Loose hinges, aging rubber seals and water seepage during the rainy season are common problems affecting almost every building. Owners often only discover the issue when obtaining quotations, and it is not uncommon for the same problem to attract vastly different charges \u2014 sometimes differing by more than double. This article, written from the perspective of an engineering team registered with the Buildings Department, breaks down the common causes of failures in <strong>aluminium window repairs<\/strong>, reasonable fee ranges, and the pricing traps that owners are most likely to fall into, so you can be fully informed before engaging any repair works.<\/p>\n<h2 id=\"table-of-contents\">Table of Contents<\/h2>\n<p>&nbsp;<\/p>\n<ul>\n<li><a href=\"#table-of-contents\" rel=\"noopener noreferrer nofollow\">Table of Contents<\/a><\/li>\n<li><a href=\"#key-takeaways\" rel=\"noopener noreferrer nofollow\">Key Takeaways<\/a><\/li>\n<li><a href=\"#common-failure-types\" rel=\"noopener noreferrer nofollow\">Five Common Types of Aluminium Window Failures<\/a><\/li>\n<li><a href=\"#hinge-replacement-cost\" rel=\"noopener noreferrer nofollow\">Aluminium Window Hinge Replacement: Cost and Process Details<\/a><\/li>\n<li><a href=\"#seal-replacement-cost\" rel=\"noopener noreferrer nofollow\">Aluminium Window Rubber Seal Replacement: When Replacement is Necessary<\/a><\/li>\n<li><a href=\"#water-leakage-repair\" rel=\"noopener noreferrer nofollow\">Aluminium Window Water Leakage Repair: Diagnosis Before Commencing Work<\/a><\/li>\n<li><a href=\"#cost-comparison\" rel=\"noopener noreferrer nofollow\">Comparison Table of Various Repair Costs<\/a><\/li>\n<li><a href=\"#mandatory-inspection\" rel=\"noopener noreferrer nofollow\">Mandatory Window Inspection Scheme and Its Relation to Repairs<\/a><\/li>\n<li><a href=\"#choosing-contractor\" rel=\"noopener noreferrer nofollow\">How to Choose a Reliable Aluminium Window Repair Contractor<\/a><\/li>\n<li><a href=\"#faq\" rel=\"noopener noreferrer nofollow\">Frequently Asked Questions<\/a><\/li>\n<li><a href=\"#references\" rel=\"noopener noreferrer nofollow\">References<\/a><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2 id=\"key-takeaways\">Key Takeaways<\/h2>\n<p>&nbsp;<\/p>\n<table style=\"min-width: 50px;\">\n<colgroup>\n<col style=\"min-width: 25px;\" \/>\n<col style=\"min-width: 25px;\" \/><\/colgroup>\n<tbody>\n<tr>\n<th colspan=\"1\" rowspan=\"1\">Key Summary<\/th>\n<th colspan=\"1\" rowspan=\"1\">Detailed Explanation<\/th>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Hinge replacement is the most common repair item<\/td>\n<td colspan=\"1\" rowspan=\"1\">Aluminium window hinges in Hong Kong generally have a service life of ten to fifteen years. Once past their lifespan they tend to loosen or fail to lock securely and must be replaced promptly to prevent the window sash from falling.<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Aging rubber seals are a major cause of water leakage<\/td>\n<td colspan=\"1\" rowspan=\"1\">Silicone sealing strips are affected by UV exposure and thermal expansion\/contraction; they typically begin to crack within five to eight years. If not replaced in time, rainwater seeps into the wall along the gaps, leading to far higher repair costs later.<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Leakage repairs must first identify the exact source<\/td>\n<td colspan=\"1\" rowspan=\"1\">Mistaking external wall cracks for window-frame leakage (or vice versa) results in ineffective repairs and repeated charges. A professional inspection report is essential to avoid this problem.<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Repair costs vary widely; quotations must itemise parts and labour<\/td>\n<td colspan=\"1\" rowspan=\"1\">Market rates for hinge replacement range from HK$100 to over HK$300 per hinge. Seal replacement is charged by frame length. Owners should always request a fully itemised quotation and avoid \u201call-inclusive\u201d packages.<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Mandatory Window Inspection results determine repair necessity<\/td>\n<td colspan=\"1\" rowspan=\"1\">The Buildings Department\u2019s Mandatory Window Inspection Scheme requires buildings aged ten years or above to undergo regular inspections. Only reports issued by qualified registered personnel are legally accepted, helping avoid unnecessary works.<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Full window replacement is not always the most expensive option<\/td>\n<td colspan=\"1\" rowspan=\"1\">When the frame is severely corroded or multiple components fail simultaneously, the cumulative cost of partial repairs may exceed that of full replacement. A professional engineer should assess before deciding.<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">Only necessary repairs represent true cost savings<\/td>\n<td colspan=\"1\" rowspan=\"1\">Some contractors habitually bundle unnecessary waterproofing works. Choose companies that charge only for genuinely required repairs \u2014 EJW (Easy Job Solution Engineering Limited) follows the principle of transparent, itemised quoting.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<h2 id=\"common-failure-types\">Five Common Types of Aluminium Window Failures<\/h2>\n<p>On-site inspection experience shows that failures in Hong Kong residential aluminium windows can almost always be grouped into five categories. Understanding these helps owners make a preliminary assessment before contacting a repair company and enables them to spot whether unnecessary works are being suggested during quotation.<\/p>\n<p>The first type is <strong>loose or damaged hinges<\/strong>. This is the most frequent complaint, especially in buildings over fifteen years old. Hinges bear the full weight of the sash; after metal fatigue, screw holes enlarge, causing the sash to sag or fail to close properly.<\/p>\n<p>The second type is <strong>aging and cracking rubber seals<\/strong>. Once the sealing strips lose elasticity, rainwater and wind noise enter the interior.<\/p>\n<p>The third type is <strong>deformed frames or tracks<\/strong>. Although aluminium alloy resists corrosion, prolonged thermal expansion and contraction can bend the tracks, making the sash difficult to operate.<\/p>\n<p>The fourth type is <strong>damaged latches or handles<\/strong>. Although seemingly minor, if the latch cannot engage correctly there is a real safety risk of the sash being blown open during typhoons.<\/p>\n<p>The fifth type is <strong>water seepage at the frame-to-wall joint<\/strong>. This is frequently not merely a seal issue but indicates failure of the external wall waterproofing layer as a whole.<\/p>\n<p>These five failure types sometimes occur together, yet contractors should never recommend full window replacement as a blanket solution. <strong>The correct approach is to evaluate the severity of each item individually<\/strong> before determining the repair scope. EJW\u2019s practice is for a Buildings Department-registered person to complete an independent inspection before issuing specific recommendations, ensuring owners pay only for necessary works.<\/p>\n<h2 id=\"hinge-replacement-cost\">Aluminium Window Hinge Replacement: Cost and Process Details<\/h2>\n<p><strong>Aluminium window hinge replacement<\/strong> is the most frequent repair project for residential aluminium windows in Hong Kong. Hinge lifespan is influenced by three main factors: frequency of use, sash weight and metal quality. Under normal domestic conditions, hinges typically last ten to fifteen years; in kitchens and bathrooms, higher humidity may shorten this to around eight years.<\/p>\n<h3>Hinge Replacement Process<\/h3>\n<p>The process includes removing the sash, dismantling the old hinges, cleaning the installation area, fitting new hinges, refixing the sash and testing opening, closing and latching functions. The work usually takes thirty minutes to one hour depending on the number of windows. If old screw holes have enlarged, additional time is required to fill and reposition them.<\/p>\n<p>Some contractors recommend extra seal replacement or waterproofing coating while changing hinges. Owners should insist on a clear explanation of the necessity of each additional item rather than accepting an all-in-one package.<\/p>\n<h3>Hinge Replacement Cost Range<\/h3>\n<p>Market quotations for <strong>aluminium window hinge replacement<\/strong> vary according to part quality and contractor. Typical rates are: standard hinges (including labour) HK$220\u2013HK$500 each; heavy-duty or original-specification models HK$300\u2013HK$800 each. Hole filling or special installation incurs additional labour charges of HK$200\u2013HK$400 per hour. For a standard residential unit with six to eight windows, total hinge replacement costs generally range from HK$1,500 to HK$4,000.<\/p>\n<p><strong>A common mistake is for owners to request full window replacement immediately upon noticing a sagging sash. In reality, over ninety per cent of sagging problems can be resolved simply by replacing the hinges. On-site assessment by qualified engineering personnel is the most direct way to avoid unnecessary expenditure.<\/strong><br \/>\n<strong>Tip:<\/strong> Always request the specification of the new hinges. Using non-compliant hinges may allow short-term normal operation but will accelerate long-term wear on both sash and frame.<\/p>\n<h2 id=\"seal-replacement-cost\">Aluminium Window Rubber Seal Replacement: When Replacement is Necessary<\/h2>\n<p>The rubber seals (weatherstripping) of aluminium windows form the first line of defence against rainwater, noise and wind-blown sand. Hong Kong\u2019s hot, humid climate and strong typhoon winds cause seals to deteriorate far faster than in temperate regions. Industry experience shows that most residential seals begin to harden, crack, detach or lose elasticity within five to eight years of installation.<\/p>\n<h3>How to Assess Seal Aging<\/h3>\n<p>Owners can perform a preliminary check: press the seal lightly with a finger \u2014 if it feels hard and brittle instead of soft and elastic, it has aged; look for visible cracks or partial detachment; during rain, check whether water appears at the bottom or sides of the frame; persistent wind noise after closing the window also indicates seal failure.<\/p>\n<p>Note that aging does not always require full replacement. Localised detachment may be repaired locally, but if the entire seal has hardened, full replacement is the only effective solution.<\/p>\n<h3>Seal Replacement Cost<\/h3>\n<p><strong>Aluminium window rubber seal replacement<\/strong> is usually charged by frame perimeter or per window. Market rates are approximately HK$300\u2013HK$800 per window (including labour and materials); for a whole standard two-bedroom flat, HK$3,000\u2013HK$5,000. Special or custom seals are quoted separately. Although premium silicone seals cost slightly more, they typically last three to five years longer than standard grades, offering better long-term value.<\/p>\n<p><strong>Important detail:<\/strong> After replacement, allow at least twenty-four hours for the new seals to fully adhere. Avoid frequent opening and closing during this period, otherwise the seals may shift and compromise performance.<br \/>\n<strong>Tip:<\/strong> Replacing aging seals before a Mandatory Window Inspection helps pass the inspection and reduces the likelihood of being ordered to carry out larger-scale repairs. EJW inspection reports clearly state which seals must be replaced and which remain acceptable, avoiding unnecessary costs.<\/p>\n<h2 id=\"water-leakage-repair\"><img decoding=\"async\" style=\"width: 1024px; height: 1024px; object-fit: cover;\" src=\"https:\/\/www.hkejw.com\/wp-content\/uploads\/2026\/05\/Waterleakingaroundthewindow.webp\" alt=\"Water Leakage Illustration\" \/><\/h2>\n<p>&nbsp;<\/p>\n<h2>Aluminium Window Water Leakage Repair: Diagnosis Before Commencing Work<\/h2>\n<p>Aluminium window water leakage is one of the most common problems faced by Hong Kong owners, yet it is also the most frequently misdiagnosed. In many actual cases the root cause is external wall cracks or failure of the window-sill waterproofing layer rather than the aluminium window itself. Applying sealant directly to the window without proper diagnosis not only fails to solve the problem but may conceal more serious structural defects.<\/p>\n<h3>Three Main Sources of Leakage<\/h3>\n<p>Aluminium-window-related leakage generally originates from three locations: (1) the joint between window frame and wall \u2014 the most common, usually caused by aging silicone or inadequate original filling; (2) the seal between glass and frame \u2014 once the glass sealant ages, water enters directly; (3) blocked drainage holes at the bottom of the frame \u2014 water backs up into the interior.<\/p>\n<p>Accurate diagnosis requires a professional water-spray test performed zone by zone. This must be carried out by experienced personnel; owners should not attempt it themselves as improper technique may damage already weakened waterproofing layers.<\/p>\n<h3>Leakage Repair Cost Range<\/h3>\n<p><strong>Aluminium window water leakage repair<\/strong> costs vary significantly according to cause and severity. Localised re-sealing of frame joints costs HK$300\u2013HK$600; combined seal replacement and re-sealing usually HK$500\u2013HK$1,200; repairs involving external wall waterproofing may range from HK$3,000 to over HK$10,000 depending on affected area.<\/p>\n<p>When selecting a contractor, always choose one willing to issue a written diagnostic report before providing a quotation. Insistence on \u201cpay first, work later\u201d without detailed explanation is a clear warning sign.<\/p>\n<blockquote><p>\u201cThe biggest mistake in leakage repairs is commencing work before confirming the true source. Every ineffective repair merely adds another layer of concealment over the real problem.\u201d \u2014 Practical observation by the EJW engineering team<\/p><\/blockquote>\n<p>&nbsp;<\/p>\n<h2 id=\"cost-comparison\">Comparison Table of Various Repair Costs<\/h2>\n<p>The following table summarises fee ranges, applicable situations and expected outcomes for three common aluminium window repair approaches in the Hong Kong market.

Report fees vary by building size and number of windows; owners should obtain separate quotations from Buildings Department-registered inspection companies.<\/p>\n<h2 id=\"mandatory-inspection\">Mandatory Window Inspection Scheme and Its Relation to Repairs<\/h2>\n<p>Under Hong Kong\u2019s Buildings Ordinance (Chapter 123), the Buildings Department\u2019s Mandatory Window Inspection Scheme requires designated residential and commercial buildings aged ten years or above to engage qualified persons to inspect external windows periodically. The scheme\u2019s primary purpose is to prevent high-altitude falling-window accidents, not to generate business for repair companies. Understanding the scheme enables owners to judge which repairs are genuinely necessary.<\/p>\n<p>Only Buildings Department-recognised \u201cqualified persons\u201d (architects, engineers or surveyors) or their approved \u201cregistered contractors\u201d may carry out inspections and issue reports. Reports must follow the prescribed format; non-compliant or unqualified reports are not accepted.<\/p>\n<p>A frequent mistake is accepting an all-in-one \u201cinspection-plus-repair\u201d quotation without verifying the inspector\u2019s qualifications. Some companies dispatch unqualified workers for \u201cvisual checks\u201d and then propose extensive repairs to inflate charges. Such reports lack legal validity.<\/p>\n<p>EJW\u2019s inspection work is performed exclusively by <strong>Buildings Department-registered personnel<\/strong> and includes computerised detailed reports listing each window\u2019s condition rating, specific repair locations and priority order. This gives owners a clear, comprehensive picture and prevents inflated or duplicated charges.<\/p>\n<p><strong>Tip:<\/strong> Upon receiving a Mandatory Window Inspection notice, the Owners\u2019 Corporation should obtain quotations from at least three licensed companies and verify each qualified person\u2019s registration. The lowest price is not necessarily the best value; report quality and recommendation transparency matter most.<\/p>\n<h2 id=\"choosing-contractor\">How to Choose a Reliable Aluminium Window Repair Contractor<\/h2>\n<p>Selecting the right contractor is the most practical decision owners face. The Hong Kong market contains contractors of varying standards \u2014 some specialise in compliant Mandatory Window Inspection services while others attract customers with low prices and later add hidden charges. The following criteria are drawn from real-world experience.<\/p>\n<h3>Qualification Verification Comes First<\/h3>\n<p>Before accepting any quotation, request proof of Buildings Department registration or recognition. For Mandatory Window Inspection works, qualified person details can be checked in the public database on the Buildings Department website. Companies unable to provide this information should be avoided, regardless of price.<\/p>\n<p>Additionally, confirm that the contractor holds public liability insurance. Working at height carries inherent risks; insurance protects owners from potential legal liability in the event of accident or damage.<\/p>\n<h3>Requirements for Transparent Quotation<\/h3>\n<p>A trustworthy quotation must include: itemised fees for every repair item, specifications of parts used, project timeline and warranty terms (minimum one-year workmanship warranty). A contractor who offers only a \u201cbundled\u201d total price and refuses to itemise should be treated as a warning sign.<\/p>\n<p>The hallmark of a truly professional contractor is the willingness to charge only for necessary repairs and to state clearly in writing which items do not require work. <strong>Transparent quoting is not an optional extra \u2014 it is an owner\u2019s basic right.<\/strong> Choosing EJW, which explicitly commits to charging only for necessary repairs, is the most direct way to safeguard your interests.<\/p>\n<h2 id=\"faq\">Frequently Asked Questions<\/h2>\n<p>&nbsp;<\/p>\n<h3>How long does aluminium window repair usually take?<\/h3>\n<p>Partial repairs (hinge or seal replacement) on a typical residential unit can normally be completed within half a day to one full day, depending on the number of windows and problem severity. Full window replacement or larger waterproofing works may require one to three days. After completion, silicone sealant requires twenty-four to forty-eight hours to cure; windows should avoid heavy moisture exposure during this period.<\/p>\n<h3>How soon will hinges need replacing again?<\/h3>\n<p>When high-quality hinges are correctly installed by professional personnel, new hinges generally last ten to fifteen years. Insufficient hole filling, non-compliant parts or excessive sash weight can shorten lifespan to under five years. Annual cleaning and light lubrication significantly extend service life.<\/p>\n<h3>Who pays for the Mandatory Window Inspection?<\/h3>\n<p>Under Hong Kong law, inspection fees are borne by the owners. Where an Owners\u2019 Corporation exists, fees are usually recovered through management fees or special levies according to undivided shares. Individual flat owners who engage an inspector independently bear the full cost themselves. The Buildings Department operates subsidy schemes that may provide partial assistance to eligible owners of older buildings; details are available directly from the Department.<\/p>\n<h3>Must the entire window be replaced if there is leakage?<\/h3>\n<p>Not necessarily. Most leakage problems can be resolved by partial repairs such as re-sealing, seal replacement or clearing drainage holes. Full replacement is required only when the frame itself is structurally damaged (severe corrosion or deformation) or multiple components have failed simultaneously. A water-spray test by qualified personnel should always be carried out first to confirm the exact source before any works commence.<\/p>\n<h3>How can I tell if a quotation is reasonable?<\/h3>\n<p>A reasonable quotation itemises both parts and labour costs and states the brand or specification of every component. Obtain quotations from at least three licensed companies for comparison. A quotation significantly below the market average may indicate lower-quality parts or a shortened warranty. Lowest price does not always equal best value \u2014 quality of workmanship and warranty protection are equally important.<\/p>\n<h3>How much time is allowed to complete repairs after receiving an inspection notice?<\/h3>\n<p>The Buildings Department generally allows three to six months (depending on the specific notice) to complete inspection and any required repairs. Failure to meet the deadline may result in the Department engaging a contractor on the owners\u2019 behalf and recovering costs \u2014 usually at a higher rate than market self-engagement. Prompt action upon receiving the notice is therefore essential.<\/p>\n<p>If you have previously handled aluminium window repairs or Mandatory Window Inspection, we welcome you to share your experiences to benefit other owners.<\/p>\n<h2 id=\"references\">References<\/h2>\n<p>&nbsp;<\/p>\n<ul>\n<li><a href=\"https:\/\/www.buildingmgmt.gov.hk\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Buildings Department Building Management Information \u2014 official requirements for the Mandatory Window Inspection Scheme and registered personnel database<\/a><\/li>\n<li><a href=\"https:\/\/www.gov.hk\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Hong Kong Government One-Stop Portal \u2014 Buildings Ordinance (Chapter 123) and owner responsibilities<\/a><\/li>\n<li><a href=\"https:\/\/www.hkust.edu.hk\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Hong Kong University of Science and Technology \u2014 research on the effects of Hong Kong\u2019s climate on external wall and window material aging<\/a><\/li>\n<\/ul>\n[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"<p>[vc_row type=&#8221;in_container&#8221; full_screen_row_position=&#8221;middle&#8221; column_margin=&#8221;default&#8221; column_direction=&#8221;default&#8221; column_direction_tablet=&#8221;default&#8221; column_direction_phone=&#8221;default&#8221; scene_position=&#8221;center&#8221; text_color=&#8221;dark&#8221; text_align=&#8221;left&#8221; row_border_radius=&#8221;none&#8221; row_border_radius_applies=&#8221;bg&#8221; row_position_desktop=&#8221;default&#8221; row_position_tablet=&#8221;inherit&#8221; row_position_phone=&#8221;inherit&#8221; overflow=&#8221;visible&#8221; overlay_strength=&#8221;0.3&#8243; gradient_direction=&#8221;left_to_right&#8221; shape_divider_position=&#8221;bottom&#8221; bg_image_animation=&#8221;none&#8221;][vc_column column_padding=&#8221;no-extra-padding&#8221; column_padding_tablet=&#8221;inherit&#8221; column_padding_phone=&#8221;inherit&#8221; column_padding_position=&#8221;all&#8221; flex_gap_desktop=&#8221;10px&#8221; column_element_direction_desktop=&#8221;default&#8221; column_element_spacing=&#8221;default&#8221; desktop_text_alignment=&#8221;default&#8221; tablet_text_alignment=&#8221;default&#8221; phone_text_alignment=&#8221;default&#8221;&#8230;<\/p>\n","protected":false},"author":1,"featured_media":3247,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"rs_blank_template":"","rs_page_bg_color":"","slide_template_v7":"","footnotes":""},"categories":[30],"tags":[38,37,36,40,39],"class_list":{"0":"post-3300","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-am-information","8":"tag-38","9":"tag-37","10":"tag-36","11":"tag-40","12":"tag-39"},"_links":{"self":[{"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/posts\/3300","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/comments?post=3300"}],"version-history":[{"count":16,"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/posts\/3300\/revisions"}],"predecessor-version":[{"id":3324,"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/posts\/3300\/revisions\/3324"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/media\/3247"}],"wp:attachment":[{"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/media?parent=3300"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/categories?post=3300"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hkejw.com\/en\/wp-json\/wp\/v2\/tags?post=3300"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
