If you’ve been dealing with annoying leak-related problems for a while, you might already have some serious damage to your chimney and venting system. But, before we get into that, we’d like to help you understand the potential causes behind these leaks, why they can be so troublesome, and how our team can assist you in tackling this issue.

Troublesome Causes of Chimney Leaks

There are several reasons why your chimney might leak during a rainstorm, and each can cause a range of problems for your home.

✔️ Cracked or Damaged Chimney Crown

A cracked or damaged chimney crown can allow rainwater to seep into your chimney, leading to leaks, water damage, and potential structural issues. It can also encourage water to flow down the outside sides of the chimney, rather than be pushed out and away. And if left unaddressed, these cracks can worsen, causing even more significant problems down the road.

✔️ Faulty or Deteriorated Flashing

When your chimney flashing is damaged or deteriorated, it allows water to infiltrate the gap between your chimney and roof, potentially causing leaks, wood rot, and mold growth in your home. Furthermore, damaged flashing can lead to more extensive roof damage, putting the integrity of your entire home at risk.

✔️ Missing or Damaged Chimney Cap

Without a properly functioning chimney cap, your chimney is left exposed to rain, debris, and small animal/bird entry. Not only can this cause leaks, but it also creates the perfect environment for nesting materials and unwanted debris to build up – which can then result in dangerous chimney blockages.

✔️ Porous Masonry Over Time

Your chimney’s masonry can become porous due to weather exposure, allowing water to seep through and cause leaks. This can lead to more extensive water damage, weaken your chimney’s structure, and even contribute to the deterioration of your home’s foundation.

✔️ Condensation

When warm air from your fireplace meets the cold surface of your chimney, condensation can form and create leaks. If left unaddressed, this excess moisture can cause rust, corrosion, and other damage to your chimney, reducing its lifespan and effectiveness.

  • Chimney Liner Installation: If condensation is causing your chimney leaks, we can help by installing a chimney liner. A liner creates a barrier between the warm air from your fireplace and the cold surface of your chimney, reducing the likelihood of condensation forming and triggering any associated damage.
  • Regular Maintenance: At Winston’s Chimney Service, we understand the importance of regular maintenance to keep your chimney in top shape and prevent leaks. We offer annual inspections and chimney sweeping services to ensure your chimney remains in excellent condition and functions safely and efficiently for the long haul.
