Service Overview
After years of use, oxidised hinges, loose handles, hardened and contracted silicone rubber sealant strips, and window-edge seepage are all common problems in Hong Kong's humid, salty environment. Most do not require replacing the whole window — targeted repair is often faster and more economical. Amgen offers one-stop aluminium window repair, with a licensed technician diagnosing on site and treating the exact cause.
Common repairs include replacing oxidised hinges, replacing loose or broken handles, replacing hardened and contracted silicone rubber sealant strips, re-applying silicone to waterproof the frame joints, and replacing broken glass. The technician first judges whether to repair or replace, avoiding unnecessary costs.
Amgen uses Amgen-brand 304 stainless steel hinges, tested through 50,000 open-close cycles, lasting 30 years or more, and compliant with SS212:1998, the Hong Kong Housing Department and QB/T3888 standards. Most repairs need no scaffolding and can be handled by removing the sash indoors — saving time and cost; works are carried out by our licensed minor-works contractor (MWC 316/2021).

Frequently Asked Questions
How much does aluminium window repair cost?
It depends on the repair items and the number of windows. Hinge, handle and sealant-strip replacement and silicone waterproofing each have a starting price; after an on-site diagnosis the technician provides an itemised, transparent quote with no hidden charges. Targeted repair usually costs far less than a full window replacement.
Does aluminium window repair need scaffolding?
Most repairs — such as replacing hinges, handles or sealant strips, or applying silicone indoors — can be handled by removing the sash indoors, with no scaffolding needed. Scaffolding is only required for large-scale external wall waterproofing or high-level exterior work, which the technician will explain in advance.
If a hinge is broken, must I replace the whole window?
Not necessarily. If the frame is structurally sound, replacing just the oxidised hinge is enough and costs far less than a replacement. Amgen uses Amgen-brand 304 stainless steel hinges lasting 30 years or more; only when the frame is deformed or multiple parts have failed should a full replacement be considered.
Is there a warranty on repairs?
Yes. Amgen provides a warranty on repair items, with the period and scope stated on the quotation. Works are carried out by our licensed minor-works contractor (MWC 316/2021), so quality is assured.
