Gutter repairs — leaks, joints & sagging
In short
Most gutter faults are one of three: a perished joint, a bracket that has let go, or a section that has dropped and no longer falls to the outlet. All are repairable, and all cost a fraction of the damp and rot they cause if they are left.
Also called: Leaking gutter joint · Sagging gutter · Gutter dripping · Gutter came away from wall
Signs you need this
- A steady drip from one point in the gutter during rain
- A vertical stain or green stripe on the wall below a joint
- A section of gutter visibly sagging or out of line
- Gutter pulled away from the fascia at a bracket
- Rust streaks on the wall behind cast iron guttering
- Water getting behind the gutter rather than into it
Guttering fails in a small number of predictable ways, and knowing which one you have decides whether it is a twenty-minute repair or a replacement run.
Joints go first on plastic systems. The rubber seal in a union bracket perishes and hardens, and the joint starts weeping — usually as a steady drip in one spot that stains the wall below in a neat vertical line. New seals or a new union will fix it, provided the gutter itself has not distorted, and it is a genuinely quick job.
Brackets are the second. They rust, they pull out of soft fascia timber, or they were spaced too far apart in the first place — plastic gutter is not stiff and needs support at close centres, particularly where snow can load it. A gutter that has come away at one point puts extra load on its neighbours, so it tends to progress along the run once it starts.
The third is fall. A gutter is hung to a slight fall so water runs to the outlet, and when a section drops it holds water permanently instead. That standing water is heavy, which drags the section down further, and it is why a gutter that holds water when clean is a repair rather than a cleaning job. Re-hanging a run to a correct fall is straightforward and it stops the cycle.
Cast iron is its own conversation. It rusts from the inside and from the back where nobody looks, and the first sign is often staining on the wall behind rather than a visible hole. Sound cast iron can be de-rusted, repaired and repainted and will go on for decades, and on a period property that is usually the right answer both practically and visually. Where it genuinely has gone, cast-effect aluminium looks correct and needs no painting.
The reason any of this is worth doing promptly is what sits directly behind the gutter: the fascia, the rafter feet and the wall plate. A gutter leaking backwards rather than forwards puts water straight onto those, and rotten rafter ends are a considerably larger job than a new union bracket. The repairs that are cheap are the ones done early.
What the job covers
- Failed seals and union brackets replaced
- Brackets renewed and spaced correctly for the system
- Runs re-hung to a proper fall to the outlet
- Cast iron de-rusted, repaired and repainted where sound
- Fascia and rafter feet behind the gutter checked for rot
- Eaves felt drip checked, as water behind the gutter often starts there
What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your roofer has to honour it. On roofing it would also be close to meaningless: access is often the biggest single factor, and it varies enormously house to house. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
Can a leaking joint be fixed or does the run need replacing?
Usually fixed. A perished seal in a union bracket is a quick swap, and that accounts for most plastic gutter leaks. Replacement becomes the answer when the gutter itself has distorted, gone brittle with UV, or when so many joints are failing that doing them one at a time costs more than a new run.
Why does water get behind my gutter instead of into it?
Often it is the eaves felt rather than the gutter. The roofing underlay should overhang into the gutter so water running down it discharges correctly; when the drip edge has rotted away, that water goes behind instead — straight onto the fascia and the rafter feet. Eaves support trays fix it, and it is a small job compared with the joinery it prevents.
Is cast iron worth keeping?
Generally yes, if it is sound. It can be de-rusted, repaired and repainted and will run for decades more, and on a period house it looks right in a way plastic does not. The cost is that it needs repainting periodically. Where it has genuinely corroded through, cast-effect aluminium gives the same appearance with no painting.
Why has my gutter sagged?
Either the brackets have failed or the fascia they are screwed into has softened — and often both, because a leaking gutter rots the fascia which then stops holding the brackets. That is why a sagging gutter usually gets the fascia checked at the same time rather than being re-hung onto timber that will let go again.
