, older houses with tired attics and rooms that never feel right.
Have the areas you want insulated, a rough square footage and any health concerns in the household handy when you call (806) 370-4846 or fill out the form, so the first conversation covers what matters.
If you're still deciding between foam and something simpler, call or send a message and I'll talk it through with you.
