Worried About Hidden Leak in Your London Property?
At Prime Building Care, we specialise in professional leak detection surveys that get to the source — fast. Whether you’re facing damp patches, unexplained mould, or rising water bills, we help you take action before it becomes a bigger (and costlier) problem.
✅ You’ve spotted staining, bubbling paint, or mould patches — and suspect a leak inside the wall or ceiling.
✅ A persistent musty smell or damp feeling has you worried — but you don’t know where it’s coming from.
✅ Plumbers or contractors gave conflicting opinions — and you want clear answers from a qualified surveyor.
✅ You’re buying a property with visible water damage and need to know the cause before you commit.
✅ You need a documented report for your repair contractor, landlord, or insurance provider.
The Hidden Cost of Persistent Leak — And Why Prime Building Care Does It Differently
At Prime Building Care, we’ve seen leaks that went unnoticed for months — sometimes years — until they caused serious structural damage. Damp insulation. Swollen floorboards. Hidden black mould. Rotten timbers. And all because no one found the true source early enough.
Too often, we’re called in after the damage is done — when plumbers guessed, contractors patched, and the root cause was never fully diagnosed.
That’s why we take a different approach.
Our qualified surveyors carry out detailed leak detection surveys using thermal imaging, moisture mapping, Borescope Camera, and non-invasive inspection tools to pinpoint the origin — whether it’s a pipe leak behind plasterboard, a failed flashing, or long-term water ingress in cavity walls.
We don’t just spot symptoms. We find the source, assess the risk, and give you a clear, written plan of action — fast.

Leak Detection FAQs
Everything You Need to Know Before You Book
-
A Specialist Leak Detection Survey is a diagnostic inspection carried out by a qualified surveyor to identify the source of water ingress, hidden plumbing leaks, roof penetration, or moisture tracking issues. We use thermal imaging, moisture mapping, and proven building pathology to locate the true cause — not just the symptoms.
-
Book a Leak Detection Survey if you suspect a specific source of water — like a roof leak, plumbing failure, balcony ingress, or leaking pipework — but aren’t sure where it’s coming from. It’s ideal when there’s visible damage (wet patches, stains, ceiling bubbles) but no obvious cause.
-
Every survey includes a full on-site inspection by a qualified building surveyor, thermal imaging scans (where needed), moisture meter readings, and diagnostic tests. You’ll receive a clear report with annotated photos, root cause analysis, and next-step recommendations.

We use thermal imaging whenever it helps isolate or confirm the source of moisture. It’s included at no extra charge if appropriate for your property — especially useful for ceiling leaks, roof failures, and wall tracking.
