HDB window cleaning in Singapore sounds simple until you’re on your fifth floor leaning out with a wet cloth. This 2026 guide covers everything: what’s actually unsafe about DIY, when professional makes sense, how much it costs, and what good contractors do differently.
The HDB window problem
Most HDB windows in Singapore are casement or sliding windows with grilles. Dust, bird droppings, and tropical rain streaks accumulate on both the inside AND outside surfaces. Reaching the outside pane without leaning out is genuinely dangerous — HDB falls from height are a leading cause of residential accidents in Singapore.
Three realities most Singaporeans ignore:
- Grilles make cleaning harder, not easier. You can’t get a cloth between the bars without pushing it to the outside pane — one slip and your arm or cloth goes out.
- Weather matters. Humid days leave streaks. Rainy days are dangerous. The 30-minute window of “good weather” shrinks fast in Singapore.
- Frames + tracks + sills accumulate more grime than panes. People focus on glass; the real build-up is in the frame grooves.

When DIY is reasonable
- Ground-floor HDB — low or no fall risk.
- Interior panes only — you don’t need to lean out.
- You have a telescopic squeegee + the patience to not rush.
- You own a proper window-cleaning squeegee (not a cloth).
When to hire a pro
- You live above the 3rd floor and your windows don’t have external access panels.
- You have grilles.
- You have multiple windows + a limited weekend.
- You’re elderly or have mobility limits.
- You’re cleaning for a sale / handover and want streak-free professional finish.
- You’re cleaning as part of post-renovation prep (add-on cost drops significantly when bundled).
What a professional window clean actually covers
- Interior pane squeegee (streak-free).
- Accessible exterior pane (via grille openings or balcony access).
- Window frame and groove deep clean.
- Grille wipe + rust-prevention treatment (add-on).
- Window track + drainage hole clearing.
- Insect screen vacuuming (add-on).
DIY mistakes that make things worse
- Using a cloth, not a squeegee. Cloth leaves fibres + streaks. Even cheap S$8 squeegees work better.
- Cleaning in direct sunlight. Solution dries too fast, leaves ring marks.
- Vinegar + sun = permanent haze on tinted glass. Use pH-neutral soap on tinted windows.
- Spraying cleaner directly on frame. Overspray drips to downstairs neighbour. Spray cloth, wipe frame.
- Pulling the squeegee down then starting at the top again. Always one direction — top-left to bottom-right in strokes.
