Singapore’s tropical climate — constant humidity, acid rain, and high-rise wind exposure — creates unique challenges for building facade glass maintenance. Over time, glass facades accumulate mineral deposits, biological growth, atmospheric pollutants, and chemical staining that standard cleaning cannot address. Lion City Glass provides specialist facade glass cleaning and restoration services for commercial and residential high-rises across Singapore.
Why Facade Glass Restoration Is Different From Cleaning
Regular facade window cleaning removes surface dirt, dust, and grime. Facade glass restoration goes further — addressing the permanent staining, mineral etching, hardwater deposits, and surface damage that regular cleaning cannot remove. Our restoration service combines chemical treatment with precision polishing to return facade glass to its original clarity and transparency.
Common Facade Glass Problems We Solve
- Hardwater mineral streaks — White vertical streaks from rain runoff carrying dissolved minerals
- Biological staining — Green algae, mould, or lichen growth on glass
- Cement and construction residue — White haze left after renovation or waterproofing work
- Atmospheric pollution staining — Oily, grey deposits from urban air pollution
- Acid rain etching — Surface damage from Singapore’s acidic rainfall in highly urbanised areas
- Sealant and silicone residue — Stubborn marks from glazing or joint sealants
Our Facade Glass Restoration Process
Facade glass restoration requires working at height with proper safety equipment. All our facade restoration technicians are trained in rope access and/or elevated work platform (EWP) safety, and our work is carried out in compliance with Singapore’s Workplace Safety and Health (WSH) standards.
- Facade inspection — Assessment of staining type, severity, and coverage area
- Test patch — Small area test to verify treatment effectiveness before full application
- Chemical treatment — Targeted mineral acid or alkaline treatment based on stain type
- Mechanical polishing — Buffing to restore clarity and remove residual surface damage
- Rinse and neutralise — Thorough cleaning to remove all treatment residue
- Optional nano coating — Hydrophobic glass coating application for long-term protection
MCST Facade Glass Maintenance Programmes
For condominium Management Corporation Strata Titles (MCSTs) and commercial building management, Lion City Glass offers scheduled facade glass maintenance programmes. Regular professional maintenance prevents staining from becoming permanent, reduces long-term restoration costs, and maintains the building’s visual appeal and property value.
Our MCST programme includes:
- Annual or bi-annual facade glass inspection and treatment
- Priority scheduling for urgent stain removal
- Consistent pricing and service reporting for management records
- Discounted rates for contracted buildings
Post-Construction Facade Glass Cleaning
New and renovated buildings often have facade glass contaminated by cement splatter, silicone residue, paint overspray, and construction dust bonded to the glass surface. Our post-construction facade cleaning service efficiently removes all construction-related contamination before building handover or occupation.
Facade Power Washing Services Singapore
For heavily soiled facades — dust accumulation, biological film, pollution residue, bird droppings, or post-construction grime — we offer professional facade power washing as a maintenance service alongside our specialist restoration work. Power washing is the right tool when the facade just needs a deep clean rather than mechanical restoration; it’s faster, cheaper, and covers more square metres per visit than the polishing-based restoration process.
When to choose power washing vs glass restoration
- Facade power washing is right when: the facade is dirty but the glass itself is undamaged — just years of dust, biological film, pollution, and rainwater streaks. Power washing removes the surface contamination and returns the building to a clean presentation.
- Facade glass restoration is right when: the glass has actual damage — hardwater mineral deposits, acid-etch staining, biological bonding that has penetrated the surface, or scratches. These require mechanical polishing and chemical treatment, which power washing alone cannot fix.
- Water-fed pole cleaning is right when: the building is low-rise (up to 3.5 storeys) and the facade just needs a streak-free rinse — see our water-fed pole window cleaning service for landed homes and small commercial buildings.
If you’re not sure which one your building needs, share a few photos via WhatsApp and we’ll assess it for you — most buildings actually need a combination (power wash the majority of the facade, then spot-restore the few panels with deeper damage).
Our facade power washing approach
- Rope access and elevated work platform (EWP) trained — WSH-compliant for high-rise work up to any building height in Singapore.
- Low-pressure pure-water method for glass — even on a power wash job, the glass itself is cleaned using low-pressure deionised water to avoid risk of seal damage or micro-cracks.
- Higher-pressure treatment for cladding and frames — aluminium cladding, stone infills, and frames can handle higher pressure and benefit from it.
- Biodegradable detergent only where needed — for organic contamination like moss and algae, we use a mild biodegradable cleaner. Never on the glass directly unless it’s already been restored and coated.
- Complete site protection — ground-level protection for landscaping, pedestrian safety barriers, and drainage management during the wash cycle.
Facade power washing is typically quoted per square metre based on building height, accessibility, and the level of soiling. MCST buildings and commercial facilities typically schedule power washing every 12–24 months as part of a scheduled maintenance programme — see our MCST facade glass maintenance programme for contract rates.
Frequently Asked Questions
Do you work on high-rise buildings?
Yes. We handle facade glass restoration for buildings of all heights, with appropriate safety equipment and trained technicians for rope access or elevated work platform operations.
How often should facade glass be professionally restored?
In Singapore’s climate, we recommend professional facade glass treatment every 1–2 years to prevent permanent staining. Buildings near water or in areas with heavy rainfall may require more frequent attention.
Can facade glass be permanently protected against staining?
Nano hydrophobic glass coating significantly reduces staining by preventing water and contaminants from bonding with the glass surface. After restoration, we recommend coating application for long-term protection.
