A Local Selwyn Team, Based in Lincoln

Cold Canterbury winters, condensation, and road noise affect homes across Lincoln, Rolleston, Prebbleton, Springston, and Tai Tapu — in newer subdivisions and established properties alike. Retrofit double glazing lets you keep your existing joinery while fixing the parts that actually cause discomfort: single-pane glass. GlacierLite assesses your frames honestly before recommending retrofit, so you know it’s the right option for your home before you commit.

Retrofit Double Glazing Cost for Selwyn Homes

Pricing depends on window size, frame condition, glass specification, and site access. As a general guide for Selwyn homes:

  • Aluminium retrofit: $400–$850 per window
  • Timber retrofit: $800–$1,200 per window
  • Whole-home retrofit: commonly $5,000–$25,000+

For a full regional cost breakdown, see our double glazing cost guide.

Is Your Selwyn Home a Good Candidate for Retrofit?

Retrofit keeps your existing frame and replaces the glass with an insulated double-glazed unit. It works well for many Selwyn properties where the joinery is still sound, but it isn’t always the right fit.

Good candidates

  • Existing aluminium frames in solid condition
  • Sound timber windows
  • Homes with condensation or cold rooms
  • Character homes where keeping original joinery matters

May need replacement instead

  • Rotten or badly warped timber
  • Frames out of square or damaged
  • Windows too shallow for the right glass unit
  • Projects needing a full weather-tightness upgrade

Retrofit Options for Aluminium and Timber Windows

Aluminium Windows

Many aluminium windows can be retrofitted if the frames are still strong and suitable, improving warmth and condensation control without replacing the entire window system.

Timber Windows

Sound timber windows can often be upgraded while preserving the original character of the home. We check timber condition carefully before recommending retrofit.
