I cannot thank Martin and his team at NK Windows enough for the exemplar 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 1950's home. For anyone wanting a fast, efficient and professional service, I would recommend NK Windows as your go to company.

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 means 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.

Zero moisture

...Now that we have had many months of all weather, I can say categorically that we have had zero, absolutely zero moisture on the inside of our new uPVC windows. They always feel warm and dry. It has definitely improved the temperature and comfort in the house, even in the room furthest away from the heatpump. If I have one regret, it's that we couldn't afford to exchange the entire houselot of windows and ranchsliders: uPVC is clearly hugely superior to the aluminium that's mysteriously still being used NZ-wide. If you have a choice, if you can afford to build, you'd be crazy to choose aluminium. Tania was incredibly patient working with us through several quotes to see just how much we could afford to do. Installation day went off without a hitch. Couldn't recommend these windows, and this company more.

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 accomodating. The crew who installed the windows and doors was professional and the work they did was spotless. The after-care 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.

Professionalism and knowledge

We just had 8 windows and a new door installed by NK windows, and immediately notice the increased warmth and decreased noise inside the house. The windows look good and the opening tilt and swing hardware works 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, great attention to detail. PVC 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 install as well so it was easy, and we knew it was done right for the window requirements.
