The PVC guttering (Osma "Squareline") around my property is leaking at several places wherever there is a join or connection. It would seem that the clip, which pulls the guttering down onto a soft rubber gasket is not doing so sufficiently to make a watertight joint. The components are of course designed to allow for the thermal expansion and contraction so I am reluctant to start applying mastic which I feel will not survive the thermal movement. Any suggestions from our knowledgeable ABers would be appreciated. Many thanks.
The seals can become perished and softer over time. I would just replace the jointers. They are easily available and it's a simple job. Far better than trying to resell them
Thanks for your response Builder, I hoped you would pick up on my query. By jointers do you mean the rubber gaskets, they're available separately are they?
