How do you do it that quick Squeaky........you haven't even got any water Of course I have!
Seriously if you can do a complete clean of a connie in under one hour then i take my hat off to you and all those that follow your lead.
Myself i tend to allow myself a longer amount of time,but then i must be slow as some on here reckon they clean three / four bed semis in 5 - 10 mins whereas i would take at least 15 - 20 mins.....i can only dream of getting quicker
I don't do standard houses in 5-10 minutes. Probably 15 mins most times.
But I certainly don't see a conservatory as much work.
Unless access is awkward it's just another 10 windows with a bit more scrubbing and rinsing.
Usually an hour including the house windows I'd say, so £35-40 all in is better than most straight window jobs..
