I don't know how people do this full time.
It's HARD work (hard on knees and back and shoulders, etc.). We worked 12 hours on Sunday to get it finished.
In the past 5 or so years, we've also done 5 tile projects in our house.
Every year as we get older, it takes a bigger toll on our bodies.
I'm impressed and proud we can do this, but wish we had the strength and youth to do it professionally. There are always people wanting us to do their home and we even thought about flipping, but our bodies will fall apart.
We have a couple of guest rooms we thought about hardwood installs for, but we might just replace the carpet.
