Your home deserves the best! If you are re-siding your home or building a new one, the quality of the installation should be as good as the vinyl siding you chose. Make sure it's done by a VSI Certified Installer or Certified Installer Company. The VSI Certified Installer Program is coordinated by a third-party administrator, Architectural Testing, Inc., which registers participants, reviews tests, trains trainers, and verifies company quality control programs.

Through the Vinyl Siding Institute’s(VSI’s) Certified Installer Program, experienced professionals receive thorough training on proper, industry-approved vinyl siding installation techniques. VSI’s certification process involves a combination of classroom training, hands-on instruction, and a written test given by a VSI Certified Trainer.
Each VSI Certified Installer must demonstrate the knowledge and skills to properly
install vinyl siding and accessories, based on the industry standard, ASTM D4756.
When you hire an installer certified through VSI’s program, you can be confident that he or she knows how to:
• Correctly fasten the siding to allow for vinyl’s normal expansion and contraction
properties and keep it straight and secure on the wall.
• Properly prepare the area around doors, windows, and other openings to prevent water infiltration.
• Pay attention to the details that will give your home a beautiful appearance that
will last over time.
To become a VSI Certified Installer, candidates must have a minimum of one year of
experience installing vinyl siding and accessories, attend VSI’s rigorous course, and pass the VSI Certified Installer exam (or have three years of experience and pass the VSI Certified Installer exam). All VSI Certified Installers must apply for recertification every three years, to ensure that they stay abreast of the latest application techniques.
