I had Thermotek windows+doors installed recently+they’re fantastic! It was a difficult job requiring a crane for large upstairs window+doors but all went very smoothly+has made a huge difference in noise reduction+increasing thermal efficiency. The Thermotek team were great to deal with,very helpful+professional-I highly recommend them.

We couldn’t be any happier with the workmanship, reliability and friendliness from the team at Thermotek (even our dog was receiving pats!). We will certainly be recommending Thermotek to family and friends.

Had 5x DG windows (tilt & turn) installed upstairs and had an external laundry door replaced with a DG door. Overall a very good experience, happy to recommend or use again.Good: Great value for $$. Great glazing options and was able to find the perfect solution for our needs. They were really helpful getting the design right. Installation process was very good. They even included insulation/foam around the window.Not so good: There was significant delays – partly due to the pandemic – with the glazing. There is a lack of colour options.

Thankfully our issues have been resolved!We had such a brilliant experience with Thermotek! Michael came to my Mums house and went through everything so carefully to ensure she got exactly what she wanted. The windows and doors are incredible quality and have absolutely reduced heating/cooling costs and drastically reduced noise inside the house. Our experience was so good that we’re now having them installed in our own home! Absolutely recommend!!)
