It provides an assurance that certified installers have been trained and passed the written examination.

How does a contractor become a certified installer?

The training covers:

- Product care, adjustment, cleaning, and much more
The candidates must then apply what they have learned to pass a thorough written examination. Once the installers pass the exam, they become InstallationMasters™ installers.
Hiring an InstallationMasters™ No matter how much you spend on top of the line windows and doors, they won’t achieve peak performance if they are installed incorrectly. There is a lot to know about properly installing windows and doors. Window manufacturers’ installation instructions can’t be expected to provide complete details on how to handle the hundreds of different surrounding wall and job site conditions found in the field. Mistakes during installation may result in:
- The loss of energy savings you were counting on from a high-performance product
- The frustration of repeated service calls to correct problems with air and water leakage, and improper installation.
- Significant damage to your home from water damage and mold growth
To confirm your window installer or contractor has been trained and certified, ask to see his or her official InstallationMasters™ photo identification card.
