Why gutters fail here
London's guttering problem is rarely one big storm — it's near-constant light rain combined with a huge stock of Victorian and Edwardian terraces still running original cast-iron guttering. Cast iron rusts and cracks at the joints in a way modern uPVC and aluminium don't, so a lot of London gutter work is really about deciding whether to repair or replace an older system.
- Rainfall pattern
- Frequent light rain spread through the year rather than concentrated storms, with moss growth on north-facing and shaded roof sections a persistent side effect.
- Freeze risk
- Low freeze risk

What it costs in London
Local pricing note (GBP)
Above the national average in central boroughs, driven by terraced-house access difficulty and the higher cost of cast-iron repair versus standard uPVC work.

Should I repair or replace cast-iron guttering on a London terrace?
It depends on the extent of rust: surface rust and a cracked joint or two are often repairable, but if multiple sections are pitted through or the brackets are failing, replacement with cast-iron-effect uPVC usually costs less over time than patching an old system section by section.
Why does moss build up on London roofs and guttering?
Near-constant light rain keeps shaded and north-facing roof sections damp for long stretches, which is exactly what moss needs to establish. Once moss sheds into the guttering, it holds even more moisture against the metal and accelerates rust on cast-iron systems specifically.
How often should London homeowners clean their guttering?
Twice a year is standard for most properties, with terraced houses under mature street trees needing a check after any strong autumn wind, since London's plane trees drop debris unevenly through the season rather than all at once.
