Why Attic Spray Foam & Air Sealing Comes First
Attic spray foam and air sealing go after the space that does the most damage in a North Texas summer. An attic above a typical Arlington home can get far hotter than the outdoor air, and every gap in the ceiling lets some of that heat and dust into the rooms below. Air conditioning lost through the same gaps is paid for twice. Sealing first, then insulating, is the order that works.
Two ways to handle an attic
The first is to keep the attic vented and outside the house: seal the ceiling plane at lights, fans, chases, plumbing, wiring holes, top plates and the hatch, then add insulation on the floor to depth. The second is to make the attic part of the house by spraying open-cell foam on the underside of the roof deck and the gable walls and closing the vents. That second approach makes the most sense when the ducts and air handler live in the attic, because they then sit in a much cooler space.
What the numbers say
The Texas residential energy code calls for R-38 in ceilings in climate zone 3. ENERGY STAR recommends R-49 for an attic with no insulation and R-38 added on top of 3 to 4 inches of existing insulation. Many older attics in the Mid-Cities fall short of that because loose fill has settled or been pushed aside by storage and service work.
Signs your attic needs work
Hot second floors, ceilings that feel warm to the touch in the afternoon, dust streaks at the edges of carpet, a hatch you can feel heat around, or ducts that sweat. We measure the depth, look at the ducts and vents, and recommend the approach that fits. Get a free estimate

Attic Spray Foam & Air Sealing Questions
Do I need permits for attic insulation in Arlington?
Insulation alone usually does not, but HVAC, electrical and re-roofing work do under the City of Arlington's permit list. If your project changes ducts or the roof, those parts follow the permit process.
Does a sealed attic need ventilation?
A sealed attic is designed without roof vents, but it still needs a plan for humidity, usually some conditioned air or a dehumidification approach. We explain the details for your house.
Can you air seal without adding insulation?
Yes, but most attics benefit from both. Sealing stops airflow, and insulation slows the heat that still conducts through the ceiling.
How long does an attic job take?
Many single-family attics take a day. Larger homes, removal or roof deck foam can add time.
