PA IECC Code Compliance Testing

Blower door tests, and duct leakage diagnostics are the foundation of effective home performance mandated by Pennsylvania.

Use this section to reach out if you're interested in:

↳Blower door testing for envelope leakage reporting per 2018 IECC code and compliance
↳ Duct leakage pressure testing and quantification reporting per 2018 PA~IECC


→ Our testing and reporting have helped hundreds of builders and homeowners meet code, close on time, and receive certificates of occupancy. If you're looking to verify envelope or duct leakage, we can help your project meet Pennsylvania's building performance standards with confidence.

Diagnostics & Testing

Home energy assessments, blower door tests, and duct leakage diagnostics are the foundation of effective home performance upgrades.

Use this section to reach out if you're interested in:

↳Comprehensive energy audits
↳Blower door testing for envelope leakage or code compliance
↳ Duct leakage testing and quantification for forced-air systems


→ Structured diagnostics allow us to identify the real issues — whether it's air loss, duct inefficiency, or pressure imbalances — before recommending solutions.

Air Sealing & Insulation

Air sealing and insulation are critical to controlling heat flow, air movement, and moisture throughout your home.

Use this section to reach out if you're interested in:

↳ Home, attic, or crawl space air sealing
↳ Aeroseal duct sealing
↳ Insulation upgrades (attic, wall, or floor)
↳ Insulation removal due to damage or contamination

→  Air sealing and insulation work together to lock in comfort and block out uncontrolled airflow. Guided by testing, we target gaps in the envelope and hidden pathways that undermine performance — The result is a home that feels quieter, cleaner, and more consistent year-round.

Specialized Services

Some upgrades go beyond sealing and insulation — but are just as essential to whole-home performance.

Use this section to reach out if you're interested in:

↳ Aeroseal duct sealing to stop hidden duct losses and restore airflow balance
↳ Heat pump water heater installations for high-efficiency electric hot water
↳ Indoor air quality solutions including ventilation, filtration, and comfort control strategies


→ These specialized services are offered when deeper performance, efficiency, or air quality goals call for a more targeted solution — all based on diagnostic findings and building science principles.
