Damp Proofing, Woodworm & Wet Rot Treatment in Bournemouth and Across Dorset

Woodworm is often identified by small round exit holes in timber, fine powdery dust (known as frass), crumbling edges on joists or floorboards, and weakened timber that feels soft when pressed. In many Bournemouth and Dorset homes, woodworm infestations are discovered during surveys when hidden structural timbers are inspected. If left untreated, woodworm can cause serious damage to floors, roof timbers and furniture. A professional survey will confirm the type of beetle and the best treatment for your property.

Both wet rot and dry rot are caused by excess moisture but they develop differently. Wet rot usually stays localised and makes timber feel spongy, with darkened patches and a musty smell. Dry rot, on the other hand, can spread rapidly through walls and masonry, producing grey or white fungal growths and deep cracks in timber. In Bournemouth and Dorset properties, older houses are particularly at risk. A survey is the most reliable way to confirm the type of rot and ensure the right treatment is applied.

Yes — a damp survey is the first step before any work begins. Without a proper inspection, it’s difficult to confirm whether issues are caused by rising damp, penetrating damp, condensation, or even hidden leaks. Our surveys across Bournemouth and Dorset involve moisture testing, visual inspection of timbers, and identification of underlying causes. This ensures the treatment plan is accurate, cost-effective, and provides long-term protection for your property.

The cost of damp proofing depends on the extent of the issue and the size of the property. For example, condensation control measures are generally less expensive than installing a new damp proof course or treating widespread timber decay. In Bournemouth and across Dorset, surveys provide a clear breakdown of the costs involved, along with tailored recommendations. Investing in damp proofing not only prevents structural damage but also protects your home’s long-term value.

Condensation is usually caused by poor ventilation combined with everyday activities such as cooking, drying clothes, or showering. Moisture builds up on cold surfaces, leading to mould growth and potential timber decay. Many homes in Bournemouth and Dorset, particularly older or poorly ventilated ones, suffer from recurring condensation. Solutions may include improving airflow with sub-floor ventilation systems, repairing damp proofing, or adding targeted treatments to prevent mould and protect indoor air quality.
