Chimney Safety

As the temperature drops and you prepare to light that first cozy fire of the season, it’s important to make sure your chimney is ready to handle the heat—safely. Your chimney is more than just a passage for smoke; it’s a key part of your home’s ventilation system and overall safety. Unfortunately, it’s also one of the most overlooked components until problems appear.

At Inspected Moore, we know that Michigan winters can be harsh, and that a neglected chimney can quickly become a costly or dangerous issue. Here are some essential chimney safety, cleaning, and repair tips—especially focused on one of the most critical yet often ignored parts: the chimney crown.

Before the first fire of the season, have your chimney professionally inspected. A certified home inspector can identify cracks, blockages, or signs of water damage that may not be visible from the ground. Annual inspections help prevent hazards like chimney fires, carbon monoxide leaks, and structural deterioration.

At Inspected Moore, we recommend having your chimney inspected every fall as part of your seasonal home maintenance routine.

Creosote buildup inside the flue is one of the leading causes of chimney fires. Even a thin layer can ignite under high heat. Have your chimney cleaned by a professional sweep at least once a year—or more often if you use your fireplace frequently. Regular cleaning also removes leaves, bird nests, and other debris that can restrict airflow and trap harmful gases.

The chimney crown—the concrete or mortar cap at the very top of your chimney—is your first line of defense against water intrusion. Over time, exposure to freezing and thawing cycles can cause it to crack or deteriorate, allowing water to seep in and damage the masonry below.

Signs your chimney crown needs attention include:

If you notice these signs, it’s crucial to repair or seal the crown before winter sets in. Delaying repairs can lead to extensive water damage and costly rebuilds later.

Once the crown and masonry are in good shape, consider applying a breathable waterproof sealant. This prevents moisture from penetrating the bricks while still allowing trapped vapors to escape. Waterproofing your chimney helps it withstand Michigan’s freeze-thaw cycles and extends its lifespan.

The flashing (metal seal around the base of the chimney where it meets the roof) and the chimney cap also play critical roles in keeping water out. Damaged or missing flashing can lead to roof leaks and interior damage. A properly fitted chimney cap prevents rain, snow, and debris from entering the flue—while keeping animals from nesting inside.

If you see rust, gaps, or loose sections, schedule a repair before winter storms hit.

The type of wood you burn matters. Seasoned hardwoods like oak, maple, or birch produce less creosote than softwoods or green (unseasoned) wood. Store your firewood off the ground, away from the home to deter pests and rodents from moving in and covered to keep it dry and ready for use all winter long.

A chimney inspection is a perfect complement to your annual home inspection. It ensures your fireplace and heating systems are operating safely and efficiently.
