Rising Damp in Llanishen
Expert rising damp treatment for properties in Llanishen, South Glamorgan. 20-year guarantee. Free surveys with no obligation.
Post-war housing in Llanishen frequently suffers from condensation and poor subfloor ventilation. Older village properties in the area require more traditional damp proofing approaches.
Rising Damp Treatment in Llanishen
Rising damp occurs when groundwater travels upward through the pores and capillaries of a masonry wall — a process known as capillary action. Left untreated, it causes plaster failure, salt deposits (tide marks), damaged skirting boards, and eventually structural deterioration. EverDry Damp diagnoses rising damp accurately using calibrated moisture meters and thermal imaging, then installs a chemical damp proof course that forms a permanent barrier within the masonry. All affected plaster is removed and replaced with a specialist salt-resistant render, giving you a lasting finish backed by a 20-year written guarantee.

Frequently Asked Questions — Rising Damp in Llanishen
How long does rising damp treatment take?
Most residential jobs take 1–2 days for injection and plaster removal. Re-plastering is usually completed within a further 1–2 days once the walls have dried slightly.
Will rising damp come back after treatment?
A properly installed chemical DPC creates a permanent barrier. All rising damp treatment work is backed by a 20-year written guarantee, covering both the DPC installation and the specialist replastering.
Do I need to decorate after treatment?
Yes — once the new plaster has fully dried (typically 4–6 weeks), you can paint or wallpaper as normal. We advise using a breathable emulsion for the first coat.
Is rising damp covered by home insurance?
Generally no — most policies treat rising damp as a maintenance issue. However, a professional survey report from us can be used to demonstrate the condition for property transactions.
