I cannot say enough about the fantastic professional advice, support and service provided by Michael and his team, ASAP Waterproofing. Michael was very attentive to understanding our issue, damage to waterproofing caused by Cockatoo's, he investigated options to address and provided a cost effective solution which is acting as a deterrent as well. His solution has thus far, over 12 months later, proven to be highly effective. Thank you Michael and team. Strata Building SydneyPosted on Google![]()
