How much is the hourly rate for a vinyl installer?

Hourly rate varies greatly and depends on experience. Another variable is whether the installer is working for cash or if you hire an actual business. For a cash installer with significant experience you can expect to pay $25/hr. If you are hiring a business, expect to pay $2.25/ft or more. Typically a business will bid by the job and not by the hour, so don't expect an itemized list. You typically get what you pay for.
