I had the pleasure of working with Matt Dorminey from Carpet to Go Bellevue.
The Carpet To Go experience was very different from the other four people I'd dealt with (that big box store being the worst of the bunch, and most expensive). Matt listened to me and answered all my questions. He was extremely knowledgeable about his products. He was kind, and there wasn't any high pressure sales to buy the expensive product. I was extremely impressed with Matt.
Better yet, the price was far below what anyone else had quoted, for a better product (originally was going with Pergo, but changed to COREtec LVP). Plus there's a five year warranty on installation (no warranty with private contractors, one year with the big box store). In addition, by going through Costco, there was a Costco Shop card bonus, which is nice little incentive.
I highly recommend Carpet To Go of Bellevue for your flooring needs. Be sure to ask for Matt. You'll be happy you did.
