Leak Detection, Testing & Repair
Water getting into the building? We survey, carry out controlled water testing to find exactly where it's coming in, fix it and re-test to confirm the area is sealed.

Maintenance and repair of curtain walling and aluminium façades on high-rise, new-build, office and industrial buildings — leak detection, water testing, glazing, repairs and fire doors. Surveys are free, with no upfront payment and no obligation to proceed.






Facade Maintenance Ltd maintains and repairs aluminium window, door and façade systems across London — built on years of hands-on experience in window and door manufacturing, large-scale development façades and after-sales coordination.
We specialise in high-rise, new-build residential and commercial, office and industrial buildings — and if you have a double-glazed aluminium façade, we'll look after it. We work alongside landlords, leaseholders, property managers, developers, façade contractors and main contractors, delivering honest work at fair, transparent prices.
