"We recently had our home extended by Coastal Renovation Group and could not be happier with how it turned out. The team was easy to deal with, showed up when they said they would, and kept the place tidy throughout. Communication was clear the whole way through and the finish looks great. Would definitely recommend."
"From the first quote through to the final walk through, everything was handled professionally. The boys did a full extension for us and the quality of work really shows. No shortcuts and no dramas. They also finished pretty much on schedule which was a big plus."
"Absolutely thrilled with our rear extension. The open plan living area has completely transformed how we use our home. CRG managed the entire process including council approvals and we barely had to lift a finger. Highly professional from start to finish."
"Second to none in the Illawarra. We had a second storey addition completed and the result exceeded our expectations. The craftsmanship is exceptional and the team's communication throughout the build was outstanding."
