There aren’t many problems with fire doors except that they slow down or cut off ventilation at the higher rating levels. For this reason, work with a professional to ensure you have adequate ventilation throughout your house or workspace. The sealing around a fire door is meant to allow for a specific amount of ventilation and will need regular inspections to ensure adequate airflow.

Wood-burning fireplaces typically make homeowners insurance more expensive, simply because they increase the risk for a fire in your home. Gas and electric inserts are less likely to bring up your insurance rates, but you should always speak with your agent to understand how installing any type of fireplace will affect your premiums.

Shiplap can be safe for a gas fireplace, but you should consult with a fireplace installation pro before proceeding. You need to make sure your project meets building and safety codes since shiplap is made from flammable wood. You may need to install another non-combustible material, like stone or brick, around the fireplace for a certain amount of space before you can add shiplap.

Certified fire door inspectors should inspect fire doors. These professionals receive training to specifically assess the condition, functionality, and compliance of fire doors. They often hold credentials from groups like the Door and Hardware Institute (DHI) or the International Fire Door Inspector Association (IFDIA). While fire marshals won’t usually do hands-on inspections, they’ll check that doors are being maintained properly during routine safety audits. If a building relies on fire doors for code compliance, it needs someone who understands the details—the difference between a cosmetic issue and a safety failure—and standards to sign off with confidence.
