Home improvement is the renovation, alteration, repair, restoration, decoration or modernization of a residential or noncommercial property. It also includes the construction of additions to a home or the creation of an outdoor structure like a deck, patio, garden shed or fence. Home improvements can be categorized as minor or major in scope, but all should increase the value of a home, reduce maintenance costs and enhance livability.

Home improvements that make the most sense in the current market include installing energy-efficient appliances and putting in new doors and windows, which can save on utility bills and increase security. Also, a fresh coat of paint can transform dated interiors and exteriors. But be sure to gauge your interest level before tackling a project, especially if you’re an amateur handyman.

If you’re renovating with a view to sell, talk to real estate agents in your area about which projects are likely to boost your home’s value and which may detract from it. Some gimmicky additions, like top-of-the-line appliances and imported marble countertops, may turn buyers off.

Before starting any home renovations, it’s important to research local contractors and get estimates for the work you need done. Make sure the contractor is licensed in your area, and ask for references and proof of insurance. Using an unlicensed contractor puts you at risk for shoddy work, injuries to workers and damage to your property. Also, if the worker is not insured, you could be held liable if something goes wrong.
