Check the windows in your Punggol HDB flat at least every six months. HDB and BCA guidance emphasises regular maintenance because loose, worn or deteriorated parts can affect window safety. A window that still opens is not necessarily a window whose components are in good condition.
For casement windows, look for rusty or loose fasteners; for sliding windows, check the safety stoppers and angle strips. HDB’s guidance uses a Check, Clean and Change approach. If you are unsure what you are looking at, engage an approved window contractor for inspection.
For window repair, replacement or retrofitting in an HDB flat, use a BCA-approved window contractor listed with HDB. Confirm the contractor’s current listing before booking. This guide helps Punggol households organise inspection and follow-up; it cannot certify a window from its appearance.

Put the check on the household calendar
Choose two dates roughly six months apart and record the result for each room. This practical routine is easier to maintain than waiting until a window becomes difficult to operate. Include rarely opened rooms rather than checking only the living room.
Keep a short record of the inspection date, concerns and completed work. If someone else handles the next check, they will know which component previously required attention.

Match the check to the window type
HDB’s maintenance guidance distinguishes casement-window fasteners and moving parts from sliding-window tracks, safety stoppers and angle strips. It advises replacing aluminium rivets with stainless steel through an approved contractor, and replacing worn sliding-window safety parts through an approved contractor.
Ask the contractor to identify your window type and explain any unfamiliar component. A resident’s observation is useful, but it should not become a do-it-yourself instruction to remove or replace load-bearing hardware.

Separate cleaning from repair
Cleaning a track can be routine upkeep; diagnosing a loose panel or changing its fittings is a different task. Follow the manufacturer’s and official maintenance guidance for accessible cleaning. Do not lean outside or detach a panel to reach an awkward surface.
If a window seems insecure, stop operating it and arrange professional assessment promptly. Keep children away from the affected window. Do not keep testing it repeatedly to demonstrate the fault.

Use the directory linked from HDB’s window-maintenance guidance. BCA also provides approved-contractor information. Confirm the business name against the current listing rather than relying solely on an advertisement claiming approval.
Ask for a written scope identifying the window, proposed work and parts involved. Clarify what inspection, documentation and follow-up are included, and keep the final invoice with your maintenance record.

Tell the contractor how many windows need checking, which ones concern you and whether there were previous repairs. Arrange clear access inside the flat and supervise children elsewhere while the work takes place.
Afterwards, ask what was changed and when the next check is due. A repaired window joins the same continuing maintenance routine; the completion of one job does not remove the need for future checks.
