Damp Proofing FAQs
Do you cover Somerset, Wiltshire, and Gloucestershire?
Yes, we provide expert damp proofing throughout these counties and the wider South West.
How do I know if I have damp?
Common signs include mould, damp patches, peeling paint, or musty odours.
Is damp proofing permanent?
When properly installed, treatments can last decades.
Do you offer surveys?
Yes—we provide professional surveys and assessments across Bath, Bristol, Frome, Gloucester, Weston-super-Mare, Warminster, and surrounding towns.
Timber Treatment in Thornbury
Timber problems can remain hidden within floors, roofs and structural timbers until noticeable damage has developed. TPS inspects properties to establish the type and extent of the problem before recommending any necessary treatment.
Our timber services include woodworm inspection and treatment, deathwatch beetle investigation, common furniture beetle treatment, wet rot and dry rot investigation, assessment of affected structural timbers, and advice on moisture conditions contributing to timber decay.
Not every hole found in timber indicates an active infestation. A proper inspection helps determine whether activity is current, identify the affected beetle where possible and establish whether treatment or timber repairs are required.
Damp Surveys and Damp Proofing in Thornbury
Dampness can have several possible causes, including rising damp, penetrating damp, defective external finishes, high external ground levels, plumbing faults and condensation.
TPS carries out property inspections to identify the likely source of moisture before specifying remedial work. Where appropriate, our services can include damp-proof course installation, treatment of salt-contaminated wall finishes, penetrating-damp investigation, internal damp-proofing systems, and removal and replacement of affected plaster.
We do not assume that every damp patch requires a replacement damp-proof course. The proposed solution will be based on the condition of the property and the findings of the inspection.
Basement and Cellar Waterproofing in Thornbury
Basements, cellars and other below-ground rooms require a waterproofing system suited to the construction, condition and intended use of the space. TPS installs both tanking slurry and cavity-drain membrane systems where appropriate.
Tanking Slurry Systems
A cementitious tanking system creates a waterproof barrier across properly prepared walls and floors. Correct preparation and careful treatment of joints and vulnerable areas are essential to the completed system.
Cavity-Drain Membrane Systems
A cavity-drain membrane system manages water behind an internal membrane before directing it towards a suitable drainage point or sump-and-pump arrangement. The correct waterproofing method can only be determined after considering the individual property and the extent of water ingress.
Condensation and PIV Installation in Thornbury
Condensation occurs when moisture within the air reaches colder surfaces. Common signs include water on windows, mould growth, musty odours and recurring dampness around colder walls or corners.
TPS investigates the conditions within the property before recommending a ventilation solution. Where suitable, a Positive Input Ventilation system can introduce a continuous supply of filtered air to help reduce excessive humidity, condensation and mould.
PIV is not the correct solution for every damp problem. Water ingress, plumbing defects and building faults must be distinguished from moisture produced within the home.
A Survey-Led Approach
Our purpose is to identify the likely cause of the problem and recommend work appropriate to the property. Following an agreed survey or inspection, TPS can provide the relevant findings or report and a written quotation describing the proposed work. Any applicable guarantees or insurance-backed cover will be confirmed in writing before work proceeds.

Frequently Asked Questions
Do you carry out damp surveys in Thornbury?
Yes. TPS inspects properties in Thornbury to investigate suspected rising damp, penetrating damp, condensation and other moisture-related problems. The appropriate type of inspection will depend on the property and the reason for the enquiry.
Can you identify and treat woodworm?
TPS can inspect affected timber to determine whether signs of wood-boring insects appear active and, where possible, identify the beetle involved. Any recommended treatment will be based on the findings of the inspection.
Do you waterproof basements and cellars?
Yes. TPS installs tanking slurry and cavity-drain membrane systems. The appropriate system depends on the building, the level of water ingress and the intended use of the space.
Can PIV help with condensation and mould?
A correctly specified PIV system can help reduce condensation and mould caused by excessive internal humidity and insufficient ventilation. TPS will consider whether PIV is suitable before recommending installation.
