I always enjoy looking at photos of their own work that Wallies post on The Wall at HeatingHelp.com. It’s not easy to do because The Wall is home to some of the sharpest contractors in the business and they can be pretty blunt while still being helpful when it comes to answering the question, “Here’s a job I just finished. What do you think?”
The contractors who post their photos usually think their work is good enough to show off, but the others (most of them being contractors themselves) will point out ways in which the work is great, almost perfect, and then they will pick nits to make it better. And that is how we all learn. We learn by asking and then by sharing.
