Home improvement is a popular pastime for many Americans, with the popularity of shows like “Fixer Upper” and “This Old House.” While it’s fun to watch your favorite TV star swing that hammer, jumping into a home renovation project without a plan can lead to disaster. To help you avoid getting in over your head, here are some tips and tricks to make your next project a success.

The most common reasons for home improvements include improving living comfort, adding functionality and increasing resale value. But it’s important to remember that not every renovation adds value, and some may even decrease resale value. For example, an in-house theater room may be the perfect addition for any movie buff, but it could deter potential buyers who would prefer a more functional space with the ability to adapt to future technology.

Many home improvement projects are labor intensive, time consuming and costly, but the benefits can be great. For example, a new kitchen can increase your return on investment by up to 50 percent. A bathroom remodel is another high-return project that can significantly improve your home’s livability and value.

It’s also worth noting that some repairs are simply necessary. Electrical problems and roof leaks, for example, are often safety concerns that can’t be ignored. Likewise, lead paint removal should be done by a professional to protect your family from exposure. In all cases, be sure to talk with your home insurance agent before starting any work to see if your policy needs to be updated.
