Concrete / Finlock Gutter Replacement in New Eltham (33)

Concrete guttering, commonly known as Finlock gutters, was widely installed on UK homes from the 1950s to the 1970s. However, over time, many of these systems develop leaks, cracks, or water run-off issues.

What is concrete/Finlock guttering?

Concrete or Finlock guttering is a built-in gutter system formed as part of the roof edge, typically made from reinforced concrete.

Unlike modern external gutters, Finlock systems sit between the roof and the external wall.

Signs you might need Finlock gutter replacement

• Water running down external walls
• Persistent damp or mould near the roofline
• Cracks or spalling in the concrete
• Overflowing gutters during rainfall
• Internal damp caused by poor drainage
• Previous patch repairs that haven’t resolved issues

Why do Finlock gutters usually need replacing?

Over time, concrete guttering can crack, absorb water, and lose its ability to drain effectively.

Because the gutter is built into the structure, repairs are often short-term. Replacement is commonly chosen to permanently redirect rainwater away from the property.

How much does Finlock guttering replacement cost?

For concrete/Finlock gutter replacement, expect to pay between £1211 and £2905, with an average cost of £1883.

Concrete gutter replacement costs are normally influenced by:

• Length of roofline being replaced
• Property height and access requirements
• Removal method (cut-back or over-cladding)
• Replacement gutter type (uPVC or aluminium)
• Scaffolding needs
• Disposal of concrete waste

What replaces concrete/Finlock guttering?

Most Finlock gutter systems are replaced by:

• uPVC guttering: lower upfront cost, lightweight
• Aluminium guttering: longer lifespan, minimal maintenance

The new guttering is typically fixed to the fascia after the concrete section is removed or capped, allowing rainwater to drain externally, as with modern systems.

How is concrete/Finlock guttering replaced?

Finlock gutter replacement usually follows these steps:

1. Scaffolding is erected for safe access
2. The concrete gutter section is cut back or removed
3. Roof tiles are extended to the new roof edge
4. Fascia boards are installed
5. New external guttering and downpipes are fitted

This approach helps permanently resolve drainage problems.

How long does Finlock gutter replacement take?

• Small properties: 1–2 days
• Average homes: 2–3 days
• Larger or complex rooflines: 3–5 days

Timescales usually depend on access, weather, and roof structure.

How long does replacement guttering last?

• uPVC guttering: 20–30 years
• Aluminium guttering: 30–40 years

The longevity of your guttering depends on exposure, maintenance, and installation approach.

Maintenance after gutter replacement

Modern guttering generally requires less upkeep than Finlock systems. Aim to:

• Clear debris once or twice a year
• Check joints and brackets after storms
• Keep downpipes free-flowing
• Inspect roof edges periodically
