Understanding Mounting Types and Different Style Options for Wall mounted Fences and Railings- Wall mounted fences and railings can offer some questions and challenges when it comes to rigidity. A good connection to solid structural masonry units is ideal. Here are a few common installation scenarios we have encountered, and some solutions for a successful end product. Block Walls- Cinder block walls are the most commonly encountered masonry fences and curbs in residential construction. Fences can usually be surface mounted or fascia mounted to a solid block wall. If the wall is hollow; the cells which support the fence post should be grouted solid. If the wall is capped like the one in our feature photo; the anchoring should penetrate past the wall caps into the solid wall. Threaded rods that are epoxied into the wall will function well. In addition, a variety of masonry anchors are suitable for mounting railing posts on to masonry walls. Keystone Blocks– Keystone blocks are very appealing to DIYers because of affordability and their easily stackable design. The blocks come in a variety of sizes and stack on top of each other. Keystone blocks are held in place by a lip on each block and the backfill pressure against the blocks. Keystone blocks are not typically a good choice for top mounted fence and railing posts because the top block can move. Fences and railings should be cast into concrete footings utilizing the compacted fill behind keystone walls for best results. Footing depth can vary for these types of installs.

They are typically wood framed and veneered in drywall (inside) or stucco, stone, tile (outside). Knee walls can be a great mounting frame for fence and railing posts. The most important considerations are the framing thickness and waterproofing. Pony wall top plates should have a 3″ net thickness in order to offer a good lag bolt connection. If a fascia mount is desired; wood blocks should be installed at the post locations.  Wooden framing members should be properly wrapped (waterproofed) in order to prevent water intrusion. Sealant should be used on all bolt threading and around the plates when installing the fence posts. Wall mounted fences and railings can be a beautiful improvement to interior and exterior spaces.
