Hello. This is my first post here, resorting to asking for advice on how to approach crumbling concrete steps to the porch of my house. I"m attaching some photos that hopefully will explain what's going on. The steps appear to have been patched before, but poorly. I can access the back of the steps under the porch from the basement in order to frame up and pour to fill, but will this work? Each step appears to be ready to fall apart. My thought was to clean out everything that is broken, completely fill all the gaps after framing, possibly with angle irons in the back or something of that nature, and then cover the steps with some kind of sealer or topcoat. The complicated part is that the steps tie into the brick on either side, as well as the handrail. I'd really like to not have to smash it all out and start over, although I'm sure that would be the best method. I'm looking for the simplest fix that will get me a few more years before I'm ready to try and sell the place (plenty other fixes required in the meanwhile). Any thoughts or suggestions would be much appreciated! Thanks.
