Terraced houses can be great or horrifc.
They can take less than 5 minutes to clean the issue is the wrong ones can take you longer to get the hose round than clean them....I have quite a lot on my round but have weeded many out over the years and will only take on certain ones.
Yes. I agree. I have a row of 5 1970's terraces (no bays) which I park at one end at the back and run my hose along the fronts and then the backs. They are £20 a pop (including any extensions and rooflights.) If I am brisk and don't yack (one of the custies is a very trim and pleasant middle aged lady who makes me a drink when she is home so that might add five minutes
) I can do them all in an hour including putting pre-written slips though and reeling in and out.
So £100 an hour when I want to and about an hour and ten if working leisurely.
In contrast I have two house in a similar terrace on the same estate - so £40 - but that takes 40 minutes due to how they are spaced out. But even at £60 per hour that's fine.
Where it gets a little tricky is when you only have one per van move. Then it's possibly 25-30 minutes for £20 (or maybe £22.00) because it is on its own.
