Well I am a DIY self-fixer from way back. I figure if I can work on military and commercial aircraft, I should be able to work on different things around the house. Plumbing is just not my favorite. After all is said and done, it was cheaper that calling for a plumber (sorry Mark).
I did re-grout the shower floor a few weeks back. That was a learning experience in itself, but it came out pretty good. Many years ago I enclosed the garage into a family room, with a bay window. I did the dry wall and electrical work. I sold the house back in 1985. The family room is what sold the house. 25 years later the same owners are still in the house with the enclosed garage.
B2TB – I also do not work on autos any more. It’s too confined and too computerized. The days of the backyard mechanic are just about over. I have a garage do most of my small work. I no longer change the oil. I can’t get under the car (the car is to low to the ground) and I can’t hardly see the filter let alone reach it. These are two signs of old age … too big to get under the car, and too blind to see anything. LOL!!!
I think the DIY depends on how confident you are in yourself. Anybody can do anything if they put their mind to it. Also practice make perfect. So practice before attempting any task, no matter if the job is big or small.
