In Arizona, your attic can reach temperatures above 150 degrees on a summer afternoon. If there are unsealed gaps between your attic and living space, that extreme heat is constantly pushing into your home. Your AC runs harder, your rooms stay uneven, and your energy bills stay high.
Air sealing is the step that most insulation jobs skip. It involves going into the attic and physically sealing every penetration where conditioned air escapes or hot air enters. Can lights, top plates, plumbing stacks, duct boots, electrical runs, and recessed fixtures are all common entry points. When those are sealed properly, your insulation actually performs the way it should.
At Foam Pro Insulation, air sealing is a dedicated service we perform after insulation removal and before any new insulation is installed. That sequence matters, and we do not cut corners on it.
These problems usually point back to unsealed attic penetrations. If any of these sound familiar, a free attic inspection is the right first step.
Hot air from the attic migrates into living spaces through unsealed gaps near can lights and top plates.
Your AC works overtime compensating for heat gain caused by air bypasses that insulation alone cannot stop.
Attic air carries particles, allergens, and debris into your home through the same penetrations that leak heat.
An HVAC system under thermal stress wears out faster. Air sealing directly reduces the load on your unit.
Insulation cannot reach its rated R-value if air is bypassing it through gaps below and around it.
Auditors commonly find attic air leakage as one of the top drivers of energy loss in Phoenix-area homes.
During an air sealing service, our crew goes through the attic and addresses every connection point between your attic floor and your living space. Here is what we typically seal:
We use professional-grade can foam and compatible sealants selected for the Arizona climate. Every penetration is addressed before any new insulation goes down on top.
We follow a clear sequence for every attic retrofit job. Rushing or skipping steps leads to insulation that underperforms from day one.
We start with a no-cost inspection of your attic. We check existing insulation depth, look for signs of contamination or damage, and use thermal readings to identify where air is moving and where the biggest bypasses are. You get a clear picture of what is going on before any work starts.
Air sealing is only performed after removal. If your existing insulation is contaminated, damaged, or needs to come out for a full retrofit, we handle that first at $1.20 per square foot. Removing old material gives us clear access to every penetration on the attic floor.
With the attic floor accessible, our crew works through every penetration systematically. Can lights, plumbing, electrical runs, top plates, duct boots. Each one is sealed with foam or compatible sealant before we move on. No rush, no skipped spots.
Once air sealing is complete, we install blown fiberglass insulation to the depth and R-value your attic needs. Most Scottsdale homes benefit from R-38 to R-49 depending on existing conditions. We use Knauf insulation and document depth with photos before we leave.
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.
We believe you should know exactly what you're paying for—before any work begins.
That's why Foam Pro publishes straightforward pricing for our core services:
Important Pricing Note: All estimates assume full attic access. Final pricing is confirmed during your free in-person inspection—because every home is different, and we won't quote work we haven't seen.
