Repairs often mean simple replacement of worn or used components intended to be periodically renewed by a home-owner, such as burnt out light bulbs, worn out batteries, or overfilled vacuum cleaner bags. Another class of home repairs relates to restoring something to a useful condition, such as sharpening tools or utensils, replacing leaky faucet washers, cleaning out plumbing traps, rain gutters. Because of the required precision, specialized tools, or hazards, some of these are best left to experts such as a plumber. One emergency repair that may be necessary in this area is overflowing toilets. Most of them have a shut-off valve on a pipe beneath or behind them so that the water supply can be turned off while repairs are made, either by removing a clog or repairing a broken mechanism.
The term handyman increasingly describes a paid worker, but it also includes non-paid homeowners or do-it-yourselfers. Tasks range from minor to major, from unskilled to highly skilled, and include painting, drywall repair, remodeling, minor plumbing work, minor electrical work, household carpentry, sheetrock, crown moulding, and furniture assembly (see more complete list below.) The term handyman is occasionally applied as an adjective to describe politicians or business leaders who make substantial organizational changes, such as overhauling a business structure or administrative division.
