Why didnt they ask you?
That looks like a nice area I thought you lived on the Chatsworth!
He asked me to unblock his drain in November, told him I haven't got time, which I didn't. We were flat out and always are. Anyone else gets told the same for drains, we don't do emergency drain jetting, I either sub it out to the lads that do or commercial give it my bro in-law with his big vac tanker. He asked me again weeks later, he got the same response. Maybe he thought there's no point in asking me.
I wouldn't mind though the boys at Cleanpoint do this every day. I would have had it scaffolded. Cherry picker would be a nightmare as you'll be moving it every time a car wants to pass. I would have declined the job probably. Brick cleans no longer interest me. Paving cleans and gum keeps us busy.
