Derek Bosteter has gone through the vigorous process of becoming a Vinyl Siding Institute (VSI) Certified Installer. Through the VSI Certified Installer Program, experienced professionals receive thorough training on proper, industry-approved vinyl siding installation techniques. VSI’s certification process involves classroom training and a written examination 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 two years of installation experience, attend VSI’s rigorous course, and pass the VSI Certified Installer
examination. All VSI Certified Installers must apply for recertification every three years, to ensure that they stay abreast of the latest application techniques.
