Glass Door Repair Singapore: Floor Springs, Hinges and Common Problems
Glass Door Repair in Singapore: Diagnose and Fix the Real Problem
Glass doors are used constantly — hundreds of times a day in a busy office or shop. It is no surprise that hardware wears out. What surprises most owners is how often a door is replaced when a simple, inexpensive repair would have solved the problem completely.
In our experience, roughly 8 out of 10 glass door issues are hardware problems, not glass problems. This guide shows you how to identify them and what repair involves.
How a Frameless Glass Door Works
- Glass panel — 10–12 mm tempered glass.
- Floor spring — hydraulic unit set into the floor that carries the door weight and controls the swing.
- Top pivot — keeps the door vertically aligned.
- Patch fittings — stainless steel clamps connecting glass to hardware.
- Lock and handle — patch lock, floor lock or deadbolt, plus pull handles.
When any one of these wears, the door misbehaves. Identifying which component is at fault is the whole game.
Diagnosing Common Problems
| Symptom | Most Likely Cause | Repair |
|---|---|---|
| Door drags on the floor | Floor spring dropped; glass warped; pivot loose | Re-level spring box, adjust or replace pivot |
| Door slams shut | Floor spring speed valve worn or misadjusted | Adjust valves or replace floor spring |
| Door won't latch | Strike plate misaligned; latch tension lost | Realign strike; replace lock |
| Door won't stay open | Hold-open function failed | Replace or re-set floor spring |
| Door wobbles | Loose patch fittings or worn top pivot | Re-torque fittings; replace pivot |
| Squeaking noise | Dry pivot or binding gasket | Lubricate; adjust alignment |
| Water pooling under door | Worn silicone or missing drop seal | Re-silicone; fit drop seal |
| Rust marks on glass | Low-grade fittings in humid environment | Replace with SS 316 |
| Door hangs at an angle | Spring box tilted or slab settlement | Re-level and re-grout |
| Glass chipped at edge | Impact damage — structural risk | Replace panel immediately |
Floor Springs: The Component That Matters Most
The floor spring does three jobs: it carries the weight of the door, controls the closing speed, and provides the hold-open function. It is the hardest working part of any glass door.
Signs a Floor Spring Needs Replacing
- Hydraulic fluid leaking around the cover plate.
- Door slams no matter how the valves are adjusted.
- Door no longer self-closes.
- Hold-open no longer works.
- Grinding or scraping sound during operation.
- Visible corrosion on the cover plate.
- Door drifts or swings unevenly.
Floor Spring Replacement Process
- Remove the door panel safely using suction lifters.
- Open the floor cover plate and inspect the existing unit.
- Cut out the concrete core if a different size unit is required.
- Set the new spring box level in both directions — this is critical.
- Grout the box in and allow it to cure.
- Re-hang the door and connect the bottom pivot.
- Adjust closing speed and latching speed valves.
- Test operation multiple times and clean up.
Setting the floor spring level is the single most important step. A box that is off-level by even 2 mm will cause the door to drift, drag and wear out prematurely — no matter how good the hardware is.
Floor Spring Brands
| Brand | Origin | Notes |
|---|---|---|
| Dorma | Germany | Market leader; excellent reliability and parts availability |
| GEZE | Germany | Strong for heavy doors; excellent engineering |
| Häfele | Germany | Good value; widely stocked in Singapore |
| Unbranded | Various | Cheaper but typically fails within 1–3 years |
Patch Fittings and Hinges
Patch fittings clamp the glass and connect it to the hardware. They are subject to constant vibration, which gradually loosens the screws holding the glass.
- Check annually — re-torque all patch fitting screws.
- Inspect gaskets — hardened gaskets allow glass to move and chip.
- Grade matters — SS 304 for indoor, SS 316 for coastal and humid locations.
- Never over-tighten — over-torquing cracks the glass at the bolt hole.
Locks and Handles
| Type | Description | Best For |
|---|---|---|
| Patch lock | Mounted on the glass edge | Single doors, neat look |
| Floor lock | Bolts into the floor | Double doors |
| Deadbolt | Higher security, keyed both sides | External entrances |
| Pull handle | Back-to-back or single-sided | All glass doors |
| Digital lock | Keypad, card or biometric | Offices, clinics |

Repair or Replace?
| Situation | Recommendation |
|---|---|
| Door drags or misaligns | Repair — usually a spring or pivot issue |
| Floor spring leaking | Repair — replace the spring |
| Worn hinges or fittings | Repair — replace fittings |
| Loose or broken lock | Repair — replace the lock |
| Glass cracked or chipped | Replace the glass panel |
| Glass permanently cloudy or scratched | Replace the panel |
| Repeated failures after multiple repairs | Replace the door system |
Preventive Maintenance Schedule
| Frequency | Task |
|---|---|
| Monthly | Wipe hardware; check for looseness; listen for new noises |
| Quarterly | Re-torque patch fittings; check silicone; inspect floor spring cover |
| Every 6 months | Adjust closing speed; lubricate pivot; check gaskets |
| Annually | Full service; check glass edges for chips; replace worn seals |
For high-traffic commercial doors, halve these intervals. A door used 500 times a day wears out four times faster than one used 100 times a day.
When to Call a Professional
Always call a specialist for:
- Any floor spring work — incorrect installation damages the door and floor.
- Any glass handling — a 12 mm panel can weigh 60 kg or more.
- Any drilling or cutting of glass — tempered glass shatters instantly if drilled incorrectly.
- Any high-level or facade door work.
- Any commercial door that must be returned to service quickly.
