Ever try to run wire in a house with no crawl space? My friend got hired to put a hardwired system in this ancient bungalow. He had to cut tiny holes in the closets to snake cables between floors, and he used a coat hanger to fish them through the walls. It took him three days just to get all the sensors linked up, and he was covered in dust and insulation. But he swore the solid click of each connection felt more sure than any wireless signal. That kind of work really was its own art form.

My bathroom faucet swap turned into a three-day flood, so I finally get what thomas_dixon53 meant about surprises being a hard lesson.

Lol, but is it actually a big deal? Weekend work happens sometimes.

Torque wrenches are a safe move, but over-tightening gets too much blame. I've seen way more bars messed up from cross-threading during installation lol.
