While they weren't the very cheapest of the quotes we got, the whole process of getting our windows replaced from Dolphin stood out from the competition from our very first contact. Paul, Joel and the whole team did an outstanding job of working with us to get new windows and a new front door which we are really happy with. It was reassuring dealing with the very experienced general manager and owner of the company which itself is well established and has a deserved good reputation.
We were really impressed with the quality of the product and none of the other companies who sent surveyors / salespeople bought a sample window to show us or left us with product literature or schematics of the proposed job. The turnaround time to install was really quick as we got the work done at a relatively quiet time of year, and the difference it has made to the appearance and energy efficiency of the house is fantastic. The installation team and everyone we dealt with was very knowledgeable, warm and friendly and we will happily recommend their services to our family and friends.
