“Our family home was built by Luke, Josh and their team, an experience which we enjoyed along the way for which not many would be able to say during their building journey. Luke and Josh were very personable and a joy to deal with and extremely easy going. I recommend their company and their expertise very highly.
Thank you Blitz for the wonderful experience!!!”

“Blitz Building Group has been an absolute pleasure to deal with from start to finish. From the first meeting,  they were friendly, professional, and knowledgeable. They gave a competitive quote and completed the work on a realistic time frame. All tradesmen working were well mannered, clean and skilled craftsmen. Could not recommend Luke and his time highly enough"

“Their modern, customer- focused approach to business was a fresh change and meant they were easily contactable and reliable throughout the project, and we were kept informed with the progress and schedule every step of the way. We want to thank Luke, Josh and their team. We are very happy with how everything has turned out, their attention to detail and the quality of their work. We have already recommended Blitz Building Group to several friends and neighbours, and we plan to get in contact again for future work"
