Professional Air Sealing Solutions

Stop the Hidden Energy Thief in Your Arizona Home

The Foundation of Energy Efficiency

Air leakage accounts for 25-40% of heating and cooling energy loss in typical Arizona homes. Before adding insulation, proper air sealing creates the envelope your home needs to maintain comfortable temperatures and reduce energy bills. Our comprehensive air sealing services use professional-grade materials to eliminate drafts, hot spots, and energy waste.

💨 40% of Your Energy May Be Escaping

The average Arizona home has enough air leaks to equal leaving a window open year-round. In our extreme climate, that means your AC works overtime to cool air that immediately escapes.

Understanding Air Infiltration

Air infiltration occurs when outside air enters your home through cracks, gaps, and penetrations. In Arizona's climate, this means:

  • 120°F+ air entering during summer days
  • Conditioned air escaping 24/7
  • Dust and allergens infiltrating living spaces
  • Moisture entering during monsoon season
  • HVAC systems running constantly to compensate

Common Air Leak Locations

🏠 Attic (40% of leaks)

  • Attic hatch or pull-down stairs
  • Recessed light fixtures
  • Plumbing and electrical penetrations

The Air Sealing Process

1

Blower Door Testing

We use professional equipment to measure your home's air leakage rate and identify problem areas. This scientific approach ensures we address the most critical leaks first.

2

Infrared Scanning

Thermal imaging reveals hidden air leaks that are invisible to the naked eye, especially around electrical boxes, plumbing penetrations, and structural connections.

3

Systematic Sealing

Starting from the attic down, we seal all identified penetrations using the appropriate materials for each application, ensuring long-lasting results.

4

Verification Testing

Post-sealing blower door test confirms improvement and ensures we've achieved optimal air tightness without over-sealing.

Arizona-Specific Challenges

🌡️ Extreme Temperature Differentials

With outside temperatures reaching 120°F and inside temperatures at 75°F, even small leaks create significant energy loss. Materials must withstand extreme expansion and contraction cycles.

🌪️ Dust Infiltration

Arizona's dust storms and fine particulates require thorough sealing to maintain indoor air quality. Proper air sealing reduces dust accumulation by up to 70%.

🦂 Pest Entry Prevention

Air sealing also blocks entry points for scorpions, spiders, and other desert pests. We use pest-resistant materials in all applications.

💧 Monsoon Moisture

While rare, Arizona's intense monsoon rains can drive water through the smallest gaps. Proper sealing prevents water damage and mold growth.

Investment & Savings

DIY vs Professional Air Sealing

What Homeowners Can Do:

  • Apply weatherstripping to doors and windows
  • Caulk visible gaps around window frames
  • Install door sweeps
  • Add outlet gaskets

Why Professional Service Matters:

  • Blower door testing identifies hidden leaks
  • Proper material selection for each application
  • Safe access to attic and crawl spaces
  • Warranty on materials and workmanship
  • Compliance with building codes
  • Integration with insulation improvements

⚠️ Important Considerations

  • Homes need some air exchange for health and safety
  • Over-sealing can cause moisture and air quality issues
  • Combustion appliances require adequate ventilation
  • Professional testing ensures proper balance

Frequently Asked Questions

How do I know if my home needs air sealing?

Common signs include: high energy bills, rooms that won't stay comfortable, excessive dust, drafts near windows/doors, and ice dams in winter (for Northern Arizona homes).

Can air sealing be done after insulation?

While possible, it's much more effective and economical to air seal before adding insulation. We recommend addressing air leaks first for maximum efficiency.

How long does professional air sealing take?

Most homes can be professionally air sealed in 1-2 days, depending on size and number of penetrations. Testing adds 2-3 hours to the process.
