BLOCK WALL REPAIR

Block Wall Repair in Ottawa

If your home doesn’t have a poured concrete foundation, chances are it has a block wall foundation—a system of stacked cinder blocks that interlock much like bricks. While these foundations can support more weight than poured concrete and are common in larger homes, they do come with their own set of challenges.

Why Block Wall Foundations Need Attention

The mortar joints between the blocks create hundreds of tiny gaps, and over time, these can allow water, ice, and moisture to penetrate. As water seeps in, it expands and contracts with temperature changes, leading to cracks, leaks, and eventually, a weakened foundation.

How We Repair Block Wall Foundations

Block wall repair depends on the extent and cause of the damage:

• Repointing: For minor issues, we remove and replace cracked or deteriorated mortar to reseal the wall and restore its strength.
  
  

• Structural Reinforcement: In more severe cases, we may add reinforcements like steel columns or wall anchors to redistribute pressure and prevent further movement.
  
  

• Wall Rebuilding: If damage is widespread, a full or partial rebuild of the block wall may be necessary.
  
  

• Cement Fill: For added strength, we can fill hollow blocks with cement.
  
  

• Drainage Improvements: Addressing water intrusion at the source can help prevent future damage.
  
  

Signs You May Need Block Wall Repair

• Cracks in the walls or mortar joints
  
  

• Water leaks or dampness inside the basement
  
  

• Difficulty opening doors and windows
  
  

• Cracks in interior walls or ceilings
  
  

• Bowed or buckled walls—a serious sign that immediate attention is needed
  
  

If you’re seeing any of these issues, don’t wait. What may start as a small repair can grow into a major structural issue.

How Long Does a Block Wall Foundation Last?

The longevity of your block wall foundation depends on:

• The quality of the original construction
  
  

• Local soil and moisture conditions
  
  

• Whether proper drainage systems (like weeping tile) are in place
  
  

• Timely maintenance and repairs
  
  

With proper care, repairs can significantly extend the life of your block wall foundation.

What Does Block Wall Repair Cost?

Most block wall repairs fall between $1,000 and $3,000, depending on the extent of the damage. More intensive work—like structural reinforcement or wall rebuilding—can cost more.

The good news? Some foundation repairs may be covered by your homeowner’s insurance, depending on your policy.
