Provo’s Joaquin, Franklin, and Maeser neighborhoods hold some of the city’s oldest housing — plaster and lath walls, additions built onto foundations that predate them, crawl spaces that were never sealed the way a modern build would be. Moisture gets into those gaps and stays, sometimes for years, before it surfaces as a smell or a stain.
We treat what’s actually there rather than assuming a one-size answer. An addition with a mismatched foundation gets checked differently than an original crawl space, because the moisture is usually coming from a different place in each.
