Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

The NFPA model codes and International Residential Code (IRC) mandate that all new one- and two-family homes have fire sprinkler systems. However, all municipalities are different. The best way to determine if your municipality requires fire sprinklers is to contact your state fire marshal’s office. One reason to install a fire sprinkler system is that it’s the first line of defense in putting out a fire and alerting your family of emergencies.

Home insurance prices depend on where you live and the individual insurance company's policies. Some insurers charge a flat fee for fireplaces or wood-burning stoves, which is often a few hundred dollars per year. Other insurers base this fee on a percentage of your annual premium. You may want to check your current or prospective policy before beginning this project.

Smoke detectors come in two different options: hardwired or battery-operated. While hardwired units are attached directly to the home’s electrical system, a battery-operated smoke detector only needs a simple battery for operation and can be placed virtually anywhere in your home. Some homeowners may mistakenly think their battery-operated units are hardwired in because all their units are interconnected, but many battery-operated units can operate within a smoke alarm network in your home.
