Installers fitting new white fascia boards along a bungalow roofline

Fascias and soffits, fitted right

Rotten boards replaced with clean uPVC by vetted local installers. Get up to three free quotes in 60 seconds.

Quick answer: full fascia and soffit replacement on a typical UK semi-detached house costs £1,200 – £2,800 in 2026, or £60 – £120 per metre supplied and fitted in uPVC. Combined with new guttering, budget £1,800 – £3,600.

Fascia and soffit replacement strips tired or rotten boards back to the rafter ends and fits new uPVC that will not rot, peel or need painting. It matters more than it looks: the fascia carries your gutters, and the soffit ventilates your loft, so when either fails the problems spread well beyond flaking paint.

What the service covers

  • Full replacement: old boards stripped to the rafter ends, timber behind inspected and treated, new uPVC fascias and soffits fitted.
  • Vented soffits: new soffits with built-in ventilation, or over-fascia vents, restoring the airflow lofts need.
  • Capping: new uPVC fixed over existing boards, a legitimate budget option over sound, dry timber only.
  • Combined guttering: new gutters hung on the new boards in the same visit, since the brackets fix to the fascia and the old gutters come off anyway. See our guttering service.

When your boards need replacing

Flaking paint and soft timber are the obvious signs: if a screwdriver pushes into the board easily, rot is established. Sagging or leaking gutters often trace back to failing fascias losing their grip on the brackets. Birds or wasps getting into the roof usually means gaps in decayed soffits, and damp rafter ends or a mouldy loft point at water tracking behind the fascia or blocked ventilation. Any of these means the boards are past cosmetic fixes.

How the work runs

A whole-house replacement usually needs scaffold, because the work happens at gutter height on every elevation; a single run, such as one rotten length above a garage, can often be done from a tower for less. The installer strips the old boards, checks and treats the rafter ends behind, fits the new fascias, soffits and trims, and rehangs or renews the guttering. Most whole-house jobs are done in two to four days including the scaffold.

What fascias and soffits cost

These are the 2026 rates from our fascias and soffits cost guide, which also covers what scaffold adds and when capping makes sense:

JobTypical cost (2026)
Per metre, supplied & fitted (uPVC)£60 – £120
Capping over existing boards (per metre)£40 – £70
Semi-detached, full replacement£1,200 – £2,800
Detached, full replacement£2,000 – £4,500
Semi with new guttering included£1,800 – £3,600
Red flag: never cap over rotten timber. The uPVC skin hides the rot while it keeps spreading into the rafter feet, turning a fascia job into structural roof repairs. A reputable installer inspects the boards first and refuses to cap decayed timber; anyone happy to cap without looking is selling a cover-up, not a repair.

The ventilation bonus

Soffits are your loft's air intake, and old timber ones are often unvented or sealed shut by decades of paint. That traps moist household air in the roof space, where it condenses on the underside of the felt and drips back onto the insulation. New vented soffits restore the airflow and cure many persistent damp-loft problems as a side effect of the job. If your loft drips in winter, read our guide to condensation in the loft before blaming the roof covering.

Fascias & soffits FAQs

Fascia and soffit questions, answered

Full fascia and soffit replacement on a typical UK semi-detached house costs £1,200 to £2,800 in 2026 in uPVC, supplied and fitted, or £60 to £120 per metre. A detached house runs £2,000 to £4,500, and adding new guttering takes a semi to £1,800 to £3,600. Full breakdown in the fascias and soffits cost guide.
The fascia is the vertical board along the roof edge that carries the guttering; the soffit is the horizontal board underneath that closes the gap back to the wall. Fascias take the structural load of the gutters, while soffits keep weather and pests out of the roof space and, when vented, supply the airflow the loft needs.
Only over sound, dry timber. Capping fixes new uPVC over the existing boards at £40 to £70 per metre and is a legitimate budget option when the timber is healthy. Capping over rotten boards hides the rot while it spreads into the rafter feet, so a reputable installer inspects first and refuses to cap decayed timber.
20 to 30+ years. uPVC boards do not rot, never need painting and only need an occasional wipe-down. Installation quality matters more than the boards themselves: properly fixed, adequately ventilated boards routinely outlast the guttering hung from them.
Often, yes. Old timber soffits are frequently unvented or sealed shut by decades of paint, trapping moist air in the roof space where it condenses on the underside of the felt. New vented soffits restore that airflow and cure many persistent problems; see our loft condensation guide.
