Damp Surveys in Cardiff
Independent damp surveys across Cardiff, from the Victorian terraces of Roath and Cathays to Bay-side apartments and post-war homes in Llanishen. We diagnose the real cause, not sell you a remedy.
Independent, evidence-based surveys
A Cardiff damp survey should answer one question: what is actually causing the moisture? Cardiff's housing stock ranges from Edwardian terraces in Canton and Cathays to modern flats in Cardiff Bay, and each has its own predictable damp patterns.
Our independent damp survey Cardiff service inspects walls, floors, chimneys, sub-floor voids and rainwater goods using calibrated moisture meters and thermal imaging. You receive a clear written report with photographs and prioritised actions.
Because we don't sell damp-proofing, we have no reason to recommend chemical injection, tanking or any treatment you don't need. You get an unbiased Cardiff surveyor's view.
Common damp problems in Cardiff properties
Victorian terraces
Cathays, Roath and Canton terraces often have solid walls, original lime mortar and bridged DPCs from later patios.
Cardiff Bay flats
Coastal exposure and balcony detailing produce wind-driven rain ingress around windows and parapets.
Post-war semis
Llanishen, Rhiwbina and Llanederyn homes often suffer cavity wall tie failure and bridged cavities.
Failed pointing & render
South Wales weather is hard on mortar joints, driving rain finds the smallest defect.
Sub-floor ventilation
Blocked airbricks beneath suspended timber floors cause persistent ground-floor damp.
Misdiagnosed condensation
Many 'rising damp' problems in Cardiff are condensation needing ventilation, not injection.

Why independent surveys matter
We don't sell treatments, chemicals, or remedial work. That means our only job is to find the truth and explain it to you clearly.
We don't sell damp-proof courses, chemical injections or tanking. Recommendations are based purely on what your property needs.
Every finding in our damp survey Cardiff report is supported by moisture readings and photographs, so you can take it to any builder for fair quotes.
If your property doesn't need invasive treatment, we'll say so. Sometimes the fix is a £15 airbrick clearance, not a £4,000 injection system.

Surveys tailored to Cardiff
We've surveyed properties across Cardiff including Cathays, Roath, Canton, Pontcanna, Cardiff Bay, Penarth, Llanishen, Whitchurch, Rhiwbina and Llanederyn. Each area has its own quirks, from coastal exposure at the Bay to solid-wall terraces in the city centre.
If a Cardiff surveyor or damp-proofing firm has recommended extensive chemical treatment, a second opinion can save thousands. Many Cardiff damp problems are resolved with external repairs and ventilation.
Summer is the ideal time to book a Cardiff damp survey, dry weather lets us pinpoint render, pointing, roof and ground-level defects that are masked when walls are actively wet, so repairs can be done before autumn rain returns.
