Testimonials

I cannot thank Martin and his team at NK Windows enough for the exemplary service they have provided. Right from the beginning, NK Windows showed exceptional professionalism through ongoing communication of updates, scheduling of work, and guidance on how to prepare for installation.

The work was completed well within the time frame provided, and the contractors were so friendly. They cleaned the windows so well at the end; I questioned whether the glass was installed! The windows look absolutely amazing and have transformed and modernised my 1950s home. For anyone wanting a fast, efficient, and professional service, I would recommend NK Windows as your go-to company.

Roslyn

We had such an amazing, stress-free experience with NK windows. Tani is wonderful and a real asset to the firm. She explained everything so clearly and at great details and was super flexible when we wanted to make changes to the plan. She oversaw the project and was always available, always super helpful and accommodating.

The crew who installed the windows and doors were professional, and the work they did was spotless. The aftercare was also top-notch. The product itself is just superior and really transformed our house. Overall, we could not be happier with the service we got from NK, and we cannot recommend them highly enough.

Kat

We just had 8 windows and a new door installed by NK Windows, and immediately noticed the increased warmth and decreased noise inside the house. The windows look good, and the opening tilt and swing hardware work really well. Particularly impressed by the professionalism and knowledge of the people we dealt with from the initial quote to the detailed measure and the final installation.

The install guys were happy to answer all my questions and kept everything very tidy while installing as well, with great attention to detail. uPVC windows are the way to go, and we picked NK windows because we liked that they have their own NZ-based factory to make sure windows are made for NZ building requirements and that they complete the installation as well so it was easy, and we knew it was done right for the window requirements.

Alicia

Can highly recommend NK Windows to anyone who wants high-performance glazing on their house. Tani and the team were a pleasure to deal with and accommodated all our requests. Easy and professional install, thanks again!

Elena & Alex

We had an excellent experience with NK Windows, from Tani doing the quote to the final tweaks. They were very accommodating, and the install guys did an excellent job. Feels like a new house; would highly recommend the team to everybody.

Wayne

Our immediate thoughts were 'our house no longer feels like it's leaking heat.' Exceptional products that significantly outperform our 15-year-old double-glazed aluminium windows. No more condensation. Tilt & turn windows and doors mean we can securely ventilate and no longer run the risk of kids hitting their heads on an open window! I suggest you have a close look at glass options to reduce summer overheating we opted for Performatech206 on north and west faces. Standard Low E & Argon on all other windows.

Phil

We want to say a big THANK YOU to all involved with installing our new windows and doors, from the quotation team over the production team to the installation team. All did an exceptional job, and the result is stunning. We really enjoy warmth and a lot more of quiet time from all the road noise on State Highway 1.

Steffen

Fantastic staff and product. Everyone we dealt with was knowledgeable, helpful, and genuine. There were some unavoidable delays with our project, but the communication was fantastic throughout. The price wasn't much above replacing with aluminium, and the performance of the UPVC is far superior. The house was instantly quieter, and it's noticeably warmer, with no more condensation.

Rachel

Just had NK come out and quote for our windows and doors and well-itemised and understandable. And quite surprisingly less than what I thought it would be. Just a little bit more than retrofit which I know would be useless with our old, warped wood. After doing so much research NK windows are definitely what I would go for. We are now working out which windows to do first.
