PVC Gutter Replacement in Cork

*When PVC guttering has reached the end, what size to fit on a Cork house, and what a full replacement actually costs*

PVC gutter replacement in Cork is usually the right call once a run has sagged, cracked at the joints, or started overflowing in heavy rain despite being clean. For a standard semi-detached Cork house with 15 to 20 metres of guttering, a full uPVC replacement runs €1,000 to €1,400 fitted, including removal of the old system, new brackets, downpipes and outlets.

When should you replace PVC gutters on a Cork house?

PVC guttering fitted in the 1980s and 1990s is now at the end of its service life on a lot of Cork estates, from Bishopstown and Wilton out to Carrigaline and Glanmire. The plastic goes brittle in UV, brackets fail, and joints that have been patched twice start weeping again within a season.

The honest test for replacement is simple. Replace the run when the gutter is failing along its length rather than at one point: multiple joints leaking, the back edge pulling away from the fascia, sagging that returns after re-alignment, or hairline cracks running through the plastic. If the fault is localised — a single joint, one loose bracket, a cracked outlet — a repair is the right call and we'll quote it that way.

Overflowing in heavy rain, when the gutter is clean, usually means the system is undersized for the roof or the fall has gone. Both are a replacement job, not a patch.

Can PVC guttering be repaired instead of replaced?

Often, yes. A couple of leaking joints on one run is €500 to €800 to put right. Where repairs are starting to come round every year, where the plastic itself is cracking, or where the brackets have corroded and pulled the run out of line along most of its length, patching buys a season and costs you twice. In those cases a full PVC gutter replacement is the cheaper decision over three years.

What are the standard sizes of PVC guttering in Ireland?

Irish housing uses two common PVC gutter sizes:

• 112mm half-round — the standard domestic size on the vast majority of Cork semis, terraces and bungalows built from the 1970s onward. Paired with a 68mm round downpipe.
• 125mm deep-flow (sometimes called high-capacity) — used on larger roofs, long single runs, dormers and houses with heavy rainfall intake. Paired with a 68mm round or 65mm square downpipe.

Square-line profiles (around 114mm) also appear on some 1990s and 2000s estates. They're not interchangeable with half-round — the brackets, outlets and downpipes are a different profile and have to match.

Is 112mm guttering standard? Yes. 112mm half-round is the standard domestic PVC size in Ireland and what you'll find on most Cork houses unless the roof is unusually large or the previous owner upsized it.

How do I know what size PVC guttering I have?

Measure across the top of the gutter from the front lip to the back edge with a tape. 112mm (around 4.5 inches) is standard half-round. 125mm (around 5 inches) is deep-flow. If the profile is squared off rather than curved underneath, it's square-line. Take a photo of the end of the gutter and the downpipe where it meets the outlet — the shape at that junction tells you the profile immediately, and we can confirm the exact fit on survey.

Do I want 5-inch or 6-inch gutters?

In Ireland the practical choice is 112mm (roughly 4.5 inches) half-round or 125mm (roughly 5 inches) deep-flow. True 6-inch systems are rare on domestic work here and usually only specified on commercial roofs or very large detached properties. On a Cork semi, 112mm is almost always correct. We'd upsize to 125mm deep-flow where a long run drains to a single downpipe, where a dormer or extension pushes more water onto one length, or where overflow has been a recurring problem.

What does PVC gutter replacement cost in Cork?

Across Munster, guttering runs €50 to €90 per metre installed. uPVC sits at the lower end at €50 to €65 per metre fitted. The figures below are our indicative ranges from real quotes — confirmed in writing after a free site survey.

House type	Typical runs	uPVC replacement installed
Standard semi-detached	~20 metres	€1,000 – €1,400
Larger or detached	~50 metres	€2,900 – €3,600

Those figures include removing and disposing of the old system, new brackets, downpipes and outlets. A large or complex property can run higher. What moves the price within the range: length and height of the runs, number of downpipes, access (scaffolding versus ladders versus a tower), and whether the fascia behind needs attention at the same time.

If the timber fascia and soffit behind the gutter is rotten, replacing the gutter without dealing with the boards is a false economy — the new brackets end up fixed into soft timber. Most Cork PVC replacements we quote on 1980s and 1990s housing stock include at least some fascia work, and we flag that honestly on the survey.

For reference, our overall gutter replacement spread across 32 real quotes was €1,107 to €12,689, with a median of €3,652 — that spread covers aluminium and cast-iron work as well as PVC on everything from small terraces up to large period properties.

What are two common problems with soffits and fascia on a Cork gutter replacement?

The two that come up on nearly every survey:

• Rotten timber behind the gutter. Years of a leaking joint or an overflowing run soak the fascia from the back. By the time the paint is lifting at the front, the timber behind is already gone. Painting over it traps the moisture and the rot keeps going underneath.
• Birds and vermin in the soffit. Once the soffit boards warp or a corner lifts, starlings and squirrels get into the eaves. We bird-proof as part of the replacement and keep the roof ventilation working.

Full uPVC fascia, soffit and gutter replacement is quoted together where that's the right call — the before-and-after on a Cork terrace is dramatic and the new system is maintenance-free timber-wise.

What types of gutters are used in Ireland?

Three materials cover almost all domestic work:

• uPVC — the standard on modern Irish housing. Light, affordable, 25 to 30-year lifespan with good brackets. The sensible answer on most Cork estates.
• Aluminium (including marine-grade) — used on exposed coastal properties around Cobh, Kinsale and Clonakilty where salt eats standard fixings, and where a longer lifespan is wanted without the cost of cast iron.
• Cast iron — used on period and conservation work in Cork city, often required by Cork City Council on protected structures and in architectural conservation areas. 80+ year lifespan when maintained.

Seamless aluminium (formed to length on site) is a fourth option but we don't fit it. If seamless is specifically what you're after, you'd need a specialist for that.

Frequently asked questions

When should you replace the gutters on your house? Replace when the system is failing along its length rather than at one point — multiple weeping joints, sagging that returns after re-alignment, cracks through the plastic, or overflowing in heavy rain when the gutter is clean. One leaking joint or a loose bracket is a repair, not a replacement.

What are two common problems with soffits and fascia? Rotten timber behind the gutter from years of leaks, and birds or vermin getting into the soffit once boards warp. Painting over rotten timber traps moisture and the rot continues underneath, so we'll say plainly when the boards need to come off with the gutter.

What are the different types of gutters used in Ireland? uPVC on most modern homes, aluminium (including marine-grade) on exposed coastal properties, and cast iron on period and conservation work. Seamless aluminium is a fourth option but needs a specialist.

Is 112mm guttering standard? Yes. 112mm half-round is the standard domestic PVC gutter size in Ireland and what sits on most Cork houses.

What are the two common gutter sizes? 112mm half-round for standard domestic work, and 125mm deep-flow for larger roofs or where rainfall intake is heavier. Square-line profiles around 114mm appear on some 1990s and 2000s estates.

What size is standard size PVC guttering? 112mm half-round, paired with a 68mm round downpipe. That covers the majority of Cork semis, terraces and bungalows.

How do I know what size guttering I have? Measure across the top of the gutter from the front lip to the back edge with a tape. 112mm is standard half-round, 125mm is deep-flow, and a squared-off profile underneath is square-line. A photo of the gutter end and the downpipe outlet confirms it.

Do I want 5 or 6-inch gutters? On an Irish domestic roof, 112mm (around 4.5 inches) or 125mm (around 5 inches). True 6-inch systems are rare here outside commercial work. We upsize to 125mm deep-flow where a long run drains to one downpipe or where overflow has been a recurring problem.

What are the standard sizes of PVC gutters? 112mm half-round and 125mm deep-flow are the two domestic standards. Square-line (around 114mm) is the third profile you'll see on some estates. All three use a 68mm downpipe.

How much does PVC gutter replacement cost in Cork? A standard semi with around 20 metres is €1,000 to €1,400 installed in uPVC. A larger or detached house with around 50 metres is €2,900 to €3,600. Figures include removal of the old system, brackets, downpipes and outlets. Free written quote after a site survey.

Is the quote free, and is there a deposit? Yes, the survey and written quote are free with no obligation. On jobs under €10,000 — which almost all PVC replacement work is — there's no deposit; you pay on completion.

What guarantee comes with a PVC gutter replacement? 10 years in writing on the workmanship, plus the Lifetime Leak Guarantee on the replaced run, with manufacturer warranties on the materials on top. It's automatic and stated on the quote.
