Fascia & Soffit Replacement Dublin

A genuine problem in this trade is installers who nail a new PVC board straight over rotted timber underneath instead of removing it first.

It looks finished, it looks fine for a year or two, and then the rot that was never actually dealt with keeps spreading behind the new board until it fails again — except now you're paying to strip out both the rot and the board that was hiding it.

We remove existing boards fully before fitting anything new, specifically so this isn't a problem you discover in three years' time.

This matters more in Dublin than it might elsewhere in Ireland, because coastal salt exposure genuinely accelerates fascia and soffit failure in areas like Clontarf, Sutton, Dún Laoghaire, and Malahide — salt-laden air speeds up corrosion on fixings and degrades cheaper board material faster than it would inland.

If your property sits anywhere near the coast, that's worth factoring into both the material choice and how often it's worth having a roofline check.

These two boards get lumped together constantly, but they do different jobs, and that matters for diagnosing what's actually gone wrong. The fascia is fixed directly to the ends of your roof rafters, running along the roofline edge — it's structural, supporting the bottom row of tiles or slates and carrying the full weight of your guttering, which is bolted straight onto it.

The soffit sits underneath, enclosing the underside of the roof overhang, and its job is ventilation: letting air flow into the attic space while keeping birds, wasps, and vermin out.

Because the fascia carries the entire weight of a full gutter run, a gutter holding standing water from a blockage or bad fall puts sustained extra load on the fascia's fixings — over time, this pulls the board away from the rafter ends, which often gets misdiagnosed as "a gutter problem" when the fascia fixing failing under the extra weight is the actual root cause.

The soffit's failure mode is different: painted-over vents, nesting debris, or physical damage block the airflow it's meant to provide, which shows up as condensation or mould on the underside of the roof deck in the attic — invisible from outside, and easy to miss until someone's up there for another reason entirely.

Every job starts with checking fascia, soffit, and the attached guttering together, since a problem in one area is frequently caused by, or causing, a problem in another — a sagging fascia is often actually a gutter-weight issue, not a fascia defect on its own.

We identify whether the job is a section repair or a full run replacement, remove existing boards completely rather than covering over anything underneath, confirm ventilation is genuinely adequate once new soffit goes in, and re-secure gutter brackets properly to a board that isn't already showing signs of the same fixing failure that caused the original problem.

Scaffolding, property size, and board material are the three biggest cost drivers — a two-storey property needing full scaffold costs more than the same job on a single-storey with ladder access, and thin, cheap PVC board is a false economy that tends to sag or crack within a few years regardless of how well it's fitted.
