We are thrilled with our new outdoor area! We were impressed with the outstanding service from the beginning of the project, right through the build and up to the final stages. Gary was a great support in selling a product he is highly passionate about and knew would suit our needs. Matt and Mark kept up us to date throughout the build. They were efficient and considerate of our living space in and around the building project. The quality of the finished product has added value to our home and given us an outdoor extension of our living space that we look forward to enjoying all year round.

I am delighted with my new carport built by opal building services. Mark and Chris the builders impressed me with their attention to detail and professionalism. They answered all my questions, cleaned everything up after themselves, were on time and worked hard all day. This is the second project that opal building services have done for us and I would have no hesitation in trusting future projects to them. Highly recommended.

From the first consultation with Gary , we felt very comfortable and ensured of an outdoor space we wanted.He put our plans to work and the outcome is just what we wanted.. The installation with Mark and Jono was seamless, with the work done to perfection, they worked well together and always left a clean work space when finished. Thanks to all the team for a job well done..
