Gutter repairs in Dublin typically cost between €500 and €1,900, depending on how much of the run is failing, the material, and the height and access. Most jobs are leaking joints, sagging brackets or a lost fall, fixed in a single visit with a 10-year written guarantee. Free survey, no call-out fee.
Summary
- Repair prices start at €500 for a couple of leaking joints; most Dublin jobs land between €1,000 and €1,900; cast iron or multi-run work runs €1,900–€3,000.
- Three faults account for most calls — failed joint seals, pulled or sagging brackets, and a lost fall that dams water at one point in the run.
- Overflowing after cleaning usually means the profile is undersized — common on 1970s estates like Tallaght and Coolock where 112mm half-round can't shift the roof area, and no repair fixes it.
- We repair before we replace and say so plainly; a single failed joint or one sagging bracket is a repair, not a reason to renew an elevation.
- Every repair carries a 10-year written workmanship guarantee; the Lifetime Leak Guarantee applies only to full replacements.
- Free survey, no call-out fee, written breakdown before anything is signed, and the run flushed with water before we leave.
What actually fails on a Dublin gutter
Most repair calls to a Dublin house come down to one of three faults, and telling them apart on the phone is guesswork — you have to go up and look.
Failed joint seals. The rubber gaskets in a uPVC union harden over about fifteen to twenty years, especially on south-facing runs that take direct sun. Water then drips from the joint onto the fascia below, staining the board and often rotting it before the homeowner spots the leak. A joint reseal, or a new union where the plastic itself has gone brittle, resolves this.
Sagging runs and pulled brackets. Brackets fixed to a fascia that has softened lose their grip, and the gutter drops between fixings. Water pools at the low point, weight increases, and the next bracket goes. On the older uPVC common in Cabra, Crumlin and Terenure, brackets often need renewing at closer centres than the original installer used.
Lost fall. A run should drop roughly 3mm per metre toward the outlet. When brackets shift or a section is knocked, the fall reverses at one point and water dams there — you'll see a permanent green stripe on the inside of the gutter. Resetting brackets to a proper fall clears it.
Coastal exposure changes the maths. In Howth, Sutton, Malahide, Clontarf, Sandymount and Dun Laoghaire, wind loading pulls brackets away from gables that would sit tight inland. Bracket spacing matters more there, and a repair that holds in Tallaght may not hold on an exposed sea-facing elevation.
How much do gutter repairs cost in Dublin?
Gutter repair in Dublin starts at €500. Most repairs land between €1,000 and €1,900. Cast iron and multi-run work runs €1,900–€3,000. What moves the price is how much of the system needs work, the material, the height and the access — not the metreage of the house.
| The job | Typical cost |
|---|---|
| Small — a couple of leaking joints on one run | €500 – €800 |
| Typical — sagging run re-aligned, brackets renewed, joints re-sealed, a downpipe | €1,000 – €1,900 |
| Extensive or cast iron — multiple runs, period property, welding and restoration | €1,900 – €3,000 |
Figures are indicative and confirmed free after a site survey. A short run on a Rathmines redbrick with original cast iron can cost more than a long run of uPVC on a Clonsilla semi — material and access outweigh length every time.
For anything beyond a targeted repair — a whole elevation that sags between every bracket, or a run that overflows along its full length even when clean — the honest answer is a full gutter replacement rather than piecemeal patching. Our Dublin guttering hub sets out where repair stops making economic sense.
When a repair will genuinely hold — and when it won't
We repair before we replace, and we say plainly when a repair won't do. The rules are boring but they hold up:
- One or two failed joints on an otherwise sound run — repair.
- A single sagging section between two brackets, with a sound fascia behind it — repair.
- A short damaged length knocked by a ladder or a falling branch — repair.
- A run that sags between every bracket — the whole run has passed its life, replace.
- uPVC that cracks along its length when handled — UV embrittlement, replace.
- More patches than gutter — the maths has stopped working.
- Overflows along the whole run when perfectly clean — the profile is undersized, upsizing to 125mm deep-flow is the only fix.
The last one catches out a lot of homeowners. On many 1970s Dublin estates — Tallaght, Clondalkin, Coolock, Ballymun — the original 112mm half-round is genuinely too small for the roof area it serves. Cleaning it doesn't help. Resealing joints doesn't help. The gutter has to be upsized, and that is a replacement conversation.
What the housing stock predicts
Dublin's age bands each fail in their own way, and the address usually tells us what we're going to find before the ladder goes up.
Georgian and Victorian redbrick — Rathmines, Phibsborough, Drumcondra, Portobello, Ranelagh. Original cast iron, often worth saving. Surface rust that has pitted the section is repairable with preparation and painting; rust that has gone through the base is not. Repair sections are welded in to match the profile rather than a length being swapped for uPVC that will look wrong on the elevation.
1930s and 1940s semis — Cabra, Crumlin, Terenure, Clontarf. First-generation uPVC fitted decades ago, now brittle from UV and with joint seals hardened past resealing. Brackets often need renewing, and the fascia behind is worth checking while the gutter is off.
1970s estates — Tallaght, Clondalkin, Coolock, Ballymun. Standard 112mm half-round, frequently undersized. The call is usually "it overflows in heavy rain" and the honest answer is upsizing rather than another clean.
Newer developments — Citywest, Clonsilla, Adamstown. Generally sound. The calls are blockages, the occasional bracket, and the odd outlet that was never quite right from new.
If the gutter comes off and the board behind it has gone soft, there's nothing for a new bracket to bite into. Gutter, fascia and soffit then get done in one visit — more work on the day, considerably cheaper than doing it twice.
The emergency path
An overflowing gutter in heavy rain that is tracking down a wall or into a ceiling isn't a scheduled job. Say so when you call and we prioritise it — same-day where the diary allows. Photograph the overflow before anything is done, especially if a named storm has passed through; storm damage to guttering is usually covered under the storm peril of a home insurance policy, subject to the excess, and a written report from a contractor helps the claim.
Wear-and-tear failures, age-related joint decay and blockages are not covered — insurers distinguish sharply between a storm event and a gutter that had reached the end of its life anyway.
How the job actually runs
- You call (01) 265 8463 or send the form. Mon–Sat 08:00–18:00. The form goes straight to the office rather than into a queue.
- We arrange a look. Free, no call-out fee. We go up and inspect rather than pricing from the ground — the difference between a failed joint and an undersized profile isn't visible from a driveway.
- A written quote. Breakdown of what's being done and what it costs, with the guarantee terms in writing before anything is signed.
- The work. Directly employed crews — our own people, never subcontracted. Most repairs are a single visit.
- We flush and check. The run is tested with water before we leave, so you know it clears rather than being told it does.
- The guarantee is handed over. 10 years in writing on the work.
