DSA Garage Doors Sydney - Location Map


I first heard of Door Systems Australia in 2009 from a family friend who had their garage door installed by your company. Being a supporter of our local businesses, I decided to get a quote from you guys and when Rob came out to measure and quote, I was very impressed by his design and decided to go ahead with the new door. The service was excellent and the job was completed to my satisfaction. It instantly added so much more value to my house. I had no problem selling that house in 2 days.

Thanks so much for the help with choosing our Garage Doors, we really appreciated the service. Once the new door went in it has made our house look modern & fresh. The Automation of the doors is fantastic, no more leaving the car out the front any longer. I can only imagine you have many satisfied customers. Once again we would like to thank you and your Team.

As a real estate agent with a large rent roll and my role being solely maintenance coordination, I rely on good trades people. Part of the team of trades people I use is Door Systems Australia. First National Hills Direct has appointed Vicki and Michael Renehan and their team to complete various jobs for over three years now. I have always found the team at DSA to be reliable and professional and I would not hesitate in recommending them to anyone who needs a new garage door/motor and/or repairs to an existing one.
