The back of this cast iron guttering has completely rusted away & the rain water has been running behind it onto the top of the stone wall. This has led to a serious damp & mould problem inside the property. To remedy this we have removed all the debris from the gutter, thoroughly dried it out & using polyurethane sealed lead to the inside & dressed it onto the stone. This will divert the water into the gutter allowing the wall to dry out. Repairs like this cost a great deal less than replacing the cast iron guttering.
