Hello,

My gutter is about 9 metres long. A chap went up a ladder to clean it
out and said the seals were beginning to perish. He said they were not
a problem now but might be in the future, but he didn't say how long
into the future. Is it just a matter of replacing the joins or is it
best to rip the whole length down and replace whilst we have some nice
weather? If we did replace the gutter, what is the longest single
length you can buy? I see Screwfix and toolstation only sell 3 metre
lengths, I presume because of transport considerations. A builder said
you can get 4 metres lengths but even those would require three joins.

Thanks,
Stephen.
