Why is installing a chimney so expensive?

Installing a chimney can be a significant job. Costs can easily run into the thousands, depending on the type of chimney, height, materials and access requirements.

What is the 3-2-10 rule for chimneys?

The 3-2-10 rule is a simple guideline used to ensure safe chimney height for proper draught and fire safety. In short, your chimney installation should:

Extend at least three feet above the point where it passes through the roof
Be at least two feet higher than any part of the building within a ten-foot radius

Hire an experienced chimney installer and they'll calculate all of this for you as part of the design.
