  Cosmo, Frank, and the team installed a hybrid floor in our apartment and did a fantastic job. They were professional, attentive, and took care of everything—from coordinating with various trades, providing specifications for strata approval, to recommending suitable materials and solutions. Best of all, they completed the entire project while we were away, so we returned to a beautifully finished new floor without any stress. I’ll definitely be looking forward to our next project with them. Thank you both.
