Some people do install vinyl siding themselves, but it's a pretty big job.
Typically, it can take three professional installers up to two days to install vinyl siding on an average size home. Before you decide to do it yourself, consider the time involved, how much help you'll have and your level of experience. These are the reasons people often choose a professional contractor for worry-free installation. Professional installation is the key to an attractive exterior that won't warp or buckle over time. The cost of professional installation will be quickly offset by the savings of never having to paint or maintain your siding again.
