Is there a bracket or product that I can use to mount fence panels to a house or column or building?

Yes. See Fence Accessories.
We carry straight mounts / brackets that will allow you to attach one or both ends of a fence panel to an existing structure (house, building, wall, column). You will need to purchase anchor screws (stainless steel) locally whenever you are making a connection between our products and your existing structure (house, building, wall or column).
