Service Overview
When old aluminium windows have deformed frames, seepage at several points or fail to open and close, and repair only treats the symptoms, replacing them with new aluminium windows is the more thorough solution. Whether you need a whole-flat replacement or to replace only the damaged or leaking windows, Amgen can handle it — offering a one-stop service from measuring and removal to custom fabrication and waterproof sealing.
The process is clear: on-site measuring and quotation → custom fabrication → removal of old windows → installation of new aluminium windows (bracket fixing and level alignment) → silicone waterproofing at the frame joints → water-test acceptance. A licensed technician sees it through, with a waterproofing warranty.
For specifications, you can choose 40- or 50-series profiles according to floor level and wind exposure, and single-pane, insulated or Low-E glass. A full aluminium window replacement is alteration work involving the wall structure, classified as Class II minor works and subject to Class II minor works declaration; Amgen (MWC 316/2021) can handle the declaration documents to keep the works compliant.

Frequently Asked Questions
How much does aluminium window replacement cost?
Replacement is generally priced per square foot, depending on the profile series (40/50), glass type (single / insulated / Low-E), the number of windows, and whether scaffolding is needed. After on-site measuring, the technician provides a transparent quote with no hidden charges.
Can I replace just a few windows instead of the whole flat?
Yes. Amgen handles both whole-flat and partial replacement. If only certain windows are damaged or leaking, you can replace just those, priced by window count and size — there is no need to replace the whole flat.
What is the window replacement process?
The process is: on-site measuring and quotation → custom fabrication → removal of old windows → installation of new aluminium windows (bracket fixing and level alignment) → silicone waterproofing at the frame joints → water-test acceptance, handled throughout by a licensed technician.
Can iron windows be replaced with aluminium?
Yes. Oxidised old iron windows are commonly replaced with aluminium; Amgen removes the old iron windows, custom-makes and installs new aluminium windows and re-does the waterproofing. For public housing, iron window replacement should first be checked with the Housing Department / estate office.
Does a full aluminium window replacement need to be declared to the Buildings Department?
Yes. A full aluminium window replacement is alteration work involving the wall structure, classified as Class II minor works and subject to Class II minor works declaration. Amgen is a Buildings Department Registered Minor Works Contractor (MWC 316/2021) and can handle the commencement and completion declaration documents.
