9 Signs Your Gutters Need Repair (or Full Replacement)

By the Gutters NW crew · Updated October 20, 2026 · 5 min read

Quick answer

Gutters need repair when you see isolated leaks at seams or corners, a sagging run, or a downspout pulling loose. They need replacement when leaks are widespread, steel gutters are rusting through, the fascia behind them is rotting, or the gutters overflow even right after cleaning because they are undersized.

Signs a repair will fix it

  • Dripping at one or two corners or end caps after rain stops
  • A single run sagging between hangers
  • A gutter pulled a few inches away from the fascia in one spot
  • A crushed elbow or a downspout hanging loose from the wall
  • Standing water in one section because the slope is off

Most of these are fixed in under an hour. Expect repairs to start around $125, with multiple fixes bundled into one visit.

Signs it is time to replace

  • Leaks at many joints because the gutters are sectional and the sealant has failed throughout
  • Rust holes or flaking inside older galvanized steel gutters
  • Soft, dark or crumbling fascia boards behind the gutter
  • Gutters that overflow during storms even when freshly cleaned

Why undersized gutters are common here

Many older homes were built with 4-inch or narrow 5-inch gutters. Modern roofs shed water faster, and Northwest storms can drop a lot of rain in a short window. Steep roofs and valleys concentrate that water at one corner. Upgrading to 6-inch seamless gutters with larger 3x4 downspouts solves overflow that no amount of cleaning will fix.

Repair or replace: how we decide

We water-test the system, photograph every problem, and give you the repair price and the replacement price side by side. If repairs are under about a third of the replacement cost and the gutters are sound, repair usually wins.
