DIY
Home maintenance involves the diagnosis and resolution of problems in a home, and is related to home maintenance to avoid such problems. Many types of maintenance are "Do it yourself" (DIY) projects. Maintenance is not necessarily the same as home improvement, although many improvements can result from repairs or maintenance. Often the costs of larger repairs will justify the alternative of investment in full-scale improvements. It may make just as much sense to upgrade a home system (with an improved one) as to repair it or incur ever-more-frequent and expensive maintenance for an inefficient, obsolete or dying system. For a DIY project, also useful is the established limits on time and money investments before a repair (or list of repairs) become overwhelming and discouraging, and less likely to ever be completed.
