    "James and his team did a great job providing an accurate quote in no time, attending my job in a timely manner and finishing to the quality and budget they'd promised. All this happened during a challenging and special time of flooding and cyclone which was an exceptional job!
    Thanks James and the team! Highly recommended for the future jobs!

    "My experience with Genesis, James Mika’s company was very good. James organised butanol roof maintenance, scaffolding required, full roof paint, full exterior house paint and plaster maintenance as well as aluminium joinery painting. Most of this was done by James’ team but the plaster maintenance was done by Tony Selling from Homesmart who was amazing too. I was very fortunate that the entire maintenance was very professionally done and was great to deal with. James runs a very good business. I was advised by my solicitor to take the utmost care with who I employed and I am glad I chose James and Genesis."
