# Glass & Aluminium Works in Singapore

Window installation or replacement in Singapore must be done by a BCA-approved window contractor (workhead RW01) using trained installers, and in HDB flats the contractor must also be HDB-registered and get a permit. Owners must also replace aluminium rivets on casement windows with stainless steel ones under BCA rules.

## Licences
- **BCA Approved Window Contractor (RW01)** (Building and Construction Authority (BCA), required): Window installation and retrofitting must be done by an approved window contractor with a BCA-certified trained window installer (or a GB1/GB2 builder). Using unapproved installers can lead to a fine of up to $5,000, up to six months' jail, or both. Check: https://www1.bca.gov.sg/public/private-property-ownership/approved-window-contractors
- **HDB-registered window contractor and renovation permit** (Housing & Development Board (HDB), required): In HDB flats, window replacement and window grilles must be installed by BCA-approved window contractors registered with HDB, and window replacement requires HDB approval. Check: https://www.hdb.gov.sg/managing-my-home/renovation-and-maintenance/renovation/renovation-guidelines

## How to choose
- Check the contractor on BCA's directory of approved window contractors before signing, and for HDB flats confirm they are HDB-registered.
- Ask for the profile system, glass thickness and whether the glass is tempered or laminated, especially for shower screens and full-height windows.
- For invisible grilles, ask for the cable material and spacing, and whether the installation suits your window type.
- Ask whether casement window rivets will be replaced with stainless steel ones, which BCA requires owners to do.
- Get warranty terms for glass, hardware and water-tightness in writing.

## Red flags
- Window installers who cannot show BCA approval or a trained installer certificate.
- Shower screens quoted without stating tempered glass.
- Offers to replace HDB windows without an HDB permit.

## FAQs
### Who can replace windows in my HDB flat?
Only a BCA-approved window contractor using BCA-certified trained window installers may install or replace windows, and for HDB flats the contractor must also be registered with HDB. Window replacement needs HDB approval. Using an unapproved installer can lead to a fine of up to $5,000, up to six months' jail, or both.

### Do I need to change my window rivets?
Yes, if you have casement windows. Under BCA's retrofitting requirements, homeowners must replace aluminium rivets on casement windows with stainless steel rivets, because aluminium rivets corrode and have caused windows to fall. Failing to do so can lead to a fine of up to $5,000, up to six months' jail, or both. Check windows at least twice a year.

### Are invisible grilles allowed in HDB flats?
Window grilles in HDB flats must be installed by BCA-approved window contractors registered with HDB and follow HDB's guidelines. Many HDB owners install invisible grilles for child safety, but confirm with the contractor that the product and installation meet HDB requirements and that the grille does not block emergency access.
