Guaranteed Pass Program
Our Guaranteed Pass program applies to all residential blower door and duct leakage tests. When an issue results in a score that does not meet the Minnesota Building Code, we help our clients to find the source of the air leakage and retest at no charge.
Our Guarantee To You.
When a home does not pass a blower door test there is a reason. The reason is that the building envelope has one or more areas that are open to the outside. To put it simply, when a vacuum is applied inside the building envelope the air is leaking into the home.
The USA recognised the importance and benefits of Blower Door Testing and made it a part of the Building Code in 2015. Insulating a home is only one factor. It is necessary to confirm the integrity of the building envelope.

Blower Door Science
The Blower Door Test is based on science. The result of this scientific test is to quantify the amount of leakage in a home's building envelope.
This leakage becomes quantifiable when a known amount of vacuum is applied.
The system that comprises the Blower Door has three basic components. The first component is the Blower Door itself. This part of the system consists of a frame and a non air permeable cloth cover.The cloth cover creates a barrier between the area to be tested and the outdoors. The area to be tested is under vacuum during the test. As a consequence of this, the Blower Door Cloth will be pressed inward. The non air permeable cloth cover is held in place by an adjustable frame. This adjustable Blower Door Frame performs two functions. The first is that the frame holds the Blower Door Cloth. The second function is that the adjustable Blower Door Frame secures the the unit in the door frame of the home.
The Blower Door Fan is located in the lower part of the Blower Door Frame. The Blower Door Fan creates the vacuum under which the Blower Door Test is performed. Inside of the Blower Door Fan there are an array of sensors. These measure the air velocity and the volume of the air which passes through the Blower Door Fan. These measurements are sent to the Blower Door Gauge. The gauge then processes the measurement data obtained from the fan sensors. It is in this way that an accurate and quantifiable measurement of a home's leakage can be determined.
