Proudly serving Costello’s Ace Hardware in Great Neck.

I am writing to express my appreciation for the Great Neck Ace for the staff’s efforts to accommodate during Hurricane Sandy. Essential items such as flashlights and batteries were well stocked and efforts were made to replenish the stock. Lanterns and other storm items were brought in. Facility was provided to charge cell phones.

I am a very satisfied customer and wanted to let you know that your new Great Neck store is a wonderful resource. Today, Mr. Corey Petrie assisted me in the selection of a Benjamin Moore paint and primer for a bathroom. I had previously purchased paint in a home improvement store and was disappointed with the results. Mr. Petrie was extremely knowledgeable, patient and courteous. It is obvious that your employees are well trained professionals who take pride in their products and company.
