Glass restoration in Singapore is the process of returning scratched, stained, etched, or hazy glass to original clarity without replacing the panel. Using cerium oxide polishing, diamond-abrasive resurfacing, and controlled chemical treatments, Lion City Glass restores most glass damage at roughly 30% of replacement cost, with no disruption to frames, waterproofing, or sealants. This guide walks you through identifying your glass problem, choosing the right service, and understanding what to expect.
Which Glass Restoration Service Do You Need?
Glass damage in Singapore falls into five main categories, each requiring a different restoration technique. Start by identifying what’s wrong with your glass, then match it to the right service.
- Scratches, swirl marks, handling marks, wiper-blade scores → Glass Polishing & Scratch Removal. Cerium oxide polishing removes surface damage without distortion.
- White haze, chalky spots, calcium buildup, rain-runoff streaks → Hardwater & Mineral Stain Removal. Controlled chemical treatment dissolves calcium/magnesium deposits.
- Frosted patches, cloudy texture, chemical discolouration → Acid Etch & Chemical Stain Removal. Diamond-abrasive resurfacing levels the etched glass surface.
- Dirty, stained, or weather-damaged building facades → Facade Glass Cleaning & Restoration. High-access rope/EWP work combined with chemical and mechanical restoration.
- Hazy, algae-covered, or yellowed skylights → Skylight Glass Cleaning & Restoration. Specialist access and treatment for horizontal/angled glass installations.
For any of these, consider adding nano hydrophobic glass coating afterwards — it creates a water-repellent barrier that slows future mineral buildup and makes routine cleaning significantly easier.
How to Tell If Your Glass Is Restorable
Most common glass damage in Singapore is restorable without replacement, but there are limits. Here’s how to quickly assess whether professional restoration is the right call for your situation.
Run your fingernail across the damage
If your nail catches on a scratch, the scratch is deep enough to matter but usually still within the polishable range (0.1–0.3mm depth). If your nail doesn’t catch, it’s a surface hazing or micro-scratch problem — almost always restorable. If the scratch feels like a gouge deeper than a credit-card edge, it may be beyond polishing.
Check if the damage is on the outside or inside
Wipe the affected area firmly with a damp microfibre cloth. If the marks disappear temporarily when wet, you’re looking at a cleanable surface deposit (soap scum, loose mineral residue, dirt). If they stay visible regardless of wetness, you have true surface damage — scratching, etching, or bonded hardwater — and professional restoration is required.
Look at the glass from multiple angles
Direct sunlight reveals most glass damage that’s invisible under indoor lighting. Wet your finger, rub the affected area, then look from a 30-degree angle in strong daylight. If the damage pattern remains, a professional can almost certainly restore it. Take photos at this angle and WhatsApp them to us — we can price the job from the photos alone.
Restoration vs Replacement: Which Is Right for You?
Restoration wins on cost, speed, and disruption for almost all shallow-to-medium glass damage. Replacement is only the right call when the damage is structural (cracks, chips through the full glass thickness) or when the glass itself has failed (delaminated laminated glass, broken tempered panels). For scratches, haze, stains, and acid etching, restoration delivers 90%+ clarity recovery at roughly 30% of replacement cost.

What to Expect During a Glass Restoration Job
A typical Lion City Glass restoration follows a predictable six-step process from initial assessment to final quality check. Understanding the flow helps you plan around the work and know what a professional restoration should look like.
- Free assessment. We visit the site (or you WhatsApp photos) and inspect the damage under daylight. We identify the damage type — scratch, hardwater, acid etch, biological, or compound — and estimate effort.
- Fixed-price quote. You receive a firm SGD price before any work starts. See our pricing page for typical ranges.
- Preparation. The work area is protected (floor covering, neighbouring glass, fittings). For wet processes, water capture and drainage are arranged.
- Restoration work. The specific technique depends on the damage: cerium oxide polishing for scratches, chemical treatment for mineral deposits, diamond-abrasive resurfacing for acid etch, or specialist access work for facades and skylights.
- Quality check. Optical inspection against daylight to confirm clarity recovery. Any residual issues are corrected on the spot.
- Optional nano coating. If agreed in advance, hydrophobic coating is applied to the restored glass for long-term protection.
How Long Does Glass Restoration Take in Singapore?
Most residential work is completed in a single visit. A typical scratched shower screen takes 45–90 minutes including setup and cleanup. Hardwater stain removal on a single shower enclosure runs 1–2 hours. Commercial facade and skylight work is scoped by panel count and access method — a typical multi-floor office facade restoration might run 2–5 days on site.
Preventing Future Glass Damage
Once your glass is restored, a few simple habits keep it looking new for years longer. Singapore’s tropical climate — high humidity, heavy rain, and strong UV — is unusually harsh on glass, so prevention matters more here than in drier climates.
- Wipe shower screens after each use. A 10-second squeegee stops 95% of hardwater mineral buildup. The deposits form during water evaporation, not water contact.
- Apply nano hydrophobic coating. A professional coating lasts 12–36 months depending on exposure and dramatically reduces future restoration frequency.
- Use pH-neutral cleaners only. Acidic bathroom cleaners (common in Singapore retail) cause acid etch damage over time. Stick to neutral glass cleaners or simple water with microfibre.
- Schedule regular professional cleaning. Facade glass should get professional treatment every 1–2 years; skylights every 6–12 months in Singapore’s climate. Catching minor staining early prevents permanent damage.
- Protect glass during renovations. Cement, tile grout, acid-based tile cleaners, and paint overspray are the most common causes of post-renovation glass damage. Cover glass surfaces completely before any construction work.
Frequently Asked Questions About Glass Restoration
What is glass restoration?
Glass restoration is the professional process of returning damaged glass to near-original clarity without replacing the panel. It uses cerium oxide compounds, diamond abrasives, chemical treatments, and mechanical polishing to remove scratches, hazing, mineral deposits, and acid etching from the glass surface.
What types of glass can be restored?
Lion City Glass restores float glass, tempered glass, laminated glass, polycarbonate, and acrylic. Tempered glass requires extra care to preserve the tempered surface layer — we train specifically for this. Coated glass (low-E, reflective, mirrored) requires case-by-case assessment because aggressive polishing can compromise the coating.
How much clarity comes back after restoration?
Most shallow-to-medium damage recovers 90–100% of original clarity. Deeper damage (deep scratches, severe acid etching, thick mineral scaling) may recover 70–85% — visually clear but with potentially subtle optical variation under specific lighting angles. We always show you the expected result before quoting.
Will restoration distort the glass?
No — when done by trained professionals using optical testing throughout the process. Distortion only occurs when glass is over-polished or polished unevenly. Our multi-stage technique with optical checks prevents this, which is why tempered glass and facade glass can be polished safely without compromising structural integrity.
Do you work with both residential and commercial clients?
Yes. Lion City Glass serves HDB flats, condominiums, landed homes, MCSTs, commercial towers, hotels, shopping malls, F&B outlets, and retail shopfronts across Singapore. Our pricing and scheduling scale from single-panel residential jobs to multi-floor commercial facade contracts.
