just recently had house repointed , ground then pointed back up , a mucky expensive job but well worth it , all work done off ladders ,some builders/roofers may do your job over a weekend when no HS staff are working , if you find one ?maybe split the difference for the cost of scaffolding and pay them £500 if they are prepared to do that ? No point me giving you the number of the lads who did mine , been waiting over a year , good luck,
