Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.

Wiring a light switch wrong can cause a fire if the incorrect wiring causes arcing, meaning the current jumps uncontrolled from one conductor to another. Loose wires or worn wires that are not repaired or replaced can cause arcing. If you’re not 100% sure you can do the job safely, don’t attempt to wire a light switch on your own.

Although you can put a smoke detector on a shelf, the NFPA recommends mounting one on the ceiling or a wall (within 12 inches of the ceiling). If you place your smoke alarm on a shelf, ensure it’s away from drafty, damp, or dusty areas and not near cooking appliances, heat sources, or fluorescent lights.

You can install your own fire door, but since it’s a safety measure in your home (and often the only way to passively slow down a fire), you should rely on professional door installers. These contractors know exactly what to do and how to do it, and in our opinion, their costs are worth every penny.
