What to Ask During Chimney Inspection?

Types of Chimney Inspections

Before you even pick up the phone, it’s a good idea to understand the different levels of chimney inspections. The National Fire ProtectionAssociation (NFPA) defines three levels, each for a different situation. Knowing the right level for your needs will help you ask the right questions from the start.

Level 1 Inspection: This is the most basic type, and it's what you'll get during a routine annual cleaning. The inspector will check the readily accessible parts of the chimney, the flue, and the firebox. They’ll look for any obvious signs of damage, blockages, or creosote buildup. This level is for chimneys that have been used regularly and are not being changed or sold. It's a standard visual check to ensure everything is in working order.

Level 2 Inspection: This is a much more thorough inspection. It includes everything in a Level 1 inspection, plus a detailed internal examination using special video cameras. The inspector will use this camera to look for hidden cracks, damage to the flue liner, or any other issues that aren't visible from the outside. A Level 2 inspection is required when:

• You are selling or buying a home with a chimney. In places like Cambridge, Massachusetts, where many homes are historic, a Level 2 inspection is a crucial step in the real estate process.
• You are making changes to your heating system or chimney (e.g., changing from a gas insert to a wood-burning fireplace).
• There has been a serious weather event or a fire, and you need to check for hidden damage.

Level 3 Inspection: This is the most in-depth and invasive inspection. It's only needed when a Level 1 or Level 2 inspection uncovers a serious problem that can't be fully assessed without taking apart part of the chimney or home. This could involve removing portions of the interior walls, drywall, or the chimney itself to get a clear look at the structural components. A Level 3 inspection is a rare but necessary step for serious, hidden issues.

Knowing which level you need for your situation is the first step toward getting the right service.

Key Questions to Ask Your Chimney Inspector

If you're wondering What to Ask During Chimney Inspection, you're on the right track. Asking smart questions shows that you're a responsible homeowner, and it helps you find a truly professional and trustworthy inspector.

• "What is the overall condition of my chimney?" This might seem obvious, but it's important to ask for specifics. A good inspector will be able to explain the condition of the flue liner, the damper, the chimney cap, and the exterior masonry. They should use simple terms to explain what they found, not just technical jargon. You should also ask them to show you, if possible, what they are talking about.
• "Are there visible cracks, leaks, or structural issues?" Don't be afraid to be direct. Cracks in the flue can be a major fire hazard, while a leaky chimney can lead to costly water damage inside your home. Cracks in the flue can be a major fire hazard, while a leaky chimney can shorten the system’s lifespan (learn more in How many years does a chimney last). A professional inspector should be able to spot these issues immediately and explain what caused them.
• "Is the chimney sweep properly trained and regulated?" This is a question about qualifications. Look for inspectors who hold certifications from recognized organizations like the Chimney Safety Institute of America (CSIA) or the National Fireplace Institute (NFI). These certifications mean they have met a high standard of professional knowledge and ethics.
• "Is the chimney sweep insured?" This is a question you should never skip. A professional company should have proper insurance to cover any accidental damage to your home or injuries to their workers. It’s a protection for both you and them. If they can’t show you proof of insurance, it’s a major red flag.
• "Will the chimney sweep take appropriate steps to ensure my property is clean and safe while they work?" This is a very practical question that addresses a common worry for homeowners. A professional inspector will use drop cloths, tarps, and powerful vacuums to contain soot and debris. They should be able to explain their process for keeping your home clean before they start any work.
• "Does the chimney sweep conduct a safety inspection?" A safety inspection is different from just sweeping for soot. A safety check ensures that the entire system is working properly and is free of fire hazards. It checks for proper airflow, blockages, and the overall structural integrity of the chimney. This is a vital part of the service, and a good company will always include it.
• "Does the chimney sweep guarantee the work?" Ask about warranties or guarantees on their work. While you can't guarantee a chimney won't get dirty again, a professional company will stand by their service and address any issues that arise shortly after the cleaning.
