Sliding window rollers, tracks and safety stoppers

Searches for sliding window repair in Singapore are usually a panel that will not run, or a panel that can be lifted. Those are different faults. Dust, insect bodies and dried rain pack the sill. The published track clean and lubricate is S$60 to S$100. That visit does not replace a roller. If the panel still hops after the track is clear, the roller or the shoe has failed. Exterior rollers are named in the same RW01 catalogue line as rivets and stays: S$180 to S$600, done by a BCA approved window contractor. Homey Furnishing does not swap an exterior roller and call it a hinge visit.

The safety piece is the stopper and the angle strip. The casement guide on this site is explicit: sliding windows need safety stoppers and angle strips so the panel cannot be lifted out of the track by a child or by wind. A missing stopper is not a small extra. It is also not the same part as a casement rivet. No separate stopper price is printed. If the photo shows a missing stopper and an otherwise sound roller, the line is quote on inspection with the approved contractor, not a borrowed roller band. HDB’s sheet for sliding windows also calls for synthetic-resin stoppers at the top of the outer frame, fastened with grade 304 rivets or screws of at least 4mm, at least two stoppers per panel width. That is a specification, not a dollar we invented.

Balcony doors confuse the search. Condo balcony tandem bogie rollers are S$220 to S$480 on the door repair page. They are a door leaf on a bogie, not a bedroom sliding window. A service-yard sliding window in an HDB flat is this page. A full-height balcony sliding door in a condo is the door page unless the photo shows a window panel in a window frame. Say which one, and send the photo of the bottom edge where the wheel sits. We will not price a bogie as a window roller or a window roller as a bogie.

Replacement of the whole sliding frame is the HDB window replacement page. It needs an approved contractor on HDB’s directory and a renovation permit. Like-for-like means sliding stays sliding. HDB does not want a casement dropped into a sliding opening as a casual upgrade. Width limits on a new sliding panel in the parapet guidance run from 500mm to 1200mm where that parapet clause applies. Read the replacement page before you ask a roller visit to become a new frame. Film on a sliding pane that still runs is the heat or privacy page, and it does not fix a dead roller.

Cleaning the track with a steam nozzle is also a published cleaning visit: HDB window, grille and track cleaning from S$120 to S$240 for a 3-room to 5-room flat, done from inside. That is a clean, not a roller. If you only want the glass and the silt gone, book the clean. If the wheel is oval or the panel lifts out, book the contractor path. West-facing tracks collect both sun-baked dust and wind-driven rain. Neither is a reason to remove the stopper so the panel “slides easier”.

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.

Look from inside the room. Do not lean out to test a stay or a pane.

1. Photograph the bottom track and the stopper at the top of the frame.
2. Do not lift the panel out to “show the roller”.
3. Say whether this is a window or a balcony door.
4. If the wheel is the failure, expect the RW01 roller band.
5. If the track is only filthy, the S$60 to S$100 clean may be the whole job.

The building changes the permission. It does not invent a second price.

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.

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

• 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.
• Vacuum the track and send a photo of what is left. If the panel still jumps, it is a roller or a stopper, not more grease.

Three published sentences cover most of this search. A missing stopper is the one that stays quote on inspection.

Anything not in that table is quote on inspection.

WhatsApp the photos to +65 8561 0630. The reply uses a band already printed on HomeySG, or it says quote on inspection.
