Leak investigation & water testing
Façade leak investigation & water testing in London
Water getting into a building is rarely where it shows. We trace façade and curtain-wall leaks back to the real entry point with controlled water testing to CWCT guidelines, repair at source, then re-test to prove the detail is watertight — on occupied buildings, at height.
What we cover
Tracing water ingress through the build-up to the true entry point
Curtain wall, windows, cladding, roofs and balcony interfaces
Gaskets, seals, flashings and membranes repaired at source
