Step 2 – Remove Damaged Bricks
- You will only be able to remove the damaged bricks from the outside of the chimney, rather than anything in the inside, so using a hammer and chisel, knock out and damaged bricks, and place them to the side. You should keep any bricks that you can, possibly even dividing the bricks so that the damaged half can be thrown away.

Once you have completed the brickwork, you should cover all of the a…
Step 4 – Finishing
- Before you finish the project you will have to check the rest of the brickwork to ensure that there is no more damaged mortar in the surrounding area. Old mortar might chip and crumble, so look out for mortar which crumbles under pressure from your fingers. You can apply a layer of caulk over the surface of the mortar in order to prevent any more mortar from crumbling away.
