UPVC Soffit and Fascia › Caerphilly › Guide
Most houses in Caerphilly with timber fascias and soffits can be changed over to UPVC. The terraces near the castle, the valley-side rows and the big post-war estates all have the same basic roofline, and the job follows the same steps. What changes from house to house is the condition of what lies behind the old boards.
What replacing timber with UPVC actually involves
The old boards are taken off along the eaves, which means the gutters come down first. We then look at the rafter ends, the wall plate and the underside of the roof covering at the edge. New UPVC fascias and soffits are fixed in their place, and the gutters are refitted or renewed. It is a full roofline job, not a quick cover-up. The result is a roofline that is firm, tidy and ready for the weather coming off the mountain.
Why timber boards fail on Caerphilly houses
Timber rots where water sits, behind the gutter and at the joints between lengths. On the mountain edge of the town, wind-driven rain pushes water into those joints, and the paint cracks and lets it in. A board that looks only flaky from the ground can be soft underneath, so a close look matters before anyone decides whether to repaint or replace.
- Water trapped behind leaking or blocked gutters
- Open joints between lengths of fascia or soffit
- Paint that has failed on the exposed side of the house
- Wet rafter ends where the board has been letting water in
What we check before the old boards are disturbed
On older homes we check what the existing soffit boards are made of before they are disturbed, and we handle them accordingly. We also look at rafter ends for rot, check the eaves are properly supported and see whether the roof covering overhangs the gutter correctly. If a rafter end is damaged, we tell you before going further, because new boards fixed to rotten timber will not hold.
Capping over or full replacement
Capping over means fitting UPVC over existing timber that is still sound. It can suit a board in good order, but it hides what is behind and does nothing for a rotten fascia. Where there is any doubt, or the soffits are solid and need ventilation, we recommend taking the old boards off and starting with a clean, firm roofline.
- Capping over suits sound timber only
- Full replacement lets us inspect the rafter ends
- Vented soffits need the old solid boards removed
Ventilation, gutters and finish
New soffits can be vented, or fitted with vent strips, so air moves through the roof space and helps the loft stay drier. Gutters are usually replaced at the same time, since they must come off anyway. UPVC is cleaned rather than painted, and comes in white, darker colours and wood-effect finishes. It is very low maintenance, not no maintenance. Some roofline work may need planning or Building Regulations checks — we advise before work starts.

Common Questions
Can I keep my timber boards and just paint them?
If the timber is sound, painting is possible, but on exposed Caerphilly houses repainting needs doing regularly. If boards have gone soft, painting only hides the problem. We can look at them and tell you honestly which route makes sense.
Will UPVC fit on a house in Bedwas or Machen?
Yes. UPVC boards are fitted to the rafter ends in the same way wherever the house stands. The villages around Caerphilly share the same style of roofline, and we adjust the board sizes and fixings to suit each house.
How long does a replacement take?
That depends on the size of the house and the condition of the rafter ends. A typical semi is a short job once the scaffold is up, but we explain the stages and any extra work before we start.
