Extensions- 14 Oct 2025
Initially hired for professionalism and communication but that dwindled as the job progressed. Was told 4 week for completion, took nearly 14 with no apologies just an excuse of “delivery issues”. Workmanship is good and builders are pleasant and accommodating to have around your home. Price was competitive but not the cheapest we received

We engaged Civenco following a three way quote in which they were clearly competitive. What impressed us most was the professionalism and approachability of John and his team. When it came to the job itself they were timely, very competent and helpful throughout. They rectified minor snags quickly and were a pleasure to work with. I have no hesitation in recommending them.
