A chimney leak is one of the most dreadful situations for a homeowner. It is not only damaging to the chimney but can also damage the integrity of your home, causing costly repairs. Most of the conditions in which chimneys are found over time are harsh weather conditions like wind, rain, snow, and UV rays, so with time, they can prove highly vulnerable to leaks. A thorough understanding of the causes of chimney leaks is one of the good beginning steps for keeping a chimney healthy and functional. Whether it’s moisture seen in the fireplace, water stains, or cracking mortar, you don’t want to waste time taking action on this.
At A Step in Time Chimney Sweeps, we pride ourselves on being best in class at diagnosing and repairing chimney leaks through extremely effective solutions that stay focused on ensuring your chimney remains water-tight and, thus, your home safe from risk. This blog will discuss some of the essential areas of chimney leak issues, the reasons why they occur, and how to avoid the damage in the future.
Why Chimney Leaks Shouldn’t Be Ignored?
Unless it’s detected early, chimney leakage can be disastrous. Damages caused by water seepage involve bricks, mortar, and internal flue systems, giving rise to mould growths, structural instability, and expensive chimney leakage repairs. The water inside the chimney system also makes the fireplace less efficient and, thus, less safe.
Signs you shouldn’t ignore:
- A musty odour coming from the fireplace.
- Visible cracks in mortar or chimney crown.
- Damp firebox.
You have to act quickly upon observing any of these indications, as these are all signs of chimney leakage. Knowing the causes of chimney leaks can help save you against extensive damage.
Top Causes of Chimney Leaks
There are so many causes of Chimney leaks. Let’s have a look at a few of them as under:
Damaged Chimney Flashing
Chimney flashing is a kind of metal barrier that seals the place when both the roof and chimney meet. Weathering takes its toll on flashing over time until it starts corroding, cracking, or loosening. In this way, you expose the flashing; it will invite water to enter through cracks when any part of it becomes compromised, which results in leaks. Constant inspection will make sure that these flashings are fit and sealed properly.
Chimney Crown Cracks
The chimney crown is the highest top part of the chimney, where water cannot get inside the flue. Gaps appear at the chimney crown due to weathering, freezing temperatures, or bad installations. It allows water to infiltrate within the chimney. These small cracks can widen over time and allow moisture to penetrate deeper into the chimney structure.
Chimney Cap missing or Damaged
The chimney cap is even one of the most important components that seal the opening of the chimney to prevent rain snow and debris from getting into it. If the chimney cap becomes missing or is damaged, it causes rainwater to enter the flue completely causing moisture buildup and leading to rusting and damage inside. It is a well-known fact that having a solid chimney cap is a cheap and practical measure to avoid leaks.
Worn-Out Mortar and Masonry
Chimneys are constructed of bricks and mortar, which are porous materials. Exposure to the rain, snow, and freeze-thaw cycles over the years deteriorates mortar joints. When the mortar cracks or crumbles, it creates pathways for water to enter the chimney system. Tuckpointing-renewing old, damage-filled mortar with fresh mortar can restore the integrity of the chimney.
Porous Bricks and Lack of Waterproofing
Bricks are naturally porous, so they are strong and durable materials. If the chimney is not waterproof, then during heavy rain, bricks may become moisture-laden which may cause leakages and internal damage. Over a period, moisture absorption leads to deterioration of bricks by causing spalling (flaking) and eventually weakening the entire structure. The application of an effective professional-grade waterproof sealant saves the chimney and extends its lifespan.
Clogged or Re-aligned Gutters
Gutters play a very important role in channelling away water from your roof and chimney. Clogged gutters can lead to pooling water near the chimney, thus increasing the risk of leakage. Have your gutters cleared and aligned.
Condensation Inside the Flue
Inside the chimney, condensation may build up if the flue is improperly lined or poorly vented. This is quite common with modern gas fireplaces. The excess moisture can cause leaks and degradation damage to the chimney over time. The solution is to have a chimney liner installed, which will also enhance efficiency.
Preventing and Fixing Chimney Leaks
Though there are several reasons for the chimney leak to occur, prevention is better than cure. Here are some top tips to safeguard your chimney:
- Schedule Regular Chimney Inspections
Annual inspections from professionals like A Step in Time Chimney Sweeps can get you early detection of any small leaks, or damage to mortar or flashing before a major problem arises.
- Install a Chimney Cap
This is a very cost-effective and simple preventive measure against rain, debris, or the entry of animals into your chimney.
- Waterproof the Chimney
Water cannot be absorbed by any masonry bricks with the application of waterproof sealant on the chimney; thus, stretching its life further.
- Fix Cracks Promptly
Any cracks in the crown, mortar, or bricks noticed should be sealed promptly to prevent the entry of further water.
- Maintain Gutters and Downspouts
Rainwater collects and is directed away from the chimney by proper maintenance of gutters.
- Install Proper Flashing
Ensure that flashings are tightly secured around your chimney which makes them watertight and schedule regular inspections.
