From initial quote with Gary, to approval with Kylie, Mark and his team Jamie, Chris & Ben went out of their way to get the job done and were thorough, careful and tidy from start to finish. The team provided great communication throughout the job. They're a happy bunch as well which was great to witness and work well together with speed and precision. I have no hesitation to recommend them to family and friends.

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.

Gary came initially to look at the sight and see what we were after. He was very knowledgeable about the products available and what we could do with regard to council. At opal they took the time to get the approvals required. Now our car port is finished and the job is great. I was very impressed with the guys who erected it also . They left the sight clean and any questions along the way they had answers for. Couldn’t praise the whole team enough.

Phil came to provide a quote for us and was incredibly professional and knowledgeable about the finer details for pergola, design choices and also council rules and regulations. He was open and honest about everything, which I found other businesses try to hide many details from you. I found his service outstanding and would recommend at least considering these guys.
