NNW Property has been using Questa Services for nearly two years. During this time Igor and the team have proved to be extremely dependable and thorough in their work. In an industry that requires prompt action, Igor has shown time and time again that he can operate quickly and efficiently and we are very happy with the high standard of his work. We consider Questa Services as a part of our extended team and value his professionalism and attention to detail. I have no hesitation in recommending Questa to other agencies or individuals.

Jenny Groth, NNW Epping

We were first introduced to Igor Gavranovic of Questa Property Services when we sold a residential property in Riverview. Igor was the regular cleaner for the vendor. Riverview Realty found his work to be exceptional and his values equalled our business’ values. We have never used any other cleaning company since. We have relied on Questa’s services for the last three years and have found Igor and his team honest, reliable and hard working. Riverview Realty inherited a rental property that was in disrepair because of the tenant we had to evict. With hard work Igor and his team brought the property back to a level where we were able to gain a good rent for the landlord. For that we were really thankful that we had a great cleaning team.

When selling property presentation is the most important aspect of the campaign and we can’t recommend Questa Services enough. Igor and his team make sure our properties look their best, our clients are happy and they ensure they fit in with our sometimes very short deadlines. Finding a cleaning company you can trust is crucial when you are managing peoples biggest assets, and we have found that in Questa. Not to mention the end result is spotless – I even use them at my own house!
