Retrofit or Full Replacement: Which Option Suits Your Home?

Both pathways can improve comfort, but the right choice depends on your existing frames. Retrofit double glazing upgrades your current frames by replacing the glass unit, keeping disruption to a minimum. Full replacement removes the entire frame and joinery and suits homes where frames are damaged, poorly sealed, or failing to meet modern weathertightness standards. Wellington's coastal winds and wet winters mean poorly sealed windows can allow moisture ingress, leading to condensation, mould, and heat loss. Aluminium frames are a practical choice: they do not warp, do not require painting, and their dimensional stability makes future glass replacement straightforward. Visit the double-glazed windows and doors page for available glazing options.

How Much Does Window Replacement Cost in Wellington?

Costs vary depending on scope, size, and glazing specification. Retrofit double glazing typically ranges from around $450 to $800 per m², while full window replacement commonly sits around $800 to $1,600 per m². For a standard Wellington home, a full replacement project may range from several thousand dollars for a single window up to $20,000 or more for whole-house joinery. Complete Aluminium Maintenance Ltd offers free, no-obligation quotes to help you plan with confidence.

Do You Need Building Consent for Window Replacement in NZ?

Most like-for-like window replacement does not require building consent. Under Schedule 1 of the Building Act 2004, window replacement in existing dwellings of up to two storeys is generally exempt, provided the original installation met durability requirements and the replacement is in the same position. Consent may be required if the window has failed within 15 years or if opening sizes are being changed structurally. Always confirm specific requirements with your local council. The team at Complete Aluminium Maintenance Ltd can help guide you through what applies to your job.

Aluminium vs uPVC: Choosing the Right Frame for Your Project


Aluminium is the right choice for most Wellington and Hutt Valley projects. It is durable, low maintenance, corrosion resistant, UV resistant, and 100% recyclable, with a lifespan of 30 to 40 or more years. For Wellington's exposed coastal and wind-prone sites, aluminium is lightweight yet robust.

uPVC offers strong thermal insulation but has a limited range of shapes and a bulkier profile. Modern thermally broken aluminium is now competitive on energy performance without the aesthetic compromise. For homes with existing aluminium joinery, like-for-like replacement is typically the most practical and visually consistent solution.

Do You Need Building Consent to Replace Windows in Wellington?


In most cases, replacing windows in an existing Wellington home does not require building consent. Work on a window or exterior doorway in an existing dwelling of not more than two storeys is generally exempt. There is an important exception: if a window installed within the last 15 years has failed, a building consent is required. Where consent is not needed, work must still comply with the Building Code. If you are unsure, the team can help you work through the question before any work begins.

Frequently Asked Questions About Window Replacement in Wellington

  • What Is the Difference Between Retrofit and Full Frame Window Replacement?

    Retrofit fits new glazing or a sash into an existing frame. Full frame replacement removes and replaces the entire frame, which may be needed when frames are corroded or when upgrading to double glazing requires a deeper profile. The team will advise at assessment.

  • Is Aluminium Window Replacement Suitable for Older Wellington Homes?

    Yes. Many aluminium windows installed in the 1970s are now nearing the end of their life. Replacing them with new aluminium joinery can improve weathertightness, thermal performance, and security without significantly changing a property's external character.

  • How Long Does a Window Replacement Project Typically Take?

    Most residential jobs are completed in a single day. Lead time varies based on product availability and scheduling. Contact the team for a realistic timeframe.

  • Can You Replace Windows in a Multi-Storey or Commercial Building?

    Yes. Complete Aluminium Maintenance Ltd specialises in high-rise work including abseiling, and can schedule commercial replacements to minimise disruption to occupants.
