Introduced in 2005, the VSI Certified Installer Program has enabled experienced professionals to receive training on proper, industry-approved vinyl siding installation techniques. The program has been a resounding success as VSI's Official Registry of Certified Installers now includes more than 4,000 Certified Installers.

These installers have taken advantage of the many benefits of certification:

Independent validation of their skills and knowledge Improved credibility as a qualified professional installer Higher quality work requiring fewer call-backs Increased exposure through VSI's Official Registry of Certified Installers

The VSI Certified Installer Program, with three distinct types of certification: Certified Installer, Certified Trainer and Certified Installer Company, continues to gain momentum as more and more builders and homeowners learn the quality of the installation is just as important as choosing a high quality product. Certified Installers and Certified Installer Companies know that their status gives them a substantial competitive advantage.

In order to receive certification, experienced installation professionals undergo a rigorous course of study and examination on properly installing vinyl siding, soffit and accessories, based on the vinyl siding installation standard ASTM D4756.

In conjunction with the VSI Product Certification Program, Certified Installers and Certified Installer Companies are assuring vinyl siding and accessories will look great and perform well for years to come.
