Steve,
Couple of points: First off you are a newbie, therefore you are going to be very slow, it'll take several months to be really cracking along at a good pace. Now some may get up to speed quicker, and that helps if you are working alongside an experienced pro who can correct and help with technique.
Second point; If this is the first time clean for this house, and you are fastidiously cleaning all of the frames, then it is gonig to take an awful lot longer than subsequent regular cleans.
Third point is price, now if these are UPVC windows, I would say that the price isn't all that far off the mark, it sounds like a house that would take about 25 minutes for one of us window cleaners that have been doing it for donkeys years
But that wouldn't include a thorough clean of the frames.
On repeat cleans the frames will only need a quick wipe over with a clean, damp scrim, so should only add 10 mins or so to the job.
In my area, considering you are using trad methods, windows + frames?....Mmm, maybe £3 more cos of the frames...hard to say without seeing some photo's.
When I took on lads, it would take them at least 3 months of solid work before they were working at a reasonable pace, th begin with, during the first 2 or 3 weeks I would be cleaning 3 windows to their one!
So you will get much, much quicker!!
regards,
Ian.
Oh, on reading the replies on page 2 I see roger (squeaky Clean) Mentioned a £90.00 account, which is the £120.00 account I also mentioned. he claims 3 hours...yeah, right! Lol I'll accept 4 hours! I know cos I did it Yesterday (wednesday 14th)
Rog is a bit quicker than me with Trad stuff, but that was made up with doing the outside with WFP.
Inside is a nightmare, as is the inside of the conservatory, hence the price, but still good money for a mornings work
Regards,
Ian
