“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

Diagnosis first — because the wrong treatment fixes nothing
Rising damp, penetrating damp and condensation can look almost identical on a wall, yet they need completely different treatments. Getting that diagnosis wrong is the single most common reason damp “comes back” after money has already been spent.
Our surveys are diagnosis-led and genuinely independent. We use calibrated moisture meters and specialist testing to establish the true cause, then set it out in plain English — recommending only the work that is actually needed, never treatment for its own sake.
You receive a clear, written report you can act on with confidence. If remedial work is required, our own in-house team can carry it out under a 25-year insured guarantee — but the choice is always yours.
The surveys we carry out
Whatever the concern, our surveyors get to the true cause before anyone talks about treatment.
Damp surveys
A full diagnosis of rising, penetrating and condensation-related damp using moisture meters and, where needed, salt analysis — so the right treatment is specified first time.
Timber surveys
Inspection for woodworm, wet rot and dry rot, establishing the type, extent and cause of any decay affecting floors, joists and roof timbers.
Mould & ventilation surveys
Assessment of mould, humidity and air movement to identify why moisture is building up and what ventilation is needed to protect your home and health.
Pre-purchase & specialist reports
Independent specialist reporting for buyers, sellers and homeowners who need a clear, impartial view of a property’s damp and timber condition.
Real projects that started with a proper survey
