Air Sealing Phoenix - Seal the Hidden Gaps Draining Your Comfort and Your Wallet

Professional attic air sealing that stops energy loss at the source. Phoenix homeowners trust Foam Pro to fix what insulation alone can't.

Why Your Insulation Isn't Enough—And What's Really Costing You Money

You’ve got insulation in your attic. So why does your upstairs still feel like an oven in July? Why do your energy bills keep climbing even after you cranked down the thermostat?

Here’s what most Phoenix homeowners don’t realize: insulation slows heat transfer, but it doesn’t stop air movement. Every gap around your recessed lights, electrical wires, plumbing stacks, and duct boots is a direct pathway for conditioned air to escape—and for superheated attic air to infiltrate your living space.

These hidden penetrations can account for up to 30% of your home’s energy loss. And no amount of additional insulation will fix them. That’s where professional air sealing comes in.

Foam Pro Insulation specializes in identifying and sealing these critical bypasses before insulation is installed or upgraded—because we’ve learned that doing the job right the first time is the only way to deliver real, lasting comfort.

What Is Air Sealing—And Why Does It Matter in Arizona?

Air sealing is the process of manually closing gaps and cracks in your home’s building envelope—specifically, the boundary between your conditioned living space and your unconditioned attic. Using professional-grade expanding foam and sealants, our technicians target every penetration point where air can escape or enter.

Common air sealing targets in Phoenix attics include:

  • Top Plates

    The framing connection between walls and attic flooring.

  • Recessed (Can) Lights

    Major culprits for heat gain and air loss.

  • Electrical And Plumbing Penetrations

    Wires, pipes, and conduit that punch through the attic floor.

  • Duct Boots And Connections

    Where your HVAC system meets the attic space.

  • Attic Hatches And Access Points

    Often overlooked but highly leaky.

In Arizona’s extreme climate, these small openings have outsized impacts. When your attic reaches 150°F+ in summer, even minor gaps become highways for heat infiltration. Proper air sealing creates a true thermal boundary—allowing your insulation and HVAC system to work as designed.

The Department of Energy and ENERGY STAR® consistently recommend pairing air sealing with insulation upgrades for maximum energy performance. In fact, SRP’s insulation rebate program requires air sealing to qualify for up to $600 back.

Our Air Sealing Process: Done Right, Done Once

At Foam Pro Insulation, we don't treat air sealing as an afterthought—we treat it as a foundational step that determines whether your entire attic system performs as promised.

Step 1: Comprehensive Attic Inspection (FREE)
  • Before we quote any work, our technicians conduct a full visual assessment of your attic. We document existing insulation levels, identify contamination or damage, locate all penetrations, and use thermal readings to pinpoint problem areas. This inspection is always free—because you deserve to know exactly what you're dealing with.

Step 2: Insulation Removal (When Required)
  • Air sealing can only be done properly on a clean attic floor. If your existing insulation is covering the penetrations we need to seal—or if it's contaminated by rodents, moisture, or age—we remove it first. Our insulation removal service runs $1.20/sqft and ensures we can access every gap and crack.

Step 3: Manual Air Sealing
  • With the attic floor exposed, our technicians systematically seal all identified bypasses using professional-grade expanding foam and appropriate sealants. We work methodically from one end of the attic to the other, ensuring nothing is missed.

Step 4: New Insulation Installation
  • Once sealed, your attic is ready for properly installed insulation that will actually perform. We recommend blown-in fiberglass to R-38 or R-49 depending on your goals and existing conditions.

Important:
We only perform air sealing after insulation removal. This isn't arbitrary—it's the only way to guarantee thorough, effective work. Sealing on top of existing insulation means missing critical bypasses and wasting your money.
