Process
- Safety First:Before any work begins, the chimney should be thoroughly inspected to identify any areas of perished or missing mortar.
- Assess Damage:Check the mortar joints for crumbling and gaps, and look for damaged or loose lead flashing.
- Rake Out Mortar:Carefully remove old, damaged mortar from the joints to a consistent depth of approximately 20-25mm using a suitable tool, like a chisel and hammer, being careful not to damage the brick edges.
- Clean Joints:Brush out any remaining mortar dust and debris from the joints.
- Dampen Surfaces:Lightly wet the brick and joints to prevent the new mortar from drying out too quickly.
- Mix New Mortar:Mix a new mortar, typically a sand and cement mix, using a strong 3:1 or 4:1 sand-to-cement ratio for exposed chimneys.
- Apply New Mortar:Trowel the new, sticky mortar firmly into the cleaned joints using a tuck pointer or finger trowel.
- Finish the Surface:Smooth the new mortar to the desired pointing style, such as flush, bucket handle, or weather struck, depending on the location and desired aesthetic.
- Cure the Mortar:Cover the finished work with damp hessian to allow the mortar to cure slowly and prevent rapid drying.
- Inspect Flashing:Examine the lead flashing where the chimney meets the roof for any damage or gaps, as this is a common entry point for water.
- Repair or Replace:Repair any holes or replace the damaged flashing to create a watertight barrier.
- Install Lead Trays:For added protection, a lead tray can be installed within the stack itself to stop moisture from tracking down the chimney.
- Restore Integrity:Proper repointing and leadwork will restore the chimney’s structural integrity, prevent water damage, and ensure the security of the chimney.
- When to Get Professional Help:For more extensive repairs, unstable chimneys, or complex leadwork, it is essential to hire a qualified professional.
- Consider Scaffolding:For larger or more complex jobs, scaffolding may be necessary to provide safe and stable access for the workers.
