Quality Assurance

Building Quality Homes Designed for the Northwest

For more than 20 years, Polygon Northwest has been building homes that endure our wild La Niña rains, Thanksgiving windstorms, and unforeseen winter blizzards. Our exclusive foundation-to-roof Weather-tight Checklist covers all five critical 'weather mitigation' construction stages—roofing, papering and flashing, insulating, siding and exterior finishing. The framing stage alone covers a rigorous 765-point inspection of everything from the HVAC system to diverter flashings on the gutters to make sure that when you come in, the weather stays out.

At William Lyon Homes, we are dedicated to maintaining high standards of quality in each home that we build. Equally important is our commitment to customer service. A representative from our Warranty Department will contact you within 3 business days from submitting your service request(s).

What's New!

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:

  • Create and submit warranty requests electronically.
  • Monitor the progress of warranty requests.
  • Electronically sign-off warranty requests.

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.

Thank you!
