Pinpointing & Preventing Water Intrusion for Long-Term Protection

Water ingress is one of the most damaging issues a building can face, leading to damp, mold growth, material decay, and costly structural repairs. Identifying the source of leaks can be challenging, as water can travel through facades, roofs, and joints before appearing internally. A thorough leak detection survey is essential to locate entry points and prevent long-term damage.

At Peak Access Abseilers London, we specialize in detailed water ingress surveys, using rope access techniques, thermal imaging, and non-invasive leak detection methods to assess hard-to-reach areas quickly and efficiently. Whether it’s a roof leak, failed sealant, or facade water penetration, our expert analysis provides actionable solutions to keep your building dry and structurally sound.
