Blocked Gutters — what's actually going on

Water cascading down the wall in heavy rain or dripping behind the fascia.

Common causes

  • Leaf and moss build-up at the downpipe outlet
  • Sagging brackets pulling the gutter off its falls
  • Joint seals perished on old uPVC runs
  • Downpipe routed away from the gulley

How we fix it

  • Full clear-down and water-test of falls
  • Re-space brackets to correct centres so long runs don't sag
  • Re-seal failing joints; replace runs where uPVC is past life
  • Quote leaf-guards as an option where overhanging trees justify them

Our guides on this

Blocked gutters and damp walls: tracing the cause properly

Damp that appears on an internal wall after heavy rain, high up or in a vertical stripe, is usually rainwater from an overflowing gutter or a split downpipe rather than rising damp. Fix the rainwater goods first — it costs a fraction of any damp-proofing treatment and resolves most cases.

How often to clean your gutters (and what happens if you don't)

Clear your gutters twice a year as standard — late November after leaf fall and again in spring. Properties with overhanging trees, common across Hampton, Teddington and Richmond, need three visits a year. A typical semi-detached clearance runs £80–£150.

Leaking gutter joint: causes and fixes

A gutter joint usually leaks because its seal has hardened or moved, the adjoining lengths are misaligned, brackets allow the run to sag, or a blockage keeps the joint under standing water. Repair the cause and test the full run rather than sealing only the visible drip.
