How Much Does Mandatory Window Inspection Cost in Hong Kong?

The Mandatory Window Inspection Scheme (MWIS) is administered by the Buildings Department (BD). Owners of private buildings aged 10 years or more are required to periodically commission a qualified person to inspect the windows of their units for structural safety and submit a declaration to the BD. The inspection covers window frame condition, sashes, fixings, and fall-prevention measures, ensuring windows do not pose a falling hazard due to deterioration or poor maintenance. The scheme operates on a rolling basis — the BD issues statutory notices to owners of specific buildings each year, and owners who receive a notice must complete the inspection and declaration within the specified deadline or face prosecution.

Mandatory window inspection (MWIS) and home inspection are two entirely separate schemes. Window inspection focuses specifically on window structural safety, is enforced by the Buildings Department, and is only required when an owner receives a statutory notice from the BD. Home inspection is voluntary and typically commissioned before a property purchase or renovation, covering the overall structural and functional condition of a unit — a much broader scope than window inspection alone. Both can be arranged at the same time, but different qualified professionals and fee structures apply to each. Some companies offer combined services, which can reduce overall costs.

不包含。驗窗收費僅涵蓋安全檢驗及向屋宇署提交書面申報，不包括任何維修工程。如驗窗後發現窗戶有結構問題（如窗框變形、螺絲鬆脫、密封膠老化或窗扇無法緊閉），業主須另行委聘持牌承辦商進行維修，維修費用視問題嚴重程度而定，一般由 HK$500 至 HK$5,000 或以上不等。建議業主在申請驗窗報價時，同時詢問驗窗公司是否提供驗後維修服務，部分公司提供驗窗加維修的套餐安排，有助簡化流程。

強制驗窗費用主要受窗戶數目及面積、單位樓層（高層或窗戶難以從室內觸及時需使用外架，費用較高）、驗窗師傅資歷（認可人士收費一般高於一般合資格承辦商）及是否需要加急申報等因素影響。如樓宇窗戶設計複雜（如落地窗、特殊鋁合金框架或非標準窗型），評估所需時間較長，收費亦會相應較高。建議向最少三間持牌驗窗公司索取報價，並確認報價包含向屋宇署提交申報的服務。
