Request an estimateDoes my attic need air sealing before more insulation?
Attic air sealing closes the holes and gaps in your attic floor, the layer between the attic and the rooms below, and in Fort Worth it's the step that should come before any new insulation. Done well, it cuts the energy your house loses, lowers the power bill and helps keep moisture problems out of the attic.
Most calls start with a hot upstairs, a room over the garage that never cools off, or a power bill that keeps climbing even after insulation was added. Often the insulation isn't the problem. The air moving through the gaps under it is, and sealing first is what makes new attic insulation worth paying for. The price moves with the size of your attic, how easy it is to get around in, how many openings need sealing and how much insulation is in the way. The schedule mostly turns on whether I find something that has to be fixed first, like a roof leak or insulation that needs testing, and I'll give you your own number when I come out to look.
How we handle attic air sealing
Before I seal anything, I go up and check for the things that stop the job, like live old wiring, a roof leak, a bath fan venting into the attic or insulation that may be vermiculite. If I find one, it gets dealt with first, because sealing over a wet roof deck or a fan pushing steam into the attic just traps the problem. Then we seal the spots where air moves between your rooms and the attic: around can lights, plumbing and wiring holes, the tops of interior walls and the attic hatch, which is the one people forget. We stay on the joists the whole time so nobody steps on your ceiling, and once the leaks are closed, the attic is ready for insulation with the eave vents left clear so it can still breathe.
Most attics we seal get topped up afterward with blown-in insulation, which is loose fill blown through a hose. If your walls or floors are thin too, that's retrofit insulation, adding insulation to a house that's already built. Spray foam insulation seals and insulates in one pass, but it costs more, so I usually recommend sealing the gaps and adding loose fill unless your ductwork runs through the attic, where foam starts to earn its price.
What attic air sealing deals with in Fort Worth
Tarrant County sits in the hot-humid climate zone, so the moisture side of air sealing matters here as much as the power bill does. One DFW insulation company reports that attics around here can pass 140 degrees in summer, and every unsealed gap in the ceiling is a path between that attic and your rooms. Sealing those gaps keeps your cooled air downstairs and helps keep moisture from building up in the attic. On jobs in Haltom City and North Richland Hills we find the same leaks we find in Fort Worth, around can lights, bath fans and the hatch, and we handle them the same way.
Texas lets each city and county make its own changes to the energy code, so what a job needs can differ from one city to the next. Before the work starts, we check with that city's building office about what your job needs and take care of any permit and inspection on our end.
Why call us for attic sealing
I come out and look myself
I do the estimate visit in person, and I run the work alongside our install crew. The person who found the problems in your attic is the one making sure they get fixed in the right order.
In business since 2020
I left an office job to learn insulation on a Fort Worth crew and started this business in 2020. Six years in, the prep is still what we're known for, because insulation laid over a leak won't do much for you.

Frequently asked questions
What is the best order for air sealing and insulating an attic?
Sealing comes first, then insulation, because once new insulation is down the gaps under it are buried and much harder to reach. That's the standard order for getting the most energy savings out of both, and if you're adding insulation to an attic with roof vents, plan the sealing as the first step of that project. A roof leak or old live wiring comes before either one.
Is it safe to air seal an attic if I have a gas water heater or furnace?
It can be, once those appliances are checked, because a tighter house changes how air moves around a furnace or water heater. Air sealing guidance says furnaces, water heaters or boilers on a natural draft chimney, the kind that relies on rising heat to carry exhaust out, need combustion air brought straight in from outside, and it calls for a backdrafting test, which checks that exhaust goes up the flue and not into your house. Ask whether that test is part of the job, and tell me about those appliances when you call.
What happens if my attic has vermiculite insulation?
The sealing waits until it's been tested, because vermiculite may contain asbestos and the guidance says to test it before the attic is sealed and insulated. It usually looks like light, pebbly, gray-brown fill. The guidance points owners to the state health department for testing, and once you have the result, we can plan the rest of the job.
Will the crew have to move my existing attic insulation?
Yes, where it's covering the gaps, because you can't seal what you can't reach. Removing existing insulation as needed is the standard step for this, and we pull it back only as far as the work needs. If what's up there is soaked or full of droppings, it should come out instead of going back, which is insulation removal.
How much does attic air sealing cost in Fort Worth?
I price it after I've been in your attic, because the cost comes down to what's up there. The size of the attic, how much headroom we have, how many can lights, pipe holes and wall tops need sealing, and any flue that needs metal work around it all move the number. Anything that has to be fixed first, like a roof leak, adds to the job, and I'll tell you that up front.
How do I know if attic air sealing actually worked?
You'll usually notice it in the rooms first, with less draft upstairs and a house that holds its temperature better. How well an air barrier works is measured across the whole house, not one gap at a time, so ask any contractor you're talking to how they'll check the result. I'm glad to talk that through with you at the estimate.
Related insulation work
Retrofit insulation
If your walls or floors were built thin, retrofit insulation adds coverage to the finished house without tearing it apart, and it pairs well with an attic we've just sealed.
Spray foam insulation
When your ductwork runs through a hot attic, spray foam can seal and insulate at once, which costs more but keeps the ducts out of the worst of the heat.
