We are very pleased with the installation and look forward to being able to use our balcony with less wind. A big thank you to DGA for being such a good project manager and arranging it to run so smoothly.

We asked DGA to replace our old sliding bedroom window specifically for noise insulation. Once we experienced our new “whisper glass” awning window, we couldn’t stop at one room. Not only did it stop the noise, it also kept the bedroom much cooler. We kept getting DGA back to do other windows we were that impressed with the quality of the installation and the windows. Chief installer Jarrad and Robert are true craftsmen, with such attention to detail. There was no damage to our walls, they worked cleanly and quietly and were very professional to deal with. They also came back to replace our old back sliding security screen door with Invisimesh including pet door. Again, such a brilliant job. Will, who manages the jobs, was so attentive and always kept us informed all the way along the project. We felt the quotations were fair, given the quality of the work and the Australian materials.

I just wanted to let you know how impressed I have been with my project manager Simon .

I recently had a small job completed . Simon kept me informed regularly & his emails & calls were the perfect balance of professionalism & friendliness . The job was completed efficiently but required follow up & Simon completed this himself to get the job done keeping me in touch with the progress at all times .

He is an outstanding example of how the service industry should work but rarely does . Please pass my compliments to Simon & thank him for a job well done . He is a great asset to you .


I would like to take this opportunity to compliment the efficiency of the serviceman in his job. Added to this he arrived when he said he would (something that does not always happen these days). Overall he should be commended for the quality of his workmanship. Thanks again.

I have to admit that I’ve been impressed by how professional you’ve been throughout the quote process, which is more than I can say for many of the other companies I’ve dealt with so far!

DGA have been purchasing glass from us for the last 6 years.

Over the time we have supplied many large projects with a variety of glass and make ups. From the basic toughened and laminate to complex IGU make ups with custom laminate and articulated ball joints connected to spider fitting’s for many projects.

During this time DGA have been professional in their dealing with us as a priority customer. They have maintained an excellent payment record keeping well within their trading terms whilst at the same time growing their business to one of our major customers.
