Such a pleasure to go there. As soon I walked in the service was amazing, polite and professional. I was even offered a cup of coffee while my paint was being mixed.

Can not express enough how I love this local, helpful, friendly hardware store. I’ve been a customer since Costello took it over n I don’t know what I would do without the wonderful staff. Infact I feel like everyone is like family I go so open. They have a staff of young, knowledgeable, polite n know how to answer n help with any issue u may have. My go to this store n leave with a smile from talking to the employees. Thankyou Mr Costello for bringing this store to my home town.

I was there to get a new battery and key for my car. They couldn't get to the battery bc screws were too rusty. So I told them not to worry and just make a new key. As it happens, they didn't have that in stock and would require to order one which would change my traveling plans. The manager and his staff were so friendly and helpful I was so gladly surprised to see how they were to willing to help me even if they couldn't. As opposed to other places where they say we don't have it or we can't and that is the end of the story. It really was a pleasure to walk into this ACE store in East Islip NY.

Ive never had a bad experience at this store. Everyone is always so helpful, but one worker stands out. Joan is the kindest, most helpful, and most personable employee at this store. She always knows the answers to all of my questions and makes my experience quick, easy, and enjoyable. I highly recommend talking to Joan next time you’re here, she deserves a huge raise! In fact, make her the CEO of the company!

Definitely "the home of the helpful hardware folks". On more than one occasion I was about to leave empty handed but before I could walk out one of the crew will ask "did you not find what you were looking for" and after I tell them what I was looking for we go back and they find it. I think each time I left with a smile on my face.
