Not bad at all. It does need a little read (depending on how correct you want it), e.g. 'Making just about any buildings gutters accessible where scaffolding might otherwise be required.' would be better with a semi colon before 'Making', rather than a new sentence. (i'm not even sure that is a sentence). Also 'buildings gutters' is buildings' gutters, stick an apostrophe in after the 's'.
I would prefer to see a colour pic on the front and something that is more obviously gutter cleaning; maybe close in a bit on the pic. It took me about 2 secs to work out what that pic was about and for me that's too long.
Quite a bit of repetition on the site, that could possibly be condensed. Less is more.
I would sell sizzle rather than the sausage, e.g. rather than your heading 'IPAF' (which is ok) I would have 'We can clean, clear and survey almost any building up to 70 feet'.
Not much on there for high-end residential, e.g. do you cover the whole of London? Can you clean my gutters within a week? Do I have to be in when you clean? The access to the rear of my property is not good, is this a problem?
Also not much about yourself, quality of staff, quality of service a nice bit of smelly bullcrap.
Hope that's helpful.
