What Our Customers Are Saying

Ryan K.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.
