Protecting the investment represented by a building is a concern of many property owners. An energy performance test is designed to measure how airtight a building is to diagnose comfort, indoor air quality and durability issues. For new construction or existing structures, we pressurize and depressurize the building to quantify the air barrier leakage. Using industry best practices and following ASTM or Army Corp of Engineer requirements as required, we estimate the value of energy lost to air infiltration and offer you options to resolve. Learn About Air Infiltration Testing also know as air barrier testing.


Using infrared technology, blower doors, and visual indicators, we identify the holes that exist in a building's air barrier. Once identified, we patch or otherwise fill those gaps to improve the energy efficiency of the building, creating a comfortable, safer, more durable and energy efficient place to work and live. Learn How We Can Improve Your Building Performance.


For Architects and Building Engineers who require review and documentation from an air barrier specialist during the planning phase of a new construction or a retrofit project, we offer consultation and reporting nation-wide. No matter what industry or building-type, we are ready to support your due diligence.


Depending on the age and construction of your building, you may see dramatic improvement in energy costs and occupant comfort with proper insulation.  Although we rarely suggest it as the first course of action for decreasing energy consumption, we will offer the service when  we see the condition of a building during the air sealing process.  Find out if insulation is the right step for you.
