In lieu of creating a webform from scratch, you can also use an existing webform as a template (if the Node Clone module/feature is installed and enabled on your site; for sites with more complex webforms than a standard contact form, this feature is generally enabled).  Cloning of the webform will copy all content and form settings.

Visit the actual page/form on the site.  Click the “CLONE CONTENT” listed by the content management/edit tabs (either at the top of the page or the bottom).  

This will open the content entry form page for the new copy of the webform.
