Specialists in On-Site Façade Water Testing
LFT Maintenance Ltd is a UKAS accredited testing laboratory No. 9245, providing specialist on-site façade water testing across the UK. We help main contractors, façade installers and building owners with hose, spray bar and cabinet testing on commercial and residential projects. Accreditation applies to the tests listed in our UKAS schedule.
Specialist testing. Clear results.
We work with main contractors, façade installers and building owners to check installed façades for water penetration and investigate reported leaks.
Our technicians use calibrated equipment and controlled test methods, with findings documented to support your project team’s next steps.
Send us your project specification, site location and preferred testing dates. We’ll confirm the proposed test method, access requirements and whether the testing falls within our UKAS accredited scope.
Roof & Façade Leak Investigation
Water entering a building can travel before it becomes visible, making the source difficult to locate.
LFT investigates leaks through roofs, windows, curtain walling and building façades, using targeted inspections and controlled water testing to help trace where water enters.
We document our findings to help your project team plan the next steps. Tell us where the leak appears, when it occurs and what repairs have already been attempted.
Safe access. Controlled testing.
Our IPAF and IRATA trained technicians bring practical experience of working at height to façade testing and maintenance projects.
We plan access and testing around the building, site conditions and agreed scope, coordinating with your site team before work begins.
From powered access to rope access, we can discuss suitable arrangements for reaching difficult areas of the façade.
