Thirty years ago not many people would have dreamed of doing the repairs and decorations in their own homes. In those days labor was fairly cheap and most people would have thought it worthwhile to employ a professional painter and decorator, unless of course they were either very hand up or were in the trade themselves.
Today, however, it is quite a different story. Men and women in all walks of life turn their hands to all sorts of jobs round the house including painting, papering, putting up shelves and wall units, and tiling walls and floors. Some people with no professional training of any kind have even successfully built their own houses. These jobs have been made easier today by the introduction of prepared materials, which require the minimum amount of skill to use. In every high street throughout Britain nowadays there is at least one “Do-It-Yourself” shop containing a vast range of timber, tiles, paints, wallpapers and floor coverings besides tools of every description including power drills and many accessories. “Do-It-Yourself” is a booming business; all these shops do a roaring trade and look like continuing to do so. Probably the main reason for the craze is the high cost of present-day labor and the shortage of building firms willing to do small jobs.
