I have been looking to buy a ladder to clean the upstairs windows but would like it long enough to clean the guttering out. I have seen a 22 foot triple extension ladder on screwfix but was wondering if it would be long enough as i don't know what slope the ladders should be at. From the top of the guttering to the floor is 18 foot long.

To do it by the book you should never work off a ladder whose top is below shoulder height which means will need a 'ladder stand off' which will mean that the ladder leans against the wall below the facia and guttering but 'stands off' from the wall so it can extend above the guttering without leaning on the guttering all of which means you will need a slightly longer ladder. However, if you intend to lean it against the wall below the facia and try to work from there contrary to the above then yes, it will be long enough.

Remember to check the maximum load the ladders will take. The 100Kg ones are no good. You want the heavy duty ones with a max load of 150Kg.

By the way, I bought my triple extension aluminium ladders from an ebay shop called lewis ladders. It was a great ladder at a great price but he did not sell stand offs at the time (he may do now, I don't know as it was a couple of years ago.) so I had to buy that elsewhere.

A 22ft triple is one very big ladder

A 12 ft double would be more cost affective.

Surely the figure he quoted was fully extended as he was asking if it would reach up to an 18ft high gutter?

buy a stand-off.

you will be glad you did.

Yeah i did mean 22 foot fully extended

Hi as a rule of thumb ..i think its ...for every three foot high its one foot out....so at 18ft it would be 6ft out...

which is just under 19ft

you could hire one, and hire the stand off and ,spurs, as well, with stand off at the top and spurs at the bottom the ladder will go no where, and i should know, been working off of ladders for 25 years, took me three falls to get the spurs, wouldnt be withoput them now

Enjoy

as mike said go for one that will take at 150kg. that should take a lot of standing and carrying weight unless youve got a big beer belly like me ;)
