did a drive/wall clean. drive was fine, the wall was knackered (check pictures) i explained to the women that it would need re-pointing or maybe even new blocks put in, and she didnt seem bothered and just agreed. now shes moaning, saying she needs to get her wall re-pointed? i was being very carefull when i cleaned the wall as to not damage it further and didnt even try to remove the efflorescence! what do you guys reckon? my fault or what?
