A general contractor oversees 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. Another strategy is to “do it yourself” (DIY). 67% of homeowners report they will do some work themselves when they remodel according to the Remodeling Sentiment Report. Several major American retailers, such as Home Depot and Lowes, specialize in selling materials and tools for DIY home improvement. These stores host classes and carry numerous books to teach customers how to do the work themselves. DIY websites also provide information, in the form of how-to videos, articles and step-by-step instructions.
