Glass Door Repair, Hinges & Floor Spring Replacement in Singapore
Expert emergency diagnostics and structural restoration for residential, retail, and commercial glass installations. Specializing in hydraulic floor spring replacement, sagging frameless door alignment, heavy-duty hinge retrofit, patch lock replacements, and waterproof silicone sealant rectification.
Prevent Catastrophic Glass Shattering: Why Immediate Alignment & Hardware Servicing Is Critical
Heavy commercial and residential tempered glass doors (typically 10mm to 12mm thick) exert massive shear stress on floor springs and top pivot patch fittings—weighing between 45kg to 110kg per leaf. When a hydraulic floor spring leaks internal oil, the internal valve damper fails, causing the door to violently slam shut. In Singapore's humid tropical climate, worn-out hinge gaskets cause glass-to-metal contact, leading to instantaneous spontaneous tempered glass explosion.
At RH Glass, our BCA-trained glazier teams provide comprehensive diagnostic triage, precision re-centering, genuine OEM component replacement, and structural weather-seals. Rather than replacing entire glass door panels, our specialized mechanical retrofits restore seamless operation at a fraction of full replacement cost.
