How To Get Started With Your Upgrade
Frequently Asked Questions
Do I need a Council Building Consent to replace my windows?
In most cases in Christchurch, replacing existing windows with new ones of the same size does not require a building consent under Schedule 1 of the New Zealand Building Act. However, if we are widening existing openings, installing massive architectural stacker doors, or altering structural lintels, a consent may be required. Because we are Master Builders, we handle the entire engineering, drafting, and council application process for you if required.
Can we stay in the house during the window installation?
Absolutely. We work systematically room-by-room to minimize disruption to your daily life. We completely remove, install, flash, and weatherproof each window opening on the same day, ensuring your home is never left open or exposed to the elements overnight.
What happens if you find rotten timber framing around the old windows?
This is exactly why homeowners choose us over standard glazing companies. If we uncover historic leaks, degraded insulation, or rotten framing timber upon removing your old windows, our qualified builders fix it immediately on-site. We treat the structural issue properly, re-flash it to modern code, and ensure your home is completely airtight before the new window goes in.
How long does a typical full-home window replacement take?
For a standard 3 to 4-bedroom home in Canterbury, the physical on-site installation usually takes between 3 to 5 working days. We pride ourselves on working efficiently and leaving your home spotless at the end of every single working day.
Engineered For Performance. Backed By Registered Master Builders.
Because we manage the complete process—from initial laser measurements to final flashing inspections—you receive a structurally sound installation that fully complies with modern New Zealand Building Code standards. Enjoy lower energy bills, a healthier living space, and total peace of mind.
