As mentioned in other reviews, Darren does have a long lead time and we had to wait slightly over a year for our initial installation. We were very happy with the quality of work and particularly the kerbing and lighting. Courtney and the guys were fantastic, really friendly, helpful and approachable. Unfortunately, we had a bad batch of Marshalls blocks, and this is where I have been particularly pleased that we had chosen Darren. As an approved Marshalls contractor, once we raised our concerns, Darren referred the issue immediately to his contacts at Marshalls who in turn made several site visits and tested the blocks. Marshalls agreed to replace the blocks (with Darren as contractor), and the drive has now been re-laid. The finished drive now looks really good and we are very pleased with it. It was also nice to see some exceptional after sales service, with Darren arranging for some minor repairs and also to kindly replace a block that had an oil drip from a delivery driver.
