Our Testimoials

What our clients say

Double glazed doors are simply magic and have made a real difference in significantly reducing the noise outside. I sleep better and feel more relaxed! Also, I want to commend Christoffel's professionalism in the installation of our doors. The process was 100% professional from when he came to our home to confirm the quote to the actual installation, which was clean and precise. I would have no hesitation to recommend your business to others considering double glazed windows and doors.


It was quite a job to source this brilliant and quality product. The information and advice I received from Christoffel from the beginning was great. Knowing exactly when production would be completed and installation date arranged was a plus for me. It is a pleasure to have someone who knew what they were talking about. The quality of work was amazing, but consideration and thoughtfulness within my home was very much appreciated. The level of train noise has been reduced to a minimum.


Wonderful slump glass door! We receive many positive comments about it! Our house is now complete with double glazing and keeping us warm this winter. So, thank Marc, Mr and Mrs Christoffel and yourself for the service over the years.

Vicki and Steven

All went well with the installation of our windows and doors and we are very happy with them. Our sound problem has improved at least 80%. Christoffel did a great job on the installation. We're appreciative of your work.
