Incredibly helpful staff! Each time we’ve come for some amateur projects, Chris R. in the back has helped us with wood selection, cutting, and gave us some tips on how to finish our project. He was able to find a unique size of wood that we needed for a great deal!

These guys might easily end up being the best in the business. Best in New York! They have a humongous selection surpassing franchises like Home Depot. 10/10! Say hi to “Joe”!
