Really helpful friendly and knowledgeable staff. The prices are among the best in Durham for landscaping supplies. Even when they don't have the resources to fulfill your needs they will direct you in the right direction to find what you're looking for!

Ordered a delivery of 2 tons of topsoil from Kamstra. First and last time. Never again. The delivery driver was so miserable. He caused damage to my front yard. Reversed the truck on to the grass. Dumped half top soil onto my driveway. When I called to voice my concern, they asked me to email them the pictures of damage and they will pass it on to the owner. Nothing back from them. Poor customer service. Try calling them, you will be lucky if they answer after half a dozen tries.
