Damp Proofing

We provide a full range of damp proofing services, including rising damp treatment, penetrating damp solutions, condensation control, basement and cellar waterproofing, external waterproofing, cavity wall damp solutions, damp surveys and assessments, and mould removal and prevention. Each service is tailored to the property’s specific construction type and moisture issue, with the aim of delivering long-term protection and a healthier internal environment.

Rising damp is the upward movement of ground moisture into the lower parts of a wall, usually through capillary action within porous masonry. Treatment typically involves installing an effective damp-proof course (DPC) to act as a barrier, preventing further moisture from rising. Where required, we also treat affected internal areas to address salts and staining that can remain after prolonged moisture exposure, helping restore the wall to a clean and stable condition.

Penetrating damp occurs when water enters through external walls due to defects such as cracked masonry, degraded pointing, or poor weatherproofing. The solution is to address the root cause, which can include repairs to brickwork or stonework, repointing, and the application of suitable waterproofing treatments. By stopping the entry point externally, you prevent ongoing internal damage and protect the building fabric.

Condensation is often linked to poor ventilation and high humidity, particularly in kitchens, bathrooms, and colder rooms. Our approach focuses on reducing moisture levels by improving airflow and addressing contributing factors such as insulation performance. Where mould is present, we carry out safe removal and then implement preventative measures so the conditions that caused the mould are properly managed going forward.

For below-ground spaces, we use waterproofing systems designed to resist moisture from surrounding ground and soil. This can include tanking systems and specialist membranes that create a watertight barrier. Waterproofing can protect storage areas, prevent damp spread into upper levels, and enable basements or cellars to be converted into practical, usable living space where appropriate.

A damp survey provides a structured diagnosis of the moisture issue using suitable inspection methods and diagnostic tools. The objective is to identify whether the problem is rising damp, penetrating damp, condensation, bridging damp, or cavity-related moisture, rather than relying on guesswork. Once the cause is confirmed, we provide tailored recommendations so you can take targeted, cost-effective steps to resolve the problem and prevent recurrence.
