Handful of proof-reading errors:
In addition to our window cleaning services we also offer conservatory cleaning, gutter cleaning and clearance
as well as fascia, soffit, barge board and cladding cleaning.
I'm getting a very oddly placed carriage return between "clearance" and "as"
"complement" not "compliment" - different meanings. Used twice on page one.
"...if specifically required; but our cleaning methods also incorporate..." - you need either the semicolon or the "but"; not both.
"...wish to enhance it's appearance for potential buyers..." no apostrophe in "it's" in this sentence.
"...notice when its dirty..." does need an apostrophe.
Sorry if they seem picky but to me it does make a difference and I may not be alone.
However, the overall comment I'd make is in line with one above - it looks a little bit "anaemic". I have no idea (obviously) what you've used to design it but is there a way of putting a background image behind the site? Even a flat wash of colour or a graded colour might help.
