  • Our 40 year old balustrades needed replacing due to safety and non-compliance. We sourced a number of quotes with Buildcore’s being the most detailed – this gave us confidence. I can’t fault Mark. He kept us appraised at every single stage, explaining what was happening and moving things forward. On site, Mark communicated well to all tenants and his team were friendly, helpful and kept the place clean. Since replacing our balustrades we have not looked back. It’s modernised the building, and everyone is happy. It’s also added value to the property in my opinion.

  • “Mark and his team from Buildcore delivered the most compelling presentation, formal proposal and final solution which consisted of the scaling back of (damage) and implementation of market leading materials. The project was superbly run with Mark at the helm. Communication was extremely professional and well managed both internally to residents and to surrounding apartments. Not a single complaint was received. Mark’s rigour of process delivered weekly project meetings ensuring our team were fully up to speed on weekly progress and management of the budget.”
