Yes, you should seal and cap an unused chimney to protect it from damage. Sealing the structure helps prevent moisture damage, which can lead to issues like cracks, spalling, efflorescence, and damaged mortar joints. Capping the chimney is also crucial to prevent blockages, damage from invasive critters, and downdrafts, while still allowing for proper air ventilation to manage moisture. For the best results, consult a chimney professional to select the right type of chimney or flue cap for your home. It's also wise to continue with annual chimney inspections to maintain the structure's integrity.

You should schedule a fireplace inspection at least once a year, per the National Fire Protection Association (NFPA). However, this is the minimum requirement even if you’re diligent with fireplace maintenance between uses. If you suspect your fireplace is malfunctioning, schedule one sooner to avoid fire hazards or the release of harmful emissions like carbon monoxide in your home.

It’s technically possible in some areas to install your own fire suppression system, but it’s usually not a good idea. Your system must conform to the fire code in your area and will need to pass a rigorous inspection before being activated and deemed safe. Installing a fire suppression system is a complicated job, and making mistakes as a DIYer is likely. Those mistakes can cause you to fail your inspection, which means you’ll have to spend more time fixing the issues or money to have a certified plumber do the work for you. It’s best to hire a professional.
