Winplex were fantastic. From the get-go, when I spoke with John, he came around and consulted with us on our best options, helped us make decisions, and when it came time to install, not long after, the team were in and out quickly. The product is excellent, and the team was super friendly and reliable.

We just had 6 windows, including two very large picture windows plus a set of french doors installed. From the get-go, Winplex was a standout choice for our renovation needs. Starting with John who provided us with a thorough initial quote, the journey was nothing short of professional and reassuring. The consistent stream of communication ensured we were kept in the loop at every step. I can't speak highly enough of the installation crew. The team, comprising Warren, Stefan, Seb, Melvin, and others, brought with them an air of efficiency and friendliness that was refreshing to see. Their speed did not compromise the quality, as they were thorough to the finest detail and kept the workspace clean, even disposing of the old aluminium frames. The craftsmanship of the installed windows is evident as they look nothing less than stunning. Not only has the appearance of our home been elevated, but the sound insulation has improved dramatically. A heartfelt thank you to the entire Winplex team for their hard work and dedication. It is clear that customer satisfaction is at the heart of their service – a trait that is often promised but not always delivered.

Winplex was recommended to me by a friend. I called on Monday and Adi came to do a quote for me to replace all the windows and door from my house. The quality of their product is great (as confirmed by a friend of mine who does window installation in Europe). Adi is lovely, honest, knowledgeable and very helpful. He was so patient with answering all my questions. I did not feel the need to think it over at all. Thank you Adi and I’m looking forward to my new windows in the new year.

Just purchased 7 windows/doors from Winplex and couldn't be happier with the results. The installation team were courteous, helpful, friendly and extremely efficient (also going the extra yard). The end result was a fine job with an eye for detail. we'll certainly be using them again. Can't recommend the company enough.

Great team from start to finish. We are very pleased with our fixed pane window and slide door we had installed recently. Professional team and no hard sell like some other companies I tried. Will certainly be using them again for the rest of our house :)

Over the past 12 months we have had Winplex supply and install 2 big invisifold doors, a tilt / turn window and a fixed picture window. Really high quality solid products, very well made. Special mention to the install team who were quick, clean and efficient. Attention to detail from both the manufacturing team and the install team was outstanding. Highly recommended.
