If your in the market to buy fence materials. John and his guys are the way to go. Very kind, professional, and efficient in their work. They’ve given me quotes for a few jobs and bought fence from them. They have the best prices in the mountain west and high quality materials.

I purchased a special order metal reinforced vinyl gate for our community association. WOW. The quality is well beyond any DIY store. Plus Jon was friendly to work with and gave me great videos for a smooth installation. In Florida, we deal with hurricanes. I will never by a fence from anyone else again. Thanks WVF

Have an overall good experience with Chris (salesman), very informative and knowledgeable about his project…. Helped with some cost of delivery, to help bring in delivery date… Haven’t installed the fence yet, but will post pic of final install once I have..

We did a great deal of research before coming across wholesale vinyl. During the first call to wholesale vinyl, the sales team was incredibly helpful in answering all of our questions and making appropriate recommendations for the needs pertinent to the area in which we live. Fencing products at a great price much better quality than we would have paid at national hardware chain stores. We are absolutely thrilled with the experience and will buy again
