Masonry repointing: when should you choose lime vs cement in century homes, and what are the moisture implications?
Lime mortar is usually better for old homes than cement. It’s softer, so the house can shift a bit without cracks. Plus, it lets moisture out, which keeps water from wrecking the bricks. Cement is harder and doesn’t breathe as well, which can make old bricks crack. What you pick really matters for how your walls handle water and how long they last!
