"TwinGlaze is a model of what good service should be, from the initial visit from Anita and prompt quotation to the final fit out today by Matt and his team. Quality and price of the product exceeded expectations and Matt and his team displayed professionalism and a thorough understanding of the job leaving the site spotless. We are very happy with end result and would highly recommend TwinGlaze to anyone contemplating retrofitting double glazing to their home."

 "We emailed a few companies of which most ignored our inquiry. Anita was quick and professional to respond with a very reasonable quote. Matt and his team were also top notch. Friendly, efficient, on time, all round 10/10. You can't go wrong with TwinGlaze. Thanks team!"

"Like others who have left a review, Anita was extremely efficient in responding to my first approach (contrary to other companies who didn't bother responding). After much research I decided that TwinGlaze had "real" double glazing, rather than magnetic stick-ons or non-glass options. TwinGlaze's price was also very fair and cheaper than the pretenders. We had difficult second-storey access for installation, and Matt and Duncan did a fantastic job. We had the job done to minimise sound from the street, and we are highly delighted with the outcome. I can't recommend TwinGlaze highly enough"

"Being northern Europeans we wanted our house properly insulated against the winter cold. What really impressed me about this company was the care taken to make sure that the intended outcome was reached. This house of freezing night time draughts is now far more comfortable. Until this week we needed the heater on to work in the study, but now I am sending this message in perfect comfort on a chilly day. We will be having them back to do the rest next year"

"I live on the 12th floor facing south, east & west, in an large open plan apartment. There is a lot of glass, a source of heat loss. When it was windy, you could hear the wind howl. Since the double glazing, my apartment is much more insulated & you can't hear the wind. Visitors have commented on how insulated the place feels. The service from Twinglaze couldn't have been better. I had faith in Daryl from our first meeting. The under carpet heating has been turned off and once the temperature warms up, it stays due to the double glazing. I couldn't speak more highly of Twinglaze."

"I have used Twinglaze twice. On both occasions they have been fantastic. Their product is very good, and does what they claim it does, their service exceptional. Daryl Gillum managed the second job which involved fitting double glazing into existing old windows and doors and into a new custom made door. He has coordinated different suppliers, provided hands on "problem solving" and support and, at all times, has been an absolute pleasure to deal with. I can't recommend Daryl and Twinglaze highly enough. I am happy to provide references. Gavin Watkins, Redfern, Sydney"

"TwinGlaze retrofitted double glazing to our house in the hills out of Melbourne. The cost was a fraction of the price quoted by others to replace the existing windows and the result was excellent. Quoting measuring and fitting were all done promptly and efficiently. Communication at all times was excellent. Good product, excellent service at a very fair price. Couldn’t be happier."
