Home improvement is the process of renovating or making additions to one's home. Often, a professional handyman is hired to perform the improvements but, typically, most improvements are done on an amateur DIY basis by the homeowner.
A homeowner can hire a general contractor to oversee a home improvement project that involves multiple trades. A general contractor acts as project manager, providing access to the site, removing debris, coordinating work schedules, and performing some aspects of the work. Sometimes homeowners bypass the general contractor, and hire tradesmen themselves, including plumbers, electricians and roofers. Another strategy is to "do it yourself" (DIY). Several major retailers, such as Home Depot and Lowes, specialize in selling materials and tools for DIY home improvement. These stores even host classes to educate customers how to do the work themselves.
Do It Yourself (DIY) refers to the practice of fabricating or repairing things, most commonly for home needs, on one's own rather than purchasing them or paying for professional repair, usually home improvement done by the householder without the aid of paid professionals. The phrase Do It Yourself along with it's acronym is also commonly used where a layman endeavors to complete a project without the physical aid of a paid professional.
