National Construction Self-Supported Ministry has been a pioneer protecting, conserving water usage. In the construction industry, the number one cause of loss is due to water infiltration. It is for this reason National Construction Company made the proactive investment of an in-house Building Envelope Specialist. Focusing on minute details that can contribute to water intrusion, we bring a practical depth of experience to support the project team and complement any third-party consultant that may be engaged. In addition, our one-year warranty walk allows us to check the performance of the building one year later, before system and component warranties end.
