What company does Costco use for garage doors?

Costco uses Amarr Garage Doors as its exclusive residential garage door supplier through the Costco Garage Door Installation Program, paired with LiftMaster openers. The program is delivered by a network of Amarr-authorized dealers in each market, who handle the in-home estimate, removal of the old door, installation, and warranty service. Available models include the Lincoln, Stratford, Hillcrest, Heritage, and Classica collections, along with insulated and non-insulated options. Costco members typically save 5 to 15 percent versus retail and earn 2 percent cash back through the Executive membership. Pricing for a complete double-car door, opener, and installation usually lands between 2,500 and 5,000 dollars depending on the line and any insulation, window, or hardware upgrades.
