We live in Bay Area with hot weather. When doing remodeling we decided to replace all windows and garden doors with Milgard products. We love the comfort and our utility bills we got after that. We love everything about Milgard products: design, insulation, sound proof and outstanding service. With any problem we had they fixed it with one short call. They replaced door rails and wheels (after 12 years of use) with new technology at no charge and it works perfectly. We'll definitely use Milgard for any new need. We recommended it to many of our friends and family and all are very pleased.
