Damp Proofing in Tredegar

Groundwater travelling up through walls and floors. We install chemical damp proof courses and replaster with specialist materials for a permanent fix. Backed by a 20-year written guarantee.

Water ingress through walls, roofs, or around windows. We identify every entry point and apply targeted waterproofing repairs to stop it at the source.

Black mould and streaming windows signal poor ventilation. We treat existing mould, improve airflow, and apply anti-condensation coatings to keep homes healthy.

Tanking systems and cavity drain membranes to create genuinely dry, usable basement spaces — whether for a utility room, office, or extra living area.

Damp conditions allow woodworm and fungal decay to take hold. We treat and replace affected timbers and resolve the underlying damp cause to prevent recurrence.

Fungal decay can spread rapidly through a property. We contain it, treat with specialist fungicides, and replace any structurally compromised timber.

Corroded or missing wall ties cause cracking and structural movement. We survey and replace them using specialist stainless steel helical ties with minimal disruption.

Cracked or eroded mortar joints let water directly into the wall structure. We repoint using the correct lime or sand-cement mix to match the original construction.

Not sure what type of damp you have? Our thorough surveys include moisture readings and a full written report — essential for property purchases and housing association works.

Cold internal walls cause condensation, mould, and heat loss. We install the Wykamol Isotherm Tiwi system to transform cold walls into warm, dry, energy-efficient surfaces.
