Pre-Purchase Damp & Timber Survey in London
An independent, PCAQT-certified damp and timber survey carried out before you exchange — so you know exactly what you’re buying, what it will cost to fix, and what you can negotiate on.
Why Buyers in London Book a Pre-Purchase Damp Survey
Your surveyor flagged damp
A general building survey noted damp but couldn’t identify the cause or cost. You need a specialist to tell you what it actually is.
Your solicitor wants a specialist report
The vendor’s solicitor has been asked for more detail — or your own solicitor has recommended independent investigation before exchange.
You spotted something yourself
Tide marks, musty smell, staining on plaster, or visible mould. You want to understand it before committing.
You want a negotiation tool
A written report with costings gives you evidence to renegotiate the purchase price or request the vendor carries out works before completion.
What Your Pre-Purchase Damp & Timber Survey Includes
Every survey is tailored to the property and your instructions. Below is what a standard pre-purchase inspection covers — carried out by a PCAQT-certified specialist, not a sales representative.
Rising & Penetrating Damp
Full inspection for evidence of rising damp from ground level and penetrating damp from the exterior envelope — walls, chimneys, window surrounds.
Timber: Rot & Beetle Infestation
Inspection of accessible wooden floors, joists, and structural timbers for wet rot, dry rot, and wood-boring beetle (woodworm) activity.
Roof Coverings & Rainwater Goods
Visual inspection of the roof, gutters, downpipes, and fascias for defects that could allow water ingress — a common cause of damp in London period properties.
Condensation & Ventilation
Assessment of condensation risk throughout the property, existing ventilation provision, and the adequacy of extract fans in kitchens and bathrooms.
General Building Condition
Broader assessment of building condition as it relates to moisture risk — including ground levels, external drainage, and subfloor ventilation where accessible.
