We have recently upgraded our Request For Service management system. William Lyon Homes along with SiteOne Services, have created a homeowner specific web-site where you can manage the Warranty requests for your home.
Utilizing your SiteOne homeowner web-site you can:
New homeowners will receive an email from one of your Warranty Coordinators containing your new SiteOne Username and Password, along with other information about SiteOne. If you are an existing homeowner and do not currently have a username and password for SiteOne, please call the Warranty Service Department for your area and one of our Coordinators will help you with the process. The phone numbers for the Warranty office in your area are listed on the "Contact Us" page that may be accessed above.
