I have a building in Ballard and am in the middle of reflooring (carpet and tile) all four fabulous apartments, including my own. I have recently become acquainted with Al at American Drapery & Carpet.
With locations in Seattle, Lynwwod, Renton and Redmond (to name a few), AD&C offers terrific service, timely installation and great value. The selection I reviewed was limited (as I was looking at carpet for apartments), but I am sure they will have something you like.
Call Al (425-981-4637 and 206-769-5848). The service and attention inspires enormous confidence, even first time contracts. And there is nothing like new carpet!
