Was this store once called Concord Hardware?

There one was a Concord Avenue hardware. Owned by Boots Rose. To my knowledge there never have been Concord hardware. Bill' Ace was formerly just Ace Hardware on Treat Blvd

Echo what Martin has stated... always have been Bill's Ace.

No but it's the same owner as all the ace hardware's I've ever known to be in Concord. Their really helpful, knowlegabe, and easy to find staff combined with hard to find hardware solutions they are a good choice.

Not that I recall.
