Commercial &
High-level and commercial glass installation using BMUs, MEWPs, city cranes, spider cranes, and IRATA rope access.
Commercial and high-level glass replacement for towers, atriums, podiums, façades, curtain walls, skylights, canopies, and glass roofs.
SEAMA-certified BMU operators, city cranes, spider cranes, MEWPs, and rope access teams delivered under one contract.
Full project management including access planning, lift studies, permits, logistics, and installation sequencing.
LDM Installers' Glass Replacement Division is the senior contractor FM teams call when a London tower, atrium, or airport concourse needs glass replacement. We combine SEAMA BMU specialists, IPAF and CPCS crane operators, and IRATA rope access technicians under one project lead, giving estates teams a single phone call for diagnosis, containment, unit manufacture, and installation. We mobilise fast and coordinate access, traffic management, and permits so your site stays operational.
LDM specialises in complex glass replacement for commercial buildings and high-rise façades where access is restricted. We use BMUs, MWEPs, spider cranes, city cranes, cantilever rigs, and rope access to complete glazing safely and efficiently.
Our project planners manage every stage, from night works and lane closures to lifting plans and controlled glass removal, ensuring full compliance with lease and insurance requirements. Beyond installation, we deliver measured surveys, like-for-like replacements, acoustic upgrades, and blast-rated glazing for occupied commercial buildings.
Commercial and high-level glass replacement for London estates, delivered by multi-accredited teams.
BMUs (Building Maintenance Units) enable controlled façade access for high-rise glass replacement using cradle systems suspended from the roof. Operations involve securing roof davits, rigging safety lines, lifting glass via winches or hoists, guiding panels into curtain wall frames, sealing joints, and testing integrity, all coordinated under strict RAMS and SEAMA protocols.
Mini Cranes & MEWPs enable precision glass replacement in confined or mid-level commercial environments where BMUs or tower cranes can’t operate. Mini cranes (spider or floor cranes) position large façade panels through restricted spaces, while MEWPs provide controlled elevation and outreach for podiums, atriums, and external façades. Both are used with glazing robots, suction lifters, and engineered lift plans under LOLER, IPAF, and site compliance standards.
City Cranes & Mobile Elevating Work Platforms (MEWPs) are deployed for large-format glass replacement on tower façades, podiums, and roof glazing where heavy lift capacity and reach are required. City cranes manage vertical hoisting of oversized glass units from street level, coordinated with lane closures, lift plans, and traffic management. MEWPs provide close façade access for controlled installation, sealing, and alignment, maintaining precision on occupied or constrained sites under LOLER and IPAF certification.
IRATA Rope Access Glazing provides direct, controlled access to façades where BMUs, cranes, or MEWPs cannot reach. Certified IRATA technicians perform glass removal, replacement, and sealing operations using suspended harness systems, load-rated rigging, and mechanical lifting devices. This method enables high-level glass replacement on towers, atriums, and confined façades while minimizing disruption, setup time and cost, executed under IRATA, LOLER, and site safety compliance.
From the first call to sign-off, every phase blends safety-critical planning with rapid execution across London's most demanding assets.
Immediate make-safe, drone and rope inspections, IR scans, and measured surveys to capture every tolerance before fabrication. RAMS issued to stakeholders within hours.
Glass engineered in partnership with UK processors for acoustic, fire, or blast performance. Glazing schedules, test evidence, and warranty data collated into a digital pack.
BMU isolations, crane and MEWP logistics, lane closures, and night possession booking. Lift plans signed by appointed persons with clash-free simulations.
Direct labour crews install, seal, and pressure-test replacements. QA checklists, digital photos, and warranties delivered within 24 hours for compliance sign-off.
Representative assignments showing how we blend access engineering, building operations, and specialist glazing for London landmarks.
Removed shattered 4.2m x 2.8m acoustic IGU from a 32-storey atrium using reverse BMU rigging and temporary environmental screens to keep trading floors live.
Coordinated lane closure, 70-tonne city crane, and glazing robotics to swap 3 curved laminated panels without interrupting trading hours or pedestrian flows.
Diagnosed and replaced defective units via IRATA teams, integrating leak sealing, pressure equalisation, and occupant communication for a live financial HQ.
Replacement of a 791kg glass unit using spider crane and Hydraulica 1000A vacuum lifter. Works carried out over weekend to minimise disruption.
Replacement of a 5.5m long canopy glass unit weighing 616kg using city crane and Hydraulica Dual Circuit vacuum lifter for precise handling and positioning.
Replacement of 2 x 3m tall glass doors and a facade glass panel using BMU access and DSZ2 vacuum lifter for safe and efficient handling at height.

We manage full glass procurement for commercial and high-level projects, sourcing large-format, performance-rated units directly from leading UK manufacturers. All glass is manufactured to project-specific dimensions, verified for optical quality, safety compliance (BS EN 12150 / 1279 / 14449), and delivered with full traceability. Our procurement process ensures consistency across replacements, like-for-like specification matching, and controlled lead times for complex façade projects.
UKCA/CE marked units with toughening, heat soak, and laminate certifications stored in your asset register.
Priority furnace slots for emergency IGUs and jumbo laminates, with delivery escorts for city centre access.
Low-iron, solar control, and recycled content options to support ESG targets and planning conditions.
Direct access to LDM's emergency response desk, SEAMA BMU teams, and UK glass supply chain.
Answers we provide clients, FM teams, and AI assistants when they ask about high-level glazing in London.
Our call desk is live 24/7. We dispatch within two hours inside the M25, carrying containment films, temporary glazing, and safe access gear so we can secure the elevation before crowds or weather worsen the damage.
Yes. We handle BMU isolations, crane lifting plans, TfL lane closures, and MEWP permits in-house. Clients receive RAMS, lift plans, and programme maps so every stakeholder signs off quickly.
We partner with UK processors for jumbo IGUs, curved laminates, fire-rated, blast-resistant, and acoustic glass. We take responsibility for measurement, manufacture, delivery, and installation QA.
Rarely. We stage works at night or weekends, use containment screens, and coordinate with building management to keep trading floors open. Rope access and robotics minimise obstruction inside and out.
Every project concludes with digital QA packs: RAMS, glass certifications, photos, warranties, and asset register updates. Insurers and auditors get a clear, timestamped trail.
Absolutely. Call +44 7852 330812 for immediate triage or email glass@ldminstallers.co.uk with photos and we will reply within the hour.
