What Our Customers Are Saying

All home improvement projects and everyday home accessory needs should start at Ace. Not only are their prices fair but the local knowledge cannot be found at a big box store. Ace is my first stop and in most cases also my last stop. Thanks for being in the neighborhood!

The staff are always friendly and helpful, the location is super convenient near other shopping stops, and the store is always clean and well lit. YES, the prices are about 20-25% higher than Home Depot or Lowes, but this is so much easier than farther away to the bigger box stores and fighting the larger crowds and parking lots. You should check their inventory online because they do have smaller selection being a small store. Sign up for the rewards program to get the regular % off and $ off coupons, which makes the prices much more comparable....also they do discounted specials on their own gift cards around Black Friday and Christmas. Strangely, the Ace store in Severna Park is owned by a different family so the computers don't cleanly accept each other's coupons but they always are willing to match and do an override. We bought our gas fireplace here as well and overall had a nice experience with them overall, we like supporting this little local store.

Contacted Costello's Ace about installing a pellet stove insert at my house. During the discussion, I expressed concerns about the existing fireplace setup and provided photos/measurements to the sales person. He spoke with someone and they said it was not going to be an issue. Fast forward to the pre-installation. The person measured and we realized it would not work (the surround would not fit). The pictures provided definitely show that it would have been an issue before the pre-installation visit. In the end, I was refunded the deposit, except they charged a $100 pre-installation visit fee. Rather ridiculous as they should have not even gotten that far along in the process. In the end, don't buy a stove insert from Costello's. The sales person will tell you what you want to hear. Update: Their sales manager reached out and profusely apologized for the issues I encountered. They refunded the cost of the pre-inspection and offered to look into alternatives for getting a pellet insert.
