HDB & Condo Scope Review

Window Installation Singapore: HDB & Condo Price Guide

Quick answer: window installation Singapore

Planning ranges start around S$600 per casement opening and S$1,200 per sliding opening. HDB replacement needs a renovation permit and an appointed BCA Approved Window Contractor listed with HDB; condo requirements depend on the MCST and the exact window scope.

A S$10 fuel surcharge applies to every visit. No additional standard call-out or inspection fee applies. Urgent service or a customer-requested appointment time adds one S$30 fee, subject to technician availability and confirmation. The S$30 is a separate service fee. Pricing terms.

Compare a window replacement scope before committing. We review property type, opening sizes, frame and glazing, access, removal, waterproofing, safety barriers and approval requirements, then identify the contractor details and exclusions in the written quote. If the existing window stays in place and you only need an independent metal barrier, use the window security grille installation quote guide instead.

Full-height, three-quarter-height, bay-window and safety-barrier-integrated work is not treated as a standard price item. It needs property-specific assessment and the required HDB, BCA, professional or MCST checks before a quote can be confirmed.

HDB, BCA and Condo Checks Before Quoting

For HDB flats, the HDB window works guide requires a renovation permit for replacement work and a BCA Approved Window Contractor listed with HDB. The BCA window safety guide explains approved-contractor, trained-installer and completion-report requirements. Condo owners should confirm MCST by-laws, approved colours or profiles, work hours, access and deposit requirements before scheduling.

Frequently Asked Questions

Does HDB window replacement need a renovation permit?

Yes. HDB says a renovation permit is required for all window replacement work, and the appointed BCA Approved Window Contractor listed with HDB must apply before work starts.

Who can replace windows in an HDB flat?

Use a BCA Approved Window Contractor listed with HDB. The assigned contractor and trained installer details should be confirmed before work starts.

Can a full-height or bay window simply be replaced?

HDB generally does not allow full-height, three-quarter-height or bay-window replacement except where a damaged frame needs complete replacement and the required approvals are obtained. Safety barriers may require additional professional assessment.

What information is needed for a window quote?

Send property type, postcode, opening count, approximate sizes, current window type, desired frame and glazing, whether it is replacement or a new opening, safety-barrier details, photos and access or timing constraints.

What changes the window installation price?

Opening size and count, frame and glazing specification, hardware, removal and disposal, access, waterproofing and making-good, permit or MCST requirements, and safety-barrier or structural scope change the final price.

What warranty should the written quote show?

The written quote should name the assigned contractor and state parts, workmanship and supplier coverage. HDB's current terms for approved window contractors require at least three months for replaced parts and one year for total replacement.
