About SJB

Family-run quantity surveyors, on your side

SJB Quantity Surveyors & Tax Depreciation Consultants is a family-owned and operated practice founded by Steve Blank, with over 30 years' experience in the construction industry. We prepare ATO-compliant tax depreciation schedules for residential and commercial investment properties right across Australia.

We're mum-and-dad investors ourselves — not a faceless corporate. That means genuine attention to detail, honest advice, and a real person on the other end of the phone. We look after you at every step, making sure we maximise every cent you can legitimately claim.

Every schedule is prepared by qualified quantity surveyors, fully compliant with current ATO legislation, and backed by our SJB 200% Guarantee.
