Mastic Work
Mastic Work Professional mastic renewal and repair by abseil across London. Restoring weatherproofing on tower blocks and commercial buildings.
Mastic seals around windows, joints, and cladding panels are critical to keeping a building watertight, and they have a finite lifespan. London weather, UV exposure, and building movement all degrade mastic over time, eventually causing it to shrink, crack, and pull away from the substrate. Once that happens, water finds its way into the building and the damage starts compounding.
We carry out mastic work by abseil on tower blocks, commercial buildings, and residential developments across London.
