What is an Independent Damp Survey?

Comprehensive Moisture Inspection Without Bias

An independent damp survey is a professional, impartial inspection of your property to identify the presence, source, and severity of moisture-related problems. Unlike surveys conducted by treatment companies, our independent damp survey London service has no financial incentive to recommend unnecessary work.

We use calibrated moisture meters, hygrometers, thermal imaging cameras, and specialist diagnostic equipment to accurately diagnose damp type — whether rising damp, penetrating damp, condensation, or timber decay. Our detailed reports include photographs, moisture readings, root cause analysis, and clear, prioritised recommendations.

Whether you're buying a property, selling, refinancing, or concerned about existing damp, an independent damp survey London provides the clarity and honesty you need to make informed decisions.

Moisture Meter Testing

Calibrated digital moisture meters measure moisture content in walls, floors, and ceilings — identifying exact moisture levels and patterns.

Professional thermal imaging camera equipment

Thermal Imaging

FLIR thermal cameras detect hidden moisture behind walls, under floors, and within ceilings — revealing damp invisible to the naked eye.

Inspection of roofing, guttering, downpipes, brickwork, pointing, and window frames — identifying water ingress points and defects.

Timber decay and rot probing inspection

Specialist probing of floor joists, skirting boards, window frames, and structural timbers — detecting wet rot, dry rot, and woodworm.

Ventilation and air quality assessment

Ventilation Assessment

Evaluation of air circulation in kitchens, bathrooms, loft spaces, and sub-floor voids — identifying poor ventilation as a damp driver.
