Cold floors, a drafty rim joist or a hot room over the garage? We seal those tight spots and insulate them with dense foam.
Closed-cell foam insulation is a dense spray foam that stops drafts and insulates in the same layer. At Airlock Lubbock Spray Foam Insulation, we install it in homes and commercial buildings across Lubbock, TX and the cities around it.
Most folks who call me about it have cold floors over a crawl space, a drafty room over the garage, or air coming in along the rim joist, the band of framing that sits on the foundation under your walls. At its usual thickness, closed-cell foam is rigid and works as a vapor retarder, so moisture vapor can hardly get through it. It won't soak up water either, which makes it a good fit for the damp, cramped spots where other insulation has a hard time.
The price turns mostly on how many square feet we cover, how thick the foam goes, how hard the space is to reach, and whether wet or dirty insulation has to come out first. The schedule turns on finding a day your family can be out of the house. If the job also adds a circuit, changes ductwork or comes with an addition, it turns on the city's permit too. I put all of it in a written estimate after I've looked at the space, so you see your own figure before you decide.
Every job runs the same way, so you'll know who's at your house at each step and what you're agreeing to before anyone sprays anything.
I look at your rim joists, crawl space, attic or walls in person and talk through what I find, including any roof leak or old wiring that should be fixed before anything gets covered up. I started out as a helper on a Lubbock insulation crew and opened this business in 2021, so I've been running it for five years now.
After the visit, I send a written estimate that lists each space, the foam for it and the prep it needs. Before the crew comes, I go over the safety steps we've planned for your house, and you're welcome to ask me the same question twice.
We're licensed and insured, and the people working in your house are our own crew. When they're done, I walk the finished job with you so you can see what we did. Satisfaction guaranteed on every job.
Closed-cell does its best work in tight spots like rim joists, but it isn't the right call for every wall. So I start by comparing it with open-cell for each part of your space and going over the cost difference before you choose. At a rim joist, a much thinner layer of closed-cell than open-cell is enough to stop air, so one layer seals and insulates that spot in a single step. Once you've picked where each foam goes, the day itself runs in the four steps below.
Where your walls or roof deck call for a softer, less costly foam, we install open-cell foam insulation, and plenty of houses end up with some of both. Business owners with a shop, office or metal building can read about our commercial insulation work, since we spray closed-cell in those buildings too.
Once you've picked a date and made plans to be away, this is what our crew does from start to finish.
We cover floors, fixtures and anything nearby that we aren't spraying, and we set up fans to move air out of the work area. Spray foam sticks to whatever it lands on, so we take our time with this part.
If old insulation is wet or full of droppings, we take it out first, because foam sprayed over it just seals the problem in. We also brush off dust so the foam bonds to clean wood.
We spray closed-cell in passes instead of one heavy coat, following the foam maker's instructions on how thick each pass can go. That keeps the coverage even out to the edges, instead of thick in the middle and thin at the corners.
We keep the space ventilated while the foam cures, trim anything that bulges past the framing and haul off the scraps. The questions below cover when you can come back.
Send the form or call (806) 370-4846, and we'll get back to you within one business day. I'll come out for a free on-site look, talk through what I find and then send a written estimate, with no obligation and no pressure to book. If you can, note the rough square footage and any ductwork, electrical work or addition you're planning.
(806) 370-4846Across the US, installed closed-cell spray foam at standard wall thickness usually costs about $3 to $5 per square foot. That's a national figure, not our price. Your number depends on the square footage, thickness and prep mentioned above, so I measure on site and put it in your written estimate.
Safety guidance for spray foam says to stay out of the house while the work is going on and for at least 24 hours afterward. That goes for the kids and pets too, so book a place to stay and we'll set the job date around it.
Check before you book, because spray foam isn't the right fit for everyone. Safety guidance says people with skin conditions, respiratory allergies, asthma or a past sensitivity to isocyanates, chemicals used to make the foam, should read the product information closely and consider other insulation if needed. I'll get you the product information for the foam we'd use, and if it isn't a good fit, we'll talk about other options.
For framed walls in a hot-dry climate, one building guide rates open-cell as the preferred choice because the insulation it gives is typically enough there. The guide explains that a small gap between indoor and outdoor temperatures asks less of a wall, so both foams are worth comparing before you pay for closed-cell. I look at your walls and what's inside them before I recommend either one.
Lubbock's Building Safety Department issues permits for structural, electrical, plumbing and mechanical changes. Its list names windows, walls, circuits, plumbing and ductwork but not insulation, so ask about a foam-only job rather than assume either way. When a job needs a permit, like one that adds a circuit or changes ductwork, we get it from the city and take care of the paperwork. If we aren't sure, we call the department before we start. You can ask your own questions on its residential line at 806-775-2087, Monday to Friday, and request a Residential Plans Examiner.
In Lubbock, anything attached to an existing house counts as an addition no matter how small it is, and it needs a permit with plan review under the codes the city has adopted, including the International Residential Code and an energy code. The contractor on a new home or an addition has to be registered with the department, so ask about that before you hire. We do the same foam work in Wolfforth, Slaton, Levelland, Plainview, Littlefield and Brownfield, where most closed-cell calls are for rim joists, rooms over garages and shop buildings, and we check with each city's building office the same way.
Call (806) 370-4846 or use our contact form before any drywall or ductwork work starts, because foam is easiest to spray while the framing is still open.
If you're still weighing closed-cell against open-cell, call (806) 370-4846 and I'll walk you through it.
