Frequently Asked Questions

What are the main signs of rising damp?

Typical indicators include damp or flaking plaster, tide marks on walls, damaged skirting boards and a musty smell. In coastal areas like Weston-super-Mare and Clevedon, moisture levels can make symptoms more noticeable. A full survey will identify the source and confirm whether rising damp is present.

What guarantees do you provide on damp and timber treatments?

We provide fully underwritten guarantees on all timber and damp treatments, typically ranging from 10 to 30 years depending on the ground level and the type of work carried out. This means your guarantee is protected independently. All treatments are installed to BioKil Crown standards and include full documentation for your records.

Do you cover areas outside Weston-super-Mare?

Yes. We cover Burnham-on-Sea, Highbridge, Clevedon, Portishead, Cheddar, Bridgwater, Wedmore, Wrington and the wider North Somerset area.

What causes rising damp in UK homes?

Rising damp occurs when moisture travels up through the masonry due to a failed damp proof course or missing barrier. Older Victorian and coastal properties in e.g. BS23 are particularly prone due to age, ground conditions and salt levels.

What should I prepare before damp or timber treatment work begins?

We need clear access to the areas being treated. This includes having pipework capped off or temporarily moved, radiators removed, and carpets rolled back where possible. It is also helpful if skirting boards are taken off in advance. Please ensure the space is clear of furniture, tables and personal belongings so we can work safely and efficiently. If any preparation cannot be done beforehand, let us know and we will advise on the best approach.

How is rising damp treated?

The most effective method is DPC injection using professional-grade materials and a membrane sheet. We remove damaged plaster, inject a chemical damp proof course, apply membrane, apply render and specialist breathable plasters. All treatments follow BioKil Crown system requirements for long-term effectiveness.

Can condensation and mould be fixed without major work?

Often, yes. Improved ventilation, moisture control and minor remedial works can resolve the problem. If mould is linked to an underlying damp issue, we provide a full treatment plan.

How long does damp proofing work last?

Professional DPC systems offer long-lasting protection when installed correctly. BioKil Crown systems are designed for durability, and we use approved products throughout to ensure reliable results.

Is woodworm dangerous to the structure of a property?

If untreated, woodworm can weaken floorboards, joists and roof timbers. Early treatment prevents structural issues. We carry out full inspections and apply the correct timber treatment based on the infestation type.

How much does damp proofing cost?

Costs depend on the extent of the damp, the size of the affected area and the required treatment. We provide transparent quotes after carrying out a, in-depth survey.

Will you need to remove plaster during treatment?

If rising damp is confirmed, damaged plaster is normally removed to allow proper installation of the new damp proof course and breathable plaster systems.
