I had a really good experience with Ohana. From the initial meeting right throughout the process. Sam advised the best plan to fix the stormwater problem and the tradesmen carried out the work in a professional and timely manner. They cleaned up all the mess and removed all rubbish as well so the site looked as good as it could.they also top dressed the lawn so it can grow back quickly and neatly. They even left me a bag of top dressing to fill any low points as it recovers. They worked hard and finished late to get the job completed. They definitely went above and beyond.
