Daughter's house has quite a nice wall - 7 ft high - between garden and road. The top of the wall ise merely brick. A few have "spalled" and the wall is a bit discoloured due to damp soaking down it. Others in the same
1988 development are the same.
I am wondering if there is a way of improving it - Coping Blocks on th etop to shed the rain??? How could the colour of the brichwork be recovered?
Any ideas?
