Brick structures require maintenance to preserve their structural integrity and aesthetic value. One crucial aspect of brick maintenance is repointing - the process of renewing the external part of mortar joints.
What Does It Mean to Repoint Brick?
Repointing is the process of removing old, damaged mortar from the joints between bricks and replacing it with new mortar. This maintenance procedure is essential for preserving the structural integrity of brick buildings and preventing water damage.
Factors Affecting Repointing Frequency
On average, well-constructed brick structures may need repointing every 25 to 50 years. However, this can vary significantly based on a few factors.
Age of the building
Quality of original construction
Exposure to weather elements
Type of mortar used
Maintenance history
How to Know When to Repoint Brick
Recognizing the signs that your brick structure needs repointing is crucial for maintaining its longevity.
Crumbling mortar
Visible cracks in the mortar joints
Loose bricks
Water infiltration
Mortar erosion of more than 1/4 inch
Regular inspections, especially after severe weather events, can help identify these issues early on.
How to Repoint Brick
While repointing is a task best left to professionals, understanding the process can help you appreciate the work involved:
Remove old mortar to a depth of about 3/4 inch
Clean out the joints
Dampen the bricks and joints
Mix new mortar
Apply new mortar using a pointing trowel
Finish and shape the new joints
Allow proper curing time
Tools Needed for Repointing
Chisel and hammer
Pointing trowel
Jointing tool
Wire brush
Safety gear (goggles, dust mask, gloves)
How to Repoint Brick Steps
Brick steps are particularly vulnerable to wear and tear due to constant foot traffic and exposure to the elements. Here's a brief guide on repointing brick steps:
Clean the steps thoroughly
Remove loose mortar from joints
Dampen the bricks and joints
Apply new mortar, ensuring it's well-packed
Shape the joints for proper water runoff
Allow sufficient curing time before use
It's crucial to maintain proper slope on step joints to prevent water accumulation.
How to Repoint a Brick Wall
Repointing a brick wall follows a similar process to general brick repointing, but with some specific considerations:
Work in small sections to ensure mortar doesn't dry before tooling
Maintain consistent joint depth and width
Pay extra attention to corners and edges
Protect newly pointed areas from direct sunlight and rain during curing
How to Repoint a Chimney
We advise you to call the professionals for chimney repair. They are particularly susceptible to mortar deterioration due to their exposure to the elements and heat cycles. If you are insistent on doing it yourself, have experience working at heights, and are familiar with the repointing process, this is how a chimney is repointed:
Ensure proper safety measures when working at height
Inspect for any structural issues before repointing
Use appropriate mortar mix for high-temperature areas
Pay special attention to the crown and flashing areas
Consider applying a waterproof sealant after repointing
Cost to Repoint Brick
The cost of repointing can vary widely depending on several factors:
Size of the area to be repointed
Accessibility of the brick surface
Condition of existing mortar
Type of mortar used
Labor costs in your area
Be Proactive
While repointing is inevitable over time, you can take steps to extend the life of your mortar joints.
Regular cleaning of brick surfaces
Proper drainage around the structure
Addressing water infiltration issues promptly
Applying breathable sealants to protect against moisture
Regular inspections to catch issues early
The Importance of Professional Repointing
While DIY repointing might seem tempting, it's a job best left to professionals. Improper repointing can lead to various unintended consequences.
Damage to bricks
Ineffective water resistance
Aesthetic issues
Potential structural problems
