As a real estate agent, you’ve seen firsthand how home inspections can make or break a sale. One of the parts of the home that is sometimes forgotten about when prepping a home for the market is the chimney. Problems with the chimney or fireplace are surprisingly commonplace and can be expensive to repair, especially if they’re discovered late in the process. What are some of the most common chimney problems found during real estate transactions, and how can Clean Sweep help you and your clients?

Cracked or Damaged Flue Liners

One of the most common issues we find during pre-sale chimney inspections is a damaged or cracked flue liner. The flue liner is critical for safely venting smoke and gases out of a house. Cracks, gaps, or corrosion can create fire hazards or allow carbon monoxide to leak into the living space. These problems are often invisible without a detailed camera inspection, so a basic home inspection may not catch them. Flue liner repair or replacement can be costly, but it is necessary for safety and code compliance.

Damage to the Chimney Crown

The chimney crown, which is the concrete or mortar slab that tops the chimney, serves as the first line of defense against water intrusion. Unfortunately, crowns are prone to cracking due to weather exposure and age. Once cracked, water can seep into the masonry and cause internal damage that isn’t always visible at a glance. Crown repairs are essential to extend the life of the chimney and prevent structural issues.

Brick Spalling and Mortar Deterioration

Moisture is a chimney’s worst enemy. In places like Maryland where the winters are cold, water that gets into the masonry can freeze and expand, causing bricks to flake, pop, or break apart. Missing or crumbling mortar joints also weaken the structure. This type of deterioration can be a red flag for buyers, especially if it suggests deeper water damage. Tuckpointing and waterproofing can often solve the issue if it is caught early.

Creosote Accumulation

In wood-burning fireplaces, creosote, a highly flammable residue, builds up in the flue over time. Excessive creosote poses a serious fire risk. Most home inspectors won’t assess creosote levels, but a certified chimney sweep can. If a chimney hasn’t been cleaned regularly, it can cause buyer concerns or even lead to an insurance issue. A simple chimney sweep and inspection can eliminate this problem.

Missing or Damaged Chimney Caps

Chimney caps keep rain, debris, and animals out of chimneys. They also prevent downdrafts that can blow smoke back into the home. However, many chimney inspections uncover chimney caps that are rusted, loose, or entirely missing. A damaged or missing cap can lead to water intrusion, pest infestations, and even interior fireplace damage. Thankfully, chimney caps are relatively affordable to replace, making this a good “quick fix” before listing a home.
