Cracked window glass is an approved contractor
A cracked window pane is not a silicone skin and not a film. HDB’s own sheet says to engage a BCA-approved window contractor listed with HDB to replace cracked glass and the gasket. No per-pane price is published. Quote on inspection. Shower glass is a different page.

How it works
- 1
Send one photo of each window from inside the room, with the block and whether the home is HDB, condo or landed.
- 2
We match a band already printed on HomeySG, or we say quote on inspection.
- 3
Exterior rivets, stays, rollers and glass are named as a BCA approved window contractor. Film on intact glass is not a sash replacement.
- 4
You confirm the scope before anyone comes. Curtains, blinds and roller shades stay off the booking.
What this job actually is
Window glass replacement shows up after a slam, a moved furniture corner, or a crack that has been growing from a chip. HDB’s common-problems sheet is plain about it: engage a BCA-approved window contractor listed with HDB to replace cracked glass panes and the rubber gasket, with the new gasket fixed tightly into the inner frame. A loose gasket that is still flexible can be pushed back into its groove. A brittle gasket is the contractor, even before the glass falls. Homey Furnishing does not cut a replacement pane and does not lean out to measure one.
The window repair page says RW01 covers exterior components, and its examples include glass. The comparison table groups those exterior works at S$180 to S$900 a window. The catalogue line that has its own low and high is rivets, stays or rollers at S$180 to S$600, which does not say “one pane of glass”. This page will not invent a 5mm or 6mm rate, a tempered surcharge or a transport fee. The measured pane is quote on inspection. If the contractor’s scope matches the grouped exterior band, that is the sentence already printed. If the crack has taken the frame with it, you are on the replacement page and a permit, not a glass-only visit.
Safety while you wait is ordinary and specific. Keep children and pets away from the pane. Do not cover a crack with film, tape as a permanent fix, or a curtain and call it safe. Film on a cracked pane hides the damage and does not hold tempered glass together as a repair. A child restrictor on a cracked sash is the same mistake. If the crack runs to the edge and the stay is also loose, treat it as a fallen-window risk and use the safety guide. Penalties for a fallen window are already stated there. We do not repeat them as a scare price.
Other glass in the home is a different invoice. A shower screen with a chipped corner uses the shower-screen page, where a new sliding frameless screen is published around S$680 to S$1,000 and a seal-and-hinge repair is S$90 to S$350 when the glass is intact. A black-edge bathroom mirror is S$160 to S$350. A glass balustrade is the staircase railing page. None of those bands are a bedroom window pane. Say “window” in the first photo so the reply does not quote a mirror.
Condos often treat the outer pane of a facade as common property. Ask the MCST before a contractor changes the tint or the thickness the elevation was built with. Landed houses still use an approved contractor for the window type BCA regulates, and the upper floor is measured from inside. An insect screen, a grille or frosted film can wait until the new pane is in. They are not a substitute for glass.
Homey Furnishing Pte. Ltd. (ACRA UEN 202018148K), 27 Mandai Estate, #06-10 Innovation Place, Singapore 729931, invoices permit-exempt window work done from inside the flat. V On Construction Pte. Ltd. (ACRA UEN 201611708H), on the HDB Directory of Renovation Contractors, invoices an HDB renovation permit when the window scope needs one. The exterior rivets, friction stays, rollers and glass are done by a BCA approved window contractor registered under workhead RW01. Homey Furnishing is not that RW01 contractor.
Curtains, blinds and roller shades are not part of this booking. Fabric is a different product, and these pages do not quote it.
What to do first
Look from inside the room. Do not lean out to test a stay or a pane.
- Photograph the crack from inside without pressing the glass.
- Do not pull loose pieces out over the corridor.
- Note whether the frame is bent as well as the glass.
- Keep shower glass and mirrors off this booking.
- Expect quote on inspection for the pane.
| What you see | Safe check | Stop |
|---|---|---|
| Crack in the window pane, frame looks straight | Approved contractor and a new gasket | Quote on inspection |
| Frame is twisted as well | Replacement page, permit if it is HDB | Not a glass-only guess |
| Shower panel is chipped | Shower-screen page | S$90 to S$350 if the glass can stay, or the new-screen rows |
| Only the gasket is loose and still flexible | Push it back, HDB’s own first step | Brittle gasket is the contractor |
HDB, condo and landed
The building changes the permission. It does not invent a second price.
| Question | HDB | Condo | Landed |
|---|---|---|---|
| HDB | Approved contractor listed with HDB for a cracked pane and gasket. A new frame is a permit. | Do not tape the pane and leave it over a corridor. | Film is not a repair. |
| Condo | Check whether the outer glass is common property. Match the elevation tint if the MCST requires it. | A by-law can forbid a different reflective glass. | Interior film after the repair is a separate quote. |
| Landed | Same contractor rule where BCA covers the window. Measure from inside. | A shopfront pane may be the commercial glass page. | Upper storeys are not a ladder leaned on the sill from outside by us. |
How you're charged
How you're charged
A window job that already has a sentence on HomeySG uses that sentence. Nothing in this table is a fuel surcharge, and the hour is not added on top of a band unless the written scope says so.
| Charge | What it covers | 2026 |
|---|---|---|
| Published window band | The photo matches a row already on a window page | That row |
| Interior reseal | Silicone or PU from inside the room | S$180 to S$380 a window |
| Handle replacement | The handle row on the window repair page | S$60 to S$120 |
| Track clean and lubricate | Sludge in the track, not a new roller | S$60 to S$100 |
| Exterior rivets, stays or rollers | A BCA approved window contractor, RW01 | S$180 to S$600 |
| Film, stickers, mesh, a restrictor, or a full new window | No catalogue row for that product | quote on inspection |
Who may do the work
Who is allowed to touch the window
HDB’s window-works guidelines require a BCA approved window contractor listed in HDB’s directory for installation and replacement, and an HDB renovation permit before that work starts. BCA registers that contractor under workhead RW01. Retrofitting replaces aluminium rivets in variable-geometry stays with type 304 stainless steel. Homey Furnishing does not issue that rivet.
- Interior silicone or PU reseal, at S$180 to S$380 a window, is the exempt interior job on the window repair page.
- A handle at S$60 to S$120 is that published row. A failed stay or rivet is not a handle.
- Film on intact glass is not a sash replacement. On an HDB flat, film over existing window or balcony-door glass does not need a permit when it is non-reflective or not above 20% reflectance.
- Service-yard and balcony parapet grilles need a permit. Flats handed over from 1 July 2007 use HDB’s approved grille designs. Older blocks may take an internal grille that does not protrude, without that permit.
- A condo facade is the MCST’s elevation. Reflective film, a grille and an external screen are uniformity questions before anyone sticks or drills.
- Curtains, blinds and roller shades are not quoted here.
- Nobody leans out of the casement. High glass is cleaned from inside.
Ways to keep the bill smaller
Ways to keep the bill smaller
- Photograph every opening before a film roll, a mesh panel or a grille is cut. A wrong reflectance or a wrong grille design is a wasted visit.
- Put the windows in one room on the same visit. A second trip is a second booking.
- If the track is only dirty, the published clean is S$60 to S$100. That is not a new roller.
- If the stay is rusty, stop. Film and a child lock on a failing sash do not make it safe. The approved contractor comes first.
- Photograph the crack from inside and keep people away from the pane. Do not pull the shard out.

Price, or quote on inspection
No per-pane window price is published. The grouped exterior band is shown so it is not mistaken for a new number, and so shower glass is not used by accident.
Anything not in that table is quote on inspection.

Frequently Asked Questions
How much does it cost to replace window glass in Singapore?
Quote on inspection. No per-pane price is published. HDB tells owners to use a BCA-approved window contractor for a cracked pane and the gasket.
Can silicone hold a cracked pane?
No. Sealant is for a sound perimeter, at S$180 to S$380 a window. It is not a skin over a crack.
Is the S$180 to S$900 figure a glass price?
It is the window repair page’s grouped band for exterior RW01 works, and the examples include glass. A measured pane is still confirmed on inspection rather than assumed to be that whole band.
Can you replace a shower screen here?
No. Shower glass has its own page. A seal and hinge repair is S$90 to S$350 when that glass is intact.
Do you lean out to measure the pane?
No. Photos are taken from inside. The approved contractor measures the glass.
