Attic insulation (blown-in, spray foam and radiant barrier) for Dallas–Fort Worth homes that run hot upstairs in August or cold in a freeze. A well-insulated house holds its temperature instead of chasing it, and the bill drops as a side effect.
Attic insulation slows the movement of heat between the roof and the rooms below, and in North Texas the summer sun is what it has to fight. The right type depends on the attic you already have. Blown-in insulation adds depth over the attic floor, spray foam also seals gaps and leaks, and a radiant barrier reflects heat coming off the underside of the roof.
Start with a look at what is up there now: how deep the old insulation is, whether it is wet or matted, and whether air is leaking around lights, ducts or the attic access. Insulation over a leak or a gap does less than you would expect, so sealing often comes first. Older houses with thin or settled insulation usually have the most to gain, and a recently insulated attic may not need more.
Most DFW attics are under-insulated for the climate. We’ll get up there, tell you what’s actually in place, and recommend the approach that pays back fastest for your house.
Highest Performance
Expanding foam that seals as it insulates, getting into the gaps and penetrations that batts simply bridge over. The strongest option where air leakage is the real problem.
Best Coverage
Loose-fill blown across the attic floor to an even, consistent depth. The most practical way to top up an attic that was under-insulated when the house was built.
Texas Specific
A reflective layer applied to the underside of the roof deck. It pushes radiant heat back out before it ever loads into the attic. That matters a lot in a North Texas summer.
| Option | What it does | Best when |
|---|---|---|
| Spray foam | Seals air leaks and insulates in one application, reaching gaps that batts bridge over | Air leakage is the real problem, or ductwork in the attic runs hot |
| Blow-in | Loose fill spread across the attic floor to an even depth | The attic is simply short of insulation, which describes most DFW attics |
| Radiant barrier | A reflective layer under the roof deck that pushes radiant heat back out | The attic runs hot all summer; it works alongside existing insulation, not instead of it |
We get into the attic, look at what is up there, check the depth and coverage, and price the work to reach the level you want.
Baffles, air sealing and protection for the run of the house go in first, so the insulation performs and the rest of the house stays clean.
Material goes in to an even, measured depth across the whole attic floor or roof deck, not just where it is easy to reach.
We show you the finished depth and coverage, leave a note of what was installed where, and back the work.
Spray foam seals air leaks as it insulates, so it’s best when the attic is leaky. Blow-in is the practical way to top up an under-insulated attic. We’ll tell you which one pays back faster for your house.
Most DFW attics are under-insulated for the climate. Bringing them up to standard usually shows up on the very next summer bill, and the house holds temperature more evenly.
Attic work happens above you. It takes a day or less for most homes, with minimal disruption inside.
Plan to be out while the foam is applied and while it cures. We’ll tell you the timing for your job before we start.
We go up and look for where air is getting through: gaps around top plates, open chases, recessed lights, the hatch, and daylight at the eaves. We also note where the ducts and air handler sit and how the attic is vented, because foam on the roof deck changes how the attic works. We’ll show you photos of what we found.
When foam goes on the underside of the roof deck, the attic is usually treated as a sealed space rather than a vented one, so the vents are closed off as part of the job. That is a change to how the house works, which is why we look at the HVAC and roof before recommending it.
