Bricklaying- 13 May 2018
Dan is a top bloke! Did a cracking good job of my wall, which was looking tired and in need of repointing before Dan did his magic. Dan initially came out to see what was needed and quoted a really fair price. Dan carried out the work when he said he would, taking time to do a really good job. Tidied up and cleaned all the area where he was working once he finished. All looks like new. Would certainly recommend Dan for all your building works!!!

My wife and I recently had a complete garden overhaul which involved leveling our garden, installing approximately 40 railway sleepers, laying a large Indian sandstone patio, and new lawn, all of which was completed in a little under two weeks. Nathan and Jimmy were a pleasure to have around, they were polite, professional, hard working , and always arrived on time. I would highly recommend NJC building services, their work is to an extremely high standard and they are only happy at the end of a project if the customer is happy. I will definitely recommend NJC Building Services to friends and family, and will also be using them next year when I intend to have a new driveway installed. Many thanks gents look forward to seeing you again in the future all the best.

Keith and the team were extremely helpful and professional throughout the entire process - from getting the right doors to meet my spec, to fitting them, to clearing up. I had specific requirements for the doors, and Keith was diligent and patient in taking on those requirements - and the end result was exactly what I wanted. Excellent job. I have no reservations in recommending Abacus.

Extensions- 14 Jan 2019
Kevin did a good job overall with our extension. The build had many of the challenges that should be expected with an old, idiosyncratic house, plus a few others too. In particular, Kevin's wealth of knowledge and experience with traditional building methods was invaluable. His ability to solve problems and offer intelligent advice on many different aspects of the build was also hugely appreciated. The job took longer than expected but in the end the result has made it worthwhile.
