This is the problem I have with the online calculator or having a set price for each window:
e.g (average prices taken from online calculators)
6 x Velux @ £2 = £12
12 x Ground Floor @ £1 = £12
13 x 1st Floor @ £1.50 = £19.50
4 x 2nd Floor @ £2.00 = £8.00 (3 x front 1 x side)
5 x French Doors @ £2.00 = £10
Total £61.50
Doubt I would get the job at this price.
I normally price on how long it would take to clean, if I'm cleaning other properties near by and how regular the cleans are etc:
There's a large degree of common sense when quoting any kind of job and like I said it's an art form in it's self into getting it right.
The post was interesting and has always, thrown up a wide divide in opinions. I probably used it to consolidate the price I had in mind originally, but always willing to learn.
Thanks again
