Frequently Asked Questions
How can I tell if my chimney has dangerous build-up?
Professional inspection is essential. Warning signs include slow-burning fires, tar-like odours, and dark staining around the fireplace.
How often should chimneys be cleaned to prevent build-up?
HETAS guidelines recommend at least annual sweeping, with more frequent cleaning for heavily used systems or those burning wood primarily.
What makes the Cre-away treatment effective?
The chemical powder reacts with heat to break down tar and creosote deposits, making them easier to remove during the final sweep.
How can I prevent rapid creosote build-up?
Use properly seasoned wood (less than 20% moisture), ensure adequate airflow, and maintain regular professional sweeping.
