You can’t gauge the lifetime of a fire door like you could, say, an engine. Fire doors should be checked at least once every six months to ensure there are no signs of degradation like leaks, holes, water damage, termite damage, or anything else that might compromise the functionality of the door’s fire resistance. Check your smoke detectors while you’re at it.

There are several maintenance tips you should take to ensure your pellet stove's safety and proper maintenance. You should vacuum the ash pan every week to prevent overflowing and clean the stove and surrounding vents every three to four months. It’s also important to get a professional inspection every year and install a carbon monoxide detector close to your stove. Be sure to dispose of hot ashes in a closed metal container; store it outside, away from the house. Only use the pellets recommended by your stove's manufacturer, and follow any cleaning and maintenance instructions.

A fireplace hearth is necessary in most areas per building codes, especially for gas and wood-burning fireplaces. Electric fireplaces may not require a hearth, so check local building codes or ask a pro for guidance if you’re leaning toward electric.

Malfunctioning switches often result from loose wiring, exposed connections, or other electrical problems that can cause overheating or sparking.

If you suspect your light switch is faulty, immediately turn off the power at the circuit breaker and contact a qualified electrician to remedy the issue.
