My gutter has an annoying drip from a join. It's now leaving a damp stain on the house.
It's standard, semi-round, black plastic (Marley?) that's been there for forty-odd years. I've had a couple of goes at taking it down, cleaning the joint and using a mastic type compound called roof and gutter sealant. It still drips.
It all looks in good condition and well supported.
Any suggestions, or should I renew the whole lot?
