Door Hinge & Floor Spring Replacement
Commercial-grade floor spring and hinge replacement for frameless glass doors — hydraulic mechanism overhaul, concrete box excavation, drop seal integration, and emergency response for failed closers.
Warning Sign: Oil at the Base of Your Glass Door
If you see hydraulic oil pooling at the base of your glass door, the floor spring seal has blown. The door has lost its braking mechanism and is at immediate risk of slamming uncontrolled. Call us before it fails completely.
The Hidden Danger of a Failed Floor Spring
A frameless glass door weighing 40–80 kg depends entirely on its hydraulic closing mechanism — the floor spring — to close in a controlled, safe arc. When the hydraulic seal fails and fluid leaks, the door loses all resistance. A heavy glass door caught by wind or a strong push can slam shut with enough force to shatter on impact or cause severe crushing injuries. This is not a maintenance inconvenience — it is a liability and safety emergency. Building managers, F&B operators, and retail tenants face direct liability exposure from a failed closer.
JWE replaces hydraulic floor springs, overhead pivot closers, and commercial-grade hinges for all types of aluminium and frameless glass doors. Our scope covers everything from the mechanical replacement itself to concrete box excavation (when the old unit has rusted solid into the floor), drop seal integration, and frame alignment correction where door misalignment has accelerated hardware wear. Because we fabricate our own aluminium frames, we understand the full system — not just the hardware in isolation — and can correct underlying alignment problems that caused the failure in the first place.
Premium Hardware Upgrade
We install high-cycle commercial floor springs calibrated to the exact weight and size of your door — not generic builder-grade replacements. Properly rated hardware lasts significantly longer under daily commercial use.
Concrete Box Excavation
When a floor spring box has corroded solid into the concrete slab, we carefully excavate and cast a new stainless steel housing precisely flush with the finished floor level — wet works capability that most glaziers cannot offer.
Drop Seal & Frame Alignment
While the door is removed for floor spring replacement, we upgrade the bottom rail with an automatic drop seal for dust and draught exclusion, and correct any frame misalignment that contributed to premature hardware wear.
Emergency Response
Failed Closer = Safety Hazard
A frameless glass door that has lost hydraulic resistance is a danger to every person who passes through it. We prioritise failed floor spring calls and can mobilise same-day for contract clients.
Report a Failing Door
Tell us the door type (frameless glass, aluminium frame), the symptom (slamming, stiff, grinding), and the building address. We will arrange a site assessment promptly.

Frequently Asked Questions
What is the oil pooling at the base of my glass door?
The oil is hydraulic fluid leaking from the floor spring's internal seal. The floor spring uses pressurised hydraulic fluid to control the door's closing speed and prevent slamming. Once the seal blows, the fluid escapes and the door loses its braking mechanism entirely. It is dangerous to continue using the door. Call us immediately — this is a safety issue, not a minor maintenance item.
Can the floor spring be repaired, or does it need full replacement?
Hydraulic floor springs cannot be reliably field-repaired once the internal seal has failed. The unit must be replaced. Attempting to top up the hydraulic fluid without replacing the seal will only result in the same failure within weeks. We always replace failed floor springs with a correctly rated new unit — we never patch or re-fill an already failed mechanism.
How long does a floor spring replacement take?
A straightforward floor spring replacement on an existing accessible box typically takes 3–4 hours on site. If the old floor spring box has corroded and must be excavated from the concrete slab, the concrete works add 1 working day for curing before the new unit can be installed. We provide a precise scope in our quotation so you can plan access and operational disruption accordingly.
