What Our Customers Are Saying

Ryan W.Mar 26, 2022

Since moving to deer park this is the store I goto for all my basic home maintenance needs. Bruce I’ve had the pleasure of speaking to and he has been super helpful each time! True professional! Met Liz today she made some stellar recommendations for a painting project I’m tackling. Very satisfied with their service and I feel fortunate to have them in the neighborhood.

Amazing customer service, the employees there always know how to help and where everything is

Best local hardware store. Reminds me of the closed and now gone Commack Hardware of my childhood. People know what they are talking about, they are very helpful. They now do curbside and free delivery! Only go to Home Depot for specialty items or if I know the price will be significantly less, otherwise they get all my business, and everyone else’s, always doing well. They have a massive location on Grand, and one in South Farmingdale, but this place is great as is.
