What Our Customers Are Saying

Hannah B.May 30, 2023

I always choose this location for key-making needs for my job. I find that the staff is knowledgeable, attentive, and helpful. I wish I took down the names of all the guys who helped make keys. Thank you!

This is not just an ordinary Ace Hardware store. It has just about everything. I needed 4" vinyl duct for a bathroom ceiling fan - no problem! A 700 lumen A15 clear light bulb. No problem. And if they don't have it they will check all the other Costello stores for you or order it.
