As the Owners Corporation Chair, my experience with the way the Immerge Group looks after a St Kilda building has been very positive. In times of urgent need, immediate attendance by a technician was provided. Communication with the office team has been excellent. I am especially impressed with Kellie and Brendan.

My husband dealt with Immerge Group when our hot water service packed it in. From the moment he rang them for a quote they were extremely helpful and knowledgeable and could answer all questions and give very good advice. The workmanship and time it took to replace and install our new unit was excellent and all done in the same day. Highly recommend Immerge Group, they were fantastic.

Our Rinnai hot water system stopped working after 3.5 years-6 months out of warranty! Rinnai arranged for Immerge Group to do the service call. David from Immerge attended our job and was fantastic. He contacted Rinnai and was able to get the repair done under warranty. he also noticed our gas regulator was faulty and advised us to contact our gas retailer. Thank you David you have gone above and beyond! Very very happy!
