Two-colour uPVC windows for Christchurch Home Transformation
The Renovation Decision That Changed Everything
When Serena started thinking seriously about renovating her modern brick home in Christchurch, she was at a crossroads: move and buy something newer, or invest properly in the home she already had. Renovation won, and replacing the single-glazed windows was at the very top of the list.
What followed was a full upgrade to uPVC joinery from NK Windows, transforming not only the warmth and quietness of the house, but its appearance and overall feel too.

The Challenge: Making an Existing Home Worth Staying In
Once Serena decided to renovate, she wanted the improvements to make a genuine difference rather than simply refresh the surface. The original single-glazed windows had to go. At the time, uPVC windows were still relatively unfamiliar to Serena, which made understanding the different options an important part of the decision.
Warm, comfortable, secure and stylish double-glazing – with white frames on the inside and black on the outside – has added value and personality to this Christchurch home
The Solution: A Local Team and a Different Kind of Window
Serena was keen to find out more about uPVC and was drawn to NK Windows because they were local, knowledgeable and able to clearly explain the benefits of the system. A visit to the NK Windows showroom helped make the decision easier. Among the aspects of NK that appealed to Serena were:
Clean designs that would enhance her modern home and simple aesthetic
Double glazing for noise reduction and thermal performance
Low-maintenance uPVC frames, ideal for long-term durability
The ability to have different colour finishes on the inside and outside of the home
Locally made products backed by a highly experienced Christchurch team
Serena was able to see the products first-hand, talk through the different options and ask questions before committing. She found the whole process straightforward from beginning to end, and that same experience continued through installation. Serena was comfortable leaving the installation team to get on with the work, knowing she would be kept informed throughout.
The Result: Warmer, Quieter, Safer — and a Completely Different Look
“Love the quietness, warmth, safety and the look!”
The impact of the new windows was immediate.
For Serena, the improvement wasn’t limited to one thing. The house became quieter and warmer, felt more secure, and gained a much sharper, more contemporary appearance.
One of her favourite design features is the ability to have a different frame colour inside and outside, allowing the joinery to work with both the exterior of the brick house and the interior décor.

That flexibility helped make the new windows feel like an integral part of the renovation rather than simply a replacement for what had been there before.

The Outcome The Best Decision in the Renovation
Looking back, Serena has no hesitation about which part of the project made the biggest difference.
“Easily the best thing I did in the renovation. It changed the look and feel of the place.”
The windows have also become one of the features other people notice most, with Serena regularly receiving comments about them. Her experience has left her firmly convinced of the benefits of uPVC. “I love the windows and would definitely go for uPVC again over aluminium.”
Choosing a Christchurch-based company was another important part of the experience, giving Serena the reassurance of dealing with a local team throughout the process. And she hasn’t just said she would recommend NK Windows — she already has. “My work colleague used them last year for new windows in her home.”
