Damp Proofing Services in East Lancashire

Damp has more than one cause, and the wrong fix wastes money. We survey your property first, find out what's really going on, and only quote for the work that's needed. We cover Rishton, Accrington, Great Harwood, Blackburn and Darwen.

Rising & Penetrating Damp

Moisture rising from the ground, or water getting in through the walls. We install damp-proof courses, tanking and repairs that treat the cause, not just the stain.

Our specialisms

We specialise in the treatment of:

Our solutions include the installation of high-quality damp-proof courses (DPCs), tanking and ventilation systems, all tailored to suit the unique needs of each property.

Ventilation systems

To complement our damp and mould treatments, we also install a full range of domestic ventilation systems, including:

Positive Input Ventilation (PIV) units (heated only, to avoid cold air issues)
Bathroom and kitchen extractor fans
Passive vents and condensation control units

Ventilation is a key part of preventing future moisture build-up, and we only use reliable, UK-manufactured systems backed by long-term warranties and, where applicable, insurance-backed guarantees.

Our heated PIV systems are especially popular in social housing and tenanted properties due to their effectiveness and added security features. They're ideal for keeping homes free from damp and mould while maintaining a safe, warm and healthy indoor environment.
