Chimney Foundation

Sturdy chimneys help keep a home’s roof and walls secure


Chimneys are highly vulnerable to shifting soil and changes in weather and terrain conditions. Their vertical structure and semi-detached relationship to a home's support system put them at risk of destabilization over time. However, not all leaning chimneys are caused by foundational issues.*

  • Leaning chimney (away from house)
  • Roof leaks around the chimney
  • Misaligned chimney blocks
  • Mortar loss
  • Separation between chimney and exterior wall

*Cantsink fixes chimney problems directly related to foundational issues.

Sinking, unbalanced chimneys pose many hazards to the structural integrity of a house. A chimney leaning away from your house can create costly roof leaks and exterior wall openings that offer opportunity for pest invasion. It also can create a fire hazard from sparks that escape through chimney cracks. If signs of instability are left unaddressed, a chimney can collapse entirely and cause serious property damage.

  • Unstable soil under chimneys
  • Water incursion under or around chimneys
  • Inadequate or changing structural composition under or around the chimney
