Showerthought: People who scoff at carpet install have never stretched a seam in their life.
I was at a family thing a while back and this cousin of mine said it's just glue and cut, no big deal. Let me tell you, try getting a perfect fit on a winding stair with no gaps. On a recent job, the subfloor was so uneven I spent hours with leveling compound before I could even think about the carpet. Customers watch you like a hawk, expecting magic, but have no clue about the prep work. And when you're on your knees all day, your back screams by noon. It's not just laying down fabric, it's geometry, physics, and pure elbow grease. Show some respect or try it yourself.
