We remove concrete gutters and rebuild the roof edge with a proper fascia, ventilated soffit and modern guttering — or, where it genuinely suits the house, talk you through relining instead.
Common Finlock problems we help with in Blandford
- Leaking concrete gutters dripping or staining the walls below
- Damp patches and mould along upstairs ceilings at the wall line
- Old liners that have split, lifted or been patched repeatedly
- Cracked or spalling concrete with rusting reinforcement showing
- Water overshooting outlets in heavy downpours
- Cold corners in bedrooms where the concrete bridges the wall

Why damp appears at the top of the wall
Two things often happen together. Water gets into the wall through cracked joints or a failed lining, and the solid concrete also acts as a cold bridge across the wall, so the inside surface stays cold and condensation forms. Fixing only one of those can leave the mould coming back.

- 3Water can enter through joints or defects in the concrete
- 4Thermal bridge — the concrete chills the upper internal wall
- 5Cold band forms on the internal wall
- 6Condensation and mould can follow
Repair or replace: relining vs full removal
When relining can make sense
- The concrete is structurally sound with no spalling
- Leaking is the only issue — no cold-bridge mould inside
- You're looking for a lower-cost, shorter-term fix
When removal is usually the better answer
- A previous liner has already failed
- Concrete is cracked, spalling or showing rusting steel
- Mould keeps returning on upstairs ceilings
- You want a conventional, easily maintained roof edge
Repair
Seals a joint and buys some time, but the cold bridge and the damp are still there underneath.
Line
Stops water getting in for less money, but every liner has a service life and will need doing again.
Remove & replace
Ventilation and redecoration can ease the symptoms, but they won't remove the thermal bridge or fix water getting in. What's right depends on the condition of the Finlock system and how it's built.
Finlock work around Blandford
Much of Blandford town centre was rebuilt in brick after the 1731 fire, so Finlock is mainly a feature of the 20th-century housing around it and in nearby villages such as Pimperne, Charlton Marshall and Blandford St Mary. Those homes are often semi-detached with neighbours on the same gutter line, so we plan how the join is finished at the party wall before work starts.
How removal and rebuilding works
We set up safe access, cut and lift the concrete in controlled sections, then rebuild the eaves with insulation where possible, new fascia and soffit, eaves ventilation and new guttering and downpipes. The bottom courses of the roof are made good so the finished edge looks like it was always there.
Existing Finlock
The concrete trough built into the wall head, with joints starting to open up.
Removal & rebuild
Blocks cut out, eaves rebuilt in timber, and the wall head insulated properly.
New roofline
New fascia, soffit and guttering, falling correctly to the outlets.
