Open-cell foam insulation in Dallas TX - a sealed roof line and fewer drafts upstairs
Hot upstairs rooms and a drafty attic usually mean air is leaking in. Open-cell foam under the roof deck stops it at the roof line.

Is open-cell spray foam the right fit for your Dallas attic?
Open-cell foam insulation is a soft spray foam we apply under the roof deck or in the walls of homes in Dallas, TX. It insulates and seals air leaks in the same pass, so hot attic air stops working its way into your rooms. We're based in Dallas and work across the city and the cities around it.
Most calls start with a hot upstairs or a power bill that climbs every summer, and the first thing I figure out is whether foam is the answer or just the expensive one. The price turns on how much roof deck or wall we're covering, how thick the foam goes, how easy the attic is to get into and whether a leak or bad wiring has to be fixed first, because I won't bury either one. The schedule turns mostly on when your household can be away for the spray, and the written estimate gives you the price for your house. Landlords and property managers call us too, and we do commercial insulation for buildings full of tenants.
How do you know your attic could use open-cell foam?
Most of what tells you an attic needs work shows up downstairs first, in rooms you can't keep cool and air you can feel moving. These are the signs we hear about most.
Upstairs rooms stay hot all summer with the AC running, which usually means attic heat is getting in.
The room over the garage never feels like the rest of the house, often from air leaking around it.
Your ductwork runs through the attic, so cooled air heats up before it ever reaches your vents.
The power bill climbs every summer though nothing else changed, which often points to air leaking through the ceiling.
Dark dust streaks on the old insulation or around ceiling lights show where air has been moving through gaps.
A vaulted or cathedral ceiling heats the room below it because there's little space up there for insulation.
If you see a water stain on the roof deck, call now rather than waiting, because a leak has to be fixed before any foam goes over it.
What happens after you call us about open-cell foam?
Here's how a job runs, from your first call to the walk-through, and who you'll deal with at each step. I come out myself, and our crew does the spraying.
Call or send a request
Call (214) 706-4099 or use the form, and tell us the area you want insulated, your roof or attic type and the dates your household could be away. We get back to you to set a time for me to come look.
I look and write the estimate
I check the attic, walls or crawl space for roof leaks, bad wiring or anything else that has to be fixed before foam goes over it. You get a written estimate with the area, the foam and the price, so you know the number before anything is scheduled.
We spray on the set date
We pick the spray date with you so your household is out and has somewhere to stay, and we watch the weather because temperature and humidity affect how foam cures. Our crew sprays, trims the foam and cleans up before you come back.
We walk the job together
Once you're back in the house, I walk the finished work with you and check it before we call it done. If something doesn't look right to you, that's the time to say so.

Open-cell foam, moisture and when it's worth it
Open-cell foam stops air but lets water vapor pass through, so we plan for moisture before we spray instead of after. One federal guide says that in hot, humid climates, moisture moving through open-cell foam in frame walls has to be controlled. It also says a vapor retarder, a layer that slows moisture, on the inside can lead to condensation and mold, because air conditioning keeps the house drier inside.
Where the moisture comes from matters as much as the foam. Roof leaks get fixed first, and if the crawl space under the house stays damp, a crawl space vapor barrier usually belongs in the same plan, because foam doesn't fix a wet house.
Foam costs more than loose fill, and it earns that when the ductwork lives in the attic, because sealing the roof deck puts those ducts inside the insulation. If your ducts sit below the ceiling, sealing the gaps around lights, pipes and the hatch and then adding blown-in insulation, which is loose fill we blow through a hose, usually does the job for less. I'd rather tell you that at the estimate than sell you foam you don't need.
Open-cell foam questions from Dallas homeowners
How much does open-cell spray foam insulation cost in Dallas?
The price depends mostly on how much area we're spraying and how thick the foam goes, so I give you a number after I've seen the attic. Access, the roof shape and any repairs that have to come first also move it, and the written estimate spells all of that out.
Where can open-cell foam go in my home?
Open-cell foam can be sprayed right onto the underside of a sloped roof deck, in a sealed attic or in a cathedral ceiling. That insulates and blocks air leaks at the roof line, which is where it does the most good in an attic with ductwork in it.
How long do we have to stay out of the house after spray foam insulation?
Plan on leaving the work area before we spray and staying out for a while afterward. EPA reports that some foam makers recommend 24 hours before residents return, though the re-entry time, when you can come back, can vary. We go by the maker's guidance for the foam we use and tell you the timing before you book a place to stay.
Is open-cell spray foam safe for kids and pets?
The risk is during and right after the spray, which is why your whole household, pets included, stays out of the work area for that stretch. EPA says spray foam chemicals, including isocyanates, in vapors, mists and dust can cause asthma, lung damage and skin and eye irritation, and that exposure can happen during and after installation. We plan that time away with you as part of the job.
Who issues home building permits in Dallas?
The City of Dallas issues residential permits for construction, renovation and major repairs on a home. We check with the city's building office before we start, and when a job needs a permit, we handle the application and the inspections.
How do I check that a spray foam installer is properly trained?
Ask about the training and certification of the project manager, the installers and the helpers, which is what EPA suggests owners talk through before the job. Installers certified through the Spray Polyurethane Foam Association program carry a wallet card showing they passed its tests. We're licensed and insured, and you can ask me about our crew's training when I come out.
Related insulation work for homes and buildings
Commercial insulation
Property managers and landlords with offices or rental buildings can have us plan insulation around tenants, the way I learned it doing upkeep in occupied buildings.
Crawl space vapor barrier
A damp crawl space pushes moisture up into the house, so a vapor barrier over the dirt can belong in the same moisture plan as your foam.
