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.
