All
My 15 (ish) year old guttering is leaking at the joints.
Based on some Googling about, it appears to be Osma squareline but I think they've changed the design. the rubber seals on mine are 10mm width and the new stuff seems to be substantially wider (with a corresponding wider recess to fit it in.
Does anyone know if the old seals are still available or would it be a simpler task to just replace the joints?
Thanks
