Mandatory Window Inspection Cost Guide: How Is the Price Calculated? Fees, Repair Costs & Money-Saving Tips
When you receive a mandatory window inspection notice from the Buildings Department, the question owners care about most is usually just one — how is the inspection price actually calculated? Market quotes range from a few hundred to several thousand dollars, so what exactly is included, and are there hidden charges? This guide breaks the mandatory window inspection cost into three parts — inspection fee, repair fee and documentation — with reference prices, the factors that affect them and the government subsidies you can apply for, helping you know where you stand before hiring a technician and avoid getting caught out.
What Is Mandatory Window Inspection? Why Did You Get a Notice?
The Mandatory Window Inspection Scheme (MWIS) is run by the Buildings Department under the Buildings Ordinance, mainly targeting buildings aged 10 years or above. The Buildings Department issues a statutory notice to owners of targeted buildings, requiring them to appoint a Qualified Person to inspect all windows in the unit and, where necessary, supervise the repairs.
After receiving the notice, owners must complete the inspection and repairs within the specified period and submit the compliance documents. Missing the deadline or failing to comply may lead to prosecution and fines, so understanding the process and cost early is important. For the full set of steps after receiving a notice, see the 5 steps after a mandatory window inspection notice.
How Is the Inspection Price Calculated? Breaking Down the 3 Parts
Many owners assume the inspection is a single flat fee, but the overall cost usually consists of the following three parts:
In other words, if the windows are in good condition and need no repairs, the cost is only the inspection and documentation fees; if repairs are needed, the repair fee is the main variable in the overall cost.
The 5 Factors That Affect Inspection Cost
From the same notice, the final cost can vary greatly between units, mainly depending on the following factors:
Inspection + Repair Reference Prices
Below are Amgen's reference starting prices; the actual cost is based on the quote after an on-site assessment by a technician:
| Service Item | Reference From | Notes |
|---|---|---|
| Mandatory window inspection (per unit) | From $250 | Inspect windows and submit Form MWI1 to the Buildings Department |
| Safety Accessories Works (hinges + handles) | From $370 | Replace hinges and handles to restore safe operation |
| Four-Treasure Works | From $250 | Hinge, handle, inner and outer weatherstrip replacement + silicone waterproofing |
| Complete Works | From $2,000 | Four-Treasure plus full waterproofing, 3-year warranty |
Note that only a licensed minor works contractor can submit a compliant window inspection report (Form MWI1) to the Buildings Department. Amgen's licence number is MWC 316/2021, and inspection and repairs can be handled in one stop without hiring separately. For report details, see the Form MWI1 window inspection report explained.
Is There a Government Subsidy? Grants and Money-Saving Tips
If you're worried about the repair cost, there are in fact several ways to ease the burden:
A Real Scenario: A Three-Bedroom Flat Receives an Inspection Notice
Take a common scenario: an owner of a three-bedroom flat in a private estate receives a mandatory window inspection notice, with 8 windows in total. After an on-site assessment, the technician found that 3 of the windows had oxidised hinges, 2 handles were loose, and some weatherstrips had hardened.
Amgen completed the inspection, replaced the hinges and handles, renewed the weatherstrips and submitted Form MWI1 all together. Because inspection and repairs were handled in one go, the owner didn't need two separate companies and saved on repeat visits. The overall cost was clearly itemised after assessment, with no hidden charges. If you're still deciding which company to hire, start with Amgen's mandatory window inspection service.
Frequently Asked Questions
Does mandatory window inspection always cost money? Can I inspect it myself?
Mandatory window inspection must be carried out by a Qualified Person, and owners cannot inspect and submit the report themselves, so the inspection fee is unavoidable. However, if the windows are in good condition and need no repairs, the overall cost is limited to the inspection and documentation fees. Maintaining your windows early is the most effective way to reduce inspection costs.
A quote is very cheap — is it necessarily good value?
Not necessarily. Some low quotes may exclude documentation, scaffolding or certain repair items, so the final bill can end up higher. It's best to ask for an itemised quote and confirm whether a licensed contractor (such as MWC 316/2021) submits the documents to the Buildings Department, so you can genuinely compare.
Can repair costs be subsidised?
Yes. Eligible elderly or needy owners can apply for the Urban Renewal Authority's repair assistance scheme to help cover inspection and repair costs, up to $80,000. A professional company can help handle the application procedure and eligibility requirements.
Conclusion
The cost of a mandatory window inspection is not a single figure but consists of three parts — inspection fee, repair fee and documentation — with the actual cost depending on the number and condition of your windows. Understanding the fee structure early, getting a clear quote and making good use of government subsidies lets you keep your budget under control.
