I have a country style front porch that has non structural wooden columns that are anchored to the overhang and hang to the floor, a concrete pad. To stop the columns from moving around the builders wedged a shaved 2x4 between the column and the concrete. A railing is strung on the columns. Depending on the temperature decides how sturdy the columns are held in place and if anyone puts any weight on the railing a column will swing around. How can I fix this?
