I live in a semi detached house in Dublin. Recently my neighbour got new PVC gutters and faisias installed by company who was canvassing our housing estate. We still have the old palstic gutters (30 years old) and wooden faisia's. Now when it rains we hear a 'ticking' type noise from the area of the gutters at the rear of the house. Does anybody know can anything be done about this noise?
