What Our Customers Are Saying

Bryan G.Feb 15, 2026

Since each ACE Hardware store is owned by their different people, they don't all do the same thing's. But the ACE at East Park Shopping Center has been there as long as Giant. I have always gone there for personal reasons, I only found out about the different owned places a decade ago. Truth be told this might be a mistake in the possibility of a customer who is in need of an item, but if one place is out now, then they could get the same thing from a connected place. When Hechingers became Lowe's, and Home Depot arrived there was no way in my mind that ACE would stay in business. But they have and perhaps it's due to them being independent stores. I just hope they last forever...

This is the only place we were able to get wood pellets during this storm and even though the place was crowded and everyone was trying to get the same thing, the employees were nice, friendly and helpful! I've been to this store for other things and never had anything but a great experience.

ABOVE AND BEYOND! I will go out of my way to use this store. You will not find that level of customer service anywhere. Unmatched. Well done Ace Glen Burnie!

This is Marcy M. Taylor was absolutely Amaziing. She helped me select and replace remote batteries for my car and garage door opener, as well as Icemelt which saved me a lot of time and money. I was very grateful for her help! She's a young and helpful smartie who is indeed an asset to your organization. Keep shining Taylor, your future is bright !

My husband and I were looking for some turkey brine. We came across Costello’s Ace Hardware store. From walking up to the door to walking out once we were finished, the service was IMPECCABLE! Mr. Dave greeted us as the door, opened the door and asked immediately what we were looking for. I told him and he went straight to where it was. On the way in the door as well, Ms. Celea at the front also asked what we were looking for. The only reason we were in so long was because I was just wandering around looking. This place just has so much that you could get all at once. To include a hot tub….. just sayin…. Sorry! Off track! Ms. Celea was very pleasant and patient. On our way out, Mr. Dave also held the door. Top notch service, even in the cold. We had never been there before but will for sure be going back for any of our hardware needs….. or that hot tub . Thank Ya’ll!!!!
