That’s really thoughtful of you, actually. An old porch, especially if it’s your parents’ house, can even be dangerous to use, so it really is better to fix everything up before anything bad happens and someone gets hurt. For porch repairs or pretty much any kind of work, I really recommend these guys https://oakshs.ca/front-steps-entryway/. I don’t have a ton of experience with contractors like this, but I went to this company on a recommendation and I’m super happy with how the front of the house looks now, especially the porch.
