My husband and I cannot fault the service we received from design studio consultant Megan at the Central Coast showroom. She was so friendly throughout our initial emails, and couldn’t be more informative when I visited the showroom itself. I had been gathering multiple quotes from other local window suppliers and Megan really stood out from the rest.
