As chimney specialists serving Cape Cod and the surrounding Massachusetts communities for over 30 years, we’ve seen firsthand the dangers and damage creosote can cause. Undoubtedly, keeping your chimney clean and safe is more than just a routine, it’s vital to protecting your home and loved ones.
So, what does cause a creosote buildup?
What is Creosote and How Does it Form?
Creosote is a black, tar-like substance that forms when wood is burned in a fireplace or wood stove. As smoke travels up the chimney, it cools and condenses, leaving behind sticky deposits. These deposits are creosote. The more often you burn wood, especially unseasoned or green wood, the more creosote builds up.
There are three stages of creosote buildup, each more dangerous than the last. First-degree creosote is light and flaky. Second-degree is more tar-like and sticky. Third-degree creosote is the most severe, as is hard, glassy, and incredibly difficult to remove. This last stage is also the most flammable, and if left untreated, it can ignite and cause a chimney fire.
Factors that contribute to creosote buildup include:
- Burning unseasoned or damp wood
- Poor air flow or restricted draft in the chimney
- Infrequent chimney sweeping
- Burning fires at low temperatures for long periods
Why Creosote is a Serious Hazard
The presence of creosote isn’t just a maintenance issue, it’s also a safety hazard. When creosote accumulates in your flue, it increases the risk of a chimney fire. These fires can spread rapidly, putting your home and everyone inside at risk. Beyond that, a blocked chimney can cause carbon monoxide and smoke to back up into your home, endangering your health.
Regular chimney inspections and sweeps are essential to keeping your chimney safe. If it’s been more than a year since your last inspection, or if you’re noticing strong odors, poor draft, or smoke indoors, you should really schedule one.
