Windows & Joinery (Retrofit & Replacement)

Why Choose Us for Your Windows & Joinery (Retrofit & Replacement)?

Our team brings years of experience with windows & joinery

Warmer, quieter homes

Retrofit double glazing improves thermal performance and reduces noise/condensation.

Right method for your frames

We advise when retrofit IGUs suit and when a full replacement makes more sense.

Detailing follows NZ guidance for replacing/retrofitting windows in existing openings.

Careful sealing, trims and reveals for a tidy look inside and out. (Background: BRANZ guidance discusses fixings/reveals.)
