The phrase signifies informal, often substandard, workmanship or materials used in a construction or repair project, specifically when those projects are undertaken at a home improvement retail environment. It suggests the resulting work is of poor quality and lacks professional execution. For example, an improperly installed plumbing fixture bought and installed without professional assistance could be described using this term.
The term’s importance lies in its succinct communication of expected quality. It carries connotations of cost-cutting measures leading to deficient outcomes, and a lack of adherence to professional standards. Historically, the concept may stem from the contrast between professionally done construction and the increasing availability of do-it-yourself home improvement projects, often resulting in variable quality depending on the homeowner’s skill and knowledge.
