Cast Iron Gutter Repairs
Cast iron gutters on Dublin's Victorian and Georgian houses can last over a century if the joints are kept sealed and the iron painted. A joint cleaned back, resealed and painted is from €60; a badly rusted run is restored or replaced, €2,500 to €7,500. On a protected structure, repair like for like.

What goes wrong with cast iron
- Joints: the bolted joints dry out and rust. Water then rusts the iron from the inside.
- Cracks: a length that's been standing full of water and frozen can crack along the bottom.
- Paint: once the paint goes, rust starts. The inside of the gutter needs paint too.
- Brackets: rusted brackets or rafter spikes let a heavy length drop.
Period houses and protected structures
18,837 households live in Pembroke, where 31.5% of homes were built before 1919; Rathmines, Clontarf and Dún Laoghaire are much the same. Many are protected structures or in an architectural conservation area. Repairing like for like, in cast iron, is normally fine; changing to plastic or changing the look can need planning permission. Check with your council, for example Dublin City Council, before anything is swapped.

Questions people ask
Can cast iron gutters be repaired?
Yes, almost always. Joints resealed, a cracked length replaced in iron, the whole run painted inside and out.
Can I replace cast iron with plastic?
On most houses, yes. On a protected structure or in a conservation area, ask the council first: it can need permission.
How often should cast iron be painted?
Every few years, inside and out. Paint is what stops it rusting.
Is restoring cheaper than replacing?
Usually. Full restoration or replacement of a run is €2,500 to €7,500, much of it access and scaffolding.
