How Much Does Window Cleaning Cost in Singapore — And Can Cleaners Safely Reach High-Floor Glass?

Professional window cleaning in Singapore costs roughly $8–15 per panel, $30–50 per hour, or $150–450 for a whole home. And yes, a trained, insured crew can safely clean the outside glass of a high-floor HDB or condo using reach poles and proper access gear. The dangerous option is you leaning out to do it yourself.

We’re Sureclean. We’ve cleaned over 50,000 homes across Singapore and hold a 4.9-star rating from 1,476 Google reviews, so we’ve seen most of what this island’s windows throw at a crew: sea-salt-crusted full-height condo glass near the coast, casement windows in older HDB flats that hadn’t been opened in years, and BTO handovers still fogged with cement dust. Here’s the Singapore-specific breakdown of what it costs, what’s safe, and how to actually get glass that stays clear.

How much does window cleaning cost in Singapore?

There’s no single rate, because “windows” covers very different jobs. Companies price by panel, by hour, or by flat size. What moves the number up or down is straightforward: how many panels, the window type, the height and access, whether tracks, grilles and mesh are included, and how baked-on the watermarks are.

Treat these as market ranges, not a fixed quote. A 4-room flat where only the inside glass needs a wipe sits at the bottom. A high-floor condo with full-height glass, salt spray, mould in every track and invisible grilles to work around sits at the top. When in doubt, send photos and request a quote. A good company prices off what it actually sees, not a guess.

Can cleaners really clean the outside of high-floor HDB and condo windows?

This is the question every high-floor customer asks, because their window only opens a few inches and the outside glass is filthy. The answer is yes, and the method depends on the window type:

• Casement windows (the ones that swing open): the crew can usually reach most of the outer pane by opening the sash and working across it with a squeegee and an extension pole from inside. Safe, no leaning out.
• Sliding windows: trickier, because a fixed pane sits behind the sliding one. Crews use slim reach poles and angled squeegees to get behind and along the outer track.
• Full-height / fixed condo glass: this is where the equipment earns its keep. Water-fed reach poles (a telescopic brush fed with purified water that dries spot-free) handle most of it, and for facades that genuinely can’t be reached from inside, proper working-at-height access is booked through the building’s managing agent.

The point to hold on to: a real crew never solves a high-floor window by putting a person’s body outside the building. If the outside can’t be reached safely from inside or with a pole, that’s a managing-agent and access-equipment conversation, not a “hold my legs” one.

Is it legal, or safe, to clean your own high-floor windows in Singapore?

Be honest with yourself here. Leaning out of a high-floor HDB or condo window to wipe the outside glass is how people fall, and it’s how a bucket, cloth or squeegee ends up dropping onto someone below. Killer litter and items falling from height are treated very seriously in Singapore and carry real penalties, quite apart from the risk to your own life.

Our standing advice to homeowners: clean the inside glass yourself all you like. For anything that needs reaching, leaning or hanging over the edge, stop and get a crew with the right poles, harness points and public-liability insurance. The few dollars you save doing it yourself are not worth the outcome if it goes wrong. This is also the real reason to hire an employed, insured crew rather than a random freelancer: if something happens at height, the training and the insurance are the entire point.

What’s actually included in a professional window deep clean?

“Window cleaning” done properly is more than the glass. A thorough service covers:

• Glass, both sides: inside and the reachable outside, squeegeed streak-free
• Frames and sills: wiped down, not just the pane
• Tracks and grooves: the channels where dust, dead insects and black mould collect
• Rubber seals and gaskets: degreased and de-moulded
• Grilles and mesh: window grilles, invisible grilles and insect screens brushed and wiped
• Fly screens / retractable mesh: dust and grime removed without stretching the mesh

Always ask what’s included before you book. Some quotes are “glass only,” and the tracks and mould, the part you actually hate, cost extra. Window work often folds into a broader professional spring cleaning or a post-renovation clean, where fine cement and silica dust settles into every track and window groove and needs proper extraction, not a dry wipe.

Why your glass still looks cloudy: rain marks and hard-water stains

You cleaned the window and it’s *still* streaky and cloudy. That’s not you doing it wrong. It’s mineral staining. Singapore rain, sprinkler over-spray and condensation leave water spots that dry and etch onto the glass. Over months they build into a cloudy film that ordinary glass cleaner and a cloth just smear around.

Removing it needs the right chemistry, not more elbow grease: a mild acidic or specialist glass-restoration solution to dissolve the mineral deposit, sometimes a fine polishing compound, then a proper squeegee-and-flood technique to finish spot-free. Near the coast, add sea-salt film to the problem, which crusts fast on exposed condo glass and needs the same treatment. If your “clean” glass has looked permanently hazy for a year, it’s almost always mineral scale, and it’s fixable.

Black mould in the tracks and rubber seals

Open your window track and look at the black gunk in the grooves and along the rubber seal. That’s mould, and it’s a humidity problem, not a dirt problem. Singapore’s constant tropical humidity plus condensation gives mould spores a permanently damp home in the shaded, rarely-cleaned channel of a window track and in the porous rubber gasket.

A dry cloth just pushes it around. Our crews flush the tracks, apply an anti-mould treatment that kills the growth at the root instead of smearing it, detail the grooves with brushes, and wipe the seals down. Left alone, track mould keeps coming back and can spread, which is why humid homes do better having windows done on a schedule rather than treated as a one-off.

How long it takes, and how to prep

A 4-room HDB flat is usually a 1.5–3 hour job. A larger condo or landed home with full-height glass and more panels can run half a day or longer. Heavy watermark restoration and mould treatment add time.

To make it faster and cheaper:

• Clear windowsills and remove ornaments, plants and diffusers
• Unclip removable insect screens if you can, or just tell the crew they’re there
• Point out any windows with stuck locks, broken hinges, or panes you *don’t* want opened
• Flag full-height or fixed glass in advance so the crew brings the right poles
• For condos, check whether the managing agent needs notice for any external access

Is window cleaning worth it, or should you just DIY?

Straight answer: DIY the easy stuff, hire out the hard stuff. If your windows are low, open fully and just need a routine wipe, do it yourself and keep the money. There’s no shame in a cloth and some glass cleaner.

Call a professional when the outside glass is on a high floor and can’t be reached safely; when the glass is permanently cloudy from hard-water or salt staining; when the tracks and seals are black with mould; or when you’ve got full-height condo glass, invisible grilles and mesh screens to work around. That’s the line for us. The moment a job needs height, chemistry or specialist tools, the pro option is genuinely cheaper than the risk or the ruined afternoon. Plenty of homeowners fold windows into a recurring weekly home cleaning plan or a thorough move-in / move-out clean so it never piles up in the first place.

Red flags when hiring a window cleaning company

• No insurance mentioned: for anything at height, public-liability and workman’s insurance are non-negotiable. Ask directly.
• A quote with no site view for high-floor exterior work: reputable crews assess access before they price it.
• Anyone willing to lean or climb out of a high window: walk away. It endangers them and the people below.
• “Glass only” buried in the fine print: confirm whether tracks, seals, grilles and mesh are included or priced separately.
• Cash-only freelancer with no recourse: if they scratch your glass or tear a screen, you want an accountable company, not a phone number that goes dead.

Frequently Asked Questions

How much does professional window cleaning cost in Singapore? Expect roughly $8–15 per panel, $30–50 per hour, or about $150–450 for a whole flat or condo. Price rises with panel count, height and access difficulty, full-height glass, and whether tracks, grilles and mesh screens are included. For an accurate figure, send photos and request a quote.

Can cleaners clean the outside of my high-floor HDB or condo windows? Yes. Crews reach most exterior glass safely from inside using extension poles and squeegees, or water-fed reach poles for fixed panes. Facades that genuinely can’t be reached from inside need proper access equipment booked through the building’s managing agent, never a person leaning out.

Is it legal to clean the outside of my own HDB windows? Cleaning inside glass is fine. Leaning out to wipe exterior high-floor glass is dangerous and risks objects falling from height, which is treated very seriously in Singapore. For any exterior or reach-required work, use an insured crew with the right equipment.

Why do my windows still look cloudy right after I clean them? That haze is usually hard-water or rain-mark mineral staining, sometimes sea-salt film near the coast, etched onto the glass. Ordinary cleaner just smears it. It needs a specialist acidic or glass-restoration treatment and proper squeegee technique to remove.

How do I get rid of black mould in my window tracks and rubber seals? Track mould is driven by Singapore’s humidity and condensation, so wiping alone won’t fix it. You need to flush the tracks, apply an anti-fungal treatment that kills it at the root, and detail the grooves and seals with brushes. On a schedule, it stays away.

How often should I get my windows professionally cleaned? For most Singapore homes, every 3–6 months keeps glass clear and stops track mould building up. Coastal, high-dust or heavy-cooking homes benefit from more frequent cleaning; low-exposure inland flats can stretch longer.
