Attic Air Sealing in Allen, TX

Every gap in your attic floor — around light fixtures, plumbing, wiring, the chimney — is a hole your cooled air escapes through 24 hours a day. Dad's Home Services finds and seals those leaks in Allen homes with professional air sealing, which is the step most insulation companies skip and the reason insulation alone often underdelivers.

Air Sealing · Allen

Fix the leaks insulation can't.

Insulation is a blanket. Air sealing is the thing that stops the wind from blowing through the blanket. In a typical DFW home, the cumulative gaps in the attic floor add up to a hole the size of an open window. Sealing them is one day of work with a measurable result.

Find every leak

Can lights, plumbing stacks, wire penetrations, top plates, attic hatch, chimney chase — we check them all.

Seal with the right material

Fire-rated foam and caulk where required, weatherstripping at the hatch, proper covers over can lights.

Before/after photos

You'll see every gap we found and every gap we sealed.

Signs your attic needs air sealing

  • Drafts near ceiling fixtures or the attic access
  • Dust streaks on insulation around can lights or wires
  • Rooms under the attic are hard to keep comfortable
  • Humidity feels high indoors in summer
  • Pest or insect activity near ceiling penetrations
  • You've added insulation and still have hot rooms

Why Allen homes leak more

  • DFW's long cooling season means attic leaks cost you money for 7+ months a year
  • Humidity pushed into the attic through leaks is a leading cause of mold on the roof deck
  • Many Allen homes have dozens of recessed can lights — each one is a leak unless it's sealed
  • Air sealing before adding insulation makes the insulation work dramatically better
  • This is the step most 'insulation only' companies skip — it's why we always inspect first

Questions Allen homeowners ask

Is air sealing the same as insulation?
No. Insulation slows heat transfer; air sealing stops airflow. Most DFW attics need both, and sealing should come first.
Will it make my house too tight?
Not with attic sealing alone — your home still breathes through normal ventilation. We're closing the big accidental leaks, not making the house airtight.
How long does it take?
Most attics are sealed in half a day to a day, depending on size and the number of penetrations.
Can you seal and insulate in the same visit?
Yes, and that's what we recommend. One visit, both done, insulation blown over a sealed floor.
