Lonsdale Building Group had the simple task of rebuilding a 5m x 3m balcony with one minor leak. The result was a 100% disaster with major pooling and multiple water leaks causing substantial damage to sub-rooms. Worse than lacking building knowledge despite being a registered builder (DB-U 47215), company owner Nick Lonsdale demonstrated an utter lack of integrity. First blaming the tiler, then the sliding doors, then water coming from neighbouring units and, the last straw, blaming me for supposedly overriding his advice. Investigation by other building experts proved the new balcony was never properly reconstructed. Despite paying over $10K, Lonsdale Building Group and Nick Lonsdale have neither returned my money nor apologised. Instead, Nick said he could fix the problems if paid more. If you choose to deal with Lonsdale Building Group and Nick Lonsdale, believe nothing and document everything. The balcony has now been ripped up and rebuilt by a competent builder for an additional cost.
