A pair of semi's, me & my neighbour. As both properties are on the level (3 tiered houses), our gutting runs straight across both at each level. On my side the gutters are clean & clear, on the other half they're 3/4 full of silt/moss. Now, when we have a good storm, my side gets overloaded & I've started to get watermarks internally. The houses being so tall, it's not a job you can tackle from a ladder. I've done mine when I've had scaffolding up to repaint. The other house is the village vicarage & the church doesn't appear interested in doing anything about it. Nothing's happened in over a year of my mentioning it. I really want them to clear out their side. Any ideas?
