Spokane has some of the wildest old house problems I've ever seen, my buddy lives out there. That whole thing with the scribing reminded me of how nothing in old houses is square or level, same with old furniture. I've got a 1920s dresser that rocks on three legs unless I put a folded coaster under one corner. It's like every old thing has a built-in wobble that you just have to accept or fight forever.

Did you already have a fresno or a bull float before you bought the power trowel, or did you just jump straight into the deep end with a machine? I'm curious because those garage slabs can be a real pain to finish by hand, and it sounds like you made the right call. Was there one particular job where you thought "man, I need this thing" or did you just gamble on it paying off?

Yeah but heres the thing nobody talks about. Power trowels are great if you have a perfect subgrade and your mix is exactly right. But if you have any soft spots or a little too much water in the concrete, that machine will just smear it around and hide the problems. Hand troweling forces you to actually fix the low spots as you find them. Ive seen power jobs that looked flat until you lay a 10 foot straightedge on them and find a quarter inch dip right where the trowel skipped. The owner probably wouldnt have even noticed until he went to put in his workbench and it rocked. So yeah your back took a beating but you saved him from that headache. Plus theres something about the feel of the concrete changing as it sets. You cant get that from a machine.

Mike's 20 years in Cleveland taught him that reliability beats convenience every time, same as my uncle who still uses a landline.

Second that completely, @sage_lewis10. Turning a mistake into a free fix shows you care more about the person than the profit, and people remember that way longer than a perfect job.
