I had some fencing replaced, some crazy paving taken up and gravel put down and a gate erected by these guys. The work was done to a great standard with minimum fuss and in a timely fashion. They do not use any sub-contractors so you know who you are dealing with throughout the project. The site was left clean and tidy too so I am more than happy to recommend SNC Building and Maintenance Service for similar jobs.
