Riverhead Building Supply 333 Hallock Avenue, Port Jefferson Station, NY 11776

"Drywall was 25% more expensive then the local big box store, but the customer service was great, they were easy to deal with, delivery was fast and the driver was very helpful. I would definitely recommend them."

"Extremely helpful and friendly staff. Gavin and Danny in the back of house were extremely helpful and knowledgeable. Very professional operation."

"Large order of decking material was delivered a few days ago and half of the material was missing. I wake up this morning to see the rest of the order laying on my lawn. The driver could have easily rang my doorbell and I would have moved my car out of the way. That is just lazy and rude!!!!!!!"

"I went to Riverhead Building Supply, looking for lumber and for the lumber to be cut for a small project (garden beds)-- something that most people would easily do on their own. The staff, especially Kevin, who helped me with my request, were just as welcoming, knowledgeable, and efficient with my request as they were with the umpteen more complicated projects that other customers had. They were very helpful and respectful in making sure I got everything I needed without an ounce of condescension. I really appreciated the level of expertise and customer service here."

"The lumber seems to be, generally speaking, better quality than what is available at the big box stores. A major plus with their customer service is that you don't have to sift through to find a good straight pieces of wood. The service was fast and the guys even assisted with loading up the materials. Because of the service experience I did not mind spending a few more dollars. When possible I recommend visiting these guys as opposed to the big box retailers."
