fireplaceWays to Seal Your Unused Chimney Flue

Our team takes one of the three following approaches when sealing unused chimney flue, based on the situation and our clients’ wishes:

  1. Sealing from the peak of the chimney
  2. Sealing from the base of the chimney
  3. Sealing from the fireplace using brick and mortar.

When a chimney is sealed from the peak or base, this is easily reversible, making it easier to change your mind in the future, should you later desire to use your chimney.

In cases when chimneys are sealed from the fireplace using brick and mortar, this can still be reversed, but it is more complicated. This type of project would require some demolition and a high level of precision to reverse, making this kind of sealing a larger decision.
