Phillip Weston Jeffkins Group

We wanted to express our thanks to you for your assistance on the Ansarada project which recently won the Australian Interior Design Award for Best Workplace Design Australia Wide for 2014. The project was a particularly challenging one in terms of acoustics and you were able to realise our vision for the attenuation devices which formed the backbone of the project. The highly detailed nature of the install coupled with the intricate patterning of the acoustic devises demanded the kind of precision that would not normally be associated with a fit-out of a century old wool store however working together we managed to achieve a remarkable result. We thank you for lending your expertise to the project and look forward to working together in the future.

Ben Mitchell Those Architects

We engaged an acoustic consultant who specified the use of a variety of ceiling and wall treatments, all supplied by Keystone Acoustics which delivered not only amazing sound, but also gave us a finished look that is stunning. Catherine Pomiecko, Project & Marketing Manager at Keystone Acoustics worked with us from the beginning and provided exceptional service and advice, which resulted in a look and quality of sound that has not only met, but exceeded our expectations. Thank you Catherine and Keystone for adding your special magic to our home.

We at Epic Interiors Group recently completed the plasterboard and ceilings for 34 units at St Ives. We engaged the services of Key Industries Pty Ltd to carry out the supply and delivery of CFC. Key Industry works consisted of the supply of (CFC) compressed Fibre Cement. I found Key Industries are willing to co-ordinate with all of our demands and schedules to enable a smooth and time effective project. Shuria Agrawaal concentrated on ensuring our orders were correct and materials that were supplied were of 1st quality and exceeded the industry standards. His no problem attitude and salesmanship goes beyond the call of duty. Being in the construction industry, we are always given tight guidelines with timing, Key Industries managed to work well with us and nothing was ever a problem for them. Having successfully completing these works, I would have no hesitation in recommending the team from Key Industries for your projects.

Sam Galluzzo Epic Group

Needless to say but I seriously can not thank you, Shuria, Mark and the Keystones team for pulling us through for St Luke’s! You and Mark really got us on track through a tough situation and gave us a premium product as a result I cannot be more pleased We have used keystones every so often for the past 2-3 years and honest I can not be more pleased with customer service, quality of service and product you continue to provide. I will personally try to get keystones products as a option were applicable for any future projects! I will continue to refer you and your team especially, hopefully for many more years to come! Thanks from the Tramix team and have a good new year!

Chris Jin Tramix Pty Ltd

When Casello Pty Ltd was awarded the Carpentry package of the Ararat Prison (Vic) project, we were advised of a very large variation that needed to be installed in a very tight time frame. After several discussions with Catherine in relations to the details of the project, I engaged the services of Keystone Acoustics to carry out the manufacture, supply and delivery of the specified acoustics panels for the project. The scope of works and the very nature of the site and its location required a confidence in the supplier to produce a quality product and their ability to meet tight deadlines. It was comforting that throughout the project, we were able to communicate and work closely with Catherine Pomiecko who managed our requests and co-ordinated the supply of materials to site in a timely and professional manner, considering Catherine is Sydney based and all correspondence was via email and phone the job we could not have asked for an easier team to deal with. Casello Construction would have no hesitation in working with and recommending the Keystone Team for future projects.
