This happened to me a while back but I thought it would be good to share to possibly save someone 10s of thousands of dollars.
I had some foundation cracks and a few small cracks in the drywall of my house. I got worried and called out a foundation company that offered a "free" inspection. The inspector proceeded to tell me that my house was "sinking and breaking in half like the titanic" and I needed $25k in repairs. I became very stressed. With a repair that large, I wanted a second opinion.
I hired a proper structural engineer. It wasn't cheap, he charged me $450 to look around for about 15 minutes. I had told him what the foundation company had told me and he laughed. I ended up needing no repairs besides a point and retuck. The cracks in the brick? He said those were cracks from thermal expansion. He saved me about $24.5k.
I later read that a lot of the "free" foundation inspectors operate on a commission basis. They will always tell you that you will need foundation work, otherwise they would be going out of business. Beware of free inspections.
Renting is shit, but one of the best points not owning a home is that contracters are almost universally untrustworthy con artists.
the house im renting had been losing mortar in the chimney. im not a brick layer or anything but even i know once you lose so much its only a matter of time before one or more bricks succumbs to gravity. im not sure what they had to do but its been a lot better since they took care of it.
