“Super super company, cannot thank Zach and the team enough, we are a 24 hour Gym and had a security issue with our door and alarm system which needed a complete replacement door frame, door and new magnetic lock alarm system, the price was very reasonable, the work was carried out to a phenomenally high standard, the work was clean, tidy and exceptional. The service was top notch and the clean up afterwards was showroom quality, efficient service and very personable and would highly highly recommend these guys. There simply is not enough words or superlatives to say how great these guys and look no further”
“Amazing service and professionalism from Zach and the team. He was able to fix our shop door the same day we called. Thank you!”
“I had an unexpected emergency where my door was damaged, I called NZR windows and doors they were around within an hour and completed the repairs at a great price. I would highly recommend.”
“I had an a bit of an emergency, my bifold doors had badly sagged over time and eventually came off the runner when opening them and I just managed to close them but without locking. Zach came the following day to inspect them and immediately got on with removing all the glass units realigning the hinges and glass within the frame refitted runners, it was a tricky job but end result was superb, better than when they were first installed. He was very professional and was a fair price for the job 👍👍”
“Excellent service. He arrived quickly, was very helpful and friendly, and worked efficiently to get the door fixed. He clearly knew what he was doing and made a stressful situation much easier. Would definitely recommend his service.”
“On a Good Friday, of all days, my window decided not to close! I called NZR and spoke with Zach, and he saved the day! He came and fixed it for us within a few hrs of first contact! Great service and workmanship, and lovely guys too! Thanks for saving the day 😊”
