Public Housing Window Inspection Guide: Compulsory Steel Window Inspection
Many owners are unaware that old-style steel windows are also subject to compulsory window inspection under the law. However, most engineering companies in the market refuse to inspect steel windows because they are decades old, mostly fail to meet current standards, and the safety and legal risks borne by inspectors are far higher than those for aluminum windows. They often insist on direct replacement upon seeing steel windows and are unwilling to conduct inspections. In contrast, EJW believes that such a one-size-fits-all refusal to inspect is highly unreasonable for owners. The inspection principles for steel windows are completely different from those for aluminum windows. We insist on conducting objective assessments based on steel window-specific standards, and will never aggressively promote aluminum window replacement to avoid risks, thereby genuinely protecting owners’ rights and interests.
Professional Full Aluminum Window Replacement Works: Thoroughly Eliminate Hidden Risks of Old Windows
Whether it is rusted and aged steel windows in public housing estates or deformed old aluminum windows in private residential buildings, facing metal fatigue and water leakage during typhoons and heavy rain, repeated minor repairs only treat the symptoms but not the root cause. Full aluminum window replacement is the one-time, permanent solution to safeguard home safety.
EJW provides high-quality window replacement solutions with equal emphasis on two major customer groups:
-
- Public Housing Steel-to-Aluminum Window Replacement: Strictly following the statutory standards of the Housing Department and Buildings Department, we safely remove rusted steel windows and upgrade them to modern aluminum windows, improving airtightness and sound insulation.
- Old Building Aged Aluminum Window Replacement: For window frames that have become tilted in private residential estates, our experienced aluminum window engineering team performs structural repositioning and installation to completely resolve metal fatigue issues.
Public Housing Window Inspection: Essential Information for Steel Window Inspection
Steel Window Inspection Pass Guide! Professional breakdown of the four core inspection points to help you easily handle compulsory window inspection
Key Point 1: Check Smooth Operation and Integrity of Components
Old-style steel window hinges are exposed to the outdoors for long periods. Without proper maintenance and regular lubrication, they are highly prone to severe rusting, resulting in stuck or extremely difficult operation. During steel window inspection, it is essential to carefully test whether the windows operate smoothly and thoroughly check whether the core hardware components are deformed or even rusted and broken, ensuring that the window sashes do not pose any risk of falling during daily use or in typhoons.
Key Point 2: Assess Whether Air-Conditioner Installation Meets Safety Standards
Many units overlook the structural safety of steel windows when installing air-conditioners. The compliant practice is to first remove the original operable window sash before placing the unit. If, for convenience, the operable sash is not removed and the air-conditioner is simply forced into the opened steel window and locked in place, leaving the sash in a permanently open and suspended state, this absolutely does not comply with safety standards and is a common pitfall that will result in failure during compulsory window inspection.
Key Point 3: Examine the Condition of Surface Anti-Rust Paint (Painting) Protection
Painting is the core line of defense protecting steel windows from oxidation. Iron materials are highly susceptible to moisture and rust, but with regular and adequate painting maintenance that completely isolates the metal from moisture, steel windows can actually remain strong and intact for a long time. Inspection focuses on observing whether there is paint peeling, exposed metal, or deep rusting on the window frames, to determine whether the overall structural strength of the steel window remains safe and stable.
Key Point 4: Confirm Market Availability and Replaceability of Damaged Parts
Steel windows are products from decades ago, and most related hardware parts have long been discontinued in the market. The biggest challenge during inspection is assessing whether damaged parts can still be successfully replaced. If certain core components (such as specific types of steel window hinges) are already obsolete and have no substitutes, the damaged steel window will definitely fail the Buildings Department’s compulsory window inspection, and full replacement such as steel-to-aluminum window replacement must be considered.

Registered Personnel Inspection and Checking
Inspection Fees and Refund
In the early days of EJS, the founder carefully considered one question:
For every on-site inspection, should we send a general construction worker, or should a Buildings Department registered personnel with relevant qualifications attend in person?
Simply dispatching ordinary workers, skipping plan reviews, or even providing online quotations based solely on photos supplied by clients can indeed reduce costs and allow free inspections. However, practical experience has shown that photos often fail to fully reflect actual site conditions, and the final scope of works and costs may differ significantly from the initial estimate. More importantly, without professional judgment from qualified personnel, and without referring to relevant plans and information when necessary, certain works may carry procedural and compliance risks.
Therefore, the founder established a principle that remains unchanged to this day:
Every home deserves to be treated with care. Qualifications, procedures and professional judgment are all indispensable.
Even if this approach may result in the loss of some clients, the company continues to charge an inspection fee of approximately HK$300 to HK$500, arranging for relevant registered personnel to conduct on-site inspections in person, and basing assessments and quotations strictly on actual site conditions. We do not replace professional judgment with photos, nor do we issue formal project quotations based solely on photographs.
If the client subsequently decides to engage the company for the works, the inspection fee already paid will be fully refunded.
This is not merely a choice of charging method, but a decision that upholds work quality, professional responsibility, and accountability towards the client’s home.
This commitment has remained unchanged since the company’s founding.

EJW Quality Standard Aluminium Windows
Many property owners wish to first understand the approximate cost of aluminium window replacement online, but it is difficult to summarise with a single price. Factors such as the structure and location of each unit, whether scaffolding is required, as well as the window opening method, installation position and structural design, all affect the final quotation. Many companies in the market attract customers with lower prices, yet overlook the reality of varying aluminium window quality — if substandard products are chosen, short-term cost savings may appear, but long-term maintenance, safety and lifespan risks will ultimately be borne by the owners themselves.
We believe that as a professional aluminium window company, we should not use low prices to conceal quality risks. Therefore, EJW only selects aluminium window products from factories that have undergone strict inspection and are confirmed to be of high quality, adhering to “high quality at a reasonable price” rather than “low quality at a low price”. The price ranges listed on the website are for preliminary reference only; actual costs must be accurately assessed and suitable solutions provided after an on-site inspection.

🛠️ One-Time Permanent Solution: Professional Steel-to-Aluminum Window Replacement and Aged Aluminum Window Replacement
Stop living in constant worry about window leakage and difficult operation! EJW delivers a thorough window “transformation” project. Whether it is bidding farewell to heavy, rusted old steel windows or completely removing and replacing aged, deformed aluminum windows, we insist on assigning experienced senior craftsmen to take full responsibility. With structural remodeling as the technical core, our team recalibrates and repositions the windows for each unit and applies the highest-standard deep anti-leakage techniques. We promise transparent pricing and will directly equip your home with the strongest, most beautiful wind and rain protection shield, eliminating water seepage and falling window fears once and for all!
Key Point 1: On-Site Visit by Engineering Team for Accurate Survey and Precise Measurement
Aluminum window replacement works must never rely on “photo estimation” or theoretical planning. Our engineering personnel must personally visit the unit to conduct the most accurate window dimension measurements. More importantly, we need to assess the difficulty of erecting scaffolding on the external wall, observe the surrounding building environment, and identify any potential safety hazards that may affect high-altitude operations. Only through on-site inspection can we ensure the construction plan is foolproof.
Key Point 2: Strictly Adhere to Official Original Approved Plans to Prevent Illegal Structural Alterations
Whether for public housing, Home Ownership Scheme, or private residential units, any modification to the building’s original aluminum window structure is strictly prohibited. Even for public housing units, the Housing Department has specific design guidelines and plan specifications. Before commencing work, we must verify the unit’s original statutory plans to confirm the compliant design. If the owner has special requirements to change the window design, we will deploy engineers to perform fresh structural calculations and submissions, ensuring the works are 100% legal and eliminating the risk of future Buildings Department orders to reinstate or encumbrance on the property title.
Key Point 3: Comprehensive HK$20 Million Insurance and Proper Administrative Submission – No Risky Construction
High-altitude window replacement involves extremely high legal and safety responsibilities. We promise that all aluminum window replacement works will only commence after securing sufficient insurance coverage (including up to HK$20 million third-party liability insurance) and completing proper submission procedures with the estate management office or management company. Many small window companies in the market bypass formal procedures and engage in “illegal hasty construction” to save costs. Should any accident occur, owners would face unlimited legal liabilities. We insist on following the most proper procedures to provide you with the most reliable protection.
Frequently Asked Questions
Is the quotation for full aluminum window replacement works inclusive of demolition and removal of old windows? Will there be any hidden waste disposal charges?
Our quotation is absolutely one-stop, all-inclusive with transparent pricing! The project fees from EJW fully cover: safe dismantling of old steel windows or old aluminum windows, removal and disposal of all waste materials, and basic site cleaning after completion. We promise there will be no wordplay or tricks. After aluminum window replacement works are completed, we will never add any extra charges under names such as “waste transportation fee” or “waste disposal fee”. This allows you to clearly understand the budget with no worries.
I live in public housing or Home Ownership Scheme housing and want to replace old steel windows with aluminum windows. Will this violate the Housing Department’s structural guidelines?
Absolutely not! We place great importance on legality and compliance. Before commencing steel-to-aluminum window replacement, our team will first verify the original statutory plans of your building and the design guidelines of the Housing Department (or Buildings Department) to ensure the replacement aluminum windows fully comply with official specifications. If the owner has special design requirements, we will deploy engineers to perform fresh structural calculations and submissions, ensuring the works are 100% legal and eliminating the risk of future reinstatement orders or encumbrance on the property title from the Buildings Department.
Aluminum window replacement works require scaffolding. Is your insurance coverage sufficient? Does the owner need to apply to the management office themselves?
Rest assured, we handle all complicated administrative procedures on your behalf! High-altitude aluminum window replacement is a high-risk operation. We insist on following the most proper procedures and will never engage in “illegal hasty construction”. Before starting work, we will formally complete the compliant submission with your estate management office and purchase adequate protection for every project — including up to HK$20 million third-party liability insurance and employees’ compensation insurance — reducing the owner’s legal and safety risks to zero.
After receiving the compulsory window inspection notice, do all the old steel windows or old aluminum windows in my flat have to be fully replaced?
Not necessarily! We uphold a conscientious approach with the principle of “transparent pricing and no unnecessary works”. After our craftsmen conduct on-site steel window inspection or public housing window inspection, if the structure of your old windows is still safe and only minor hardware parts (such as hinges or gaskets) need replacement to meet the standards, we will never force you to carry out expensive full aluminum window replacement. We will only recommend a one-time permanent full upgrade when old steel window parts are obsolete and irreplaceable, or when the window frames are severely deformed, tilted, or show signs of metal fatigue.
How many days does a full “steel-to-aluminum window replacement” or aluminum window replacement project usually take? Do I need to move out temporarily?
For a standard residential unit, full aluminum window replacement works (including scaffolding erection, removal of old windows, installation of new windows, and deep anti-leakage plastering) can usually be basically completed within 4 to 5 working days. During construction, there will be short periods of drilling noise and localized dust. Our craftsmen will implement basic dust protection measures. Owners do not need to move out during the works and can continue living in the unit as usual, with minimal impact on daily life.

“One window may seem insignificant, but it carries the life safety of the entire family and the stability of a household. In Hong Kong, whether facing old steel windows in public housing or aged aluminum windows in private buildings, owners often feel lost when receiving compulsory window inspection notices. I have seen many companies in the market refuse to inspect steel windows outright because they find it troublesome, or engage in illegal ‘hasty’ construction during aluminum window replacement. This deeply pains me.
