We use a fully a transparent time and materials charging model, with all receipts available for inspection. All materials and products used in our services are purchased from reputable suppliers.
There is generally a shortage of materials in the industry, that's why we prefer to work with the larger suppliers, such as Bunnings, Mitre10 and Bills Board Factory.
Journey time taken to purchase materials is added to the final invoice, but we communicate all the way, so no surprises.
