Just had security doors installed on my home by Chalmers Security. The whole process was seamless. The doors look fantastic. I'm so happy. Chris and Cameron did a great job on the installation. They were very courteous and professional. Completed the job in a timely manner. They explained everything to me regarding operation and also warranty. Took the rubbish away and cleaned up after the job. Stephen who came out and did the quote was open and honest. He gave me options and provided a detailed quote. Jennifer in the office was really efficient regarding keeping me informed during the whole process. The doors themselves were manufactured quickly so not a lot of waiting around either. All in all a very pleasant experience. ☺️Posted on Google![]()

Chalmers Security Installations supplied and installed a Prowler Proof external screen to a spare bedroom sash-style window that had not been able to be opened due to its 3rd level location with nothing underneath. CSI also supplied and installed a Prowler Proof hinged screen to the twin window in that room that does have an accessible roof. The complication for the most recent screen was needing to align with a major building repaint when scaffolding would be available. Stephen and Jennifer were extremely accommodating and patient and had the screen ready and able to get Chris (installer) to fit within a small time gap. I should add this was a minor piece of work from their perspective and they were responsive and flexible to get the job done. The increase in air flow is very noticeable and I don't have to worry about birds and other wildlife visiting that way.Posted on Google![]()
