What Happens During a Chimney Safety Inspection?

A chimney inspector performs a visual inspection of the structure to look for structural damage, blockages or excessive buildup. They look at all parts of your chimney, inside and outside, to look for cracks, water damage, missing components or other issues. Cleaning isn't part of a basic chimney inspection, but you can often add cleaning services to the inspection.

The extent of the inspection depends on the level of inspection you choose, with options ranging from level one to three. Your situation and the circumstances surrounding the inspection often determine which option you need. Here's a breakdown of each option.

Level One

This is the most basic option with the least invasive protocol. You typically need this option if you haven't had any issues and you're using the system the same way you've always used it. It checks the soundness of the chimney, flue, appliance and connections.

During the inspection, the professional visually checks the readily accessible parts of the system. They look at the flue and the appliance itself.

Level Two

Level two inspections take a closer look at the internal surfaces of the chimney. This usually happens via video scanning or other tools. The inspector may also check the chimney in the attic, roof, basement or crawl space. Choosing a level two inspection is appropriate for these situations:

• Changes to the system, including installing a different appliance or changing the fuel type

• Selling a property

• Operational malfunctions

• External events, such as severe weather or seismic events

Level Three

If a level one or two inspection indicates issues or hidden damage is suspected, a level three inspection may be required. The inspector may remove part of the building or chimney structure during the process to get a better look at the suspected issue. Examples of parts that might be removed include the chimney crown and the interior chimney wall.

Why Are Fireplace Chimney Inspections Important?

Why do you need a chimney inspection? Your chimney is an essential part of your fireplace or other heating system. It allows the smoke, carbon monoxide and other byproducts to escape your home safely. Chimneys also provide ventilation to help with the combustion process. When there's an issue with the chimney, it poses a risk to your home and family. Reasons you need a chimney inspection include:

• Fire prevention. Residue called creosote forms in your chimney. Because it's highly flammable, it can cause a fire in your chimney, which can spread quickly.

• Reduce carbon monoxide. Carbon monoxide (CO) is a natural byproduct of combustion. When your chimney is in good condition, CO exits your home through the chimney. Blockages could cause the deadly gas to build up inside your home, where it can make your family extremely ill.

• Indoor air quality. Blockages also trap other particles inside your home, hurting the indoor air quality. This could cause irritation or respiratory issues.

How Often Do You Need a Chimney Inspection?

It's a good idea to have a professional chimney inspection at least once per year, regardless of how often you use it. When possible, schedule your inspection before you start using your heating source for the year — late summer or early fall ensures you can get your chimney checked and have any issues fixed. Having your chimney cleaned at least once per year also keeps the system safe.

Other events and circumstances might also warrant having an inspection. If you move into a home with a fireplace, have it inspected as soon as possible. Wait to use your appliance until you've had a professional inspection. It's also helpful to schedule an inspection if you make any changes to your fireplace or heating system. This ensures the chimney is in good working order and compatible with the upgrades you make.
