They get a 10 rating from me. Old fashioned way of doing business... Putting customers first. They don't need to brag about customer service because everyone that's been in the store more than once knows they are going to get it.


Ace really is the place. If you are looking for a special nut, bolt or any kind of oddball fastener, odds are that Ace has it. Unbelievable stock always. Customer service is always great at the Hamburg store.


I'm a regular customer here and the lumber and trim are of better quality and cheaper than the big box stores. The service is amazing. If you want to go somewhere where they call you by name, this is the place to become a frequent visitor. The hardware store itself has everything you could think of and a lot you wouldn't.


The amount of inventory in the place is crazy. Always have everything I need and 9 times out of 10 they are cheaper than the Depot or Lowe's. The staff is so helpful. I challenge anyone to find someone in the industry more knowledgeable in hardware and solving my problems than the manager of this store. Always look forward to going here.
