Sealing the unintended leaks in the building envelope is the first step in improving performance: air quality, energy efficiency, and moisture management.
This component includes the following tasks:
- Using a blower door, identify major building penetrations using a blower door to increase the relative pressure between the house and the outside so that we can identify major points of infiltration.
- Seal the previously identified penetrations using caulk, mastic, expanding foam, or weather- stripping.
- Seal leaks around supply air registers and returns.
- Seal plumbing and utility penetrations.
- Survey the duct connections, remove tape to expose connections, and seal leaks with mastic.
- If needed use thermographic imaging to detail problem areas.
