I am thinking about replacing the railing and stairs around a brick and cement landing outside a side door. I have attached a few pictures with the areas I have questions about. First, what is the best way to attach the rail to the house through vinyl siding. Second, how best to anchor the posts to the cement landing? Lastly, how best to anchor the post for the top step to the cement landing. Here are a few pictures. Please ask whatever questions you have.
