    Hello all.

    Has anyone come across and tried and tested (even unique on the market) product that will seal a gutter joins.

    1_Mastic - almost always fails and too messy
    2_Supplied rubber seals - I have replaced the joins and the supplied seals are not a match for my older half round gutters

    This is an eternal problem - surely there has been something brought to market that resolves leaking gutter joins.

    i used CT1 on my very old cast iron gutters , worked really well, and still going when i left in 2017 and i redid all the joins in 1997
    not used on any of the plastic gutters, in my daughters property we replace the joints that had gone with new sections from wickes - they had been badly mastic and leaked like mad, 1970's property

    Also CT1 can be used in water , so no issue when WET

    is it because you cannot get the gutter profile and replace

    is the gutter actually over the rubber seal , my bangalow had an issue where the new guttering had not been extended into the join enough to clip down on the seal

    There’s specific gutter sealants as well, but I like to replace the rubber seals.
