I own a 1923 cedar sided center hall colonial house. It has 4 wood steps going up to the wood porch. The steps need to be replaced. I thought about building the new steps out of brick and then using sandstone for the treads. The current wood steps are built off on a concrete pad. I dug below the concrete pad on one side to see if I could find a footer. I found some red brick/red clay tile. This might indicate the house probably was originally built with brick steps. My question is, if I build new brick steps, do I build them off of the pad or do I remove the pad and the old footer and start new? I want these steps to last as long as I own the house.
I would say, depending on your area, that a frost footing would be needed. If you live where there is frozen ground in the winter, it would be necessary. However, depending on how large you will be making the steps, you might get away with just going over the old brick.
