DBC has supplied nearly all our landscape project needs, and their products are always top quality! Their Longmont team is friendly, knowledgeable, and always ready to help when questions arise. Their reliability and excellent service have made a huge difference for our small business- Acosta Landscapes—helping us deliver great results and keep our customers happy. We highly recommend DBC for all landscaping supplies!
From the outside you might think that they only supply large landscaping companies but they do sell retail to do-it-yourselfers. I have even gone in and gotten one $2 part and they treated me the same as guys getting thousand dollar orders. Additionally, they are extremely helpful and courteous. Two qualities not found in big box stores.
If you need sprinkler/irrigation supplies, this is the end-all shop for what you need. Definitely slightly higher prices than the big box stores, but unlike the big box stores, they always have what you need. And they know what they're talking about.
Great store the the Landscape nerd. Came in looking for some nozzles for my sprinklers. Asked for 40 and the lady diligently directed me to them and helped count them out for me. Gave them to me for no charge. Definitely will be back soon!
Knew exactly what I was looking for and where to find it in the store. Considering it was the fifth place we had looked, I wish we had gone here first! Great team - helpful, patient and knowledgeable.
