Slab foundation built in 2002.No clue about post tension or pier and beam.Noticed some cracks on exterior,door sticking,interior cracks above doors,and gaping around the 1 piece shower insert in the guest bathroom and the sheetrock.I don't have any experience using any. I'll ask around this week and see if anyone I know have one to recommend.
What's going on? Crawl space or slab floor? Post tension or pier and beam foundation?
